MSHA Air Sampling Programs for Carcinogens such as Asbestos
Read how the U.S. Department of Labor (DOL) and the Mine Safety and Health Administration (MSHA) determine the sample criteria for the air sampling programs designed to assist miners, who are routinely exposed to carcinogens, including asbestos.
Preliminary walk-around observations and direct-read area sampling data can be used to select miners for personal monitoring.
In an ideal situation, each potentially exposed miner would be individually sampled.
It is not necessary, however, to sample all miners on a mine property in order to evaluate occupational exposures.
