if your getting the wire escape pods we used to get in the oil indusry don't try them before you have to use them.
I made this mistake. They consit of a braked escaped pod which you jump into and away you go down the bit of string.
They way they used to work is that you jumped into them when the Blow out valve went, when they blew the BOP and you stuck your gas mask on and jumped off the derk in one of these things. YOu then headed towords the ground at something towards terminal velocity which is then stopped at 4.5g at the bottom. You only do it once and then you changed your carreer.
IF they offer you training get them to show you the door and which handle to pull and thats it you will only do it once. Its way worse than a min approach in ****e wx trust me.
