b'Incident Response StepsThis is common practice for larger incidents and those involving liquid spills impacting the environment.UnifiedCommandPipeline Company EOC Responsible PartyRepresentative(s)SafetyLiasionInformationPipeline Personel Operations Planning Logistics FinanceUnified command incorporating authorized operator personnelControl Fires, Vapor and LeaksBecause there are many variables to consider, the decision to use water on fires or spills involving water-reactive materials should be based on informa-tion from an authoritative source, such as the pipeline operator, who can be contacted by calling the 24-hour emergency phone number listed on a nearby pipeline marker sign.WARNINGSome products, such as anhydrous ammonia, can react vio-lently or even explosively with water. Water getting inside a ruptured or leaking container may cause an explosion or the products reaction with water may be more toxic, corrosive, or otherwise more undesirable than the product of a fire without water applied. Consequently, it is best to leave a fire or leak alone except to prevent its spreading.Fire ControlExtinguishingaprimaryfirecanresultinexplosivere-ignition.Unlessit is necessary to save human life, flammable gas fires should NOT be extin-guished on flammable gas pipelines unless the fuel source has been isolated and the pipeline operator advises you to take this action! If the fuel source is not shut off and the fire is extinguished, leaking gas can migrate away from the pipeline and find an ignition source.Let the primary fire burn. Eliminate potential ignition sources.Coolsurroundingstructures,equipmentandvessels.Becausewater is an inefficient and even dangerous way to fight fuel fires, use a fog pattern, NOT a straight stream of water. Please note some products are not compatible with water; refer to the DOT Emergency Response Guidebook.25 2023 by Pipeline Association for Public Awareness'
