G-LESS LIBs and ESS Part 2

Incident Operations

• If responding to a commercial or utility installation, follow Site Pre-plan and do not enter the ESS installation.
• For residential responses, shut off power to the unit, ventilate the area, and protect exposures.
• Contact the manufacturer, emergency contact, or on-site Support as soon as possible.

Confined Space Incident

• Do not enter an ESS vault, consider it a Confined Space Incident, and follow current TFS SOGs and Training Notes.

Water Safety

• Water may not prevent a battery from entering thermal runaway.
• Water can provide a cooling effect on adjacent battery cells.

Hazmat Response

• If the manufacturer or on-site Support is not available, consult with the Hazmat Captain, Incident Commander, and possibly CANUTEC.

Post-Incident Decontamination
