PJ,

but which ‘
manual handling’ skills …
… and what range of skills is required to ‘avoid’ vs skills to ‘recover’, and to avoid or recover from what?
There seems to be greater opportunity for improving safety by reconsidering the role of the human, not as an item to be controlled (a hazard to be improved by training), but as a resource to be used before the event, not after when the skills demands are greater.
It’s better to stay within a relatively well defined operating area than attempt to train for a much wider range of scenarios outside of the norm, often unknown or predictable.
Thus which skills are required to keep within the normal envelope?
@F4, yes
knowledge, but which
theory, what depth and form of training, how much; there is no simple answer only a balance of judgements which are more often wrong after an event.
The industry requires foresight, often only available with hindsight.
Many contributors, perhaps all of us, suffer from
‘OOS-HEV’. The link identifies the symptoms, contributory factors, and identifies treatment and prevention.
