Hydrazine: Usage and Exposure in the Electric Power Industry.
The likelihood of employee exposure to hydrazine (302012), dimethylhydrazines (DMH), and nitrosamines was studied in the coal fired electric power generation industry. Included in the study were a literature search, contacts with supplies, contacts with Environmental Protection Agency scientists, and two industrial hygiene surveys at representative power facilities. At each of these facilities hydrazine-hydrate (7803578) was added to the boiler water system to act as an oxygen scavenger. The technician adding the hydrazine at one facility wore a face shield, a rubber apron and rubber gloves. At the second facility the employee wore rubber gloves and goggles. None of the employees at either site had experienced any problems of irritation from hydrazine exposure. Even the distinctive odor of hydrazine was not noticeable. The findings suggest that employee exposures to hydrazine were well below federal standards and that exposures to DMH and nitrosamines appeared unlikely.
