Which statement about hot work in chemical facilities is true?

• A. Hot work is any activity generating heat or sparks
• B. Hot work never requires safety checks
• C. Hot work can proceed without supervision
• D. Hot work only means welding and nothing else

Answer: (A)

Hot work means any task that generates heat, sparks, or flames that could ignite flammable vapors or dust in a chemical facility. Because of the ignition risk, such work is controlled with a formal hot work permit, a fire watch, and proper area preparation to remove ignition sources. This broad definition—encompassing activities that produce heat or sparks, not just a single activity—explains why it’s true. It covers welding, cutting, grinding, brazing, soldering, and similar tasks, not only welding. The other statements falsely imply no safety checks, no supervision, or a narrow scope, which isn’t how hot work is managed in plant safety programs.
