What activity should not be performed near combustible materials during hot work?

The activity that should not be performed near combustible materials during hot work is cutting with a welding torch. This is because using a welding torch generates extreme heat and sparks, which can ignite flammable materials in the vicinity. Hot work operations, including cutting, welding, or any other activity that produces a flame or spark, must be conducted in a controlled environment where combustible materials are either removed or adequately protected to prevent fire hazards.

In contrast, using protective barriers is a proactive measure meant to shield combustible materials from sparks and heat. Routine inspections ensure safe work practices and help identify potential hazards before they can cause incidents. Storing fire extinguishers is essential for immediate response should a fire occur, and they should always be available in areas where hot work is conducted. Each of these practices contributes to a safer work environment, particularly when compared to the risks posed by cutting with a welding torch among combustible materials.
