Personal Gas Warning Systems.

NIOSH 1973 Jan:21 pages
In response to a request from NIOSH, an extensive literature search was conducted to determine the substantive literature available on the subject of personal gas warning systems. It was decided that such a system should be compact, fully portable, and able to give warning in time for a person to escape injury. Not only was a search made of the open literature, but sources such as manufacturers' catalogues and advertisements were also searched and contact was made with six manufacturers and three organizations whose prime interests were in this field. The results indicated that very little work has been done on the development of such devices. Work was reported concerning detection of carbon-monoxide (630080) (CO), hydrazine (302012), and oxygen (7782447) levels. The total number of devices either currently available or in the experimental stage include four CO badges, one CO indicator card, one colorimetric dosimeter badge for hydrazine and other volatiles, and a cigar shaped oxygen detector. No success was achieved in finding statistics on industrial injuries caused by exposures to toxic or otherwise harmful gases. A description was offered of the personal gas detectors which were commercially available, including the names of the manufacturers and distributors. A list of gases most commonly found at industrial work sites was included along with their threshold limit values. The physiological effects of noxious gases and vapors were briefly considered.
