Which term refers to documentation provided by the manufacturer detailing how to safely operate equipment?

• A. Hazard Analysis
• B. Impedance
• C. Permit
• D. Operating Instructions

Answer: (D)

Operating instructions are the manufacturer-provided guidelines that tell you how to use equipment safely. This document covers how to start and stop the system, how to operate the controls, what safety warnings and precautions to follow, and what to do in abnormal or fault conditions. It may also outline maintenance intervals, required PPE, and specific procedures for handling the particular refrigerant and components involved. In the context of flammable-refrigerant systems, following these instructions is essential to prevent ignition, leaks, or other hazards and to ensure the equipment is used as designed.

Hazard analysis focuses on identifying hazards and mitigation strategies, not on how to operate the equipment day to day. Impedance is a technical term related to electrical resistance, not documentation. A permit is a work authorization, not the operating manual.
