A library built for aspiring future firefighters, students studying fire science and/or in academy and current volunteer and career Firefighter to have a platform of knowledge for all to enjoy. Created by a firefighter for all firefighters, learn and grow with me as I organize and expand on all aspects of a firefighter: Hazmat,Rescue, Equipment, Truck,Ladder,EMS and more.
How to Approach and Extinguish an Electrical Vehicle Fire. Approach in full hazmat gear, keep people away from the toxic smoke and wait for the fire to go out. Don't forget to get the fire truck fully decontaminated and toss that hazmat gear in a sealed container for disposal.
SERIOUSLY? Your telling me that in 2022 the "Best" way you have to put out an ELECTRICAL fire with FREAKEN WATER? There HAVE to be BETTER ways to put out electrical fires such as ways of quickly sucking all the oxygen from the area. If a vehicle is still producing electricity aren't you just ASKING to be electrocuted by dumping thousands of gallons of water on the ground? LOL.
I have a premium account with RU-vid and couldn't figure out why I was getting advertisements. I tried clicking "skip video" several times. lol. Then, I saw the pop-ups, etc.
There is no potential against earth, so any currents are localized to the car. It is only dangerous if you are directly working at the car, for example if you want to disconnect the battery. This is different to normal power distribution, for example when an overhead line comes down after an accident, where potential against earth is present.
Water (H2O) is non conductive. Tap water will, but shunting between terminals is minimal. After using water to lower the temperature so that the other blocks don't start thermal runaway, they've measured the electric tension (there is no such thing as "voltage" ) and the effect was minimal (unfortunely)
There is only little elemental lithium in a battery (for example, in a Tesla there is about 5kg lithium), and the cooling down you get from water easily outweighs the undesirable effects from some of the water getting converted to hydrogen and participating in the fire.
There is no metalic form of lithium there. That's the disposable you buy for photografy work or similar use (Sony lithium AS for instance, I have one for tests)
Laminated I Joist are 60% glue & go up in flames rapidly. They also fail or collapse in a matter of minutes when exposed to flame. Some fire departments are requiring a label in various neighborhoods that have installed them.
How about CO2, ABC dry chemical, powder graphite, copper powder or sodium carbonate fire extinguishers? Check also the Bridgehill fire blanket and the F-500 foam agent.
But CO2 is very limited in quantity. In an urban setting, water from a fire hydrant is basically unlimited, so you can cool down the car and surroundings as long as it is required.
Yes, lithium solid reacts explosively with water, however when lithium is ionized in a substance, such as that found in a battery, the lithium ion is unreactive. This is similar to how sodium reacts explosively with water, but the sodium ion in sodium chloride (table salt) doesn't react with the water when dissolved.
In lithium ion packs it’s a chemical fire. Smothering it won’t put it out. Doesn’t hurt but isn’t going to change things, your focus is cooling it down below the runaway point.
