National Grid personnel will respond to assist you, mitigate the leak, render the area safe and then restore service. In general, National Grid personnel will report presence to the incident commander (IC), coordinate action and work together to resolve the situation. Based on policy, National Grid personnel are responsible for doing the following:
- Inform the IC of the arrival of National Grid Personnel and offer assistance. National Grid recognizes that an emergency incident is under the purview and control of the IC and will offer assistance.
- Inquire if the gas source has been controlled, provide guidance as it relates to the gas distribution system and mobilize resources to control the leak.
- Offer to work with the IC as a non-governmental organization (NGO) in the incident command system. Typically, this is referred to as developing a unified command.
- Secure gas to the compromised gas infrastructure and work to eliminate ignition sources in proximity to the leak.
- Upon request from the IC, work to detect combustible gas in structures that may have been impacted by the event.
- Work with the fire department to ventilate structures, manholes, vaults and other sealed spaces or areas that have accumulated gas.
- Coordinate with other utilities whose infrastructure has been impacted.
- Shut off all services fed by the compromised gas infrastructure.
- Provide public information to the media.
- Restart gas service impacted by the event once the compromised infrastructure has been repaired and the isolated area has been pressurized.
