Make sure that all electrical equipment is properly grounded. Inspect electrical equipment regularly for frayed or worn cords. Exposed wires can cause a serious safety hazard. If there are any wires that you can see that are visually exposed report this situation immediately and disconnect the offending wire or plug. Under no circumstance should there be a surge suppressor power strip plugged into another surge suppressor. Also there should never be an extension cord plugged into a surge suppressor power strip. These conditions are a fire hazard and are against the City of Davie fire code. Please remedy the situation if you find a plug configured in this manor.
