Wow, thank you so much for all your comprehensive replies! I checked to see if there was a response a couple of days later, but didn't realise that there had been subsequent responses until now (so please accept my belated thanks). In particular, your summary by state is great arowe
Our OH&S Auditor (for our current certification) has advised that a national committee will be fine. However, you raise some interesting legislative points here that I also need to be aware of (ie - need a state committee if members request it, etc).
So thanks again!
