Fire Containers limited
Fire Containers limited has been formed to tackle the emerging risks associated with the use of Lithium-Ion batteries now being used as common place in the motor vehicle industry.
Our design team have backgrounds in the fire and rescue sector, design engineering and the vehicle recovery industry have combined our joint knowledge and experience to develop and build the worlds first Electric Vehicle Containment Unit (EVCU) with recirculating firefighting and cooling capability (Patent Protected).
Why do we need the EVCU?
We are seeing more and more electric and hybrid cars in the UK with an estimated 850,000 already on the roads in 2022 and expected rise to 23 million by 2032 just in the UK. At the end of 2021 the number of Electric Vehicles (EV) globally exceeded 16.5 million, but the expected global growth predicts this will rise to 350 million vehicles by 2030.
Emergency responders globally are now struggling to keep up with the development of these vehicles especially when involved in serious accidents of fires as the time it takes to extinguish a vehicle and remove it safely from the roadway.
When individual cells in a lithium-ion battery are damaged in the event of a traffic accident or if there is a fire in the car this can result in the development of heat in the cell, which then spreads from cell to cell – also known as thermal runaway. A chemical fire in a lithium-ion battery can develop very quickly producing jet like flames and harmful toxic gases. Heat can develop several hours, days or weeks after an accident has occurred.
“Putting out an EV fire demands large amounts of water, around 1,125 litres a minute and can take over an hour totalling 67500 litres of water in some cases crews have been on scene over 4 hours. This is water that becomes contaminated with soot and chemicals that then runs into public drainage systems or damaging the environment.”
A fire in a lithium-ion battery (LIB) is a chemical fire and does not require external oxygen supplies. In fact, the thermal runaway will continue even if the batteries are fully submerged in water. Vehicle manufacturers have already stated that their LIB battery packs should NOT be submerged as this can begin or accelerate the thermal runaway process (as recently seen in the floodings in America during Hurricane Ian). In addition submersion tactics create difficulties in removal from scene due to massive weight issues and also create tens of thousands of litres of contaminated water requiring disposal.
Unlike other units the EVCU does not rely on submersion tactics and utilises water to ‘Steam tactics’ to suppress fire development as water at 100 degrees creates an expansion ratio of 1700:1 meaning that with 1800 litres of water on board it can produce over 3 million litres of steam therefore suppressing fire growth and development. In fact, the hotter the fire burns the more steam is created.
Fire Containers Ltd. are proud to have designed and developed the Electric Vehicle Containment Unit – EVCU (patent protected). The first mobile solution for cooling and firefighting whilst on the move with its unique onboard water supply and suppression system.
