Operating MEWPs in Windy Conditions
Whilst working at height, one of the most critical factors to consider is wind speed. Mobile Elevating Work Platforms (MEWPs) are essential piece of equipment for many industries, but they can become unstable and unsafe when used in strong wind conditions. Understanding how wind affects MEWP operation is key to preventing accidents and maintaining a safe working environment.
The Impact of Wind on MEWP Stability
High winds can significantly reduce the stability of a MEWP. Even moderate wind can cause the platform to become unbalanced, especially when it’s extended to higher elevations.
When the MEWP is positioned at a low level, buildings and structures can shield or funnel wind which may suddenly affect the platform stability. A calm breeze at ground level can quickly turn into a strong gust several metres above, putting both the operator and equipment at risk.
Checking Wind Speeds Before and During Operation
Before any work at height begins, anemometer should be used to check the current wind speed. This should be regularly throughout the day, as weather conditions can change suddenly.
Operators should take readings at different heights to ensure the conditions remain within safe limits. Continuous monitoring helps detect sudden changes in wind speed, meaning that necessary actions can be taken before the weather conditions become unsafe.
MEWP Wind Ratings
Not all MEWPs are designed for outdoor use, and each model has a maximum safe wind speed rating which is typically 28 mph (12.5 m/s). This information can be found on the machine’s data plate or in the operator’s manual as it can vary depending on the machine.
Additional Safety Considerations
Before installing any additional equipment or attachments, you should consult the manufacturer to confirm the ongoing stability of the machine.
