The Reversing Bay With No Banksman
You are driving a 6-tonne dumper in a busy materials yard. The route from the stockpile to the batching plant passes a corner where a site office blocks your view of a pedestrian walkway. On the gate you use there is a blue circular sign showing a hard hat and high-visibility vest, a red circular "no pedestrian access" sign, and a yellow triangular sign bearing a lightning-bolt symbol mounted above a row of goalposts about 5 m overhead. The yard is tight, so you must reverse about 25 m out of the loading bay. There is no banksman available until 10:00 and it is 09:40. It is raining and the wipers are working.
1. Explain what each of the three signs means and how it changes what you do.

Sign shape and colour carry the meaning, and each one adds a control.
- Blue circle (hard hat and hi-vis): a mandatory sign. You must wear both - and it is a reminder that others in the yard are required to, but not guaranteed to, be visible and protected. It does not mean pedestrians are safe around you.
- Red circle (no pedestrian access): a prohibition sign. Pedestrians are not permitted through that gate. That is a control that depends on people obeying it, so you still plan on the basis that someone may walk through, particularly at a blind corner.
- Yellow triangle (lightning bolt) above goalposts: a warning sign for overhead lines. The goalposts are the physical clearance limit. The warning applies whatever the skip is doing - most overhead line contacts on plant happen with a raised skip, tipper body or mast, not the cab.
Together: PPE on, treat the gate as a pedestrian risk you must still manage, and never raise the skip or work under the lines without the agreed clearance and permission.
2. How do you manage the 25 m reverse with no banksman until 10:00?
Read the worked answer
You either create a controlled reverse or you wait or reconfigure - you do not reverse 25 m blind because the clock says so.
Options, in order:
- Avoid the reverse. Can the load be dropped so you drive out forward? Can the bay be re-planned, or the machine turned in a clear part of the yard? Forward travel is always preferable.
- Create a banksman. A trained, authorised person - not just whoever is nearest - who stands in clear view, on firm ground, out of the path of the machine, with agreed signals. If one cannot be found, that is a management decision to make, not a gap for you to fill with hope.
- Wait until 10:00 if the reverse cannot be made safe. Explain why: a 25 m reverse past a blind corner where a site office blocks the view of a pedestrian walkway.
If it must be done, the minimum: walk the route first and clear it, mirrors set and clean, windows clear, horn sounded, low speed, hazard lights, stop immediately if you lose sight of your rear or anyone appears. Rain adds poor visibility and longer stopping distances to the list.
3. Suppose the raised skip touches the overhead line. What do you do?
Read the worked answer
Assume the machine and the ground around it are live. Do not become the path to earth.
- Stay in the cab. The cab offers some protection; stepping out while touching the machine and the ground makes you the conductor.
- Warn others to stay well back and not to touch the machine or anything in contact with it.
- Use the horn, radio or phone to raise the alarm and get the line isolated by the electricity supplier or site authorised person.
- Lower the skip only if it can be done safely and only on instruction; moving the machine off the line is a decision for the authorised person.
- If fire forces you out, jump clear with feet together and shuffle or hop away without touching the machine and ground at the same time.
The prevention is the point: check the goalposts and clearance before raising the skip anywhere near the line, and treat the warning sign as applying to every part of the machine, not just the cab.
