Pinky, sadly no, I never do...
The content involved a two hour classroom session (complete with powerpoint) followed by several hours of climbing up and down aerobridge stairs in various aircraft configurations while being assessed from below by the accredited stair trainer. One of the participants was rather unfit and nearly passed out after the fourth configuration, which possibly would have made him Australia's first safety course related fatality.
The benefits were to absolve the stair owner of liability in the event of someone doing something unapproved. There had been an incident where a person had been seriously injured on said stairs (due, unfortunately, to their own ineptitude) and the owner was worried about future lawsuits. The siren, flashing light and big sign saying 'do not use when stairs are in motion' were not considered sufficient warning.
Cheers to your red! Mine's Italiano tonight, but the sentiment's the same.
(P.S. I do not want to make light of this F/A's accident and I'm very glad she's not more seriously injured. If safety procedures need to be tightened up then so be it. I just get tired of OH&S for its own sake, as IMO it's become a self perpetuating industry).
