Health Hazard Evaluation Determination Report No. HHE-78-087-573, Melroe Division of Clark Equipment Co., Gwinner, North Dakota

摘要

Breathing zone and general area samples were taken for polynuclear-aromatic-hydrocarbons (1330207), iron-oxide (1309371), manganese (7439965), copper (7440508), aluminum (7429905), zinc (7440666), oil decomposition products, xylene (1330207) oil-mists and bulk samples of cutting oils were analyzed for nitrosamines and nitrosamine forming compounds at Melroe Division of Clark Equipment Co. (SIC-3523), in Gwinner, North Dakota on July 20 and 21, 1978. An evaluation request came from an authorized representative of more than 100 affected employees. Samples for all chemicals were below the evaluation criteria. The authors conclude that no health hazard exists at this facility. They recommend that currently used cutting oils should be substituted with oils that do not contain polynuclear aromatic hydrocarbons and that oil coated parts should be degreased before welding.
