Multi-Outlet Power Strips
During recent fire safety inspections, multi-outlet power strips are often found on the floor or unattached to work surfaces, which makes this condition the most frequent problem noted in the inspection reports. Many multi-outlet power strips have a fragile internal connection that can be damaged by repeated movement or jarring. Fires have resulted when this connection is damaged, so it is important that the strips be above the floor and mounted to a fixed surface, such as a wall or cabinet.
Multi-outlet power strips are an acceptable substitute for extension cords if they are used sensibly. The following guidelines will help you make the best and safest choice for your use.
Examples of Appropriate Use of Power Strips:
Computers
Printers & Computer Peripherals
Fax machines
Televisions, VCRs
Overhead projectors
Electric fans
Radios
Power Strips May NOT be Used For:
Coffee Pots or mug warmers
Hot pots, crock pots or hot plates
Refrigerators or Freezers
Microwave, toasters or toaster ovens
Photocopiers
Portable Heaters
ANY other appliance with a high current (amperage) draw
Guidelines for the Appropriate Selection of Power Strips
- The safest type of power strip will have a fuse or reset button to prevent power overloads.
- Multi-outlet assemblies with built in surge protection are the preferred strip for computer usage.
- It is easy to exceed the capacity of the power strip and the circuit, so use some caution when adding multiple appliances to the strip.
- Do not use adapters or extension cords between the strip and the outlet.
- Never plug one power strip into a second power strip or into an extension cord.
- Periodically inspect the condition of the power strip, including the cord and plug, test the reset button, and make sure all plugs are firmly inserted into the outlets. If the power strip feels hot, or if a defect is found, discard the power strip and replace with a new one.
- Extension cords are allowed only for temporary installations (hours - days). Multi-outlet strips are built to be used for extended periods, and can be a safe substitute for an extension cord if installed properly.
Normally, the outlet strips will come with hardware or heavy duty double faced tape for mounting.
