MODEL B570 contains a specially blended Sodium Chloride based dry powder extinguishing agent.
Heat from the fire causes it to cake and form a crust excluding air and dissipating heat from burning
metal. Metal fires involving magnesium, sodium, potassium and sodium-potassium alloys can be
successfully extinguished with this extinguisher. There is data showing that zirconium, uranium,
titanium, and powdered aluminum fires can be controlled and extinguished with this unique
extinguisher.
