Which method involves determining hazard potential and risk level for a new emitter and noting existing controls?

• A. OBSERVATIONS
• B. INTERVIEWS
• C. PREVIOUS SURVEYS
• D. EMITTER INVENTORY

Answer: (A)

Assessing hazard potential and risk level through direct observations is the best fit because it captures how the new emitter actually behaves in its environment and whether the existing controls are in place and functioning. Watching the emitter in operation reveals real-world conditions that could lead to exposure or release, such as emission rates, containment effectiveness, ventilation performance, and how workers interact with the equipment. This firsthand view lets you evaluate both what could go wrong (hazard potential) and how likely that event is given the current controls (risk level).

Interviews, previous surveys, and a simple emitter inventory each provide useful information, but they don’t give the same direct, current picture. Interviews depend on memory and perception, previous surveys may be outdated, and an inventory lists devices without assessing how hazardous they are or whether controls are adequate or functioning.
