Description:In response to a request from the Oil, Chemical, and Atomic Workers International Union, an investigation was begun into possible health hazards associated with the use of a formaldehyde based additive at Unocal Corporation (SIC-2873), Kenai, Alaska. The company manufactured urea fertilizers at this site, producing about 1 million tons of urea and 1 million tons of ammonia per year. Environmental samples were collected to analyze for ammonia, total and respirable dust, formaldehyde (50000) vapors and formaldehyde on inhalable particulates during manufacturing operations. Formaldehyde concentrations in the air ranged from less than 0.006 to 2.2 parts per million (ppm). The highest concentrations were noted in the process of unloading a tanker which contained a formaldehyde based additive. At times, the formaldehyde levels as well as inhalable and total dust concentrations exceeded relevant limits. At times ammonia (7664417) concentrations also exceeded regulatory limits. Throat irritation was reported by 47% of the 21 employees interviewed. Nose irritation was noted by 43%, runny nose by 43%, and eye irritation by 33%. The authors conclude that workers were potentially exposed to formaldehyde and ammonia. The authors recommend that the exposures be reduced to more acceptable levels.
