Which hierarchy of controls level involves replacing a hazardous material with a less hazardous one?
Answer: Substitution
Substitution replaces a hazardous material or process with a less hazardous alternative.
How do engineering controls differ from administrative controls?
Answer: Engineering physically changes the workplace; administrative changes how people work
Engineering controls physically modify the environment; administrative controls change work practices.
What is a risk assessment matrix used for?
Answer: Evaluating and prioritizing hazards based on likelihood and severity
A risk matrix combines likelihood and severity to prioritize hazard controls.
Why is PPE the least effective control level?
Answer: PPE depends on correct selection, fit, use, and maintenance while the hazard still exists
PPE relies entirely on correct use while the hazard remains at full strength.
What is residual risk in hazard control?
Answer: The risk remaining after all reasonably practicable controls are implemented
Residual risk is the level remaining after all practicable controls have been applied.
How should a supervisor determine the appropriate control level?
Answer: Apply the hierarchy from the top, implementing the highest feasible level
Work through the hierarchy from top down selecting the highest feasible level.
