The extensions are a convenient way to power tools and devices on a temporary basis. They are also the main cause of electrical fires, and can cause injury and even death if used incorrectly.
An estimated 3,000 residential fires originate in extension cords each year, and 300 people are killed or injured. More than half of the injuries involve fractures, lacerations, contusions and sprains caused by tripping over cords. One person was electrocuted in the house every 36 hours, and electrocuted in the workplace every 24 hours. Electrocution ranks as the fourth leading cause of industrial deaths. Death of 0 volts represents 12 percent of global electric shock.
Continued use can cause the insulation on the cord to deteriorate rapidly, creating electrical shock and fire. Some basic safety practices of the extension include:
- Inspect the cord for damage before each use. Throw it away if it is damaged.
- Do not run the cord through walls or ceilings, as they may overheat.
- Keep extension cords away from high traffic areas where they become tripping hazards.
- Insert plugs fully so that no part of the tooth is exposed.
- not staples / nails extension cords to walls or baseboards.
- Make sure extension cords are UL, CSA or ETL certified.
- Read and follow the label and the manufacturer's instructions.
- Stop a cord feels hot.
- Make sure extension cords are properly assessed for their intended use, whether it is inside or outside.
