Engineering Controls
If hazards cannot be eliminated or substituted, engineers can design systems that isolate workers from the hazard. Examples include guardrails, ventilation systems, and safety barriers.
Elimination Controls
The most effective control is to completely remove the hazard from the workplace. If a task or process can be redesigned to eliminate the hazard, this is the preferred method.
PPE Controls
As a last line of defense, PPE should be used to protect workers when hazards cannot be adequately controlled by other means. This includes hard hats, gloves, and safety goggles
Substitution Control
If elimination is not possible, consider substituting the hazard with something less dangerous. This could involve using safer materials or processes.
Administrative Controls
These involve changing the way work is done to reduce risk. This could include training, implementing safety procedures, or scheduling work to minimize exposure.
