What are the four steps of the occupational exposure assessment process used in BEA practice?

• A. Hazard identification, exposure assessment, dose-response assessment, and risk characterization.
• B. Exposure assessment, hazard analysis, dose-response assessment, and safety planning.
• C. Hazard identification, exposure monitoring, dose response, and incident reporting.
• D. Hazard identification, exposure assessment, risk communication, and program evaluation.

Answer: (A)

The four steps being tested are the sequence used to quantify and understand occupational risk: hazard identification, exposure assessment, dose–response assessment, and risk characterization. Start by identifying what hazards could cause adverse health effects in the workplace. Next, determine how workers are exposed to those hazards—their level, duration, and frequency. Then examine how exposure relates to health outcomes by looking at dose–response information and establishing relevant thresholds or reference values. Finally, integrate all this information to describe the overall risk, including uncertainties, and outline what actions or controls are warranted.

This approach aligns with BEA practice because it moves from recognizing potential dangers to measuring exposure, linking exposure to effects, and summarizing the risk to support decision-making. The other options mix in activities like planning, monitoring, incident reporting, risk communication, or program evaluation, which are important for broader safety management but are not the four foundational steps of the occupational exposure assessment itself.
