ECS Electrical Tools and Equipment Safety 3

Question 1

What action should you take if a power tool begins sparking or emitting smoke during use?

Accepted Answer

Immediately switch it off, unplug it, and remove it from service for inspection

Answer

Sparking or smoke indicates internal electrical failure; continuing use risks fire or electrocution, so the tool must be shut off and removed immediately.

Question 2

What type of fire extinguisher is approved for use on an electrical fire involving live equipment?

Accepted Answer

CO2 (carbon dioxide) extinguisher

Answer

CO2 extinguishers are non-conductive and leave no residue, making them safe and effective for electrical fires on live equipment.

Question 3

How should extension cords be managed on a construction site to prevent trip hazards and damage?

Accepted Answer

Route them overhead or along walls secured with cable clips, keeping walkways clear

Answer

Routing extension cords overhead or along walls eliminates trip hazards and protects them from being run over by vehicles or foot traffic.

Question 4

What is the correct way to carry a power tool when moving between work locations on site?

Accepted Answer

Carry it by the handle with the trigger in the safe (off) position and any disc guard in place

Answer

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.

Question 5

Why must power tools only be used with extension cords of adequate current rating?

Accepted Answer

An undersized cord overheats, causing voltage drop, tool damage, and fire risk

Answer

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.
