Electrical Extension Cords
|Mine Type: All Mines|
Electrical extension cords can be a source of fires and electrical shock when misused at the mine or at home.
- Use extension cords only when necessary and only on a temporary basis.
- Replace cracked or worn extension cords.
- Insert cord plugs fully so that no part of the prongs are exposed.
- When disconnecting cords, pull the plug, not the cord.
- Use only three-wire extension cords for tools with three-prong plugs. Never remove the third (round or U-shaped) prong. It is a safety feature designed to reduce the risk of shock or electrocution.
- If the body of the cord or the plug feels hot or if there is a softening of the plastic, it is a warning that the plug wires are failing. Do not use the extension cord.
- Do not use an extension cord while it is coiled or looped, and never cover any part of an extension cord with rugs while the cord is in use.
- Using nails or staples to attach extension cords to a wall or ceiling could damage the cord and present a shock or fire hazard.
- Don't plug in tools that exceed the rating of the cord.
- When using outdoor tools and appliances, only use extension cords labeled for outdoor use.
- Avoid plugging multiple extension cords together. This can lead to overheating.
