Do I have to wear a harness or life jacket when working over water in a MEWP?

Working next to or over water must be assessed to identify whether the greatest risk of injury to the operator is from falling from the MEWP basket or drowning if the MEWP falls into the water.  The decision can then be made as to whether it is most appropriate to wear a harness to address the fall risk or whether a harness should not be worn due to the risk of drowning. Life jackets, not harnesses, should be worn where there is a risk of drowning.
