Introduction
Personal Protective Equipment (PPE) is the last line of defense against chemical hazards. Proper selection, use, and maintenance of PPE is essential for worker safety in chemical handling operations.
Hierarchy of Controls
Control Priorities
- Elimination: Remove the hazard
- Substitution: Replace with safer alternative
- Engineering Controls: Isolate people from hazard
- Administrative Controls: Change work practices
- PPE: Protect worker with equipment
PPE Role
- Residual risk management
- Emergency situations
- Maintenance operations
- Supplement to other controls
