Respiratory Protection


There are several ways to protect against exposure to airborne contaminants. The most effective are engineering and administrative controls. (Engineering controls can include measures such as increasing ventilation or installing a fume hood; administrative controls involve changes in work procedures.) The law requires that these controls be considered before employees are issued respirators. If engineering and administrative controls are infeasible, respirators can be assigned.
