Working Safely with MEWPs in Winter
The winter season is quickly approaching, which means shorter days and adverse weather conditions. Rain, snow, ice, or high winds can impact the MEWP’s stability, visibility, and manoeuvrability. Operators should always assess the weather and, in some cases, suspend operations until it is safe to continue. This can be a challenge when deadlines are looming and the pressure is on to get the job completed – however, all those responsible for working at height must put safety first.
If deemed safe to continue, the operator and those overseeing the task must be aware of potential changes in weather conditions throughout the day or night and, where necessary, lower the MEWP and seek shelter until it is safe to do so.
High Winds
High winds can affect the stability of the platform. Before starting any work at height, an anemometer should be used to check the current wind speed. Wind conditions should be regularly monitored throughout the day at different heights. The wind may be stronger at elevated positions compared to ground level. When the MEWP is positioned at a low level, buildings and structures can shield or funnel wind. The operator needs to be aware of any sudden changes in wind speed, meaning that the necessary actions can be taken before the environment becomes too dangerous.
Operators should check the MEWP, as some machines are not rated for outdoor use. The maximum wind speed a MEWP can safely operate in is typically 28 mph (12.5 m/s). Operators should verify this rating on the machine's data plate or by checking the operator manual.
Snow, Ice, and Low Temperatures
As temperatures begin to decline in the UK, businesses should have proper access to materials and accessories such as block heaters, battery blankets, hydraulic tank heaters, and freeze plug heaters. This will help prevent equipment malfunctions in low temperatures.
Always allow for the MEWP to warm up properly before use. In cold conditions, MEWPs may experience battery drain or sluggish hydraulics if the machine has not warmed up. All moving parts should be checked to make sure they are functioning correctly before using the MEWP.
The ground conditions should be inspected for snow or ice. Slippery surfaces are one of the most common causes of MEWP accidents in winter. Clear snow and ice from the work area to prevent the machine from losing stability. Keep in mind that temperatures throughout the day can change, so operators will need to monitor this.
Personal protective equipment (PPE), such as insulated boots or jackets, can count towards the total capacity of the MEWP. Operators should remember to check the operator manual for the maximum load capacity, because if they exceed this limit, the equipment’s functions will be disabled.
Additional Safety Tips
Winter weather conditions will reduce the visibility for MEWP operators. MEWPs should be equipped with adequate lighting, and operators should wear high-visibility clothing at all times to ensure they are visible on-site.
Certora offers a range of working at height training courses to ensure that those working at height or required to operate work at height equipment are fully prepared and remain safe throughout the year.
