Health & Safety, "an employer is required to take all reasonable precautions to ensure the Heath and safety of an employee."
... so lets get this right, you bought a modern machine with crash survivability, but no one has pointed out that there is a risk of burns from, fuel, oil, grease, battery acid etc when the machine survives its crash or catches fire? Do you guys not need a SMS, or have you just not done a H&S risk assessment?
I bet you ware helmets because of the risk of being blinded when the duty Duck comes through the windscreen...same thing!
This doesn't need to go to ICAO , EASA or whateber references it's a basic duty of care issue.
