Nitrogen tetroxide

CAS RN: 10544-72-6

Protective Equipment / Clothing

It is essential to provide space workers handling /nitrogen tetroxide/ whole body protection ... not only to the respiratory system, but the skin as well ... A new method /is described/ for powering a whole body protective garment to assure the safety of ground servicing crews ... The new technology employs the storage of the supply air as a supercritical gas ... This supercritical air (and oxygen) technology is suggested for microgravity applications in life support such as the Extravehicular Mobility Unit.
Vendor recommendations concerning the protective qualities of materials are as follows: Butyl, polyethylene, chlorinated polyethylene and CR-39 received excellent or good ratings from less than three vendors (no fair or poor ratings), and good or fair ratings, with good ratings predominating, from several vendors; Polyvinyl chloride received fair or poor ratings from three or more vendors; Chlorobutyl received excellent or good ratings from three or more vendors.
Recommendations for respirator selection. Max concn for use: 20 ppm. Respirator Class(es): Any supplied-air respirator operated in a continuous flow mode. Eye protection needed. Any self-contained breathing apparatus with a full facepiece. Any supplied-air respirator with a full facepiece. /Nitrogen dioxide/
Recommendations for respirator selection. Condition: Emergency or planned entry into unknown concn or IDLH conditions: Respirator Class(es): Any self-contained breathing apparatus that has a full facepiece and is operated in a pressure-demand or other positive-pressure mode. Any supplied-air respirator that has a full facepiece and is operated in a pressure-demand or other positive-pressure mode in combination with an auxiliary self-contained breathing apparatus operated in pressure-demand or other positive-pressure mode. /Nitrogen dioxide/
Recommendations for respirator selection. Condition: Escape from suddenly occurring respiratory hazards: Respirator Class(es): Any air-purifying, full-facepiece respirator (gas mask) with a chin-style, front- or back-mounted canister providing protection against the compound of concern. Only nonoxidizable sorbents are allowed (not charcoal). Any appropriate escape-type, self-contained breathing apparatus. /Nitrogen dioxide/
