There is no definitive maximum wind speed at which rope access work should be stopped, O.2.2.2 as this depends on many factors, e.g. place of work; company policy; nature of the task. In other trades, recommendations vary for maximum wind speeds at which work should be stopped. The recommendation for falsework is that a maximum working wind force during operations is Force 6 on the Beaufort scale. This equates to 10.8 to 13.9 m/s. For roofing work, e.g. laying or handling profiled single-skin sheets at roof level, it is recommended that work should stop when the mean wind speed reaches 23 mph, gusting to 35 mph or over (10.3 m/s or Force 5 on the Beaufort scale). For lightweight materials, e.g. insulation boards, this is lowered to 17 mph, gusting to 26 mph or over (7.6 m/s or Force 4 on the Beaufort scale).
