Which set of steps describes performing a walk-through survey for hazard identification?

• A. Observe processes, review material data sheets, interview workers
• B. Observe processes only
• C. Review material data sheets only
• D. Interview workers only

Answer: (C)

In a walk-through survey aimed at hazard identification, the focus is on uncovering hazards tied to the materials present by checking documented hazard information for those substances. Material data sheets (SDS/MSDS) compile the chemical hazards, toxicity, flammability, reactivity, required controls, and PPE recommendations. By reviewing these sheets, you quickly identify which hazards exist, how workers could be exposed, and what controls should be in place, guiding you to prioritize areas for further inspection or intervention. While observing processes and talking with workers can enrich the assessment, the step set described centers on pulling the hazard details from the material data sheets to pin down the risks and necessary precautions.
