What does OSHA require regarding the angle of slings when used with hooks?

The correct choice emphasizes that OSHA regulations require the angle of slings when used with hooks to not exceed 90 degrees. This guideline is crucial for ensuring the safe lifting of loads, as exceeding this angle can significantly affect the sling's capacity and increase the risk of failure during operation. When the angle between the sling legs becomes too steep, the load is subject to greater forces that can lead to slippage or even the breaking of the sling itself, making it vital for operators to maintain a safe angle.

Angles greater than 90 degrees can also lead to uneven weight distribution across the slings, causing potential instability during the lift. Proper training and adherence to OSHA guidelines are essential to ensure safety and minimize the likelihood of accidents. Keeping the sling angle within the specified limits contributes to the overall effectiveness of the lifting operation and protects both the load and personnel involved.
