Which item is NOT a component of Observations and Interview?

• A. Visual clues
• B. Speaking to personnel
• C. Potential hazardous
• D. Instrument readings

Answer: (D)

Observations and interviews rely on what you can directly see and what people tell you. You’re gathering qualitative information: visual clues like spillages, clutter, or unsafe practices; conversations with personnel about procedures, training, and recent incidents; and identifying potential hazards by assessing the environment and work practices. Instrument readings, however, come from tools that measure and quantify conditions—gas concentrations, noise levels, temperatures, pressures, etc.—and those require specific instruments rather than relying on observation or verbal input. So instrument readings don’t fit into the Observations and Interview component; they belong to a measurement-based part of the assessment.
