Electrical Fire Safety and Protection Quiz Practice…

Q: Which type of fire extinguisher is specifically designated for use on electrical fires?

Class C — Class C fire extinguishers are designed specifically for fires involving energized electrical equipment.

Q: Why is water dangerous to use on an electrical fire?

Water is a conductor of electricity and can cause shock — Water conducts electricity, which can lead to electrocution if the circuit is still energized.

Q: What is the primary function of a GFCI (Ground Fault Circuit Interrupter)?

To cut power instantly if current leakage is detected — GFCIs monitor current imbalance between hot and neutral wires and trip the circuit if leakage is detected.

Q: What is a common sign of a potential electrical fire caused by loose wiring?

Flickering lights accompanied by a burning odor — Flickering lights combined with a burning smell often indicate loose connections or arcing, which are high-risk fire indicators.

Q: Which of the following is considered a dangerous practice regarding electrical cords?

Running power cords under rugs or carpets — Running cords under carpets prevents heat dissipation and hides potential damage, significantly increasing fire risk.

Q: What should be the first action taken if an electrical fire starts?

Alert everyone nearby and disconnect power if safe — The safety of personnel is the priority; clearing the area and removing the energy source is standard safety protocol.

Q: What is a major cause of electrical fires related to outlet usage?

Overloading circuits with too many devices — Overloading circuits causes wires to overheat beyond their rated capacity, melting insulation and igniting surrounding materials.

Q: Why is it unsafe to replace a fuse with one of a higher amp rating?

It allows more current to flow than the wiring can safely handle — Fuses are sized to protect the wiring. A higher-rated fuse prevents the circuit from breaking before the wires themselves overheat.

Q: Which of the following is a symptom of a scorched outlet?

Discoloration or brown marks around the outlet faceplate — Scorching or discoloration on an outlet is a clear sign of localized heating and electrical arcing, requiring immediate attention.

Q: How often should smoke alarm batteries generally be replaced, according to standard safety tips?

Every year — Yearly replacement is a standard preventative maintenance step to ensure the reliability of life-safety systems.
