Chemicals in the mining industry pose a range of hazards to exposed miners, from mild health effects to death. Some chemicals cause or contribute to chronic health problems, such as heart or kidney disease or cancer. Others cause acute injuries or illnesses such as dermatitis, burns, and poisonings. Some chemicals pose hazards by contributing to fires and explosions. The toll of chemically-related injuries and illnesses in the mining industry can be obscured by years of latency between an exposure to a chemical and the onset of an illness.

MSHA's Hazard Communication Standard, which we have called HazCom, expresses two safety and health principles: miners have a right to know about the chemical hazards where they work and you have a responsibility to know about the chemical hazards at your mine. HazCom requires you to inform miners about chemical hazards.

This single source page will provide you with information and resources regarding HazCom. Please check back for updates.

    NIOSH's HazCom Writer provides individuals responsible for writing a MSHA HazCom written program with software to aid in writing their HazCom program and for identifying hazardous chemicals on site. MSHA�s new HazCom rule (30 CFR Part 47) requires all mines to determine which chemicals are hazardous, write a Hazard Communication Program, label all containers containing hazardous chemicals, keep MSDs' s for all hazardous chemicals, provide HazCom training to employees, and to make the HazCom information available to employees.
