    Right Answer: C Do not adjust tools which could still be live or operate.
  11. Question 8.11 An electric drill is to be used. Before use, who should carry out a check on the tool? A: Storeman B: Electrician C: Foreman D: User
    Right Answer: D The user needs to be satisfied that the tool has no obvious defect before use
  12. Question 8.12 What action should you take if an electric drill cuts out while you are using it? A: Shake it about a bit B: Put it back into the tool box C: Switch the power off and on D: Remove it from use and tell your supervisor
    Right Answer: D The drill may be faulty. If so, tell your supervisor and remove the drill from service.
  13. Question 8.13 If an electric drill gives off blue smoke from the motor, you should: A: pour water over it B: use a CO2 extinguisher C: switch it off and report it D: stop work for 30 minutes
    Right Answer: C Defective electric hand tools must not be used. Stop what you are doing and inform your supervisor.
  14. Question 8.14 How often should user (visual) checks be carried out on portable electrical equipment? A: Every time you use it B: Every day C: Once a week D: At least once a year
    Right Answer: A All items of portable electrical equipment should bevisually checked for safety by the user before being putinto use.
  15. Question 8.15 What is the preferred nominal voltage for portable hand lamps for general use on construction sites? A: 110 volts B: 150 volts C: 230 volts D: 400 volts
    Right Answer: A 110 volt reduced low voltage systems are strongly preferred for the supply to such equipment.
  16. Question 8.16 What is the preferred nominal voltage for portable hand tools on construction sites? A: 12 volts B: 24 volts C: 110 volts D: 230 volts
    Right Answer: C 110 volt reduced low voltage systems are strongly preferred for the supply to such equipment.
  17. Question 8.17 What is the preferred nominal voltage for local lighting up to 2 kW on construction sites? A: 55 volts B: 110 volts C: 400 volts D: 230 volts
    Right Answer: B 110 volt reduced low voltage systems are stronglypreferred for the supply to such equipment.
  18. Question 8.18 What is the recommended maximum voltage for portable hand lamps when working in confined or damp locations? A: 50 volts B: 110 volts C: 230 volts D: 400 volts
    Right Answer: A Where the environment is damp, or restricting andconductive, the magnitude of any electric shock will behigher than under normal conditions. Hand lamps in such locations should therefore be supplied from a SELV(separated extra-low voltage) system, i.e. having a maximum voltage of 50 volts and which is electricallyseparated from earth.
  19. Question 8.19 If you only have a mains voltage (230 V) hand drill and you want to use it on a construction site which only has yellow (110 V) socket-outlets, what should you do? A: Use a transformer to boost the voltage B: Cut the plug off and fit a yellow one instead C: Obtain a 110 V drill or a cordless one for the work D: Make up an extension cable with a yellow plug on one end and a standard socket on the other end
    Right Answer: C Electrical equipment must not be modified or operated at voltages other than their design voltage.
  20. Question 8.20 What is most commonly used to reduce 230 volts to 110 volts on site? A: Residual current device B: Transformer C: Circuit breaker D: Step-down generator
    Right Answer: B A transformer, usually coloured yellow, will transform 230volts (mains voltage) down to a relatively safe 110 volts.
  21. Question 8.21 When using an extension cable reel, which of the following statements is correct? A: Leave as much as possible coiled up on the reel B: Uncoil it fully every time C: Do not exceed the reeled or unreeled rating as appropriate D: Only uncoil what you need
    Right Answer: C The rating of a partially unreeled extension cable is muchlower than when fully unreeled. Overheating of the cablewill occur if the rating is exceeded. Care should also betaken to prevent extension cables becoming a tripping hazard.
  22. Question 8.22 If an extension cable is to be run across a site road, what action should you take? A: Throw wooden boards over it B: Place a rubber protection ramp over it and put up a sign stating ’Ramp Ahead’ C: Don’t do anything to protect the cable D: Lay the cable over wooden boards
    Right Answer: B It is essential that the cable is protected from damage caused by passing traffic. A sign will warn road traffic of the ramp.
  23. Question 8.23 To operate a powered hand tool you must be: A: 16 years old or over B: 18 years old or over C: 21 years old or over D: Trained and competent
    Right Answer: D There are no general age restrictions in legislation relating to the use of work equipment. Any person using work equipment, however, must be competent to do so, which will require initial and refresher training.
  24. Question 8.24 If you are about to use a power tool and discover the guard is missing, you should: A: Make up a temporary guard yourself B: Use the tool but try to work quickly C: Not use the tool until a proper guard has been fitted D: Use the tool but work carefully and slowly
    Right Answer: C Visual checks should be carried out before using equipment. Any faults should be reported immediately and rectified before use
