What Is Asbestos?Asbestos is a widely used, mineral-based material that is resistant to heat and corrosive chemicals. Typically, asbestos appears as a whitish, fibrous material which may release fibers that range in texture from coarse to silky; however, airborne fibers that can cause health damage may be too small to see with the naked eye. For more information, see our main asbestos information page for employers or for consumers and homeowners. You may also want the page on homeowners with asbestos shingles.
Who Is Exposed?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.
What Are the Dangers of Asbestos Exposure?Exposure to asbestos can cause asbestosis (scarring of the lungs resulting in loss of lung function that often progresses to disability and to death); mesothelioma (cancer affecting the membranes lining the lungs and abdomen); lung cancer; and cancers of the esophagus, stomach, colon, and rectum.
What Protections Are Mandatory?The U.S. Occupational Safety and Health Administration (OSHA) has issued revised regulations covering asbestos exposure in general industry and construction. Both standards set a maximum exposure limit and include provisions for engineering controls and respirators, protective clothing, exposure monitoring, hygiene facilities and practices, warning signs, labeling, recordkeeping, and medical exams.
Nonasbestiform tremolite, anthophyllite, and actinolite were excluded from coverage under the asbestos standard in May 1992.
Here are some of the highlights of the revised rules, published in the Federal Register June 20, 1986; and on Sept. 14, 1988:Permissible Exposure Limit: In both general industry and construction, workplace exposure must be limited to 0.2 fibers per cubic centimeter of air (0.2 f/cc), averaged over an eight-hour work shift. The excursion or short-term limit is one fiber per cubic centimeter of air (1 f/cc) averaged over a sampling period of 30 minutes.Exposure Monitoring: , employers must do initial monitoring for workers who may be exposed above the "action level" of 0.1 f/cc. Subsequent monitoring must be conducted at reasonable intervals, in no case longer than six months for employees exposed above the action level., daily monitoring must be continued until exposure drops below the action level (0.1 f/cc). Daily monitoring is not required where employees are using supplied-air respirators operated in the positive pressure mode.
Methods of Compliance: In both general industry and construction, employers must control exposures using engineering controls, to the extent feasible. Where engineering controls are not feasible to meet the exposure limit, they must be used to reduce employee exposures to the lowest levels attainable and must be supplemented by the use of respiratory protection.Respirators: In general industry and construction, the level of exposure determines what type of respirator is required; the standards specify the respirator to be used.Regulated Areas: In general industry and construction, regulated areas must be established where the 8-hour TWA or 30-minute excursion values for airborne asbestos exceed the prescribed permissible exposure limits. Only authorized persons wearing appropriate respirators can enter a regulated area. In regulated areas, eating, smoking, drinking, chewing tobacco or gum, and applying cosmetics are prohibited.must be displayed at each regulated area and must be posted at all approaches to regulated areas.
Labels: Caution labels must be placed on all raw materials, mixtures, scrap, waste, debris, and other products containing asbestos fibers.Recordkeeping: The employer must keep an accurate record of all measurements taken to monitor employee exposure to asbestos. This record is to include: the date of measurement, operation involving exposure, sampling and analytical methods used, and evidence of their accuracy; number, duration, and results of samples taken; type of respiratory protective devices worn; name, social security number, and the results of all employee exposure measurements. This record must be kept for 30 years.Protective Clothing: For any employee exposed to airborne concentrations of asbestos that exceed the PEL, the employer must provide and require the use of protective clothing such as coveralls or similar full-body clothing, head coverings, gloves, and foot covering. Wherever the possibility of eye irritation exists, face shields, vented goggles, or other appropriate protective equipment must be provided and worn., there are special regulated-area requirements for asbestos removal, renovation, and demolition operations. These provisions include a negative pressure area, decontamination procedures for workers, and a "competent person" with the authority to identify and control asbestos hazards. The standard includes an exemption from the negative pressure enclosure requirements for certain small scale, short duration operations provided special work practices prescribed in an appendix to the standard are followed.
