• B. Hot work permit system
• C. Mandatory audible warning only
• D. Use of fire extinguisher after

Answer: (B)

A formal hot work permit system is required to authorize any hot work in a chemical processing facility. This approach ensures that every potential ignition source is controlled before work starts. The permit prompts a hazard assessment and requires safeguards such as removing or protecting flammable materials, isolating the work area, controlling ignition sources, and performing gas tests if vapors could be present. A fire watch is assigned for the duration of the work (and for a period afterward), and appropriate fire-extinguishing equipment is ready. Only after these checks is the hot work allowed to proceed, and the permit stays in effect for the task’s duration. This proactive control is essential to prevent fires, rather than relying on warnings or waiting to respond after a fire starts.
