Securing Elevated Work Platforms Toolbox Talk

Elevated work platforms, including mobile elevating work platforms (MEWPs), provide safe access to work at height when they are properly selected, inspected, and operated. However, improper setup, unstable ground, overloading, or failure to follow safe operating procedures can result in tip-overs, falls, or collisions.

This toolbox talk reviews how to secure elevated work platforms before and during use, helping protect operators, occupants, and workers on the ground.

Why This Matters

• Unstable or improperly positioned work platforms can overturn or collapse.
• Correct setup improves stability and reduces the risk of falls.
• Following manufacturer instructions helps prevent equipment failure.
• Ground conditions and weather can change throughout the workday.
• Proper inspections and safe operation protect everyone in the work area.

Common Hazards

• Operating on soft, uneven, or unstable ground.
• Exceeding the platform's rated load capacity.
• Failing to deploy outriggers or stabilizers when required.
• Working too close to overhead power lines.
• High winds affecting platform stability.
• Driving or repositioning the platform with the boom or platform elevated where prohibited or unsafe.
• Workers climbing on guardrails or using ladders inside the platform to gain extra height.
• Equipment struck by vehicles or other mobile plant.

Safety Checklist

Before Work Begins

• Inspect the elevated work platform according to company procedures and the manufacturer's recommendations.
• Verify the equipment is appropriate for the task and working height.
• Inspect tires, controls, guardrails, gates, emergency lowering systems, and safety devices.
• Ensure the work surface is firm, level, and capable of supporting the equipment.
• Deploy outriggers or stabilizers as required and confirm they are properly positioned.
• Identify overhead hazards, including power lines, structures, and tree branches.
• Confirm operators are trained, authorized, and familiar with the equipment.

During Work

• Keep both feet on the platform floor and remain inside the guardrails.
• Wear required fall protection when specified by the manufacturer or site procedures.
• Do not exceed the platform's rated load capacity.
• Maintain safe clearance from overhead power lines and other obstructions.
• Monitor weather conditions and stop work if high winds or other hazards affect safe operation.
• Use a spotter when visibility is limited or when operating near hazards.
• Report equipment defects immediately and remove unsafe equipment from service.

Crew Talking Points

• Has the work platform been inspected before today's use?
• Are ground conditions suitable for safe operation?
• What is the rated load capacity of the platform?
• Where are the nearest overhead hazards or power lines?
• What emergency procedures apply if the platform becomes disabled?
• Speak up immediately if you notice instability, equipment damage, or unsafe operating practices.

Stop Work If

• The work platform is damaged or has not been inspected.
• Ground conditions are unstable or cannot safely support the equipment.
• Required outriggers or stabilizers cannot be properly deployed.
• Weather conditions make operation unsafe.
• You cannot maintain safe clearance from overhead hazards or power lines.
• The platform becomes unstable, overloaded, or develops a mechanical problem.

Final Reminder

Secure setup leads to safe work at height. Inspect the equipment, verify stable ground conditions, follow the manufacturer's operating instructions, stay within the platform's limits, and stop work immediately if conditions become unsafe.
