PSD Aerial Ignition Demonstrated & Explained: Plastic Sphere Dispenser

Filmed at the Hayden Pass Fire Helibase: Garden Valley Helitack squad leader D.W. Cook and crew members demonstrate how PSD, also known as ping pong balls, really work. PSD is a critical aerial ignition tool utilized by firefighters to allow back burns in sometimes impossible to reach areas of the forest so that fire managers are able connect fire containment lines. PSD is designed with Potassium permanganate, a purplish colored crystalline solid that is noncombustible but will accelerate the burning of combustible material. The PSD is injected with ethylene glycol to create a chemical reaction before being dropped from the helicopter and igniting seconds after hitting the ground.
