Battery Storage.
Specialist Protection.

Specialized fire detection and suppression for lithium-ion battery storage systems (BESS). Designed for the unique risks of modern battery installations.

The Service

Lithium-ion is a different kind of fire. It demands a different kind of protection.

Battery Energy Storage Systems (BESS). Lithium-ion battery banks for backup power, solar integration, EV charging, and grid-support applications. Represent a rapidly growing fire risk that most traditional protection systems can't address. A lithium-ion thermal runaway fire burns hotter, releases toxic gases, and can reignite hours or days after it appears extinguished.

Boss Fire is one of the few Canadian commercial fire protection companies with specialized NFPA 855 expertise in BESS protection. We design and install detection, suppression, and containment specifically for lithium-ion risks. Often in partnership with the BESS vendor.

If you have or are planning a lithium-ion battery installation. Especially one over 20 kWh. Get a Boss Fire assessment before your insurer does.

Questions

Frequently asked.

Why can't a regular sprinkler system protect a battery storage installation? +

A lithium-ion battery in thermal runaway generates its own oxygen internally. Water alone can't "starve" the fire. Plus, water on burning batteries can release toxic and flammable gases. Effective BESS protection requires detection of early off-gassing (before the fire starts), specialized suppression agents, and proper compartmentalization. NFPA 855 lays out the full framework.

Is BESS fire protection required by code? +

In most Canadian jurisdictions, lithium-ion battery installations above a threshold size (typically 20-70 kWh depending on location and occupancy) trigger NFPA 855 compliance, which includes specific fire protection, ventilation, and separation requirements. Boss Fire can review your installation against current code.

We already have a BESS installed. Can you retrofit protection? +

Yes. Retrofitting is common and often more cost-effective than a full redesign. We assess the existing installation, identify gaps against NFPA 855, and propose targeted upgrades. Detection, suppression, ventilation, or containment. To bring the system into compliance.

Do you work with BESS vendors and integrators? +

Yes. We regularly partner with solar installers, EV charging providers, and battery vendors to bundle fire protection into new BESS installations. Having Boss Fire involved before installation is almost always faster and cheaper than retrofitting later.
