Ignition hazards during deicing are controlled by using approved fluids, keeping ignition sources away, and following established procedures. Fluids that are approved for deicing have known flash points and compatibility with aircraft materials, which helps prevent vapors from igniting and reduces the risk of chemical reactions. Keeping ignition sources out of the deicing area—such as sparks, hot surfaces, and energized equipment—prevents potential ignition of any flammable vapors that may be present on or around the aircraft. Following prescribed procedures ensures the correct fluid type and application, coverage, time windows, and safe sequence for engine shutdown and restart, all of which minimize exposure to flammable vapors and ensure proper safety controls. Starting engines early or using non-approved fluids would increase ignition risk and violate safety protocols, while disregarding procedures eliminates the safety checks that protect everyone on the ramp.
