Avoiding risks to yourself and others

What is the primary function of a transformer in the context of electrical tools used by carpenters and joiners?

• To increase the voltage from 110 V to 230 V

• To reduce the voltage from 230–240 V to 110 V

• To convert AC to DC

• To store electrical energy

Why is a 110 V supply recommended for use on construction sites and joinery workshops?

• It provides more power than 230 V

• It reduces the risk of death while still providing enough power to operate tools

• It is cheaper to produce

• It is the standard voltage for all electrical appliances

What is the purpose of a residual current device (RCD)?

• To increase the voltage supply

• To stop the supply of electricity when a fault is detected

• To convert DC to AC

• To store electrical energy for later use

What should be checked first before inspecting a power tool for wear and tear?

• The sharpness of the tooling

• The PAT certificate or label

• The connection to the power supply

• The on/off switches

What is the recommended frequency for PAT testing power tools used on construction sites?

• Every 6 months

• Every 3 months

• Every year

• Every month

What should be done if a power tool fails the PAT test?

• Continue using it until it is repaired

• Mark it for repair or scrap it immediately

• Use it only for low-risk tasks

• Reduce its voltage supply

What is the main reason for using different-shaped plugs and sockets for construction tools compared to domestic ones?

• To make them more aesthetically pleasing

• To keep moisture and dirt out of the connection

• To reduce the cost of production

• To increase the voltage supply

What should be done if a power tool's PAT certificate is not in date?

• Continue using the tool

• Stop work and report the tool to your supervisor

• Use the tool only for non-electrical tasks

• Test the tool yourself

What is the purpose of keeping the transformer unit near the 240 V supply?

• To increase the length of the high voltage lead

• To reduce the risk of death or serious injury

• To make it easier to access

• To improve the efficiency of the transformer

What should be checked on the body of a power tool during a visual inspection?

• The colour of the tool

• The presence of any cracks or missing parts

• The weight of the tool

• The length of the power cable
