Which activity requires a permit according to the material?

• A. Welding or hot work
• B. Use of a fire extinguisher
• C. Loading docks
• D. Use of any machinery

Answer: (A)

Activities that can ignite a fire are controlled with a formal permit system, so work like welding or other hot work requires a permit before it starts. This permit is a documented authorization that ensures critical fire-safety measures are in place: clearing and shielding combustibles, having a fire watch, available fire extinguishers, proper ventilation, and a defined time window and site responsibilities. The purpose is to prevent fires from sparks and heat generated during welding or cutting.

The other items don’t inherently need this kind of permit. Using a fire extinguisher is a safety action done when needed and doesn’t require prior authorization, though proper training and readiness are essential. Loading docks and general machinery use involve standard safety procedures and equipment checks, not the hot work permit process, though they may involve their own specific protocols.
