If you find yourself working around power lines, make sure you are aware of your proximity to them at all times. Or are they frayed and worn out check all power cords on a regular basis – are they in good condition? Namely because throwing water on them may not work and can actually make the problem worse electrical fires are among the most dangerous types of fire.
If any electrical equipment catches fire, it should be unplugged or the power interrupted at the main switch. And keep ladders, poles, make sure others in the area are aware of any power lines or electrical hazards, and other equipment at least 10-15 feet away from any power line that you see.

(UL), indoor or outdoor, ETL or MET labs, CSA, and are properly rated for their intended use, and meet or exceed the power needs of the appliance or tool being plugged into it. Fire extinguishers are the preferred tool when battling an electrical fire, and any call to the fire department should include the information that they are dealing with an electrical blaze Ensure extension cords and electrical products are listed by an independent testing facility such as Underwriters Laboratories Inc.
Any outdoor cords should be designed for outdoor use and properly equipped with a Ground Fault Circuit Interrupter (GFCI) to prevent the risk of shock. Power tools should also be switched to the "off" position while they are being plugged in to avoid injury. Contact the local utility company before starting any work if lines are underground.
Any electrical hazards should be immediately reported to your superior. Electrical issues can commonly be addressed through a simple inspection of the workplace and "shockproofing" the environment. Make sure this procedure is followed to the letter in order to avoid injury or electrocution. Power tools should never be carried by their cords since this could result in the cord being broken or frayed.
