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.
What should be the distance from electrical outlet from a water tank?
2 Meters
What fire extinguisher do you use on a electrical fire?
Water is good as it will cut off oxygen and cool the heat source. Powder and foam will smother to cut off oxygen. Carbon Dioxide (CO2) will cut off oxygen but blast of gas may spread ther fire by blowing light material such as paper causing it to set fire to other things. Don't use water on oil, or a chip pan fire.
Why must an electrical circuit be closed for energy to flow?
The electrical circuit is analogus to the water piping system. The word "close" means connection of a switch to get a complete circuit and to a water system you open the valve to let the water flows. Likewise if there is a connection the electrical energy flows. If "open" that means disconnected and for water piping system closing the valve to stop water flows. Therefore "close" for electrical ciruit means "open" for water piping system, and "open" for the former means "close" for the latter.
Why is the accumulation of moisture dangerous in electrical appliances?
The water can cause circuits to short or ground out, with hazards of electrical shocks or fires.
Why extremely dangerous to use a hair dryer while sitting in a bath?
Using a hair dryer near water can lead to electric shock because the water is a good conductor of electricity. Electric shock can be fatal when a person is immersed in water and the hair dryer comes in contact with it. It is important to keep electrical devices away from water to prevent accidents.
Why is it important to use the correct fire fighting equipment 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.
What should you do if you accidentally spill water near electrical equipment?
Immediately turn off power to the equipment if it is safe to do so. Unplug the affected equipment if possible. Allow the area to dry completely before attempting to use the equipment again to prevent the risk of electrical shock or damage.

Why should a water fire extimguisher not be used for putting out a fire in electrical equipment?
Water conducts electricity So the current could go back up the stream of water and electrocute the user
Why should you wipe up straight any water spilled on the floor in a laboratory?
Wiping up water spills immediately in a laboratory helps prevent slips, falls, and contamination of experiments or equipment. It also reduces the risk of electrical hazards and maintains a safe working environment for researchers.
What is the primary reason not to work on electrical equipment in a damp area?
Working on electrical equipment in a damp area can increase the risk of electric shock. Water is a good conductor of electricity and can lead to short circuits or malfunctions in the equipment, posing a serious safety hazard. It is important to ensure that the area is dry before handling electrical equipment to prevent accidents.
Electronic equipment and water?
Water is such a great conductor of electricity the equipment should work great under water. Check the manual though to be sure.
Do fans work in water?
Yes, fans can in fact work in water. These type of fans are called misting fans. However, they are not usually operated by an electrical circuit, as this would cause electrocution.
What type of extinguisher should be used on an electrical fire?
A water-type or water-based foam type of extinguisher should not be used on an electrical fire because water and foam are electrical conductors and could result in electrocution of the person using the extinguisher or anyone stepping in the water.
Should a gasoline or electrical fire be put out by water?
Neither a gasoline or electrical fire should be put out by water. A gasoline fire should be put out by a fire extinguisher labeled A B C. An electrical fire should first have the power switched off. Then the fire extinguisher should be used.
What type of fire extinguisher should be used on an electrical fires?
A water-type or water-based foam type of extinguisher should not be used on an electrical fire because water and foam are electrical conductors and could result in electrocution of the person using the extinguisher or anyone stepping in the water.
