What does a worker exposure survey do?

• A. Where the potential to exceed the limits exists, worker exposures shall be evaluated by direct measurements with noise dosimeters, or indirectly with noise exposure calculations
• B. It measures only the room temperature
• C. It records the color of employee uniforms
• D. It measures the color of PPE

Answer: (A)

A worker exposure survey is about determining whether employees are at risk of exceeding occupational exposure limits by collecting data on actual exposures. It looks for situations where limits might be exceeded and uses direct measurements, such as noise dosimeters that track sound levels over a shift, or indirect methods like calculations based on task duration, emission rates, ventilation, and worker activities when measurement isn’t feasible. The purpose is to quantify exposures so that appropriate controls—engineering changes, administrative actions, or PPE—can be chosen. The other ideas don’t fit this purpose. Measuring room temperature, recording uniform colors, or noting PPE colors doesn’t provide data about workers’ exposure to hazards; those items don’t quantify or assess exposure risk.
