Health and Safety at Work Act

The primary UK legislation requiring employers to ensure the health, safety and welfare of employees and others, and employees to take reasonable care and cooperate.

PUWER 1998

Provision and Use of Work Equipment Regulations: work equipment must be suitable, maintained, inspected, and used only by trained and competent persons.

RIDDOR dangerous occurrence

A reportable incident such as an overturn of a dumper, failure of lifting equipment, or collapse of scaffolding; must be reported to the HSE.

Hierarchy of control

The order of risk control: eliminate, substitute, engineering controls, administrative controls, then PPE as the last resort.

WBV exposure action value

Whole-body vibration daily exposure action value is 0.5 m/s² A(8); at or above this, employers must take action to reduce exposure.

Noise upper action value

85 dB(A) daily exposure; hearing protection zones must be marked and PPE provided on request; hearing checks offered.

Site induction

Site-specific briefing covering layout, hazards, rules, emergency procedures and welfare; must be completed before starting work.

Minimum dumper PPE

Hard hat, safety boots, high-visibility vest or jacket, and eye protection when required; hearing protection in posted zones.

ROPS and FOPS

Roll-over and falling-object protective structures; they protect the operator and must never be modified or welded without manufacturer approval.

Articulation joint

The hydraulic pivot between front and rear chassis that allows tight turning; it increases swept path and tail swing.

Payload plate

A plate showing maximum safe payload and gross vehicle weight; exceeding it affects stability and braking.

Daily walk-around check

Pre-start inspection of leaks, tyres, wheel nuts, hoses, guards, fluids, lights, horn, seat belt and parking brake; recorded and signed.

Hydraulic leak danger

Hydraulic fluid under pressure can penetrate skin; never search for leaks with hands; use cardboard or a mirror.

Defect reporting procedure

Report any safety-related defect to the supervisor immediately, record it in the defect log, and do not operate until repaired or declared safe.

Machine isolation

Before maintenance: key off, battery isolator off, parking brake on, and controls in neutral to prevent unexpected movement.

Tyre inflation safety

Use a restraining device or cage when inflating; never weld or heat wheel rims; follow manufacturer's pressure.

Safe start sequence

Seat belt on, parking brake applied, controls in neutral, area clear, then start; check warning lights extinguish.

Off-tracking

The rear wheels of an articulated dumper track inside the front wheels when turning; allow for this to avoid hitting obstacles.

Emergency brake use

If service brakes fail, use the emergency brake and steer to a safe stop; do not pump the brake pedal.

Loading the dumper

Position so the loader can load evenly over the rear; do not exceed payload; keep the operator in the cab or clear.

Tipping procedure

Stop on level ground, apply parking brake, check behind and above, then raise and tip; lower skip before moving.

Stockpile edge danger

The edge can collapse under the machine's weight; stay back, use a spotter or marker, and never tip over the edge.

Maximum slope gradient

The safe gradient is given in the operator's manual; typically do not exceed 10–15% for articulated dumpers, less on wet ground.

Side slope risk

Travelling across a slope increases roll-over risk; drive straight up or down and keep the load low.

Overhead line clearance

Keep a minimum safe distance (e.g., 10 m) from overhead power lines unless confirmed isolated; never tip under lines.

Pedestrian segregation

Separate pedestrians and vehicles using barriers, walkways and crossings; where not possible, use speed limits and banksmen.

Banksman signals

Agree signals before starting; stop if communication is lost; the banksman must be visible to the operator at all times.

Site speed limit

Typically 10 mph (16 km/h) or lower; obey posted limits and reduce further in congested areas or near pedestrians.

Shutdown sequence

Park brake on, controls in neutral, skip lowered, engine off, key removed, and machine isolated (battery isolator off if fitted).

Parking on a slope

Avoid if possible; if unavoidable, apply parking brake, chock the wheels, and lower the skip fully.

Refuelling safety

Engine off, no smoking, use a funnel, clean up spills, and ensure a fire extinguisher is nearby.

End-of-shift handover

Report defects, incidents or near misses to the supervisor and next operator; complete the handover book and secure the machine.
