Exposure monitoring samples must be analyzed by Phase Contrast Microscopy (PCM) for OSHA purposes. PCM methods accurately assess fiber exposure levels, but PCM can not differentiate between asbestos and non-asbestos fibers. Transmission Electron Microscopy (TEM) methods may be used to identify fibers, but may not be used to quantify air concentrations for occupational exposure.
Chemical Sampling Information. OSHA. Presents, in concise form, data on a large number of chemical substances that may be encountered in industrial hygiene investigations. Basic reference for industrial hygienists engaged in OSHA field activity.
Occupational Chemical Database. OSHA maintains this chemical database as a convenient reference for the occupational safety and health community. It compiles information from several government agencies and organizations. This database originally was developed by OSHA in cooperation with EPA.
OSHA has developed and validated methods for use by the Salt Lake Technical Center (SLTC) laboratory. The following method has been adopted by many laboratories for the analysis of chemical compounds. Exposures should be evaluated with standard total dust sampling techniques for comparison to the OSHA permissible exposure limits (PEL).
Polarized Light Microscopy of Asbestos. Method ID-191, (Revised December 1992). Describes the collection and analysis of asbestos bulk materials by light microscopy techniques including phase-polar illumination and central-stop dispersion microscopy.

Directory of Accredited Laboratories. National Voluntary Laboratory Accreditation Program (NVLAP), (2011, September 22). Includes online searchable directory. This accreditation is required for analyses being performed in compliance with AHERA regulations.
Controlling the exposure to asbestos can be done through engineering controls, administrative actions, and personal protective equipment (PPE). Engineering controls include such things as isolating the source and using ventilation systems. Administrative actions include limiting the workers exposure time and providing showers. Personal protective equipment include wearing the proper respiratory protection and clothing. The following resources contain information to help control asbestos exposures.
NIOSH Pocket Guide to Chemical Hazards. US Department of Health and Human Services (DHHS), National Institute for Occupational Safety and Health (NIOSH) Publication No. 2005-149, (2007, September). Provides a physical description, exposure limits, measurement method, personal protection and sanitation, first aid, respirator recommendations, exposure routes, symptoms, target organs, and cancer sites.
Occupational Health Guidelines for Chemical Hazards. US Department of Health and Human Services (DHHS), National Institute for Occupational Safety and Health (NIOSH) Publication No. 81-123, (1981, January). Contains information on identification, physical and chemical properties, health hazards, exposure limits, exposure sources and control methods, monitoring, personal hygiene, storage, spills and leaks, and personal protective equipment
Precautions to prevent exposure to asbestos in friction products (brakes and clutches).
Control of Asbestos Exposure During Brake Drum Service. US Department of Health and Human Services (DHHS), National Institute for Occupational Safety and Health (NIOSH) Publication No. 89-121, (1989, August). Presents recommendations for engineering controls and work practices to reduce exposure to asbestos during brake maintenance operations.
Asbestos Operations and Maintenance Program Online. Virginia Tech, Environmental, Health and Safety Services. Provides standard work practices and procedures including education and training, occupant awareness, building surveys, inspections and hazards, exposure monitoring, recordkeeping and management.
Applicability Determination Index (ADI). Environmental Protection Agency (EPA). Enables the user to query the database of National Emissions Standards for Hazardous Air Pollutants (NESHAP) which includes "regulatory interpretations". Enter keyword "Asbestos".
Protect Your Family. Environmental Protection Agency (EPA). Provides EPA guidance for home owners and their families.
