Welding Fume Exposures and Controls: Do We Know Enough?
Welding in the workplace can present significant health hazards unless the potential (and actual) exposures to welding fumes are properly identified, evaluated, and controlled. The sheer numbers of the types of exposure, both acute and chronic, justify a thorough review of the possibilities, the hazards of exposure, and potential controls. This article, while not covering all of these possibilities, may at least prompt environmental, health, and safety professionals to consider these exposures, evaluate actual exposures, and implement appropriate protective measures.
