Temporary or permanent electrical fixtures represent major fire hazards.  

Be careful!

• Avoid using a multi-socket adapter on the same circuit.
• Never remove the grounding prong from a power plug.
• Don't use nails or metal hangers to hang extension cords and don't make knots in extension cords. 
• Don't put extension cords under carpets.
• Don't use extension cords permanently.
• Don't connect several extension cords end to end. 

Tips:

• Have a qualified technician perform repairs and installations. 
• Use the correct amperage for your electrical circuits.
• Replace damaged extension cords.
