What should be used for fires involving electrical equipment?
Class C fires involve energized electrical equipment. Extinguishers with a C rating are designed for use with fires involving energized electrical equipment.
Why water should not be used on fire involving electrical equipment?
But water conducts electricity, so if the spray water on to electrical equipment the could electrocute. Large electrical distribution centres often use fixed sprinkler pipes and spray head which are heat activated to quench fires. The water does not short circuit and trip fus es further into the electrical grid.
Why is water not used in controlling electrical fuse?
As we know that water is a very good conductor of electricity so it has a high tendency to carry electricity which can be harmful, therefore it is not used in controlling electrical fire…..
Which of these is the best to used on an electrical fire?
The best way to put out an electrical fire is with a fire extinguisher. If you don’t have one, remember these tips. 1. You should never throw water on an electrical fire because water conducts electricity and you could be electrocuted.
Which thing is used to control fire?
Steam is used to control fire in confined areas, while inert gas is employed to extinguish gas, dust, and vapour fires. Fire fighting is a battle against time.
How does carbon dioxide control fire?
Carbon dioxide covers the fire and cut-off the contact of oxygen and fuel. This is because carbon dioxide is heavier than the oxygen. … When carbon dioxide is released, it expands enormously and cools down. Due to this temperature it brings down and this helps in controlling the fire.
Why does water control fire?
Water puts out fire by creating a barrier between the fuel source and the oxygen source (it also has a cooling effect which has to do with the energy required to convert liquid water into water vapor). It does this because it is a completely, 100% oxidized material.
Why is water not used in controlling electrical fuel?
Water is not used in controlling electrical fires because water is a good conductor of electricity and it may give severe electric shock.
What would happen if water is used to control fires involving electrical equipment?
Water is a good conductor of electricity. If used in fires involving electrical equipment, it will cause electric shocks or short circuit.
