C. A machine guarding device
D. A ventilation system
E. All of the above
The answer is E. All of the above.
An engineering control is a device or system that removes a hazard or reduces the risk of exposure to a hazard. Engineering controls are used to protect workers by controlling the exposure to a hazard at the source. Forcing functions are a type of engineering control.
Forcing functions are physical barriers that prevent workers from coming into contact with a hazard. Forcing functions can be found in a variety of workplace settings, such as in manufacturing plants where there are moving parts on machinery.
Safety signs and symbols are another type of engineering control. They are used to warn workers of potential hazards and to provide information on how to safely work in the area.
Machine guarding devices are another type of engineering control. They are used to protect workers from being injured by moving parts on machinery.
Ventilation systems are another type of engineering control. They are used to remove hazardous substances from the air and to keep the air in a work area fresh and free of contaminants.
