Usage:
The hood is equipped with gas filter SR 331-2, ABEK1-CO and particulate filter SR 510, P3, and provides short-term protection against carbon monoxide and other toxic gases and particles that may be emitted in a fire or in a chemical emission accident.
Product names:
SR77-2 S (for stationary storage)
SR77-2 M (portable escape hood)
SR77-2 M (portable escape hood)
Face piece:
The hood is available in two sizes and fits most adults and teenagers.
Hood:
The hood is made of flame-resistant material.
Visor:
Scratch-resistant, anti-mist, polycarbonate
Fitting:
The hood can be put on quickly and simply without prior adjustment.
Temperature:
-30°C to +70°C (-22F to +158F)
Filter:
The hood is equipped with gas filter SR 331-2, ABEK1-CO and particulate filter SR 510, P3:
A1 organic gases and vapours, such as solvents, with boiling points above 65oC.
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.
Weight:
590 g (21 oz)
Size of pack:
120 x 120 x 170 mm (4.7" x 4.7" x 6.7")
Storage:
