Fire suppression and firefighting
432 lessons from 386 energy incidents, newest first, grouped by technology. Each is taken from the entry it links to, which has what happened and the sources.
Battery storage 56
Record the fire service response even when early reports give little detail.
Fire services attend full responses to BESS electrical faults even when no fire occurs, so sites should brief responders on automatic trip functions in advance.
Operators should agree isolation steps with the network operator in advance so fire crews can act quickly.
A battery energy storage system that overheats can enter thermal runaway and explode after fire crews arrive, so responders need remote isolation plans before entry.
Record which facts on battery fire damage are confirmed by inspection or the fire service and which remain unverified.
Lithium-ion BESS fires in containers cannot be extinguished directly, so sites need design features that allow prolonged external water cooling and drainage.
Limited experience with BESS incidents means local fire services need pre-planned response strategies from site operators.
Battery storage fires may need mutual aid from several fire brigades, so operators should agree response plans with all nearby services in advance.
Oil filled transformers near battery units add fire spread risk, so site layout must include adequate separation and suppression.
A reliable local fire water supply at BESS sites supports effective emergency response.
Solar panels on a property with a BESS fire complicate firefighting, so installers must plan access routes and isolation points at the design stage.
Fire services must coordinate with utilities to de-energise battery facilities before interior work begins.
Battery fires in enclosed rooms can last many hours, so response plans must allow for multi-day incidents with external water supply.
Water supply logistics for battery fires can limit response at sites without hydrants, requiring pre-planned tanker shuttling.
Lithium ion battery fires need perimeter cooling and controlled burn out as direct extinguishment is difficult.
Sprinkler systems can limit fire spread inside storage buildings.
Where lithium battery fires have produced toxic run-off, a controlled burn may be chosen, but smoke warnings for nearby residents need to be planned in advance.
Contact with the installer during the incident allowed firefighters to separate the DC connection and move the unit safely.
Lithium-ion battery fires in containers are hard to extinguish, so operators should plan for extended isolation and response times.
A lithium-ion battery container fire can produce firewater runoff that reaches a creek, so operators should fit shut-off gates at pond outfalls.
A battery fire on a food production site need not halt operations if runoff is contained, so clear protocols should be in place.
Fire service response plan should record the tactic of controlled burn out with exposure protection for adjacent units.
Occupants may have to leave before firefighters arrive, so a clear way out matters.
NOVEC 1230 fire-suppression gas combined with firefighting water at a BESS site can form PFPrA at 10,000 parts per billion, so operators should test suppression chemistry for persistent environmental byproducts before use.
Automatic suppression in colocated solar and storage sites can limit damage to a tiny fraction of capacity.
A lithium battery container can explode after initial cooling with a cutting extinguisher, so operators should keep exclusion zones during any move or response.
Fire services need pre-agreed protocols for lithium-ion units that use water curtains rather than direct water application.
Fires in indoor lithium-ion battery installations can burn for many hours until stored energy is consumed, so plan incident command and water supply for extended operations.
Pre-agree tactics with fire services for enclosed battery sites, including remote water cannons and controlled drilling to reach the fire without entering.
Design battery storage buildings with access points, smoke extraction and clear layout marking to support external firefighting.
A lithium-ion battery container at the Automotive Campus showed thermal runaway, so operators must confirm aerosol suppression works and plan for continuous cooling.
Two 30-tonne containers at the site could not be moved by fire brigade equipment, so plans must include access to suitable heavy-lift vehicles.
Lithium ion battery fires cannot use water hoses, so response plans must specify metal extinguishers and controlled cooling from the outset.
Confirm that local fire services will apply the agreed suppression approach for the unit type before energisation.
Battery fires require plans for burn-out periods as direct extinguishing is not used.
Suppression systems should be designed for extended thermal runaway events, since full extinguishment of a battery fire can take considerably longer than typical response timeframes.
Water hoses in battery storage suppression systems must be inspected regularly for leaks that could contact energised racks and cause shorting.
Melted battery racks found after a water leak show that suppression system design must prevent water reaching live cells.
A repeat water leak event at an adjacent phase requires review of shared suppression system specification and maintenance across the whole site.
Module level containment reduces the need for external fire crews, so response plans can focus on isolation and exclusion zones.
Agree escalated multi-agency response with local fire service before energisation, covering access and isolation.
A lithium-ion BESS fire may require robotic entry to assess gases before any person goes inside, so operators should arrange remote entry tools with the fire service in advance.
Sprinkler systems in battery storage buildings are designed for containment over many days, so plans must cover prolonged water supply, drainage and run-off control.
A prior explosion at a nearby battery site led to a defensive response here, so local fire services should embed earlier incident findings in pre-plans for similar facilities.
Lithium ion battery fires at grid storage sites can release smoke for hours so operators must provide safe access routes for extended on site firefighting.
Targeted sprinklers can contain battery module overheating before it becomes open fire.
Fire crews need prior briefing on battery layouts, as a structure fire call may mean no flame.
Fire protection and isolation plans for BESS during commissioning must allow for rapid energy isolation, as the container was destroyed despite extended firefighting.
Gaseous clean agent suppression cannot stop cascading thermal runaway in lithium ion systems, so add ventilation and cooling.
Bulk storage of 2000 loose lithium-ion packs in one warehouse allows rapid thermal runaway spread, so sites should install integrated suppression or divide stock into smaller compartments.
Firefighters took two and a half hours to control the blaze, so remote isolation and debris exclusion zones must be pre-planned for outdoor sites.
Gas-based suppression in lithium-ion ESS may fail to cool thermal events, so operators should fit systems rated for battery fires.
Fires in prefabricated sandwich panel enclosures need suppression suited to the structure.
Battery storage sites need dedicated fire water within 90 metres. Operators must confirm hydrant access in writing before commissioning.
A battery rack fire in a partially assembled BESS can spread to adjacent units when doors are open and the container suppression system is not yet active.
Water cooling after initial foam application can limit heat spread in lithium-ion battery fires even if the fire is not fully extinguished at once.

Record the outcome after the incident, including whether the fire was extinguished and whether it spread, so an attendance note is not read as a finished account.

Wind turbine fires at height are often left to burn out because firefighting at elevation is difficult.
Agree in advance how the site and the local fire service will work together.
Ground crews may not be able to reach a fire high in a turbine, so access, isolation and a response agreed in advance with the local fire service matter.
