In any case one of the SAR crew could exit the aircraft and brief with the deck crew before anyone approaches the "whirling machine of death".
If you read my post you will see that is exactly what the SAR crewman tried to do but the refuellers ignored him completely and did their own thing - that was what was dangerous and the rig operators took the hit and rebriefed their crews.
SAR helos didn't have access to the rig SOPS - it was an emergency SAROP after all.
Ralph, you are right about the light procedures for DLs but that is very specific and detailed in Br766d - we are talking about a rig operation here.
