CSCS Articulated Dumper cheat sheet

Health and Safety at Work etc. Act 1974: employers must ensure safe plant and systems; employees must take reasonable care of themselves and others and cooperate with the employer.

Provision and Use of Work Equipment Regulations 1998 (PUWER): work equipment must be suitable, maintained in efficient working order, inspected where exposure to risk, and operated only by trained and competent persons.

Lifting Operations and Lifting Equipment Regulations 1998 (LOLER) apply to lifting accessories and attachments; a dumper used for lifting (e.g., with a crane hook) must have a SWL marked and be thoroughly examined.

Management of Health and Safety at Work Regulations 1999: suitable and sufficient risk assessments, competent persons appointed, and co-operation between employers sharing a site.

Construction (Design and Management) Regulations 2015: the principal contractor controls the construction phase plan, site induction, and traffic management; the operator must follow the plan and report hazards.

Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2013 (RIDDOR): dangerous occurrences include overturning of a dumper, failure of lifting equipment, and collapse of a scaffold; report to HSE.

Operator responsibilities: hold the correct category of competence card, operate only machines they are trained on, carry out pre-use checks, report defects, and never operate under the influence of drugs or alcohol.

Site speed limits and traffic rules are enforceable instructions; failing to comply can be a breach of site rules and, under the Health and Safety at Work Act, a failure to cooperate with the employer.

Hierarchy of control: eliminate, substitute, engineering controls (e.g., reversing cameras, segregation), administrative controls (e.g., speed limits, one-way systems), then PPE as the last resort.

Whole-body vibration (WBV) exposure action value = 0.5 m/s² A(8); exposure limit value = 1.15 m/s² A(8). Report symptoms (back pain, numbness) and keep exposure records.

Hand-arm vibration (HAV) exposure action value = 2.5 m/s² A(8); limit value = 5 m/s² A(8). Use low-vibration tools and keep hands warm.

Noise: lower exposure action value = 80 dB(A) daily; upper = 85 dB(A). At 85 dB(A) hearing protection zones must be marked and PPE provided on request.

Manual handling: assess load, environment, and individual capacity; use mechanical aids or team lifts for heavy or awkward items; avoid twisting under load.

Site induction must cover site rules, emergency procedures, first aid, fire points, traffic routes, and the location of welfare facilities; refresher induction required after absence or site changes.

Emergency response: know the site emergency number, muster point, first-aider locations, and how to isolate the machine (key off, park brake on, attachment lowered) before leaving it.

Fatigue and drugs/alcohol: report medication that may cause drowsiness; operators must not operate machinery while impaired; random testing may apply on site.

Minimum site PPE for dumper operation: hard hat, safety boots with ankle support, high-visibility vest or jacket (Class 2 or 3 as specified), and eye protection when required.

Hearing protection is mandatory in posted hearing protection zones (typically ≥85 dB(A)); use earmuffs or plugs with the correct SNR for the noise level.

Dust: use RPE (e.g., FFP3) when exposed to silica dust from cutting or dry sweeping; water suppression reduces airborne dust.

Gloves must not interfere with controls; avoid loose clothing, scarves, or jewellery that could catch on levers or the steering wheel.

Seat belt must be worn whenever the machine is moving; ROPS (roll-over protective structure) and seat belt together protect in a roll-over.

Site induction is site-specific and must be completed before starting work; it covers layout, hazards, rules, and emergency arrangements; keep the card or sticker visible.

PPE is the last line of defence; it does not replace engineering controls, traffic segregation, or safe systems of work.

Inspect PPE before use: cracked hard hat, damaged harness, or worn boot soles must be replaced; report defects to the supervisor.

Articulated steering: a hydraulic ram pivots the front and rear chassis; the articulation joint allows tight turns but increases the swept path and tail swing.

Main controls: steering wheel, accelerator, brake pedal, forward/neutral/reverse shuttle or lever, parking brake, and dump lever (raise/lower and tip).

ROPS/FOPS: roll-over and falling-object protective structures protect the operator; never modify or weld them without manufacturer approval.

Skip/body: the front-tipping skip is raised by hydraulic rams; check the body prop or safety strut is in place before working under a raised skip.

Payload plate: shows maximum safe payload and gross vehicle weight; never exceed the rated payload; overloading affects stability and braking.

Instruments and warning lights: engine oil pressure, coolant temperature, battery charge, parking brake, and articulation lock warning; stop and investigate any red warning.

Articulation lock: some machines have a lock pin for transport or maintenance; ensure it is removed before operating and stowed correctly.

Daily checks include engine oil, coolant, hydraulic oil, fuel, tyre condition and pressure, lights, horn, seat belt, and articulation joint for wear or looseness.

Walk-around inspection: check for leaks, damaged tyres, loose wheel nuts, cracked hoses, missing guards, and debris around the machine.

Fluid levels: engine oil, coolant, hydraulic oil, and fuel; check with the machine on level ground and engine off; top up only with the correct specification.

Tyre check: correct pressure per manufacturer, no cuts or bulges, and tread depth adequate; dual tyres must be matched to avoid differential wear.

Safety devices: test horn, lights, beacon, reverse alarm, seat belt, and parking brake before moving; report any failure.

Operator station: adjust seat and mirrors, ensure pedals and levers are clean and free from mud, and check that the steering wheel turns freely.

Fluid leaks: hydraulic leaks under pressure can penetrate skin; never search for leaks with hands; use cardboard or a mirror.

Record the pre-start check on the daily inspection sheet; sign and date it; report defects immediately and do not operate a defective machine.

Before starting: ensure area is clear of people, apply parking brake, place controls in neutral, and start from the operator seat only.

Defect reporting: report any defect that affects safety to the supervisor immediately; record it in the defect log; do not operate until repaired or declared safe.

Maintenance must be carried out by competent persons; isolate the machine (key off, battery isolator off, park brake on) before maintenance.

Hydraulic systems: depressurise before disconnecting lines; use the correct fluid and filter; never mix hydraulic oils.

Tyres: inflate to manufacturer's pressure; use a restraining device or cage when inflating; never weld or heat wheel rims.

Lubrication: follow the service schedule; grease articulation pins, steering rams, and linkages at specified intervals.

Record keeping: daily checks, service records, and defect repairs must be documented; these records may be required by PUWER and for insurance.

After maintenance: remove tools, refit guards, check controls, and carry out a function test before returning to work.

Battery: handle with care; use PPE (gloves, eye protection); disconnect negative first and reconnect last; charge in a ventilated area.

Starting: seat belt on, parking brake applied, controls in neutral, area clear, then start; check instruments and warning lights extinguish.

Moving off: release parking brake only when ready; check mirrors and blind spots; sound horn if reversing or if visibility is restricted.

Articulated steering: the machine pivots at the centre; the rear wheels track inside the front wheels, so allow for off-tracking and tail swing when turning.

Speed: travel at a speed that allows stopping within the visible distance; reduce speed on slopes, rough ground, and near pedestrians.

Braking: use engine braking on downgrades; avoid riding the brakes; if brakes fail, use the emergency brake and steer to a safe stop.

Stopping: park on level ground, apply parking brake, lower skip, controls in neutral, engine off, remove key; chock wheels if on a slope.

Reversing: use mirrors and cameras; if visibility is obstructed, use a trained banksman; never reverse without checking behind.

Travelling on slopes: drive straight up or down where possible; avoid traversing; keep the load low; do not change gear on a slope if possible.

Loading: position the dumper so the loader can load evenly; do not exceed the payload plate; load over the rear, not the cab; keep the operator in the cab or clear.

Load distribution: keep the load centred and low; an uneven load shifts the centre of gravity and increases roll-over risk.

Hauling: keep the skip lowered while travelling; raised skips raise the centre of gravity and can contact overhead lines.

Discharging: stop on level ground, apply parking brake, check behind and above for people and obstacles, then raise and tip.

Stockpile edge: stay back from the edge; use a spotter or marker; the edge can collapse under the weight of the machine.

After tipping: lower the skip before moving; ensure the body is fully down and the warning light is off.

Overhead lines: keep a minimum safe distance (e.g., 10 m for overhead lines unless the line is confirmed isolated); never tip under lines.

Spillage: clean up spilled material; it can cause slips and affect other vehicles; report significant spillage.

Ground conditions: check for soft ground, voids, excavations, and buried services; use a banksman or probe if unsure; avoid edges of excavations.

Slope stability: maximum safe gradient is given in the operator's manual; typically do not exceed 10–15% for articulated dumpers; reduce further on wet or loose ground.

Travelling on slopes: drive straight up or down; avoid side slopes; keep the load low; engage four-wheel drive if fitted; do not turn on a slope.

Roll-over risk: raised skip, high speed on a turn, soft ground, and side slopes increase risk; wear the seat belt and keep the skip down.

Overhead hazards: power lines, bridges, and trees; check clearance height; do not raise the skip near lines.

Underground services: check for gas, water, and electricity; use a cable avoidance tool (CAT) and safe digging practices; report any strike immediately.

Weather: rain, ice, and wind affect stability and visibility; reduce speed and increase stopping distance; stop work if conditions become unsafe.

Site traffic: follow one-way systems, speed limits, and give way rules; never cut across another vehicle's path.

Segregation: pedestrians and vehicles must be separated by barriers, walkways, and crossing points; where segregation is not possible, use speed limits and banksmen.

Blind spots: articulated dumpers have large blind spots, especially at the rear and around the articulation; use mirrors, cameras, and a banksman when reversing.

Reversing: minimise reversing; use one-way systems and drive-through loading; if reversing is necessary, use a trained banksman and sound the horn.

Pedestrian awareness: make eye contact; never assume a pedestrian has seen you; stop if a pedestrian enters your path.

Site speed limits: typically 10 mph (16 km/h) or lower; obey posted limits and reduce further in congested areas.

Parking: park in designated areas, not on walkways or blocking access; apply parking brake, lower skip, remove key.

Communication: use radios or agreed signals with banksmen; agree signals before starting; stop if communication is lost.

Traffic management plan: know the routes, junctions, and priorities; report any near miss or collision immediately.

Park on level, firm ground; if unavoidable on a slope, chock the wheels and apply the parking brake; lower the skip fully.

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

Secure the machine: lock the cab, remove the key, and use steering lock if fitted; do not leave the machine unattended with the engine running.

End-of-shift checks: walk around the machine, check for leaks, damage, and loose items; report defects and complete the daily log.

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

Parking area: keep clear of traffic routes, excavations, and overhead lines; do not block emergency exits or fire points.

Handover: report any defects, incidents, or near misses to the supervisor and the next operator; complete the handover book.

Security: remove valuables; ensure the machine is secure to prevent unauthorised use; report any security concerns.
