What is the purpose of an exposure assessment?

• A. To determine whether workers’ exposures to hazards exceed permissible levels and to guide controls.
• B. To measure structural vibration.
• C. To record equipment warranty periods.
• D. To schedule annual training.

Answer: (A)

Exposure assessment aims to determine whether workers’ exposures to hazards are within safe limits and to inform what controls are needed. By measuring or estimating how much of a hazard workers encounter and comparing it to established permissible exposure limits, you can decide on appropriate actions—engineering controls, administrative changes, or personal protective equipment—to reduce risk. This isn’t about measuring structural vibration, recording equipment warranties, or scheduling training, which fall outside assessing worker hazard exposure.
