The demand for escape masks and life safety equipment that are with the capacity of protecting untrained folks from chemical, biological, radiological, and nuclear inhalants was increasing since 9/11 among civilians over the world. This demand was furthered by the anthrax attacks around the US.


Companies which saw the marketing potential of the raising concern and demand for personal protection started to sell escape safety masks to the general public. some governments around the world understood the performance of these safety products in response to terror attacks and their importance in times of war.

The brand new requirements for air-purifying escape respirator certification were developed utilizing the concept development process and are responsive to public comments The National Institute for Occupational Safety and Health (NIOSH) received during some public meetings, numerous stakeholder meetings, and to the NIOSH docket. You can find out more has been assimilated and has been put into additional requirements the agency determined are essential to establish the quality, safety and effectiveness of any respirator used as protection against hazardous atmospheres. This standard offers a universal benchmark by which users can assess performance of the products.

A smoke hood is really a life safety equipment similar in concept to other safety products as gas mask. A translucent airtight bag seals round the head of the wearer while an air conditioning filter held in the mouth connects to the outside atmosphere and is used to breathe. Smoke hoods are intended to protect victims of fire from the effects of smoke inhalation.

Smoke hoods present on aircraft, also called Protective Breathing Equipment, typically generate oxygen for from 30 seconds to a quarter-hour. The oxygen is kept in a closed circuit, usually because of a good neck seal. A scrubber system could be present to reduce the levels of skin tightening and, and is breathable for around 20 minutes. When the oxygen supply ends, the hood will start deflating and should be removed in order to avoid suffocation.

High quality smoke hoods are usually made of heat resistant material and will withstand relatively high temperatures. The most important section of a smoke hood may be the filter that delivers protection from the toxic byproducts of combustion. Practically all smoke hood designs utilize some type of activated charcoal filter and particulate filter to screen out corrosive fumes like ammonia and chlorine, in addition to acid gases like hydrogen chloride and hydrogen sulfide. The defining characteristic of a highly effective smoke hood is the capability to convert deadly carbon monoxide to relatively harmless carbon dioxide through a catalytic process.
