Stay up to date on recommended practices for emergency planning and response to hazardous liquid and gas releases.

From the physical environment and the amount of liquid or gas released to how it is confined and risks of possible ignition sources, there are a variety of factors that determine the severity of an emergency. NFPA 329, Recommended Practice for Handling Releases of Flammable and Combustible Liquids and Gases, provides first responders, spill response organizations and contractors, facility safety staff, and municipal personnel with the latest best practices for emergency planning and response to these hazards.

This document can help users prepare to orchestrate an appropriate response to fire, explosion, and human health hazards resulting from liquid, gas, or vapor that may migrate to a subsurface structure and covers the following:

• Flammable and combustible liquids and gases fires, explosions, and sources of ignition
• Initial response recommendations, including indicators of a release, initial response to physical discovery, eliminating sources of ignition, and entering the area
• Searching for the source and procedures to verify the source
• Detecting releases from tanks and piping
• Tracing liquids underground
• Removal and disposal of flammable and combustible liquids
