What this covers

Sample questions

You need to walk past an excavator that is working. What should you do?

  1. Wait until the operator has seen you and signals you past
  2. Walk quickly behind the machine while it is slewing
  3. Pass close to the tracks, where the operator can hear you
  4. Wave your arms and keep walking at a steady pace
Show the answer

A. Wait until the operator has seen you and signals you past

Operators have large blind spots, so you should stay outside the working zone until the operator has acknowledged you and stopped the machine. Passing behind a slewing excavator puts you in the crush zone of the counterweight.

What is the most effective way of reducing the risk from reversing vehicles on site?

  1. Fit every vehicle on the site with a flashing amber beacon
  2. Tell drivers to sound the horn before they start to reverse
  3. Ask pedestrians to keep a look-out for vehicles reversing
  4. Plan the layout with a one-way system so reversing is avoided
Show the answer

D. Plan the layout with a one-way system so reversing is avoided

Designing out reversing with one-way systems and turning areas removes the hazard. Where reversing cannot be avoided, a trained vehicle marshal, cameras and alarms are used, but these are lower in the hierarchy.

Who may operate an item of plant such as a forward-tipping dumper on site?

  1. Anyone who holds a full car driving licence
  2. Anyone who has watched it being operated
  3. Someone trained, competent and authorised for it
  4. Someone over 21 with a supervisor's consent
Show the answer

C. Someone trained, competent and authorised for it

Plant may be operated only by people who have been trained and assessed as competent on that type of machine and authorised by the employer. A car licence shows nothing about competence on site plant.
