CSCS Site Dumper flashcards

34 cards. Read the term and the definition here. The deck at the top of this page is optional.

Reasonably practicable

A dutyholder must weigh the risk against the cost in time, money and effort of controlling it; gross disproportion between cost and risk can justify not doing more.

RIDDOR over-seven-day injury

An injury that keeps a worker off normal duties for more than seven consecutive days, not counting the day of the accident, must be reported to the enforcing authority.

Accident book threshold

Injuries keeping a worker off normal duties for more than three days are recorded in the site accident book, but are not reportable to the HSE.

Hierarchy of control

The order of risk control: eliminate the hazard, substitute it, apply engineering controls, then administrative controls, with personal protective equipment last.

Mandatory sign appearance

A blue circle with a white symbol tells you an action must be taken, such as wearing head protection or a safety harness in that area.

Prohibition sign appearance

A red circle with a diagonal red bar over a black symbol on white shows something is forbidden, such as smoking or unauthorised entry.

Warning sign appearance

A yellow triangle with a black border and black symbol warns of a hazard ahead, such as deep excavation, overhead power lines or falling objects.

Near miss definition

An unplanned event that did not injure anyone or damage anything but had the potential to do so, so it is reported and investigated.

Competent person meaning

Someone with sufficient training, experience, knowledge and other qualities to identify risks and take appropriate action in the task assigned to them.

COSHH assessment purpose

It identifies hazardous substances on site, the health risk from exposure, and the controls needed, including ventilation, substitution, and suitable respiratory protection.

Site induction purpose

A briefing before starting work covering site rules, layout, emergency arrangements, first aid, welfare facilities and the specific hazards of that site.

Welfare facilities requirement

Sites must provide drinking water, washing facilities, sanitary conveniences, changing and drying rooms where needed, and a place to rest and eat meals.

Environmental spill response

Stop the source, contain the spill with a bund or absorbent, protect drains, report it, and dispose of contaminated material as hazardous waste.

PUWER inspection duty

Work equipment must be suitable, maintained, inspected at intervals set by risk assessment, and operated only by people who are trained and competent.

LOLER lifting threshold

Lifting equipment, including attachments used for lifting, must be thoroughly examined at least every six months, or twelve months for other lifting accessories.

Emergency assembly point

The designated place where personnel gather after an evacuation so a roll call can confirm everyone is accounted for and nobody re-enters.

Dumper pre-use check

A walk-round inspection at the start of each shift covering fluids, tyres, brakes, steering, horn, lights, seat belt, ROPS and visible leaks.

ROPS and FOPS

Roll-over and falling-object protective structures; they only protect the operator if the seat belt is worn and the structure is undamaged and unmodified.

Loaded skip height

When travelling, keep the skip low and the load central; a raised skip raises the centre of gravity and makes overturn far more likely.

Travelling on gradients

Climb and descend in the lowest suitable gear, keep the load uphill, avoid turning across a slope, and never freewheel downhill.

Banksman role

A trained signaller who guides the reversing or manoeuvring operator; the operator stops at once if the banksman is not clearly visible.

Tipping area preparation

Check the ground is level and firm, the edge has a stop block or berm, the area behind is clear, and no one is in the tip zone.

Tipping over an edge

Reverse squarely to the stop block, tip only when stationary, and never allow the skip to overhang an unprotected edge or excavation.

Passenger prohibition

A site dumper carries one operator unless a manufacturer-fitted second seat exists; riding in the skip risks fatal crushing during tipping.

Safe parking procedure

Lower the skip, set controls to neutral, apply the parking brake, remove the key, and chock the wheels when leaving a machine on a slope.

Refuelling precautions

Switch off the engine, allow it to cool, avoid smoking or naked flames, use a funnel, and clean up spills before restarting the machine.

Travel position of skip

Carry the skip low and trailing, with the load evenly distributed, so the machine stays stable and the operator keeps forward visibility.

Machine familiarisation

Site-specific instruction on the exact dumper's controls, capacity, load chart and site routes, given before the operator first uses it.

Dumper load capacity

The maximum rated payload shown on the machine plate; overloading raises the centre of gravity, overloads tyres and brakes, and increases overturn risk.

Wheel chock use

A wedge placed against a wheel to stop a parked machine rolling; required on gradients and whenever the parking brake alone may not hold.

Site traffic route rules

Pedestrians and dumpers are segregated by barriers and marked routes; the operator keeps to designated haul roads and obeys site speed limits.

Reversing visibility loss

If mirrors and direct vision do not give a clear view behind, the operator stops and uses a banksman rather than reversing blind.

Overhead power line rule

Keep the machine and raised skip well clear of overhead lines; if contact occurs, stay in the cab and warn others until the line is isolated.

Seat belt on dumpers

The seat belt keeps the operator inside the protective structure in an overturn; it must be worn whenever the machine is moving.
