Here's a hint for people that go through industrial tunnels and see wooden sticks on holders near the entrances. They're there for a reason. The reason being if there's a steam leak you probably won't see it, you might hear it and you'll definately see the water on the ground. By that point you might have lost your ear, eye or arm because some steam leaks can cut like a steam knife. So just remember to grab the stick and wave it front of you as you walk along and when the end goes flying off that means don't go there.
