Study Notes

General Guidelines and Safety Considerations

All TFS personnel working in a Controlled Area must wear full PPE, SCBA with face-piece worn for the duration of the event.
No LIB assemblies or ESS containers will be opened or overhauled for safety.
Upon confirmation of a LIB event, Heavy Haz and Haz Support will be requested if not already dispatched.
Canutec (*666) is the primary resource for information and should be used as a reference to confirm all on-site information.

Ejected Cells and LIB Removal

A thorough search for ejected cells must be completed and announced as a benchmark to the Incident Commander.
Any unaffected LIBs in the vicinity should be removed using non-conductive tools to prevent their involvement.
No TFS member will hold the battery or cell in their hands.

Hazardous Materials and LIBs

LIBs are to be considered energized even after they have been shut down or discharged.
Damaged, discharged LIBs may still contain a charge referred to as stranded energy.
Non-conductive equipment should be used at these incidents where deemed a necessary safety precaution.

Evacuation and Safety Precautions

Larger evacuation areas in high-rise buildings may be required due to the production of higher levels of toxic and flammable gases.
Firefighters must stay out of the vapour cloud.
E-bikes and mobility devices situated in the entryway to apartments may block escape for residents in a fire situation.

Incident Command and Communication

Incident Commanders, Company Officers, and all crews must consider the use of non-conductive equipment at these incidents.
The Hazardous Material Unit, along with the IC, will develop a plan for isolating the LIBs in their present location and/or on how to proceed with their removal.
Incident Commanders will use a TFS supplied cell phone to take pictures of the batteries involved and send to the Division Chief (DVC) Fire Investigations.

Post Incident Procedures

Post incident decontamination will be undertaken by crews that have been exposed to smoke, vapours, or other contaminants during the incident, as per TFS TN 104.2.

Incident Actions for Fires

Water is the primary extinguishing agent to be used.
Water should be used as a cooling agent for exposed LIBs.

Electric Vehicle Fires

EV fires present other concerns for the Incident Commander when developing their IAP.
EV fires in unvented, single-family garages may provide the perfect conditions for backdraft or explosions due to the build-up of gases inside.
The Incident Commander should develop an IAP considering the use of smaller entry doors as their primary avenue of attack.
EVs connected to charging stations should have the power shut down/disconnected as soon as possible.
