When there's a work refusal and it hasn't been resolved by the workplace parties, then our health and safety officers are called in to investigate. They basically look at all the information that's available to them. They look at the facts of the particular case in question; they look at all the information that's available, including any hazard assessment that's been done by the employer and the procedures that have been put in place. If there are any other relevant studies that have been conducted by others, those are also looked at.
Ultimately, the health and safety officer has to make a determination based on the requirements of the law as the situation exists at the time. As I've indicated, in the vast majority of those situations, based on the facts as they existed at the time, based on the information available to the health and safety officer, there was a finding of no danger, except in two circumstances that I mentioned earlier on in my presentation.
