Safety for Electricians Module 2 Practice Test

The key idea is to remove the electrical energy first and then use the right tool to fight the fire. If you can do it safely, switch off the power at the breaker or disconnect switch to stop the current feeding the flames. Once the power is cut, grab a fire extinguisher that is rated for electrical fires, because these extinguishers are designed to be used around energized equipment without conducting electricity back to you. Do not use water on a fire involving electrical equipment, since water conducts electricity and can put you at risk of shock or cause the fire to spread. If you can’t disconnect the power safely, evacuate and call emergency services rather than attempting to fight the fire. Only attempt to put it out if the fire is small, you have a proper extinguisher, and you can do so without putting yourself in danger.
