Sundström SR77-3 Escape Mask

Escape mask SR 77-3 is a half mask combined with a hood for use during evacuation in the event of fire and chemical accidents. The hood is based on Sundström's silicon half mask, mounted in a hood made of flame-resistant and chemical-resistant material. Hoods are vacuum-packed in an aluminum bag. The hood can be donned quickly and easily without prior adjustment. The hood is available in two sizes and fits most adults. The hood is equipped with gas filter SR 331-2 ABEK1-CO and particle filter SR 510 P3. The filter combination protects against carbon monoxide and other toxic gases and particles that can form in the event of a fire, and also against the following types of gases: A1, organic gases and vapors, e.g., solvents with a boiling point above +65 °C. B1, inorganic gases and vapors, such as chlorine, hydrogen sulfide, and hydrogen cyanide. E1, acidic gases and vapors such as sulfur dioxide and hydrogen fluoride. K1, ammonia and certain amines, e.g., ethylenediamine. Filter 331-2 cannot be purchased separately, and the entire mask must be discarded after use.
