Acting on a request from an employee representative concerning the possibility of a health hazard due to welding fumes from arc welding on zinc plated or painted steel in confined areas, a Health Hazard Evaluation survey was conducted by NIOSH on January 5, 1977, at the Kaiser Marine facility, for the construction of seagoing vessels (SIC-3731), in Vallejo, California. The alleged health hazard involved welding fumes generated while welders worked inside the columns of a high oil exploratory drilling rig, where welding on paint coated galvanized steel was supposedly carried out without adequate ventilation and safeguards. Based upon the work practices observed and the conditions at the job site at the time of the NIOSH investigation, it was determined that welding fumes probably do not represent a health hazard to the approximately 11 potentially affected machinists. This determination is based upon the best judgement of the NIOSH investigator since the welding job which precipitated the request was already completed and could not be duplicated. None of the mechanics employed at the time of the survey presented any signs or symptoms of welding fume exposure.
