Operating an Elevated Work Platform (EWP) over 11 metres carries significantly higher risk than smaller lifts. Because of this, operators must meet strict licensing, safety, and compliance requirements. Whether you’re a worker, supervisor, or PCBU, following these rules helps prevent incidents, ensures legal compliance, and protects everyone on site.
1. Hold the Correct High-Risk Work Licence (Class WP)
Any boom-type EWP with a boom length over 11 metres requires a High-Risk Work Licence (HRWL).
This ensures the operator has completed accredited training and demonstrated competency in:
-
Safe operation of high-reach boom lifts
-
Emergency descent procedures
-
Identifying and controlling height-related hazards
-
Conducting pre-start and post-operation checks
Operating without this licence puts both the worker and employer in breach of WHS laws.
2. Conduct a Detailed Pre-Start Inspection
Before using the equipment, operators must complete a full inspection, checking:
-
Tyres, wheels, and outriggers
-
Platform controls and ground controls
-
Emergency stop functions
-
Guardrails and anchorage points
-
Hydraulics, hoses, and wiring
-
Fluid levels and battery condition
Any faults must be reported before the EWP is used. Repairs should only be performed by an authorised person.
3. Assess the Work Area for Hazardous Conditions
Working above 11 metres increases exposure to environmental and structural risks. Assess the area for:
-
Overhead powerlines
-
Ground stability and slope
-
Wind and severe weather
-
Traffic management requirements
-
Nearby structures, machinery, or people
If the risk cannot be eliminated, it must be minimised using controls such as barriers, spotters, signage, or repositioning the EWP.
4. Use Fall-Protection Equipment Correctly
Most boom-type EWPs — especially at height — require operators to wear a full-body safety harness attached to an approved anchor point inside the platform.
Key rules:
-
Lanyards must be the correct length to prevent ejection from the basket
-
Harnesses should be checked for wear, tears, or defects
-
Never attach the lanyard to railings, tools, or improvised anchor points
-
Everyone in the platform must be clipped on
Fall protection is a legal requirement, not a recommendation.
5. Monitor Wind Speed and Weather Conditions
EWPs over 11 metres are highly sensitive to wind. Always check:
-
The manufacturer’s maximum wind rating (often 12.5 m/s or 45 km/h)
-
Sudden wind gusts or storm activity
-
Rain, lightning, or low visibility
If wind speed exceeds the limit, the EWP must not be operated. Sudden gusts at height can destabilise the platform and cause tip-overs.
6. Keep the Platform Load Within the Rated Capacity
Overloading an EWP at high reach is a major cause of incidents. Be aware of:
-
Maximum platform capacity (including tools and equipment)
-
Number of people allowed in the basket
-
Uneven weight distribution
-
The increased impact of load at full boom extension
Always plan the task so only necessary tools and workers are elevated.
7. Maintain Clear Communication and Emergency Readiness
At heights over 11 metres, communication is critical. Ensure:
-
Ground staff and spotters understand their roles
-
Clear hand signals, radios, or communication systems are established
-
Emergency descent and rescue plans are in place
-
Ground controls remain accessible
-
Only authorised personnel operate controls
A prepared team can significantly reduce risks during unexpected situations.
Using an EWP above 11 metres requires more than basic operating knowledge. it demands strict compliance with WHS regulations, manufacturer instructions, and site-specific safety procedures. By following these seven essential rules, operators and PCBUs can create a safer work environment and reduce the likelihood of serious incidents.
