Abstract
Walk through surveys of facilities handling hydrazine (302012) were conducted. Eight facilities were surveyed. These included installations where hydrazines were used as propellants, hydrazine production sites, sites where hydrazine was used as an aircraft emergency power unit fuel, and sites where hydrazine was used in boiler water treatment. At all facilities, employers and employees were aware of the need to avoid exposure and had developed hydrazine handling systems, work practices, and personal protective equipment programs to minimize the risk of exposure. Hydrazine production activities generated time weighted average (TWA) exposures that were generally well below 0.1 part per million, primarily because the production processes involved closed systems. Using hydrazines as propellants involved potential exposures while loading or unloading spacecraft and in related propellant transfer operations, and while testing spacecraft components that utilized hydrazines. The authors conclude that TWA exposures to hydrazine compounds are relatively low. The number of exposed workers is also small. Current manufacturing methods are relatively new as is large scale propellant and emergency power unit usage. The accumulated person/years are relatively low, and it is unlikely that suitable cohorts exist for retrospective exposure studies.
