Avoid Overhead Crushing - Health and Safety
Best Practice Guidance for Manlifts
Introduction
Working with Mobile Elevating Work Platforms (MEWPs) requires strict adherence to safety protocols to prevent accidents, particularly crushing injuries. This guidance is aimed at MEWP operators, supervisors, and rescuers to enhance awareness and provide actionable steps to mitigate risks.
Understanding the Risk
Crushing injuries occur when the MEWP platform or basket comes into contact with overhead obstructions such as beams, ceilings, or other structures. In the Gulf region, where construction sites are abundant, the risk of such incidents is heightened. Poor visibility, distractions, wrong MEWP choice, and lack of training can cause crushing injuries with MEWPs.
Legal Framework
Occupational health and safety laws mandate the use of properly maintained equipment and certified operators. Adherence to the Gulf Cooperation Council (GCC) standards and local safety regulations is crucial. For instance, all MEWP operators must be trained and certified, and equipment must undergo regular inspections.
10 Ways to Reduce the Risk of Crushing Injuries
Careful MEWP Route Planning
Distance from Obstructions: Plan the route of the MEWP to maintain a safe distance from overhead obstructions. This distance should account for the potential "bounce" and "see-saw" effects, particularly in boom-type MEWPs.
Avoid Certain Controls Near Obstructions
When working close to overhead structures, avoid using the drive, elevate, or slew controls. Instead, use fine-positioning controls to minimize the risk of unexpected movements.
Use Slow Speeds When Driving at Height
If driving the MEWP at height is unavoidable, operate at the slowest possible speed to ensure precise control. Sudden movements should be avoided to reduce the likelihood of an accident.
Select the Right MEWP for the Job
Ensure that the MEWP selected is suitable for the specific task, especially when working near overhead obstructions. The machine’s reach and size should be appropriate for the workspace.
Specific MEWP Familiarisation Training
Operators should receive specific familiarisation training for the MEWP being used. This should include hands-on training in a low-risk area, away from overhead obstructions, and emergency procedures should be regularly practiced.
Ensure Stable Ground Conditions
The ground should be level, compacted, and free of obstructions. In the Gulf region, where sand and uneven terrain are common, special attention should be given to ground stability for MEWPs.
Maintain Good Visibility
Adequate lighting must be provided, especially when working indoors or during low light conditions. Work should be suspended during poor visibility conditions to avoid accidents.
Minimise Distractions
Remove distractions such as mobile phones and loose materials from the platform. Ground-level distractions should also be minimized to ensure the operator’s full attention is on the task.
Do Not Obstruct MEWP Controls
Keep all controls free from obstructions. Tools and materials should not be placed on the control panel, and power should be isolated when the MEWP is not in use to prevent accidental operation.
Rehearse Rescue Procedures
A clear and practiced emergency rescue plan is essential. Ground staff should be familiar with the MEWP’s emergency controls and capable of executing a rescue swiftly if needed.
Common Rescue Problems and Solutions:
- No Emergency Plan: Always have an emergency rescue plan in place before starting work. Ensure all team members know their roles in the event of an emergency.
- Ground Control Familiarity: Ground personnel should be familiar with the emergency descent controls and practice their use regularly.
- Rapid Response: In the event of a crushing incident, immediate action is crucial. Operators and ground staff must be trained to respond swiftly to minimize injury.
Conclusion
Safety is paramount when operating MEWPs. By following the best practices outlined in this guide and adhering to local laws, you can significantly reduce the risk of crushing injuries and ensure a safer working environment.
