I understand that the focus of this is specific to the Seaking due to the engine exhaust / airflow combination which apparently created a particularly hazardous environment for those working in the door.

They were effectively sitting in the exhaust flow for long periods of time.

The exhaust gas path / airflow on other helicopters will be different (which is not to say that there may not still be a risk) but this particular case is based on Seaking (and evidence that UK MOD were aware of health risks to crew operating in the door).
