Can pkp be used on a charlie fire?

Answer 1

Yes, but I would recommend CO2 and from more than 3 feet away i short burst and the base of the fire. First call the fire department for backup. IF you turn the power off first it is more safe. You can call the fire department unplug the device or get to the circuit breaker. If there is a capaciter in the electronics, it can hold thousands of volts of electrcity even with the power off. These capaciters are in old TV's and other electronic things. A Charlie fire is an electrical fire and the condensate from a CO2 and the cold builds up water which conducts electricity. So, small busrt of CO2 and the base of the fire, which is the low part where heat is rising and would be turning black. More than three feet away or the electricity could jump back. Some restaurant kithcens have a build in pasty dust that sprays down for you from a light off station far enough away. Always make sure the aluminium foil is not glogged up by grease. This will cause the pasty dust to spurt on the fire which could force hot grease all over the place. Chefs should always clean these carefully and check them. A lid put on top of a grease fire will stop the fire because of no oxygen and turn the heat off. Be carefull not to spray a grease fire hard. It will only spread the fire all over. You can use an all purpose fire extinguisher, but if you can avoid I would. You should do a test spurt to see how strong the exinquisher is and maybe you can judge how hard to pull the trigger and how far away in order not to spray the grease onto paper towels or kitchen rags. A gas fuel fire is a beta fire and PKP is great for those. Use a sweepng motion at the base careful not to spray the oil or gas from the pressure. So not to close. Water will work with a sweeping motion if you don't have PKP. Again use a sweepng motion and work you way back without splashing the fuel especially if is getting pushed back to a wall. More gentle spray as you get back to a wall with fster sweeps. Be sure the fire does not get around you. Sweep the spray all the way accross the fire. The idea is to separat the oxygen from the fire. A delta fire is metal like magnisium. These have to be smoothered by sand. New BMW car now have magnisium engines. These fire are receivng oxygen from the metal itself and you have to separate the outside oxygen supply and heat of the metal itself. Alpha fires are wood and materials and water works best. Water can be used one an elecrical fire. I was in the Navy as a firefighter and I beleive it is a stream of water 24 feet away can hit less than 24000 volts. Best solution is call the fire department. If you smell sulfer it might be natural gas. Get out of the house or building immediatly. Any spark including a phone can set those off. Call from somewhere else. Pliers can shut the valve off outside and there is tool you can hide outside for that. If you are stuck in a house with a fire stay low. More people die from smoke inhalation than the fire itself. Sad thing is you may be only unconcious while burning to death. You can also tie two sheets together and tie them to a bedboard leg to climb down a second story window. Open the window when you are ready to go. The window open will allow the air to get out and the fire will be drawing more air in from door and window seems. If you suspect a fire and want to try and find it use the back of you hand to check heat from doorknobs. If you have to go in to save you daughter or something. Stand to the side when opening the door if it is hot for a few seconds. If the room is close to 411 degrees opening to door will allow the fire to get oxygen fast and to jump to 411 which causes spontanius combustion and a backdraft. It can even be an explosion. I beleive there is a fold up ladder the fire department can get you for getting out of second story windows. It is a chain ladder or something. I am thinking about trying to get one. And they are supposed to be cheap throughn them.
