Question

question 2 of 3
at what point in the hierarchy of hazard control should ppe be selected and implemented in the work environment?
if you cant substitute a safer substance for a chemical hazard
if the engineering controls dont protect workers completely from a chemical hazard
if administrative protection doesnt protect workers completely from a chemical hazard

Explanation:

In the hierarchy of hazard control, PPE (Personal Protective Equipment) is the last - line of defense. Engineering controls (like ventilation systems) and administrative controls (like work - hour restrictions) are preferred first. Only when these higher - level controls are insufficient should PPE be used.

Answer:

If the engineering controls don't protect workers completely from a chemical hazard
