  • Description

    Access the latest requirements for minimizing fire risks and safeguarding personnel in mines and metal mineral processing facilities.

    NFPA® 122, Standard for Fire Prevention and Control in Metal/Nonmetal Mining and Metal Mineral Processing Facilities, addresses the protection of diesel-powered equipment and storage and handling of flammable and combustible liquids at these specialized sites. The updated 2023 edition reflects the most current industry knowledge and practices.

    Important changes include:

    • Addition of a new Chapter 14, Conveyors, which includes requirements for conveyors to align with NFPA 120, Standard for Fire Prevention and Control in Coal Mines
    • New Chapter 15, Ventilation in Underground Mines, which includes safety requirements for ventilation to reduce combustible gas concentrations and align with NFPA 120
    • Added Chapter 16, Emergency Preparedness and Response, which includes requirements for emergency preparedness and response plans
    • Revisions made to reorganize and update the requirements in Chapter 13, including new annex material added to strengthen fire protection guidance that relies heavily on risk assessments
    • Changes throughout the document to the terms flammable and combustible liquid to align with the ignitible (flammable and combustible) liquid terminology updated in NFPA 30, Flammable and Combustible Liquids Code
