Asbestos Safety Information from Occupational Safety and Health Administration
Asbestos is well recognized as a health hazard and is highly regulated. 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.
OSHA and Environmental Protection Agency (EPA) asbestos rules are intertwined.
