Why is special fire fighting equipment needed for electrical and non electrical fires?
Water conducts electricity and is therefore contraindicated for use on energized electrical equipment, however it is much cheaper than the chemicals that can be used on energized equipment making it more economical when water is able to be used. Similarly water should not be used on grease fires as it will spread out the grease and the fire rather than smothering it. Water if pure without contaminants does not conduct . Having stated that electrical fire can hardly be contained by water since the air itself will conduct electrons by ionization. So to contain an electrical fire a the oxygen must be removed and water will not do that.
Is Electricity the greatest invention?
no that would have to be transportation. we could easily live without electricity. just make a fire and cook your food over that
Why is it important to follow safety rules in using electricity?
to prevent accidents that came from electricity.like fire
How much electricity starts a fire?
Any kind of spark can cause a fire in the presence of an accelerator like gas fumes. It can happen even with a 1.5 volt battery.
Is it true or false that electricity is a form of fire?
FALSE. (they are different forms of energy) "Fire" is a release of thermal energy from a chemical or electro-chemical reaction. The ensuing radiation can have visual components (photons) as well as infra-red radiation (heat). "Electricity" is the conductive flow of electrons through a material, medium, or vacuum. Energized electrons (current) flow into a material or device at the anode and out at the cathode.
Should a stove fire be put out with water?
NO, use salt! Unless its a grease fire only use water as a last resort (ie you have no salt and cant blow it out) NEVER USE WATER ON A GREASE FIRE!!!!!!!!!!!!!!
What action to take on a cooking fire?
If the fire is in a pan, the best action is to put the lid on it. Never pour water on a grease fire, as this will splash the grease and spread the fire. Baking soda will also put out fires. Of course, if the fire is too large to safely fight yourself, you should evacuate the house and call the fire department.
Should you use a fire extinguisher to put out a grease fire?
Yes, a fire extinguisher works on a grease fire. What you have to avoid with grease fires is throwing water on them, because the burning grease will just float on the water and will be splashed around as the water heats and vaporizes, spreading the fire, rather than being put out. But the carbon dioxide based fire extinguisher doesn't have that problem.
What type of fire should not be extinguished with water?
Grease Fires!
Why do you not use water to put out fat fire?
You never use water to put out a fat fire, because the pouring water on burning grease or oil will not extinguish the fire. It will only cause the burning oil to splash, spreading the grease fire around.
What can be a problem when you cook on grills full of grease?
Sometimes the grease build up on a grill will flare up and burn off. Depending on where the grease is in the grill, it could burn the food you're cooking. The amount of grease there determines how long it will burn. You should never leave a grill for long, and always keep an eye out for fire.
How do you put out an oven fire?
First turn off the oven. If the fire is because of grease spewing, then cover it up with a pan to smother it. If it won't go out then fires should be doused with baking soda or a fire extinguisher - but not water on grease or electrical fires.
Why a fire should never be approached unless it is safe why not?
why a fire should never be approached unless it is safe to do so
How can a grease fire happen?
Grease fires are created when the heat starts to get hot enough to turn the grease towards a gas, creating fire
When you hear the fire alarm you should never?
You should never ignore it.
