Obviously training is important, and it's an ongoing commitment to training any time you're dealing with human beings. You'll never get things perfect, but there is a commitment to training. If a leakage is strong enough, there are the other laws, the environmental laws and whatnot that come into play. If there is some systemic problem, it would show up and it would be dealt with through the enforcement system. In terms of dealing with human beings, you have to make sure that they're properly trained and that you're monitoring them as best you can to make sure the proper procedures are always being followed. That's part of a safety management system.
