What action should you take if a power tool begins sparking or emitting smoke during use?
Answer: Immediately switch it off, unplug it, and remove it from service for inspection
Sparking or smoke indicates internal electrical failure; continuing use risks fire or electrocution, so the tool must be shut off and removed immediately.
What type of fire extinguisher is approved for use on an electrical fire involving live equipment?
Answer: CO2 (carbon dioxide) extinguisher
CO2 extinguishers are non-conductive and leave no residue, making them safe and effective for electrical fires on live equipment.
How should extension cords be managed on a construction site to prevent trip hazards and damage?
Answer: Route them overhead or along walls secured with cable clips, keeping walkways clear
Routing extension cords overhead or along walls eliminates trip hazards and protects them from being run over by vehicles or foot traffic.
What is the correct way to carry a power tool when moving between work locations on site?
Answer: Carry it by the handle with the trigger in the safe (off) position and any disc guard in place
Carrying a tool by its handle with guards in place and the trigger locked off prevents accidental activation and protects the tool and nearby workers.
Why must power tools only be used with extension cords of adequate current rating?
Answer: An undersized cord overheats, causing voltage drop, tool damage, and fire risk
When a tool draws more current than an extension cord is rated for, the cord heats up, insulation degrades, and fire or electrocution can result.
Before using a voltage tester or multimeter on site, what must be verified to ensure accurate and safe results?
Answer: That the meter's CAT rating is appropriate for the voltage level being tested, and it has been recently calibrated
A meter's CAT (category) rating must match or exceed the voltage environment to prevent meter explosion from transient overvoltages; calibration ensures accurate readings.
