Dumper Safety

Site dumpers are involved in a significant number of plant-related fatalities on UK construction sites each year.
Overturning is the most common cause of dumper fatalities — caused by overloading, speeding, soft ground, and slopes.
All dumper operators must hold a valid CPCS or NPORS card for the specific dumper category being operated.
The seat belt must be worn at all times — in a rollover, an unbelted operator is thrown from the cab and crushed.
Forward tipping dumpers have a high centre of gravity when loaded, making them unstable on slopes and uneven ground.
Travel with the skip raised obscures forward vision and raises the centre of gravity, dramatically increasing overturn risk.
Dumpers must never be used to carry passengers — there is no safe location for a second person on a dumper.
Pre-use checks must cover brakes, steering, tyres, lights, seat belt, skip mechanism, and all safety systems daily.
Haul routes must be maintained with a suitable surface, adequate width, safe gradients, and turning areas.
Reversing dumpers require a banksman in areas where pedestrians may be present — blind spots are significant.

Prevent overturn	Dumper rollovers crush and kill operators — wearing the seat belt, managing speed, and avoiding slopes save lives.
Visibility	Forward tipping dumpers obscure the driver's view when loaded — travelling with a raised skip causes collisions and struck-by injuries.
No passengers	Dumpers are designed for one operator only — passengers have been killed falling from dumpers in transit.

Do

Don't

Hold a valid CPCS or NPORS dumper card before operating any site dumper.
Wear the seat belt at all times while operating the dumper.
Complete the daily pre-use check and record the results before starting work.
Travel with the skip in the lowered position to maintain stability and visibility.
Reduce speed on slopes, bends, and uneven ground to prevent overturning.
Use a banksman when reversing near pedestrians or in congested areas.
Follow designated haul routes and obey site speed limits at all times.
Report any defects in brakes, steering, tyres, or the skip mechanism immediately.
Tip loads away from excavation edges using stop blocks to prevent overrun.
Switch off the engine and apply the handbrake before leaving the cab.

DON'T operate a dumper without a valid CPCS or NPORS competency card.
DON'T drive without your seat belt fastened — rollovers happen without warning.
DON'T skip the daily pre-use inspection — it catches faults before they cause incidents.
DON'T travel with the skip raised — it blocks your view and raises the centre of gravity.
DON'T speed on slopes or rough ground — excessive speed is the main cause of overturns.
DON'T reverse without a banksman in areas where pedestrians are present.
DON'T take shortcuts off the designated haul routes across the site.
DON'T use a dumper with defective brakes, steering, or non-functioning seat belt.
DON'T tip loads near unprotected excavation edges without stop blocks in place.
DON'T carry passengers on the dumper under any circumstances — it is for one operator only.
