hi Craig

In the wind industry we have a standard minimum default distance of 1/5th the height of a wind turbine as our drop zone. any working at height we also mandate that all hand tools, phones, radios, bags etc have to be tethered.

If you are getting push back on setting up drop zones due to the working environment i would enforce the tethering of all tools and equipment and that no persons should be below anybody working at height. Though this may not always be possible which is why tethering of tools has to be mandated where practicable.

hope this helps
