Which term defines the process of assessing potential hazards to reduce risk?

• A. Impedance
• B. Hazard Analysis
• C. Nominal Voltage
• D. Monitoring

Answer: (B)

Assessing potential hazards to reduce risk is hazard analysis. This is the systematic process of identifying what could go wrong in a system or operation, judging how likely those hazards are and how severe their consequences could be, and then applying controls to prevent or mitigate them. In flammable-refrigerant systems, hazard analysis helps you spot risks like leaks, vapor clouds, ignition sources, and overpressure, so you can implement ventilation, leak detection, proper electrical safety, and safe piping layouts to minimize both likelihood and impact. The other terms don’t fit this purpose: impedance is electrical opposition to current, nominal voltage is simply a rated voltage, and monitoring is observing conditions over time, which supports safety but is not the process of analyzing hazards to reduce risk.
