Do you know when a respirator should be used?
Workers should use respirators for protection from contaminants in the air only if other
hazard control methods are not practical or possible under the circumstances. Respirators
should not be the first choice for respiratory protection in workplaces.
They should only be used:
1.when following the "hierarchy of control" is not possible (elimination, substitution,
engineering or administrative controls)
2.while engineering controls are being installed or repaired
3.when emergencies or other temporary situations arise (e.g., maintenance operations)
