Heavy rainfall can reduce visibility for crane operators, making it difficult to gauge distances and perform precise movements. Rain-soaked surfaces can also become slippery, increasing the risk of accidents for workers on the ground.
The Occupational Safety and Health Administration (OSHA) recommends that crane operations cease when wind speeds exceed 20 miles per hour or when lightning is observed within a 6-mile radius of the work site.
Following these guidelines is essential for ensuring the safety of crane operators and construction crews, as well as preventing costly damage to equipment and delays in project timelines.
It is crucial for crane operators and site supervisors to stay informed about weather conditions and forecasts, utilizing reliable sources such as weather apps and websites.
In the event of a thunderstorm, crane operations should be suspended, and the appropriate shutdown procedures should be followed as outlined in the crane's operating manual.
This includes lowering the load to the ground or securing it safely, retracting the boom if applicable, and grounding the crane.
Understanding Thunderstorms and Their Impact on Crane Operations
The formation and characteristics of thunderstorms
Thunderstorms form due to the rapid upward movement of warm, moist air. As this air rises, it cools and condenses, forming cumulonimbus clouds. These clouds are responsible for producing lightning, thunder, heavy rain, strong winds, and occasionally, hail.
Thunderstorms can be unpredictable and develop rapidly, making it crucial for crane operators and construction site supervisors to stay informed about weather conditions.
