Evaluation of Exposures to Chemical and Physical Agents in Radiator Repair Shops

Abstract

The Nova Scotia Department of Labour conducted a survey in the summer of 1988 on the occupational health and hygiene aspects of the radiator repair industry. This survey was the first of a series of projects aimed at proactively reviewing industries which may pose health and/or safety risks. In all, 19 shops were surveyed. Most of the shops were small firms, usually with three or four employees. There were no women employed in the actual radiator repair process. The survey examined lead levels, as well as exposures to gasoline, silica, corrosives, and heat. The results indicated that both airborne and blood-lead levels were generally within the regulatory standards in Nova Scotia. However, the airborne lead levels were often in excess of the U.S. Occupational Safety and Health Administration standards. There was no significant relationship found between blood-lead levels and either smoking habits or ventilation design. The survey did indicate that exposures to gasoline, silica, corrosives, and heat could have adverse health effects. Based on the survey results, the Department of Labour concluded that industrywide, mandatory working procedures are not required for radiator repair shops. Instead, detailed information and guidance were given to all shop owners.
