Ventilation

Permissible Exposure Limits (PELs), established by the Washington Department of Safety and Health (DOSH), shall not be exceeded (see Appendix B). Eight-hour and short-term permissible exposure limits to many chemicals have been set by DOSH to prevent adverse health effects in workers. Local exhaust ventilation systems may be required in order to reduce exposure levels to these acceptable limits. For assistance in measuring chemical exposures and in comparing them to the appropriate limits, please contact Environmental Health & Safety at 335-3041.
