b'PIPELINE EMERGENCY RESPONSE GUIDELINESDo not inhale fumes, smoke or vapors. Once the primary fire is out, beware of hot spot re-ignition.Do not operate pipeline valves unless these actions are coordinated with the pipeline operator. It is important to wear proper protection and use appropriate chemical agents and equipment when containing the vapor release until the pipeline operator arrives on scene.Vapor ControlLimiting the amount of vapor released from a pool of flammable or corrosive liquids requires the use of proper protective clothing, specialized equipment, appropriate chemical agents, and skilled personnel. For these reasons, it is best to contain the hazards and wait for the pipeline operators representative to handle the pipeline and its product.Do not inhale fumes, smoke or vapors. Eliminate ignition sources! Flammable gases may escape under pres-sure from a pipeline, form a vapor cloud, and be ignited by an ignition source in the area. Explosions of unconfined vapor clouds can cause major structural damage and quickly escalate the emergency beyond responder capabilities.Do not ignite a vapor cloud! Pipeline operators will perform this dan-gerous task.Avoid forced ventilation of structures and excavations. Forced ventila-tion can actually increase the possibility of a flammable atmosphere.Limited fog misting can be of some benefit if knocking down a vapor cloud, especially if such a cloud appears to be spreading beyond the 26 2022 by Pipeline Association for Public Awareness'
