A stylist plugs several hot styling tools into a single power strip that is already loaded with equipment from adjacent stations. What safety hazard does this practice create?
- AOverloading the circuit increases the risk of overheating and fire
- BNo real hazard exists since power strips are designed for multiple devices
- CThe only consequence is a tripped breaker, which poses no safety concern
- DThis is acceptable as long as the power strip has a surge protector
Show answer & explanationAnswer & explanation
Correct answer: A. Overloading the circuit increases the risk of overheating and fire
Plugging multiple high-wattage tools into a single power strip can overload the circuit, causing overheating of wires and connections, which is a recognized fire hazard. Cosmetologists should avoid daisy-chaining or overloading outlets with heat-producing equipment.
Why the other options are wrong
- B. Wrong—power strips have amperage limits that can be exceeded.
- C. Wrong—a tripped breaker is a symptom of a real overheating hazard, not harmless.
- D. Wrong—surge protectors guard against voltage spikes, not overloading from too many devices.
Electrical/Fire Safety
Overloading electrical circuits with too many devices, especially high-wattage tools, increases fire risk from overheating.
- Avoid daisy-chaining power strips
- Inspect cords for fraying regularly
- Keep flammables away from heat sources
- Keep fire extinguisher accessible
Memory trick: Overloaded outlet = too many plugs = spark and fire
