This is a requirement under r.14 of the EAW Regulations. However, it does not mean that live working is then 'safe'

What is the preferred nominal voltage for portable hand tools on construction sites?

110 volts

12 volts

230 volts

24 volts

Correct! Wrong!

110-volt reduced low voltage systems are strongly preferred for the supply of such equipment.

What is the most serious effect that electric shock can have if you come into contact with a live part?

The electric current can cause a slight tingling in the fingers

The electric current can cause burn marks on the fingers

The electric current can cause the finger muscles to twitch

Black

Blue

Red

Yellow

Correct! Wrong!

Explanation:
Yellow is the usual colour of cables, socket outlets, plugs, transformers etc which are used with a 110-volt supply.

What is most commonly used to reduce 230 volts to 110 volts on site?

Circuit breaker

Residual current device

Step-down generator

Transformer

Correct! Wrong!

Explanation:
A transformer, usually coloured yellow, will transform 230 volts (mains voltage) down to a relatively safe 110 volts.

With regard to the effect of electrical current on the human body, one of the following is correct:

A 3 amp fuse should prevent a person receiving a fatal electric shock

A 30mA Residual Current Device (RCD) should prevent a person from receiving a fatal electric shock.

A 5 amp rewireable fuse should prevent a person from receiving a fatal electric shock

A 6 amp circuit breaker should prevent a person receiving a fatal electric shock

Correct! Wrong!

Explanation:
An RCD is a mechanical switching device intended to cause the opening of the contacts when the residual current attains a given value under specified conditions.

What do the letters SWL stand for?

Safe working level

Safe working load

Satisfactory weight limit

Satisfactory working limit

Correct! Wrong!

Explanation:
Machinery and accessories for lifting loads should be clearly marked to indicate their safe working loads.

You have been asked to operate a cherry-picker (mobile elevated work platform) when it is very windy. What should your FIRST consideration be?

The capacity of the weakest individual

The sum of their individual capacities

Two-thirds the sum of their individual capacities

Correct! Wrong!

Explanation:
This is contained in HSE guidance on the Manual Handling Operations Regulations 1992.
