Questions With All Correct Answers
Dumpers size - Answers -✔✔ Dumpers are available in many sizes, when planning
work the size of the dumper needs to be taken into account. Using the wrong size
dumper can cause problems because a small dumper can reduce hire costs however it
can often be overloaded causing an incident because overloading affects the dumpers
stability.
Dumper too big - Answers -✔✔ If dumper is too big or working in a restricted area
mainly on smaller sites, the operator may need to do additional manoeuvring, this can
damage ground and may cause the dumper to strike other machines or structures.
Dumpers and terrain - Answers -✔✔ As dumpers transport materials over a wide variety
of terrain (land) including soft ground, inclines and rough terrain. This can present
hazards for the dumper operator. Work sites need to be planned out so that travel
routes from the loading point to tipping point minimise the need to travel on poor terrain
or inclines.
Planning of travel routes - Answers -✔✔ Planning of travel routes also needs to take
into account pedestrians, who will need to have a separate travel route to avoid a
collision.
Planning of work - Answers -✔✔ Planning should also take into account changes to
ground, for example wet weather may cause travel ground to be slippery and can turn
firm ground into soft ground.
Travel route and embankments - Answers -✔✔ If travel route is close to the edge of an
embankment a barrier should be provided so the dumper does not travel over the edge.
Barrier systems - Answers -✔✔ Tipping loads into a trench or over an edge is a hazard
for dumper operators. Machines can fall into open trenches when a barrier system (stop
blocks) has not been used. When stop blocks or an earth berm are used when tipping
over the edge operators should not rely on them to stop the dumper because they only
minimise the risk of the dumper going over the edge.
Who do dumper operators work with? - Answers -✔✔ Dumpers are usually loaded by
another machine so dumper operators need to work with other plant operators as well
as general site operatives when travelling with and unloading materials.
Skips - Answers -✔✔ The dumper operator needs to insure that the skip is not
overloaded by the loading machine. Otherwise safety issues can occur. For example
the dumper operator could have restricted visibility in front of the machine
