Dust respirators in mines and tunnels.
Handbook for dust control in mining. Pittsburgh, PA: National Institute for Occupational Safety and Health, 2003 Jun; :119-127
In this chapter: MSHA regulations for coal mines; MSHA regulations for metal/nonmetal mines; OSHA regulations for tunnel construction; types of respirators used in mines and tunnels; filter materials and filter efficiencies; donning, seal checking, and maintenance; filter service life and respirator information resources. In many cases, engineering controls are not adequate to achieve satisfactory dust levels, so respirators must be used. This chapter explains the Federal regulations governing the use of dust respirators in mines and tunnels and describes the most common dust respirators used. Filter materials and filter efficiencies for respirators are discussed. This chapter also gives some guidelines for respirator use and recommends sources for more dust respirator information. Respirator effectiveness in reducing dust exposure usually exceeds the effectiveness of most engineering control methods.
