Understanding MEWPs
MEWPs, including scissor lifts, boom lifts, and cherry pickers, are designed to provide temporary access to work at height. They offer a safer alternative to ladders and scaffolding but require proper training and adherence to safety protocols.
Key Hazards Associated with MEWPs
- Falls from height
- Tip-over incidents
- Electrocution from overhead power lines
- Crushing or entrapment
- Collision with objects or structures
- Mechanical failure due to poor maintenance
Safety Guidelines for MEWP Operation
1. Training and Certification
Only trained and certified operators should use MEWPs. Ensure all operators have completed a recognized training program and possess valid certification.
2. Personal Protective Equipment (PPE)
Always wear appropriate PPE, including a full-body harness with a lanyard attached to a designated anchor point on the platform.
3. Load Capacity
Never exceed the MEWP’s rated load capacity, including the weight of personnel, tools, and materials. Adhere to the manufacturer’s guidelines strictly.
4. Stability and Positioning
Set up the MEWP on firm, level ground. Use outriggers or stabilizers when provided. Avoid working on slopes unless the MEWP is specifically designed for such use.
5. Environmental Considerations
Be aware of weather conditions, particularly wind speed. Most MEWPs should not be operated in winds exceeding 28 mph (12.5 m/s). Consult the manufacturer’s guidelines for specific limits.
6. Electrical Safety
Maintain a minimum safe distance from power lines as per OSHA regulations. For lines up to 50kV, maintain at least 10 feet (3 meters) of clearance.
Pre-Use Inspection Checklist
Before operating a MEWP, conduct a thorough inspection:
- Check for hydraulic leaks
- Inspect tires for proper inflation and damage
- Test all controls for proper function
- Ensure guardrails are secure and in good condition
- Verify that all safety devices, including alarms and emergency stops, are operational
- Check fuel levels and battery charge
Emergency Procedures
All operators should be familiar with emergency procedures, including:
- How to use the emergency lowering system
- Procedures for reporting mechanical issues or accidents
- Evacuation plans in case of equipment failure or environmental hazards
Conclusion
MEWPs are valuable tools that enhance productivity and safety when working at heights. However, their safe operation relies on proper training, adherence to guidelines, and constant vigilance. By following these safety practices, we can significantly reduce the risk of accidents and ensure a safer working environment for everyone involved in MEWP operations.
Key Takeaways and Best Practices
- Always use fall protection equipment when operating a MEWP
- Conduct a thorough pre-use inspection before each shift
- Never exceed the MEWP’s load capacity or reach limits
- Be aware of overhead obstructions, especially power lines
- Ensure proper setup on stable, level ground
- Maintain clear communication between the operator and ground personnel
- Never move the MEWP while the platform is elevated, unless designed for that purpose
- Keep the platform floor clear of debris and potential trip hazards
