Sundström SR77 escape hood
for smoke and chemicals
Updated: 02 Jan 2005
Description:
Emergency smoke/chemical escape hood incorporated with a half face respirator.
The respirator is normally fitted with a special gas/particle filter, providing short-term protection against smoke, carbon monoxide, acrolein, hydrogen chloride, hydrogen cyanide and other toxic gases and particles that may be present in a fire (such as hazardous fumes released from burning plastic materials).
The respirator is normally fitted with a special gas/particle filter, providing short-term protection against smoke, carbon monoxide, acrolein, hydrogen chloride, hydrogen cyanide and other toxic gases and particles that may be present in a fire (such as hazardous fumes released from burning plastic materials).
The hood material is heat and chemical resistant.
Usage:
The SR77 is a filter respirator combined with a protective hood with a visor. It is used for rapid (15 minutes) self-rescue.
Used against particles, dust, smoke, fume, bacteria, viruses, biological warfare agents, and a wide range of organic, inorganic and acid gases and ammonia.
Used against particles, dust, smoke, fume, bacteria, viruses, biological warfare agents, and a wide range of organic, inorganic and acid gases and ammonia.
Examples FOR ESCAPE ONLY: Sarin, nerve gas, mustard gas, cyanogen, phosgene, radioactive dust, toxic particles, aerosols, tear gas, bacteria, viruses, anthrax, smallpox etc. — Also provides protection against industrial gases such as ammonia, hydrogen cyanide, acid gases, chlorine, sulfur dioxide, hydrogen chloride and many more.
The device can be put on quickly and simply in a single action, without any adjustment.
Product names:
SR77S (for stationary storage)
SR77M (portable)
