2015 Edition

Protect facility personnel in mines and reduce fire loss risks through prompt compliance with the 2015 NFPA 122.

Mining and mineral processing facilities represent significant fire and explosion exposures to both personnel and production equipment and buildings. Critical to safety, the 2015 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.

New in the 2015 NFPA 122.

• Changes align requirements with the 2015 edition of NFPA 120, Standard for Fire Prevention and Control in Coal Mines.
• Added materials on pre-engineered fire suppression systems include requirements for inspection and maintenance.

Stay up-to-code. Be confident your designs, installations, and facilities are protected and in compliance.

Mitigate hazards with the field's best practices in the latest NFPA 122. (Print, 42 pp., 2015)
