CSCS Tools and Equipment Safety 2

Question 1

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

Accepted Answer

To cut off the electricity supply quickly if a fault occurs

Answer

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

Question 2

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

Accepted Answer

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

Answer

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.

Question 3

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

Accepted Answer

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

Answer

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

Question 4

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

Accepted Answer

CO2 (carbon dioxide) extinguisher

Answer

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

Question 5

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

Accepted Answer

Tag it out of service and report it to the supervisor

Answer

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.
