Natural Gas Emergency Response Protocols

The main objectives for dealing with flammable gases are evacuating civilians, isolating the leak source, and controlling the leak.
Key actions upon arriving at the scene include size-up, establishing command, determining incident level, requesting resources, establishing accountability, securing the area, controlling ignition sources, and establishing hot, warm, and cold zones.
Specific protocols exist for vapor discharge in open air, confined areas, and vapor fires in pipelines, including steps for evacuation, re-routing traffic, and contacting technical assistance.
Tactical objectives for dealing with the smell of gas in a structure include confirming gas presence, shutting off the gas, isolating ignition sources, and ventilating the interior.
Precautions include the potential for flashback, explosion, and vapor collection in high areas.
Procedures for dealing with compressed natural gas incidents involve evacuating civilians, securing ignition sources, and cooling exposed containers in case of a fire.
Primary tactical objectives for such incidents are isolating ignition sources and turning off the tank valve.
The first responder on the scene must follow the department's IMS Protocol, determine the incident level, request resources, establish accountability, secure the area, control ignition sources, and establish hot, warm, and cold zones.
It is necessary to notify Teco for all leaks or ruptures of natural gas distribution lines.
