Asbestos in Construction

1.0  Introduction

An estimated 1.3 million employees in construction and general industry face significant asbestos exposure on the job. Heaviest exposures occur in the construction industry, particularly during the removal of asbestos during renovation or demolition. Employees are also likely to be exposed during the manufacture of asbestos products (such as textiles, friction products, insulation, and other building materials) and during automotive brake and clutch repair work. Asbestos is well recognized as a health hazard and is highly regulated.

2.0  Scope

These regulations apply to asbestos exposure in the following areas:

  • Demolition or recovery of structures where asbestos is present.
  • Removal or encapsulation of materials containing asbestos.
  • Construction, alteration, repair, maintenance, or renovation of structures that contain asbestos.
  • Installation of products containing asbestos.
  • Asbestos spill/emergency cleanup.
  • Transportation, disposal, and storage of asbestos at the site where construction activities are performed.
  • Housekeeping activities involving asbestos at the site where construction activities are performed.

3.0  Definitions

Aggressive method- removal or disturbance of building material by sanding, abrading, grinding or other method that breaks, crumbles, or disintegrates intact ACM.

Amended water- water to which a wetting agent has been added to increase the ability of the liquid to penetrate ACM.

Asbestos- includes chrysotile, amosite, crocidolite, tremolite asbestos, anthophyllite asbestos, actinolite asbestos, and any of these minerals that have been chemically treated and/or altered. For purposes of this standard, "asbestos" includes PACM.

Asbestos- containing material (ACM)- any material containing more than one percent asbestos.

Authorized person- any person authorized by the employer and required by work duties to be present in regulated areas.

Class I asbestos work- activities involving the removal of thermal system insulation (TSI) and surfacing ACM and PACM. These types of activities will not be conducted by university employees.

Class II asbestos work- activities involving the removal of ACM which is not thermal system insulation or surfacing material. This includes, but is not limited to, the removal of asbestos-containing wallboard, floor tile and sheeting, roofing and siding shingles, and construction mastics.

Class III asbestos work- repair and maintenance operations, where "ACM" including TSI and surfacing ACM and PACM, is likely to be disturbed.

Class IV asbestos work- maintenance and custodial activities during which employees contact but do not disturb ACM or PACM and activities to clean up dust, waste and debris resulting from Class I, II, and III activities.

Clean room- an uncontaminated room having facilities for the storage of street clothing and uncontaminated materials and equipment.

Closely resemble- the major workplace conditions which have contributed to the levels of historic asbestos exposure, and are no more protective than conditions of the current workplace.

Competent person- one who has received specialized training and is capable of identifying asbestos hazards in the workplace and selecting the appropriate control strategy for asbestos exposure and has the authority to take prompt corrective measures to eliminate hazards.

Critical barrier- one or more layers of plastic sealed over all openings into a work area or any other similarly placed physical barrier sufficient to prevent airborne asbestos from migrating to an adjacent area.

Decontamination area- an enclosed area adjacent and connected to the regulated area consisting of an equipment room, shower area, and clean room, that is used for the decontamination of workers, materials, and equipment.

Demolition- the wrecking or taking out of any load-supporting structural member and any related razing, removing, or stripping of asbestos products.

Disturbance- activities that disrupt, crumble, or generate visible debris from ACM or PACM. Disturbance includes cutting away small amounts of ACM and PACM that can be contained in one standard sized glove bag or waste bag in order to access a building component.

Employee exposure- that exposure to airborne asbestos that would occur if the employee were not using respiratory protective equipment.

Equipment room (change room)- a contaminated room located within the decontamination area that is supplied with impermeable bags or containers for the disposal of contaminated protective clothing and equipment.

Removal- all operations where ACM and/or PACM is taken out or stripped from structures or substrates, including demolition operations.

Renovation- the modifying of any existing structure or portion.

Repair- overhauling, rebuilding, reconstructing, or reconditioning of structures or substrates, including encapsulation or other repair of ACM or PACM attached to structures or substrates.

Surfacing material- material that is sprayed, troweled-on or applied to surfaces (such as acoustical plaster on ceilings and fireproofing materials on structural members).

Surfacing ACM- surfacing material which contains more than 1% asbestos.

Thermal system insulation (TSI)- ACM applied to pipes, fittings, boilers, breeching, tanks, ducts or other structural components to prevent heat loss or gain.

4.0  Permissible Exposure Limits (PELS)

Time-weighted average limit (TWA)

  1. Employees will not be exposed to an airborne concentration of asbestos in excess of 0.1 fiber per cubic centimeter of air as an eight (8) hour time-weighted average (TWA).

Excursion limit

  1. Employees will not be exposed to an airborne concentration of asbestos in excess of 1.0 fiber per cubic centimeter of air as averaged over a sampling period of thirty (30) minutes.
     

5.0  Multi-employer Worksites

  1. An employer performing work requiring the establishment of a regulated area shall inform other employers on the site of the nature of the work with asbestos and/or PACM, of the requirements pertaining to regulated areas, and measures taken to ensure that employees of the other employers are not exposed to asbestos.
  2. Asbestos hazards shall be abated by the contractor who created the source of asbestos contamination.
  3. All employers shall comply with applicable protective provisions to protect their employees. For example, if employees working immediately adjacent to a Class I asbestos job are exposed to asbestos due to inadequate containment, their employer shall either remove them from the area until the breach is repaired; or perform an initial exposure assessment.
  4. Employers of employees working adjacent to regulated areas shall check daily to determine the integrity of the enclosure and/or the effectiveness of the control method used by the asbestos contractor to assure that asbestos fibers do not migrate to adjacent areas.
  5. All general contractors on a construction project shall exercise general supervisory authority over the work covered by this standard, even if the general contractor is not qualified to serve as the asbestos "competent person." As supervisor of the entire project, the general contractor shall determine if the asbestos contractor is in compliance with this standard.

6.0  Regulated Areas

  1. All Class I, II and III asbestos work will be conducted within regulated areas. Class IV operations will be conducted in a regulated area if airborne concentrations of asbestos may exceed a PEL.
  2. The regulated area will be demarcated in any manner that minimizes the number of persons within the area and protects persons outside the area from exposure to airborne asbestos. If critical barriers or negative pressure enclosures are used, they may demarcate the regulated area. Appropriate signage will be displayed.
  3. Access to regulated areas will be limited to authorized persons.
  4. All persons entering a regulated area where they are required to wear respirators will be supplied with an appropriate respirator.
  5. Employees will not eat, drink, smoke, chew tobacco or gum, or apply cosmetics in the regulated area.
  6. Asbestos work performed within regulated areas will be supervised by a competent person.

7.0  Exposure Assessments and Monitoring

General monitoring

  1. Where exposure monitoring is required, determinations of exposure will be made from breathing zone air samples that are representative of the 8-hour TWA and 30-minute short-term exposures of each employee.
  2. Representative 8-hour TWA exposures will be determined on the basis of one or more samples representing full-shift exposure for employees in each work area. Representative 30-minute short-term exposures will be determined on the basis of one or more samples representing 30-minute exposures associated with operations that are most likely to produce exposures above the excursion limit for employees in each work area.

Initial exposure assessment

  1. A "competent person" will conduct an exposure assessment immediately before or at the initiation of an operation that may expose a worker to asbestos to determine expected exposures. The assessment must be completed in time to comply with requirements which are triggered by exposure data or the lack of a "negative exposure assessment," and to provide information to assure that all control systems are appropriate for that operation and will work properly.
  2. Unless a negative exposure assessment has been made, the initial exposure assessment will, if feasible, be based on employee exposure monitoring The assessment will take into consideration the monitoring results and all information which indicate employee exposure to asbestos, including any previous monitoring which indicate the levels of asbestos likely to be encountered on the job.


Negative exposure assessment

  1. For any one specific asbestos job, employee exposures may be shown to be below the PELs by data that conforms to the following criteria:

Objective data demonstrating that the material cannot release airborne fibers in concentrations exceeding the PELs under work conditions having the greatest potential for releasing asbestos.
Where exposure monitoring of a prior asbestos job was performed within 12 months, monitoring was performed in compliance with the asbestos standard; and the data were obtained under conditions that "closely resemble" those used in the current operations, the operations were conducted by employees whose training and experience are similar to that of current employees, and these data show that under the current conditions it is unlikely that the PEL will be exceeded.
The results of initial exposure monitoring of the current job made from breathing zone air samples that are representative of the 8-hour TWA and 30-minute short-term exposures of each employee covering operations which are most likely to result in exposures over the PELs.

Periodic monitoring

  1. Daily monitoring will be conducted that is representative of the exposure of each employee performing Class I or II work unless a negative exposure assessment for the operation has been made.
  2. For Class III and IV operations periodic monitoring will be conducted of all work where exposures are expected to exceed a PEL, at intervals sufficient to document the validity of the exposure prediction. When all employees required to be monitored daily are equipped with supplied-air respirators, or other positive pressure mode respirator, daily monitoring is not necessary.
  3. Exposure monitoring will be performed whenever there has been a change in personnel or work practices that may result in additional exposures above the PELs. Such additional monitoring is required regardless of whether a "negative exposure assessment" was previously produced for a specific job.

Termination of monitoring

  1. If the periodic monitoring reveals that employee exposures are below the permissible exposure limit and excursion limit, monitoring may be discontinued for those employees whose exposures are represented by the monitoring.

Employee notification of monitoring results

  1. Affected employees will be notified of monitoring results as soon as possible following receipt of monitoring results.
  2. Affected employees will be notified of the results of monitoring in writing either individually or by posting at a centrally located place.

Observation of monitoring

  1. Affected employees and their designated representatives will be provided with an opportunity to observe any monitoring of employee exposure to asbestos.
  2. When observation of the monitoring of employee exposure to asbestos requires entry into an area where the use of protective clothing or equipment is required, the observer shall use such clothing and equipment.

8.0 Methods of Compliance

General Engineering controls and work practices

  1. The following engineering controls and work practices will be used in all operations regardless of the levels of exposure:
    1. Vacuum cleaners equipped with HEPA filters to collect all debris and dust containing ACM and PACM, except for roofing material.
    2. Wet methods to control employee exposures during asbestos handling, removal, cutting, and cleanup, except where the use of wet methods are not feasible or will create safety hazards.
    3. Prompt clean-up and disposal of wastes and debris contaminated with asbestos in leak-tight containers, except in roofing operations.
  2. In addition to the above measures, the following control methods will be used to achieve compliance with the PELs:
    1. Local exhaust ventilation equipped with HEPA filter dust collection systems.
    2. Enclosure or isolation of processes producing asbestos dust.
    3. Ventilation of the regulated area to move contaminated air away from the breathing zone of employees and toward a filtration or collection device equipped with a HEPA filter.
  3. When engineering and work practice controls described above are not sufficient to reduce employee exposure below the PELs, they shall be used to reduce exposures to the lowest levels attainable and shall be supplemented by the use of respiratory protection.
  4. The following work practices and engineering controls will not be used for work related to asbestos, regardless of levels of exposure or the results of initial exposure assessments:
    1. High-speed abrasive disc saws that are not equipped with point of cut ventilator or enclosures with HEPA filtered exhaust air.
    2. Compressed air used to remove asbestos, unless the compressed air is used in conjunction with an enclosed ventilation system designed to capture the dust created by the compressed air.
    3. Dry sweeping, shoveling or other dry clean-up of dust and debris containing ACM and PACM.
    4. Employee rotation as a means of reducing employee exposure to asbestos.

Work practices and engineering controls for class II work

  1. All Class II work will be supervised by a competent person.
  2. For all indoor Class II jobs, where a negative exposure assessment has not been produced, or if changed conditions indicate there may be exposure above the PEL or where ACM is not removed in a substantially intact state, one of the following methods will be used to ensure that airborne asbestos does not migrate from the regulated area:
    1. Critical barriers will be placed over all openings to the regulated area.
    2. Another barrier or isolation method will be used which prevents the migration of airborne asbestos from the regulated area, as verified by perimeter area monitoring or clearance monitoring.
  3. Impermeable dropcloths will be placed on surfaces beneath all removal activity.

    1. A competent person shall evaluate the work area, the projected work practices and the engineering controls, and shall certify in writing, that the different or modified controls are adequate to reduce employee exposure to below the PELs under all expected conditions and the method meets the requirements of this standard. The evaluation shall be based on data representing employee exposure during the use of the method under conditions which closely resemble those which will be used for the current job, and by employees whose training and experience are equivalent to employees who will perform the job.

Work practices and engineering controls for Class III asbestos work

  1. Class III asbestos work will be conducted using engineering and work practice controls which minimize exposure to employees.
  2. The work will be performed using wet methods.
  3. To the extent feasible, the work will be performed using local exhaust ventilation.

  4. No employee shall use a respirator if a physician determines that the safety or health of the employee will be impaired by the use of a respirator. The employee will be assigned to another job or given the opportunity to transfer to a different position, in the same geographical area, and with the same seniority, status, and rate of pay and other job benefits he or she had just prior to such transfer, if such a position is available.

Respirator fit testing

  1. The respirator issued to the employee will exhibit the least possible facepiece leakage and fit properly.
  2. A quantitative or qualitative fit test will be preformed by the Safety Office at the time of initial fitting and at least every six months thereafter for each employee wearing a negative-pressure respirator. The qualitative fit tests may be used only for testing the fit of half-mask respirators or of full-facepiece respirators where they are worn at levels at which half-facepiece respirators are permitted.

10.0 Protective Clothing

  5. Dry brushing is prohibited.

Lead in Construction

1.0 Introduction

In the construction industry, most over-exposures to lead are found in the trades, such as plumbing, welding, electrical work, carpentry, and painting. Significant lead exposures can also arise from removing paint from surfaces previously coated with lead-based paint, such as in renovation and demolition. Once in the blood, lead is distributed primarily in the blood, soft tissue (kidney, bone marrow, liver, and brain) and bones and teeth and can build to toxic levels.

2.0 Scope

This section applies to all construction work where an employee may be occupationally exposed to lead. Construction work is defined as work for construction, alteration and/or repair, including painting and decorating. It includes but is not limited to the following:

  • Demolition or salvage of structures where lead is present.
  • Removal or encapsulation of materials containing lead.
  • New construction, alteration, repair, or renovation of structures that contain lead.
  • Installation of products containing lead.
  • Lead contamination/emergency cleanup.
  • Transportation, disposal, storage, or containment of lead on the site or location at which construction activities are performed.
  • Maintenance operations associated with the construction activities described in this program.

3.0 Definitions

Action level- Employee exposure, without regard to the use of respirators, to an airborne concentration of lead of 30 micrograms per cubic meter of air calculated as an 8-hour time-weighted average (TWA).

Competent person- A person who is capable of identifying lead hazards and has authorization to take prompt corrective measures to eliminate them.

Lead- Metallic lead, all inorganic lead compounds, and organic lead soaps. Excluded from this definition are all other organic lead compounds.

4.0 Permissable Exposure Limit

  1. No employee will be exposed to lead at concentrations greater than fifty micrograms per cubic meter of air (50 ug/cubic meter ) averaged over an 8-hour period.
  2. If an employee is exposed to lead for more than 8 hours in any work day the allowable exposure, as a time weighted average (TWA) for that day, shall be reduced according to the following formula: Allowable employee exposure (in ug/cubic meter) = 400 divided by hours worked in the day.
  3. When respirators are worn, employee exposure will be based on the protection factor of the respirator. These levels will be averaged with exposure levels during periods when respirators are not worn to determine the employee's daily TWA exposure.

5.0 Exposure Assessment

General

  1. The Safety Office will conduct initial monitoring to determine if an employee is exposed to lead above the action level.
  2. Employee exposure is the exposure that would occur if the employee were not using a respirator.
  3. Where monitoring is required, the Safety Office will collect personal samples representative of a full shift. At least one sample for each job classification in each work area for each shift or the shift with the highest exposure level will be included.
  4. Full shift personal samples shall be representative of the monitored employee's regular, daily exposure to lead.

Protection of employees during assessment of exposure

1. Until the Safety Office performs an exposure assessment and documents that an employee performing any of the tasks listed below is not exposed above the PEL (50 ug/cubic meter), the employee will be assumed to be exposed above the PEL, but less than ten times the PEL. The tasks covered by this requirement are:

  • Where lead containing coatings or paint are present. Manual demolition of structures (e.g., dry wall), manual scraping, manual sanding, heat gun applications, and power tool cleaning with dust collection systems.
  • Spray painting with lead paint.

2. For the tasks listed below, until an exposure assessment is performed that demonstrates that employees are not exposed in excess of 500 ug/cubic meter, employees will be assumed to be exposed to lead in excess of 500 ug/cubic meter. If employees are exposed to levels of lead below 500 ug/cubic meter, exposed employees will be provided with the appropriate respirator. The tasks covered by this requirement are:

  • Using lead containing mortar; lead burning.
  • Where lead containing coatings or paint are present: rivet busting; power tool cleaning without dust collection systems; cleanup activities where dry expendable abrasives are used; and abrasive blasting enclosure movement and removal.

3. For the tasks listed below, until an exposure assessment is performed that demonstrates that employees are not exposed in excess of 2,500 ug/cubic meters (50 x PEL), employees will be assumed to be exposed in excess of 2,500 ug/cubic meters. If employees are exposed to levels of lead below 2,500 ug/cubic meters, employees will be provided with appropriate respirators. Interim protection as described in this paragraph is required where lead containing coatings or paint are present on structures when performing:

  • Abrasive blasting
  • Welding
  • Cutting
  • Torch burning

4. With regard to tasks not listed above, if there is any reason to believe that workers may be exposed to lead in excess of the PEL, workers will be treated as if they were exposed above the PEL until an exposure assessment is performed that demonstrates exposures below the PEL.

5.  For the tasks not listed above, if objective data is available demonstrating that a particular product containing lead or a specific process, operation or activity involving lead cannot result in exposure to lead above the action level this data may be used instead of implementing initial monitoring. An accurate record shall be maintained documenting the nature and relevancy of objective data, where used in assessing employee exposure instead of exposure monitoring.

6.  Until an employee exposure assessment is performed that determines actual exposure, employees performing the tasks described above will be provided with interim protection as follows:

  • Appropriate respiratory protection.
  • Appropriate personal protective clothing and equipment.
  • Change areas.
  • Hand washing facilities.
  • Biological monitoring to consist of blood sampling and analysis for lead and zinc protoporphyrin levels.
  • Hazard Communication and respiratory training.

Basis of initial determination

1. Initial determinations of employee exposure will be based on exposure monitoring results and any of the following, relevant considerations:

  • Any information, observations, or calculations which would indicate employee exposure to lead.
  • Any previous measurements of airborne lead.
  • Any employee complaints of symptoms which may be attributable to exposure to lead.

2. Monitoring for the initial determination may be limited to a representative sample of the exposed employees who are exposed to the greatest airborne concentrations of lead in the workplace.

3. If previous monitoring for lead exposures was performed within the past 12 months using work operations that closely resemble the type of material, control methods, work practices, and environmental conditions used in the current operations, the earlier monitoring results may be used to satisfy the requirements of this section if the sampling and analytical methods meet the required accuracy and confidence levels.

Positive initial determination and initial monitoring

1. If an initial determination shows the possibility of any employee exposure at or above the action level, monitoring which is representative of the exposure for each employee in the workplace who is exposed to lead will be conducted.

Negative initial determination

1. Where an initial determination is made that no employee is exposed to airborne concentrations of lead at or above the action level a written record will be made. The record shall include the date of determination, location within the worksite, and the name and social security number of each employee monitored.

Frequency

1. If the initial determination reveals employee exposure below the action level, further exposure determination will not be repeated unless there is a change in the task.

2. If the initial determination or subsequent determination reveals employee exposure above the action level but below the PEL, monitoring will be performed at least every 6 months. Monitoring will be continued at the required frequency until at least two consecutive measurements, taken at least 7 days apart, are below the action level at which time monitoring may be discontinued unless there has been a change in the task.

3. If the initial determination reveals that employee exposure is above the PEL, monitoring will be performed quarterly. Monitoring will continue at the required frequency until at least two consecutive measurements, taken at least 7 days apart, are below the PEL but above the action level.

Additional exposure assessments

1.

Mold

1.0 Introduction

Molds are fungi that can be found both indoors and outdoors. Molds grow best in warm, damp, and humid conditions, and spread and reproduce by making spores; which can survive harsh environmental conditions, such as drought, that do not support normal mold growth.

Molds are found in virtually every environment and can be detected, both indoors and outdoors, year round. Mold growth is encouraged by warm and humid conditions. Outdoors they can be found in shady, damp areas or places where leaves or other vegetation is decomposing. Indoors they can be found where humidity levels are high, such as basements or showers.

Mold will grow in places with a lot of moisture, such as around leaks in roofs, on ceiling tiles, around windows, or pipe insulation, or where there has been flooding. Mold grows well on paper products, cardboard, ceiling tiles, and wood products. Mold can also grow in dust, paints, wallpaper, insulation, drywall, carpet, fabric, and upholstery.

Mold can enter your space through open doorways, windows, vents, and heating and air conditioning systems. Mold in the air outside can also attach itself to clothing, shoes, bags, and pets can and be carried indoors.

If mold is growing in your office or dormitory, you should contact Facilities Management to have the mold removed and have the moisture problem corrected. Mold growth can be removed from hard surfaces with commercial products, soap and water, or a bleach solution of no more than 1 cup of bleach in 1 gallon of water.

Mold growth, which often looks like spots, can be many different colors, and can smell musty. Since the effect of mold on people can vary greatly, either because of the amount or type of mold, you cannot depend on sampling alone to know your health risk. The best practice is to remove the mold and work to prevent future growth.

2.0 Health Effects

Fungal diseases may sound mysterious and dangerous, but often they cause familiar infections. Yeast infections, thrush, ring worm, eye, lung, skin, hair, and nail infections can all be caused by fungi. Fungi are lurking everywhere and interact with humans, animals, and plants in a variety of ways. Some of these interactions can be beneficial; for example, both penicillin and bread, wine and beer use ingredients made from fungi. However, certain types of fungi can be harmful to health. Like bacteria and viruses, some fungi can act as pathogens. Human fungal diseases can occur due to infection or fungal toxins.

Fungi can be found in plants, soil, the environment, certain trees, decaying vegetation, and decomposing organic matter, even on our skin, mucus membranes and intestinal tract. Symptoms for fungal diseases can be as common as itching, coughing, fever, wheezing, but they can also be as serious as meningitis or even death.

Exposure to damp and moldy environments may cause a variety of health effects, or none at all. In general people should avoid areas that are likely to have mold, such as compost piles, cut grass, and wooded areas.

Some people are sensitive to molds. For these people, exposure to molds can cause symptoms such as nasal stuffiness, throat irritation, eye irritation, coughing or wheezing, or in some cases skin irritation. People with mold allergies may have more severe reactions. Immune-compromised people and people with chronic lung illnesses, such as obstructive lung disease, may get serious infections in their lungs when they are exposed to mold. Severe reactions may occur among workers exposed to large amounts of molds in occupational settings, such as farmers working around moldy hay. Severe reactions may include fever and shortness of breath. Some people with chronic lung illnesses, such as obstructive lung disease, may develop mold infections in their lungs.

If you believe you are ill because of exposure to mold in the building where you work, you should first consult your health care provider to determine the appropriate action to take to protect your health and will decide whether you need referral to a specialist. Such specialists might include an allergist who treats patients with mold allergies or an infectious disease physician who treats mold infections. If an infection is in the lungs, a pulmonary physician might be recommended. Patients who have been exposed to molds in their workplace may be referred to an occupational physician.

Notify your supervisor or residence director about your concern so that appropriate action can take place to clean up and prevent mold growth. To find out more about mold, remediation of mold, or workplace safety and health guidelines and regulations, you may also want to contact your local (city, county, or state) health department.

3.0 Prevention and Control

In your office or dormitory you can control mold growth by:

  • Controlling humidity levels;
  • Promptly fixing leaky roofs, windows, and pipes;
  • Thoroughly cleaning and drying after flooding, carpet cleaning, etc.;
  • Ventilating shower, laundry, and cooking areas.

If you choose to use bleach to clean up mold:

  • Never mix bleach with ammonia or other household cleaners. Mixing bleach with ammonia or other cleaning products will produce dangerous, toxic fumes.
  • Open windows and doors to provide fresh air.
  • Wear non-porous gloves and protective eye wear.
  • Consult the U.S. Environmental Protection Agency (EPA) guide titled Mold Remediation in Schools and Commercial Buildings. http://www.epa.gov/mold/mold_remediation.html
  • Always follow the manufacturer’s instructions when using bleach or any other cleaning product.

  • Keep humidity levels as low as you can—no higher than 35%--all day long. An air conditioner or dehumidifier will help you keep the level low. Bear in mind that humidity levels change over the course of a day with changes in the moisture in the air and the air temperature, so you will need to check the humidity levels more than once a day.
  • Use an air conditioner or a dehumidifier during humid months.
  • Be sure your area has adequate ventilation, including exhaust fans.
  • Add mold inhibitors to paints before application.
  • Clean bathrooms with fungicidal products.
  • Do not carpet bathrooms and basements.
  • Remove or replace previously soaked carpets and upholstery.

4.0 Inspections and Sampling

Generally, it is not necessary to identify the species of mold growing in your space. Current evidence indicates that allergies are the type of diseases most often associated with molds. Since the susceptibility of individuals can vary greatly either because of the amount or type of mold, sampling and culturing are not reliable in determining your health risk. If you are susceptible to mold and mold is seen or smelled, there is a potential health risk; therefore, no matter what type of mold is present, you should arrange for its removal.

Furthermore, standards for judging what is an acceptable, tolerable, or normal quantity of mold, have not been established. Also, the results of samples taken in your unique situation cannot be interpreted without physical inspection of the contaminated area or without considering the building’s characteristics and the factors that led to the present condition.

However, if you believe you are experiencing a mold problem in your office or dormitory you should contact the safety office to conduct a visual inspection of the area to confirm the presence and identify the source if possible. In the event that mold cannot be visually confirmed and there are no significant signs of related moisture issues; leaks, stained ceiling tiles, etc. then air sampling may be necessary to confirm the presence of a mold problem based on the relative indoor/outdoor concentrations.

Common Indoor molds

  • Aspergillus  A blue-green to brown mold. It is commonly found in soil, plant debris, and building materials. Causative agent of Aspergillosis.
  • Alternaria A dark brown mold. Grows readily in plant debris and soil.
  • Cladosporium A dark green to black mold. Found commonly airborne and in decaying vegetable matter.
  • Penicillium A bluish green mold. It is found most abundantly in the soil and plant material, specifically fruits and vegetables. Used medicinally as an antibiotic.

“Toxic” Black Mold

  • Stachybotrys  A greenish-black mold. It can grow on material with a high cellulose and low nitrogen content, such as fiberboard, gypsum board, paper, dust, and lint. Growth occurs when there is moisture from water damage, excessive humidity, water leaks, condensation, water infiltration, or flooding. Constant moisture is required for its growth.

Silica

1.0 Introduction

This program is designed to reduce or eliminate workplace exposure to crystalline silica. Exposure to crystalline silica can cause silicosis, a serious lung disease. More than one million U.S. workers, including over 100,000 in high risk settings, are occupationally exposed to crystalline silica. A wide range of industries use silica, including construction, mining, maritime industries, foundries, ceramics and glass manufacturing, electronics, agriculture, rock quarry/crushing and abrasives manufacturing.

2.0 Potentical Exposures

The following activities may cause crystalline silica dust to be present in the air:

  • Sawing, hammering, cutting, drilling, grinding, and chipping of concrete or masonry
  • Chipping, hammering, and drilling rock
  • Dry sweeping or pressurized air blowing of concrete, rock, or sand dust
  • Crushing, loading, hauling, and dumping rock
  • Sandblasting
  • Demolition of concrete and masonry structures
  • Concrete mixing
  • Working with ceramics, clay, and pottery

3.0 Materials containing Silica

  1. A product that contains silica must be labeled if the product contains more than 0.1% silica that may be hazardous when used.
  2. The machines used in the operations must be labeled with warning signs indicating silica is being used.
  3. If a material or product contains crystalline silica in quantities greater than 0.1%, there must be a material safety data sheet for it.

4.0 Air Monitoring

  1. The Safety Office will inspect each worksite and work operation to determine if employees are exposed to silica above the PEL. Indicators that an evaluation of employee exposure should be undertaken include:
    1. Information or observation which would indicate employee exposure to silica.
    2. Employee complaint of symptoms which may be attributed to exposure to silica.
    3. Change which may result in an increase in the airborne concentration of silica.
  2. The Safety Office will conduct air monitoring to measure worker exposures and ensure that engineering controls and respiratory protection are providing adequate protection.
  3. Air monitoring information will be made available to workers.
  4. Employees will wear a cyclone assembly and sampling pump throughout the work shift for up to eight hours. Dust samples will be collected from the worker’s breathing zone.
  5. The method of monitoring and analysis will have an accuracy of at least plus or minus 25% for concentrations of airborne silica equal to or greater than the PEL.
  6. If employees are exposed to silica in excess of the PEL monitoring will be repeated quarterly.

5.0 Exposure Limit

  1. OSHA regulations 1910.1000 Table Z-3 will be used to determine the permissible exposure limits for crystalline silica.
  2. The OSHA PELs for crystalline silica are 10mg/m3 divided by the percent of silica in the dust +2 (respirable), and 30 mg/m3 divided by the percent of silica in the dust +2 (total dust). For cristobalite and tridymite, the same formula will be used to determine the PELs, divided by one-half.
  3. NIOSH and ACGIH recommended exposure limits will be considered when determining employee exposure. The recommended NIOSH limit is 0.05 mg/m3 and the ACGIH recommendations are:
    1. 0.05 mg/m3 for cristobalite
    2. 0.1 mg/m3 for quartz
    3. 0.05 mg/m3 for tridymite
    4. 0.1 mg/m3 of contained tripoli respirable quartz

6.0 Medical Surveillance

1. Medical examinations will be made available:

  • To employees prior to their assignment in areas in which airborne concentrations of silica are above the PEL.
  • At least annually for each employee exposed to airborne concentrations of silica above the PEL at any time during the preceding six months.
  • Immediately, upon notification by the employee, that the employee has developed signs or symptoms commonly associated with chronic exposure to silica.

2. The medical examination will include a medical and occupational history to elicit data on signs and symptoms of respiratory disease prior to exposure to silica. A chest x-ray and PFT will be performed at the physicians discretion. The chest x-ray will be read by a certified class "B" reader.

3. A chest x-ray will be obtained on employment termination.

4. Where medical examinations are preformed, the following information will be provided to the examining physician:

  • The reason for the medical examination.
  • A description of the affected employee’s duties as they relate to the employee’ s exposure.
  • The results of the employee’s exposure measurements, if available.
  • The employee’s anticipated or estimated exposure level.

5. The Safety Office will obtain and furnish the employee with a written opinion from the examining physician containing the following:

  • The signs or symptoms of silica exposure displayed by the employee.
  • A report on the findings of the chest x-ray and PFT test.
  • The physician’s opinion as to whether the employee has any medical condition which would place the employee at increased risk from exposure to silica or would aggravate any medical condition.
  • Any recommended limitation upon the employee’s exposure to silica or upon the use of PPE and respirators.
  • A statement that the employee has been informed by the physician of any medical condition which requires further examination or treatment.

6. The written opinion will not reveal specific findings or diagnoses unrelated to occupational exposure to silica.

7.0 Safe Work Practices

1. The primary means of protecting workers will be through the use of less toxic materials, enclosed systems, local exhaust ventilation, wet methods, and good work practices.

2. The following measures will be used to reduce exposure to crystalline silica in the workplace:

  • Wet down the dust at the point of generation.
  • Install local exhaust ventilation to prevent dust from being released into the air.
  • During rock drilling, flow water through the drill stem.
  • Install dust collection systems onto machines or equipment that generated dust.
  • Use concrete/masonry saws that provide water to the blade.

3. Silica sand or other substances containing more than 1% crystalline silica will not be used for abrasive blasting.

4. Good personal hygiene will be practiced to avoid unnecessary exposure. Eating, drinking, use of tobacco products, or applying cosmetics will not be done in areas where there is dust containing crystalline silica.

5. If possible, employees will shower and change into clean clothes before leaving the worksite to prevent contamination of cars, homes, and other work areas.

8.0 Personal Protective Equipment

1. When source controls cannot keep exposures below the PEL, respiratory protection will be used.

2. When respirators are used, the Safety Office will enroll workers in a comprehensive Respiratory Protection Program. Important elements of this program are:

  • Periodic environmental monitoring.
  • Training of personnel.
  • Selection of proper NIOSH approved respirators.
  • An evaluation of the worker’s ability to perform the work while wearing a respirator.
  • Respirator fit testing.
  • Maintenance, inspection, cleaning, and storage of respiratory protection equipment.

3. A respirator approved for protection against crystalline silica-containing dust will be used.

4. If possible, disposable or washable protective clothes will be worn at the worksite.

9.0 Housekeeping Program

Exposed surfaces will be maintained free of accumulation of silica dust. To minimize hazards, the following procedures will be used to clean areas contaminated with dust containing crystalline silica:

  • Clean floors daily with a wet mop, wet pickup vacuum, or a HEPA filtered vacuum cleaner. The most effective method is with a HEPA vacuum cleaner.
  • Never sweep, dry mop, use compressed air, or use a regular vacuum cleaner. Regular vacuum cleaners are not suitable because they filter out heavy particles, allowing the finer more hazardous particles to pass into the air.
  • Clean shelves with a damp sponge or a HEPA vacuum cleaner.
  • Used filters should be carefully placed in a double plastic bag and disposed in the regular trash. Wear the proper respirator when changing filters.

10.0 Training

1. Workers who may be exposed to silica will receive safety training to include the following:

  • Information about the potential health effects of exposure to respirable crystalline silica.
  • Material safety data sheets for silica, masonry products, alternative abrasives, and other hazardous materials.
  • Instruction about the purpose and set-up of regulated areas marking the boundaries of work areas containing crystalline silica.
  • Information about safe handling, labeling, and storage of toxic materials.
  • Discussion about the importance of substitution, engineering controls, work practices, and personal hygiene in reducing crystalline silica exposure.
  • Instruction about the use and care of appropriate personal protective equipment (including protective clothing and respiratory protection).

2. Training will be conducted by the Safety Office. Training records will be kept in the Safety Office for three years.

3. Training will be performed prior to the employee’s assignment to an area where the employee may be exposed to silica. Retraining will be performed if the Safety Manager or supervision believes it is necessary to prevent or reduce exposures.

11.0 Warning Signs

  1. Warning signs will be posted to mark the boundaries of work areas contaminated with crystalline silica. These signs will warn workers about the hazard and specify any protective equipment required.
  2. The sign will contain the following words or similar words: Warning- Crystalline Silica Work Area- Improper handling or exposure to the dust may cause silicosis and death- Respirator Required.
