Treat hot air as a fire source
Heat guns can ignite dust, paper, insulation, paint debris, vapors, and nearby surfaces.
Clear the bench, keep a nonflammable resting area ready, and do not aim heat at anything you cannot see clearly.
Cool-down is part of the job
The nozzle and nearby surfaces remain hot after use.
Set the tool on a safe stand and keep it away from cords, packaging, cloth, and curious hands while cooling.
