Which term is described as a description of performance derived from testing or evaluation that guides appropriate selection, installation, and use of equipment that is not listed?

• A. Primary safety control
• B. Flame effect plan
• C. Rated
• D. Safety Shutdown (Lockout)

Answer: (A)

This item tests how a performance description derived from testing is used to guide the safe selection, installation, and use of equipment that isn’t listed. That description is called a rating. A rating communicates the limits and conditions under which non-listed equipment has been evaluated to perform safely—things like allowable loads, temperatures, pressures, or flame characteristics. By providing these tested performance criteria, a rating helps you decide whether the unlisted gear can be used in a system and what safeguards or operating parameters must be observed.

The other terms describe safety functions or planning documents rather than performance criteria for non-listed gear. A primary safety control is about a device that automatically limits or stops unsafe operation. A flame effect plan covers how effects are designed and executed. Safety Shutdown (Lockout) refers to procedures and systems used to isolate energy for safety.
