Lithium-Ion E Bike Battery Sprinkler Save London

• Date of incident; 21/11/21
• Time of call; 05:07
• Location; Lanterns Way, Isle of Dogs, London
• Occupancy; High rise residential flats of 21 floors
• Fire involving a Lithium-Ion battery

London Fire Brigade have reported the above-mentioned fire which was extinguished by the activation of three sprinkler heads before the arrival of the LFB. The fire was contained within the five roomed flat on the 3^rd floor of the building, LFB’s fire investigation team believe the fire was accidental and caused a fault in a lithium-ion battery for an Ebike that was on charge.

This is the second sprinkler save reported involving a lithium-ion battery following the Stockport fire sprinkler save reported by Greater Manchester Fire & Rescue Service in July on this occasion involving a mobile phone. On both occasions the sprinkler system extinguished the fire before the arrival of the Fire & Rescue Service

The dangers of Lithium-Ion battery fires should not be underestimated which can develop into significant and unstoppable thermal runaway fires. It should be noted at present that sprinkler protection of lithium-ion batteries is outside the scope of current standard sprinkler design standards e.g., EN, NFPA/FM, specialist standards are being developed for example NPFA 855.

Once again, this incident demonstrates the benefits of installing a residential sprinkler system.
