About being informed, anybody who gets on an aircraft heading to one of those platforms has to go through a mandatory training program before getting on the helicopter or the boat, even visitors. If you and I go as visitors, we will go through a mandatory briefing before we even get on the vehicle.
If I'm a worker who travels regularly, there are regularized updated briefings as they go through and go on. Then there's sort of the regular literature and the materials you'll find in the workplace that are distributed to workers. Then there's a dialogue through the committee structure that allows workers in the workplace to continue to be in constant discussion and dialogue about what some of the issues are, and if there are concerns, allows those concerns to be expressed and dealt with before they become issues and before they become hazards.
Then in the instance that is fairly extreme when there is something that could be deemed or thought to be dangerous by a worker, the worker has the right to refuse to engage in that particular activity.
You would expect, and I think practice demonstrates, that it's a pretty powerful right and one that you wouldn't utilize if you hadn't gone through due diligence, informed, taken steps, and believed that you were trying to make sure that your workplace remains safe. Certainly the experience as it kind of unfolds is very dynamic; it's fairly ongoing and it's something that a lot of time and effort is put into. There are very practical, as you said, ways: mandatory training, mandatory experience, and specific tasks and techniques that have to be managed. There are committees that can review things and appeal mechanisms. There's a whole suite of things.
