I'm no firefighter, but this is NOT how you deal with an EV fire! The only way to stop this is to break the thermal runaway chain, which is happening at cell/module level, within the overall pack under the vehicle. Fire extinguishers and conventional hoses that are incorrectly directed stand little chance, as specialist 'under-body' lances are required to directly spray (and/or penetrate) the battery pack. Fire brigades should now be carrying these as a matter of course. EV firefighting needs specialist equipment and training, not to mention CIRIA 736 Containment systems for the prevention of pollution assessment; for the fire water run-off (Client/facility obligation). At best, a whole-car fire blanket could be used to prevent rapid spread to other adjacent vehicles, IF there was sufficient safe space for access and deployment. Both the construction and fire industry need to become more EV savvy, and quickly! 😱 #fire #evcharging #evehicles #batterytechnology

Whether giant fire blankets can be deployed to extinguish the flames of some electric cars? In general, vehicles contain materials that can catch fire, such as gasoline, oils, etc. These types of fuels go out if they don't have a supply of oxygen. This is the principle that makes a car fire blanket effective, as fully covering the vehicle prevents air from accessing and fueling the flames. On the contrary, extinguishing a fire in an electric vehicle is more challenging because when its batteries are subjected to high temperatures, the acids inside can undergo a chemical reaction known as "Thermal Runaway." Depending on the material the batteries are made of, their acids can release flammable gases that feed back into the flames, and at the same time, the heat from the flames feeds the chemical reaction of the acids. This chain reaction means that using only a car fire blanket is not sufficient to smother the electric vehicle fire. Even though using a blanket will prevent oxygen in the air from feeding the fire, it will be the gases from the battery itself that continue to fuel the flames. Therefore, when a "Thermal Runaway" type of reaction occurs in an electric vehicle's battery, car fire blankets are useful not for extinguishing the fire but for controlling the flames, minimizing the spread of heat and toxic fumes, preventing the advancement and spread of the flames, avoiding damage to other vehicles or elements in the surroundings, and above all, enabling emergency services to work more safely. An ideal solution for Emergency Fire Responder to tackle fires parking garages, underground and above ground parking lot in shopping centers, hospitals, hotels, Marina boat ferries, car dealerships lay down yards , paid parking lots in metropolitan areas, etc.
