- Wood Dust
There are a number of ways to check the workplace for airborne wood dust. However, the only way to be certain of excessive exposure levels is to monitor the air for wood dust and compare the results with the relevant occupational exposure levels. The following links provide information about evaluating the level of wood dust in the workplace.
- Chemical Sampling Information. OSHA. Includes recommended exposure limits and sampling and analysis methods.
- 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.
Occupational Exposure Levels
Several organizations have set standards or given recommendations for wood dust exposure. These include OSHA, NIOSH, and the American Conference of Governmental Industrial Hygienists (ACGIH).
|Organization||OEL||8 Hour TWA||Basis|
|OSHA||Permissible Exposure Limit Particulate Not Otherwise Regulated (PNOR)||15 mg/m 3 total 5 mg/m 3 Respirable||Throat, skin, eye irritation, upper respiratory problems|
|NIOSH||Recommended Exposure Limit||1 mg/m 3 total||Pulmonary Function, Carcinogen|
|TLV ACGIH 2007||Western Red Cedar||0.5 mg/m 3||Asthma|
|ACIGH 2007||All other species||1 mg/m 3||Pulmonary Function|
Analytical MethodsNational Institute for Occupational Safety and Health (NIOSH)
- NIOSH Manual of Analytical Methods (NMAM). NMAM is a collection of methods for sampling and analysis of contaminants in
workplace air, and in the blood and urine of workers who are occupationally exposed. NMAM also includes chapters on quality assurance, sampling, portable instrumentation, etc.
- Particulates Not Otherwise Regulated, Total. Method 0500, Issue 2, (August 15, 1994).
