Take a look at verisafe.co.nz . I like it because it's simple, transparent and it works.

From a OHS risk management perspective, the term 'critical risk' has always been a concern, because the existence of an 'intolerable risk' should result in a work shutdown. The other day I met an old colleague from the chemicals industry who is now a senior ops manager in Queensland. They talk about 'critical hazards', which if are not robustly controlled become intolerable risks. In that context, it makes far more sense to me.

Just received the email reminding me to check the website. Great, thanks. Would it be possibel to include a hyperlink in the email to the forum webpage to make life even easier?

Thanks Peter, will look out for the email tomorrow. Weekly update would be great.
