Respiratory Protection

One of the principal routes by which chemicals can enter the body is through inhalation. If an individual is exposed to an excessive airborne concentration of a chemical over a long period of time, undesirable health effects can result.

OSHA has set maximum exposure standards for many airborne toxic materials. The Office of Environmental Health and Safety (EHS) can assist in determining whether a worker’s exposure to chemicals and/or particulates with which he or she works exceeds these standards. If the permissible exposure limit is exceeded, the exposure must be reduced to acceptable levels through the use of engineering and/or administrative controls.
