After a lap of the pool, the hard work starts. You have to swim to the bottom of the pool and do half a lap touching the bottom. I feel exhausted thinking about it! I don't know why but I found it harder than the rest and seemed to be swimming like mad to keep to the bottom.
One of the other tests was to drop your weight belt to the bottom of the pool and retrieve it! Doing all this in darkness would be something else mind.
The funny thing however is, although we are trained to go under water we are not allowed to. If the water reached the bottom of the SEFA unit we have to pull back. I think if it was possible to go on with not much danger i.e if the water dropped away immediately we had gone through, I think all these decision would be taken by the men in charge.
I have heard of a rescue that has been done under water once with North Sea divers being involved. They only got so far and gave up with the darkness. Some rescue men, led by two from Houghton, who are professional divers, managed to make it further than the North Sea divers! I am not sure what happened after this. I think in most cases today pumps would be used to simply pump the water away.
All told it was good to see the American miners all come out safe and well. As I have said before the water is really cold and can take your breath away.
The next time I send you some news I will let you know of the entrapment procedure we did in our training. |
