this thread discussion is my point exactly...it's too open for interpretation and not mandatory enough for exceptions.
If you think about a deployment....most are more than 1 day, you are away from you own bed (and I personally don't sleep well on deployments) travel time, for some may be hours worth and then you may have to return to work the next day...48hrs is definitely needed to recover...
As for those who have said, they don't have to respond if they are tired...right, and if the bells go, so does your adrenalin, feel tired, nope, going....many are NOT that responsible to rest, which is why I believe it should be more black and white...
and yes, the main issue is OHS, something we base ALL of our SOP's etc around...why should this issue be excluded...
how many firies would actually stand themselves down if they started to fatigue on the fireground???
I have seen some go past the point of being able to function effectively and start making stupid decisions because they are too tired...
