ERG 2024 GUIDE Gases - Flammable 115 (Including Refrigerated Liquids) POTENTIAL HAZARDS FIRE OR EXPLOSION • EXTREMELY FLAMMABLE. • Will be easily ignited by heat, sparks or flames. • Will form explosive mixtures with air. • Vapors from liquefied gas are initially heavier than air and spread along ground.

As an immediate precautionary measure, isolate spill or leak area for at least 100 meters (330 feet) in all directions. Keep unauthorized personnel away. Stay upwind, uphill and/or upstream. Many gases are heavier than air and will spread along ground and collect in low or confined areas (sewers, basements, tanks).

The 2024 Emergency Response Guidebook provides first responders with a manual intended for use during the initial phase of a transportation incident involving hazardous materials/dangerous goods. DOT's goal is to place an ERG in every public emergency service vehicle nationwide.

Hydrogen and Deuterium fires are difficult to detect since they burn with an invisible flame. Use an alternate method of detection (thermal camera, broom handle, etc.) CALL EMERGENCY RESPONSE Telephone Number on Shipping Paper first. If Shipping Paper not available or no answer, refer to appropriate telephone number listed on the inside back cover.

· Structural firefighters' protective clothing provides thermal protection but only limited chemical protection. · Isolate spill or leak area for at least 100 meters (330 feet) in all directions.
