High Risk Work Licence - Reach Stacker (RS) flashcards

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

WHS Act primary duty

The PCBU must ensure the health and safety of workers and others so far as reasonably practicable, including providing safe plant and systems of work.

Notifiable incident reporting

Death, serious injury or illness, or dangerous incident must be reported to the regulator immediately after becoming aware; site must not be disturbed except to assist.

Hierarchy of control

Eliminate, substitute, isolate, engineering controls, administrative controls, PPE. Use highest level reasonably practicable to control risk.

Risk assessment formula

Risk = likelihood × consequence. Use a risk matrix to determine risk level and prioritise control measures.

Reach stacker tip-over hazards

Exceeding load chart, boom extension, uneven ground, soft ground, excessive speed, sudden movements, and wind can cause tip-over. Always operate within stability limits.

Load moment calculation

Load moment = load weight × horizontal distance from tipping line. The load chart accounts for this to prevent tipping.

Stability triangle

The centre of gravity must remain within the triangle formed by the centre of each tyre contact point. If it moves outside, the machine tips.

Load chart interpretation

Load chart shows maximum load at given boom length and angle. Capacity decreases as boom extends or angle lowers. Never exceed rated capacity.

Pre-operational inspection checklist

Check fluids, tyres, lights, horn, brakes, steering, boom, spreader, safety devices, leaks, and structural damage. Record results and report defects.

Defect reporting procedure

Report all defects immediately. Safety-critical defects require shutdown, tagging out, and repair by competent person before use.

Ground bearing capacity

The ability of ground to support reach stacker weight and load. Use mats or spreader plates on soft ground; avoid trenches and excavations.

Exclusion zone setup

Barricade area around operation including boom swing radius and load drop zone. Keep pedestrians out with barriers and signage.

Container spreader engagement

Ensure twist locks fully engage container corner castings. Visually confirm and test lift slightly before full lift.

Stacking containers safely

Stack squarely, within max height, on sound bottom container. Ensure containers are not damaged and are properly aligned.

Traveling with load

Keep load low and close to ground, tilt back slightly, travel slowly, avoid rough terrain and sudden movements.

Standard hand signals

Stop: palm down, arm extended. Raise: arm up, palm up. Lower: arm down, palm down. Extend: both arms out. Retract: both arms in.

Spotter communication

Only one designated spotter gives signals. Operator must obey stop signal from anyone. Maintain eye contact; stop if lost.

Pedestrian separation methods

Use physical barriers, marked walkways, exclusion zones, high-visibility clothing, and spotters to keep pedestrians away from reach stacker operation.

Emergency stop location

Know the location of the emergency stop button. Use it immediately in case of hazard to stop all machine functions.

Tip-over response

Stay in cabin, brace, do not jump. After machine stops, shut down, evacuate if safe, and report incident.

Fire response

Use dry chemical extinguisher for fuel/electrical fires. Evacuate if uncontrollable. Call emergency services.

Shutdown procedure

Park on level ground, lower attachment, apply park brake, neutral gear, engine off, remove key, lock cabin.

Post-operational inspection

After operation, check for leaks, damage, loose parts. Report defects. Clean machine and complete logbook.

Parking on slope

Avoid parking on slopes. If necessary, chock wheels, apply park brake, lower attachment to ground.

Refuelling safety

Engine off, no smoking, no ignition sources. Use appropriate funnel, avoid spills, use grounding if required.

Fuel spill response

Stop source, contain with spill kit, prevent entry to drains, report spill, dispose of contaminated material properly.

Waste disposal

Hydraulic oil, filters, batteries must be disposed of according to environmental regulations. Use approved recycling facilities.

Noise control

Use hearing protection if noise exceeds 85 dB(A). Maintain mufflers and report excessive noise.

Wind speed limit

Cease operations when wind exceeds manufacturer's limit (often 20 m/s). Monitor wind conditions and secure machine if necessary.

Overhead power line clearance

Maintain safe distance from power lines: typically 4.5 m for low voltage, more for high voltage. Use spotters and barriers.

Load security

Secure loads with twist locks, lashing or other methods. Ensure load is stable before lifting and traveling.

Incident scene preservation

Do not disturb incident scene except to assist injured persons or make safe. Preserve evidence for investigation.
