Think about it. If the crane has no load except the below the hook device are you allowed to lift it and transport it with an overhead crane over someone’s head? I am hoping your answer is “no” because that is the correct answer. People will try to argue this on many levels but you are never allowed to lift any load over someone’s head. I will visit customers and I am amazed at what I often see. Loads are continually lifted over personnel’s heads, and because no one has ever gotten hurt they continue to do so. Is that what it takes to get people to not do something they really shouldn’t be doing? I truly think OSHA needs to spend more time visiting facilities in the general industry and monitor their operation.
In 2007 OSHA wrote an interpretation letter specifically regarding this issue. Never is there a time when it is ok to lift something over someone’s head. This letter refers back to OSHA’s regulation 1910.179 (n)(3)(vi) which states, The employer shall require that the operator avoid carrying loads over people. It is the employer’s responsibility to ensure that loads are not carried over someone’s head.
However, because of how this regulation is written, many people will argue that it is ok to carry an empty below the hook device over someone’s head because it is part of the crane. Again this is incorrect. OSHA defines a load as, the total superimposed weight on the load block or hook. Therefore anything below the hook is considered part of the load. This would include slings, spreader beams, scales, magnets, e.t.c.
