Mine safety: Air sample tests for asbestos and other carcinogens
Read the U.S. Department of Labor (DOL) and the Mine Safety and Health Administration (MSHA) report about the contaminants they sample to determine the risks to miners. Those workers are routinely exposed to carcinogens such as asbestos.
The following sections describe the most common types of contaminants sampled, the usual sources of these contaminants, some of the health effects encountered with each, and give suggestions for evaluating the hazard and designing a sampling strategy.
