Which permit is mandatory for hot work in confined spaces?

• A. Entry Permit
• B. Safety Permit
• C. Hot Work Permit
• D. Confined Space Permit

Answer: (C)

Hot work in a confined space creates a high risk of fire or explosion because sparks, flames, or heated metal can ignite flammable vapors in a restricted area, and ventilation may be limited. The permit dedicated to hot work serves as the authorization that confirms the necessary controls are in place before any flame- or spark-producing activity begins. It captures the specifics of the work, ensures ignition sources are controlled or isolated, flammable materials are removed or protected, ventilation is adequate, gas tests are completed, and a fire watch or fire suppression plan is in place. This focused documentation is what makes it the correct choice. An entry permit covers safe entry into a space but doesn’t address the hazards specific to hot work. A general safety permit is too broad for the precise controls required for hot work in a confined space. A confined space permit addresses entry and overall confined-space hazards, not the specialized fire-prevention measures for performing hot work. In some programs, a combined permit might be used, but when identifying the specific permit required for hot work in a confined space, the hot work permit is the appropriate one.
