Tools and Equipment Safety Flashcards

What is the main purpose of a residual current device (RCD) used with electrical tools?

Answer: To cut off the electricity supply quickly if a fault occurs

An RCD rapidly disconnects the power supply when it detects a leakage current, protecting users from electric shock.

When should you stop using a ladder as a work platform and use scaffolding instead?

Answer: When the work takes longer than 30 minutes or both hands are needed

Ladders are only suitable for short-duration, light-duty tasks; if the job requires both hands or takes more than 30 minutes, a scaffold or working platform should be used.

What does a color-coded inspection tag on a tool or piece of equipment indicate?

Answer: That the tool has been inspected and is safe to use within a specific period

Color-coded inspection tags show the date of the last safety inspection and confirm the equipment is approved for use during the relevant period.

Which type of fire extinguisher should be used on an electrical equipment fire?

Answer: CO2 (carbon dioxide) extinguisher

CO2 extinguishers are safe to use on electrical fires because they do not conduct electricity and leave no residue that could cause further damage.

What is the correct procedure when a tool breaks during use on site?

Answer: Tag it out of service and report it to the supervisor

A broken tool must be taken out of service, clearly tagged or removed from the work area, and reported so it can be properly repaired or replaced.

Why should compressed air never be used to clean dust off clothing or skin?

Answer: Because it can force air into the body causing serious injury or death

Compressed air directed at the body can penetrate the skin or enter body openings, causing an air embolism or other life-threatening injuries.
