Health and Safety at Work Act

The 1974 UK Act places general duties on employers to protect, so far as reasonably practicable, the health, safety and welfare of employees and others affected by work.

Employee duty under HASAWA

Employees must take reasonable care for their own and others' safety, cooperate with their employer on health and safety, and not intentionally interfere with or misuse safety provisions.

PUWER 1998

Provision and Use of Work Equipment Regulations require work equipment to be suitable, maintained in efficient working order, inspected where required, and used only by competent persons.

RIDDOR reporting

The Reporting of Injuries, Diseases and Dangerous Occurrences Regulations require specified work-related deaths, injuries, dangerous occurrences and occupational diseases to be reported to the enforcing authority.

Prohibition sign

A red circular sign with a diagonal slash indicates an action that must not be done, such as no smoking or no unauthorised access.

Warning sign

A yellow triangular sign warns of a hazard such as danger, deep excavation, moving plant, overhead lines or slippery ground.

Mandatory sign

A blue circular sign states an action that must be taken, such as wearing hearing protection, a safety helmet or high-visibility clothing.

Banksman hand signals

A banksman directs vehicle movements using agreed hand signals; the operator stops if signals are unclear, the banksman is not visible, or a person enters the danger area.

PPE last line

Personal protective equipment is a last line of defence and does not replace elimination, guarding, ventilation, safe systems of work or other engineering controls.

High-visibility clothing

High-visibility clothing makes workers conspicuous to plant operators; it must be clean, correctly fastened and replaced if damaged or badly soiled.

Site welfare facilities

Construction welfare facilities include toilets, washing facilities, drinking water, rest areas and accommodation for changing and storing clothing; they must be suitable and maintained.

Silica dust control

Silica dust from cutting or drilling can cause serious lung disease; controls include water suppression, extraction, enclosed cabs and suitable respiratory protective equipment.

ROPS and FOPS

ROPS is a roll-over protective structure; FOPS is falling-object protective structure. Both must be undamaged and not modified, and the seat belt must be worn where fitted.

Red warning lamp

A red warning lamp indicates a condition requiring immediate stop and investigation, such as low oil pressure, overheating, brake fault or charging system failure.

Rated load capacity

The maximum payload a dumper is designed to carry, stated on the machine plate or load chart; exceeding it reduces stability, braking and steering control.

Hour meter

An instrument that records machine running time in hours; it is used for scheduling maintenance, monitoring use and recording operating periods.

Daily pre-use check

A documented inspection before use covering tyres, fluid levels, leaks, brakes, steering, horn, lights, seat belt, ROPS/FOPS, skip pins and hoses.

Safety-critical defect

A fault affecting brakes, steering, tyres, ROPS/FOPS, seat belt or load security; the machine must be stopped, isolated and reported before further use.

Defect reporting procedure

Record the defect in the machine log, inform the supervisor, isolate or tag the machine if unsafe, and ensure repair and re-inspection before return to service.

Hot coolant cap

A pressurised coolant cap must not be opened while the engine is hot; allow cooling first because escaping steam and coolant can cause severe burns.

Travel with skip lowered

A loaded dumper should be travelled with the skip fully lowered and within payload; a raised skip raises the centre of gravity and increases overturn risk.

Loaded downhill travel

On a downhill gradient, select a low gear before the slope, keep the load low and use engine braking; avoid gear changes and sharp turns on the slope.

Side slope overturn risk

Travelling across a side slope shifts the centre of gravity sideways and increases roll-over risk; avoid side slopes or reduce speed and keep the load low.

Blind spot check

Before moving, check mirrors and all around the machine for people and obstructions; use the horn at blind corners and stop if visibility is restricted.

Payload limit

The maximum load stated for the dumper; exceeding it raises the centre of gravity and reduces braking, steering and stability, especially on slopes or soft ground.

Tip on level ground

Discharging is safest on firm, level ground with the parking brake applied; check behind and below for people, edges, services and obstructions before raising the skip.

Raised skip stability

Raising the skip lifts the load and centre of gravity; do not travel with the skip raised, and raise it only as far as needed on stable ground.

Tip edge exclusion

Keep the machine back from trench, embankment and tip edges; ground can collapse, so use stop blocks, a banksman or site-specified stand-off distances.

Shutdown sequence

Park on firm level ground, lower the skip, select neutral, apply the parking brake, switch off the engine, remove the key and secure the machine.

Parking on slope

If slope parking is unavoidable, apply the parking brake, chock the wheels and position the machine as site rules require; the parking brake alone may not hold.

Spill kit location

A spill kit contains absorbent materials and containment equipment for fuel, oil or hydraulic fluid leaks; know its location and use it before spills reach drains or watercourses.

Idling emission control

Unnecessary engine idling wastes fuel and produces exhaust emissions and noise; switch off the engine when safe and when the machine is not required.
