Before You Plug Into Electricity, Plug Into Electrical Safety—The Checklist
New Protection—Arc Fault Circuit Interrupters (AFCIs)
Newer arc fault circuit interrupters (AFCIs) can help prevent fires that often result from problems at the outlets, switches and frayed and cracked cords connected to the circuits. The AFCI senses the particular signature of an arc—where electricity has to jump through an insulating medium—and, like the GFCI, acts immediately to shut off the circuit, thus reducing the risk of fire associated with arcing faults.
AFCIs are currently required by the National Electrical Code® in new construction in all bedroom circuits, but should be considered in all homes and all general purpose receptacles. Consult a qualified, licensed electrician to determine if your home is compatible with AFCI protection.
Other technology
Over the years, we have begun to safety engineer our electrical products to include some of the same technology that has been applied to our electrical systems. Immersion detection circuit interrupters (IDCIs) and appliance leakage current interrupters (ALCIs) are typically found on hair dryer and specific appliance cords.
They operate in slightly different ways but perform essentially the same function. Leakage current detection interrupters (LCDIs) are protective devices that help prevent fires due to damage to cords. They are presently being built into the plug cap of room air conditioners. If the cord is damaged, the LCDI circuitry detects an abnormal condition and immediately shuts off power. LCDI technology is also available in select extension cords and power strips.
Batteries
When used correctly, batteries provide a safe and dependable source of power. However, if they are misused or abused, overheating, leakage, or in extreme cases explosion or fire, can occur. Follow these safety principles when using batteries:
- Always follow warnings and manufacturers instructions for both the batteries and the battery-operated product. Use only the correct type and size battery indicated.
- Check the contacts of both the battery and the battery-operated product for cleanliness.
- Always insert the batteries correctly with regard to polarity (-/+), matching the positive and negative symbols of both battery and product. Putting them in backwards, the product will sometimes still operate, but may inadvertently charge the batteries resulting in venting or leaking.
- Remove and safely dispose of exhausted batteries immediately.
- Replace all batteries in battery-operated products at the same time and with the batteries of the same type and manufacture.
- Do not short circuit batteries. When the positive (+) and negative (-) terminals of a battery are in contact with each other, the battery can become short circuited. For example, loose batteries in a pocket with keys or coins can be short circuited possibly resulting in venting or explosion.
- Do not heat batteries.
- Do not crush, puncture, dismantle or otherwise damage batteries.
- Do not charge non-rechargeable batteries.
- Keep batteries out of reach of small children.
