3. Engineering Controls:
The third most effective way to protect yourself from a hazard is by implementing an engineering control – in other words, a system that helps you isolate yourself from the danger.

Example :
Isolation – separating workers from the hazard by distance or the use of barriers ;
Enclosures – placing the material or process in a closed system (e.g., enclosed machines, booths, etc.) ;
Guarding and shielding – using guards around moving parts of machinery ;
Ventilation – using local exhaust or general dilution ventilation to remove or reduce airborne products ;
Mechanical lifting devices – using mechanical methods to lift or move objects instead of manual lifting ;
Guardrails – using guardrails to prevent a fall.
