Exhalation valve (2) The SR 77-3 Escape Hood is a filtering respiratory protective device combined with a hood for self rescue in the event of a fire or a chemical emission accident. The hood is based on a Sundström silicone half mask, which is mounted in a hood made of flame-resistant material. The hoods are vacuum-packed in aluminum bags. The hood can be put on quickly and simply without prior adjustment. The hood is available in two sizes and fits most adults and teenagers. The hood is equipped with gas filter SR 331-2, ABEK1-CO and particle filter SR 510, P3 , and provides short- time protection against carbon monoxide and other toxic gases and particles that may be emitted in a fire or in a chemical emission accident. A1 , organic gases and vapours, such as solvents, with boiling points above 65 °C. B1 , inorganic gases and vapours, such as chlorine, hydrogen sulphide and hydrogen cyanide. E1 , acidic gases and vapours such as sulphur dioxide and hydrogen fluoride. K1 , ammonia and certain amines, such as ethylene diamine. The SR 77-3 S is approved only for stationary storage. The SR 77-3 M is approved also as portable escape hood and is delivered in a contingency bag made of nylon and designed for mounting on a belt.
