Do not use electrical tools or appliances in a wet environment or outdoors, if it is raining. Only moisture resistant appliance cords should be used outdoors. Electrical outlets for outdoor use should be weatherproofed. Disconnect cords from outlets by pulling the plug, not the cord. Power tools require heavy duty electrical cords.
Electrical safety begins with proper wiring.
Wiring should be installed and checked by a qualified electrician. A minimum of a 200-amp service is recommended for a home. Use Ground Fault Interrupters for receptacles near water sources in bathrooms and kitchens, outdoors, in garages and in unfinished basements. Make sure that each family member knows the location of the main fuse or circuit breaker in the home and understands how to operate it in case of an emergency. If a fuse blows, only replace it with another fuse of the proper size.
