Which statement about hot work permits is true?

• A. They require no authorization.
• B. They require explicit authorization and documented controls.
• C. They apply only to maintenance tasks.
• D. They are optional in well-trained teams.

Answer: (B)

Hot work permits exist to control ignition risks whenever heat, flame, or sparks are involved. They require explicit authorization before any hot work begins and a documented set of controls to prevent fires. The permit records what work is being done, where, when, and for how long, along with the hazards and the exact safeguards required (such as removing or shielding combustibles, having a fire watch, appropriate fire extinguishers, gas or vapor checks, isolation of energy sources, and adequate ventilation). The permit is only valid for the defined period and can be halted if conditions change.

This is why the statement is true: explicit authorization and documented controls are essential to safely manage hot work. The other ideas aren’t correct because hot work safety isn’t optional or limited to maintenance, and it isn’t something a well-trained team can skip.
