NFPA 120 PDF

Highlights

The 2023 edition is revised to include the latest industry knowledge and best practices for helping to safeguard these operations.
Notable changes include:
New ventilation requirements added in Chapter 4 to reduce combustible gas concentrations in mines
Several new requirements for conveyors introduced in Chapter 9 for fire detection in reclaim tunnels, the location of monitoring equipment, and cleaning conveyor systems to mitigate combustible dust buildup, as well as egress and secondary escape requirements in below-grade, reclaim conveyor areas
Revisions 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
