Self-built battery storage reported to have exploded in a basement fire

What happened

A published report says a self-built battery storage system exploded during a basement fire and that a firefighter was injured. The town, the date of the fire, the operator and the extent of damage are not given in the material available to the register.

Contributing factors

The report describes the storage system as self-built. No further cause has been reported.

Lessons learned

1. Self-built battery storage can fail violently in a home and should be treated as a live hazard.
2. Responders should expect explosion and thermal-runaway risk when a basement fire involves battery storage.
3. Until a fuller account is available, no specific product or installation fault should be inferred.
