NIOSH 1992 May:24 pages
In response to a request from an authorized employee representative at the Mueller Company (SIC-3362), Decatur, Illinois, an evaluation was undertaken of formaldehyde (50000) exposures to employees in the core making room and pour deck areas. The Mueller Company is a grey iron and brass foundry producing valves for water and gas distribution service. Formaldehyde levels of 0.32 to 0.65 parts per million were recorded. Three of seven readings exceeded the OSHA permissible exposure limit of 1 part per million. Respirable dust sampling measured 4.34mg/m3 in the breathing zone of the muller operator and 1.46mg/m3 at a location 10 feet from the front of the muller at breathing zone height. Silica (14808607) content in these samples was 60.2% and 50.0%, respectively. Exposure to cadmium (7440439), lead (7439921), and zinc (7440666) on the pour deck exceeded one or more of the evaluation criteria; appropriate respiratory protection was used by workers in this area. Symptoms reported by the workers included headache, sinus pain, nausea, and eye irritation. Silicosis was verified in one worker. Formaldehyde related dermatitis was diagnosed in another. The authors conclude that there was a hazard from exposures to formaldehyde and silica. The authors recommend specific measures to reduce these hazardous exposures.
