I also remind any passengers that dis-embark whilst the rotors are in motion to ensure they exit forwards and outwards.
This varies between types. There are several helicopters which can only be safely approached, with rotors turning, from the side or in some cases even the back. The key is to ensure that all pax are briefed with the relevant specific instructions before embarkation/disembarkation.
The report also intimates that the helicopter was being refuelled with rotors turning. A recipe for disaster.
Hot fuelling is not a recipe for disaster. Performed correctly it is quite safe.
