32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Reasonably practicable
- A legal test balancing the risk against the cost, time and difficulty of controlling it; used in the Health and Safety at Work etc. Act 1974 for employer duties.
- PUWER 1998
- Regulations requiring work equipment such as excavators to be suitable, maintained, inspected and used only by competent persons, with adequate information and training provided.
- LOLER examination interval
- Lifting equipment and accessories require thorough examination at intervals not exceeding six months, or twelve months for equipment not used for lifting people.
- COSHH assessment
- A recorded assessment of hazardous substances such as diesel, hydraulic oil and silica dust, identifying exposure routes and the controls needed before work begins.
- Waste duty of care
- The legal duty to store, transfer and dispose of controlled waste such as used oil and filters only through authorised carriers with correct documentation.
- Risk assessment five steps
- Identify hazards, decide who may be harmed and how, evaluate risks and controls, record findings, and review and update the assessment as work changes.
- Hierarchy of control
- The order of risk control: eliminate, substitute, engineering controls, administrative controls, and personal protective equipment as the last resort.
- Slew zone crush hazard
- The area swept by the rotating upper structure and counterweight; pedestrians must be excluded because the operator cannot see the whole area from the cab.
- Near-miss reporting
- Recording events that could have caused harm but did not; these are leading indicators used to correct hazards before an injury occurs.
- Prohibition sign
- A red circle with a diagonal bar indicating an action that must not be taken, such as no unauthorised entry to a plant operating area.
- Mandatory sign
- A blue circular sign indicating an action that must be taken, such as wearing hearing protection or a safety helmet in a designated area.
- Signaller duties
- A competent person who directs machine movement using agreed hand signals or radio when the operator's view is obstructed, and who stays in a safe position.
- Upper action value noise
- The daily noise exposure level of 85 dB(A) at which hearing protection must be provided and used, and hearing protection zones marked.
- ROPS and FOPS
- Roll-over and falling-object protective structures fitted to the cab; they protect the operator only if the seat belt is worn and the structure is undamaged.
- ISO control pattern
- The excavator joystick layout where the left lever controls slew and dipper arm and the right lever controls boom and bucket.
- Hydraulic lockout lever
- A lever that isolates the pilot control circuit so that joystick movement cannot operate the machine, used before leaving the cab.
- Load moment indicator
- An instrument that warns the operator when the machine approaches its rated capacity for the current radius, height and attachment configuration.
- Quick coupler check
- A visual and functional check that the locking pin is fully engaged after changing an attachment, because coupler failure can drop the bucket unexpectedly.
- Pre-use walk-around
- A visual inspection of the machine before starting, covering leaks, structural cracks, track condition, guards, fluid levels and safety devices.
- Defect tagging
- The process of taking a defective machine out of service, attaching a clear warning tag and isolating it until a competent person repairs it.
- Hydraulic injection injury
- A pinhole hydraulic leak can inject fluid through the skin, causing serious tissue damage; it is a medical emergency requiring immediate hospital treatment.
- Track tension check
- Measuring the sag on the longest run of the track against the manufacturer's specification; over-tension damages bearings and under-tension causes derailment.
- Centre of gravity rule
- A machine remains stable only while its combined centre of gravity stays within the support base formed by the tracks or wheels and outriggers.
- Rated capacity
- The maximum load stated in the load chart for a given radius and height; it decreases as radius increases and assumes level, firm ground.
- Slope travel rule
- Travel with the heavier end of the machine uphill, keep the bucket low, and avoid slewing or lifting while on a gradient.
- Ground bearing pressure
- The load per unit area imposed by the machine on the ground; it increases with weight, load and dynamic forces and must be checked on soft or backfilled ground.
- Cable avoidance tool
- A device used before excavation to detect buried metallic services; it must be used with service drawings and confirmed by hand-dug trial holes.
- Excavation surcharge
- Load added at the top of an excavation by spoil, materials or machines, which increases the risk of side collapse and must be kept back from the edge.
- Overhead line clearance
- The minimum safe distance from live overhead lines specified for the line voltage; barriers or goalposts mark the limit and lines are treated as live.
- Lifting with an excavator
- A planned lift using certified lifting points and accessories, a load chart or rated capacity indicator, and no movement of the load over people.
- Machine shutdown sequence
- Park on firm level ground, lower attachments, neutralise controls, engage lockout and parking brake, cool the engine, then stop and remove the key.
- Refuelling precautions
- Engine off, no ignition sources, bonded nozzle, drip trays in place and spill kit available; spilled fuel and absorbents are controlled waste.
