Sorry if you have taken my replies to mean I wish to ridicule any juniors, quite the opposite. My point is that your LFf is doing just that by asking you to find out useless information. You should be receiving meaningful development, knowing the BSEN maximum weight of a BA set is not. I truly believed that we were well past the ridiculous fire service 'know all the technical details' and into true, relevant., development. You DO NOT NEED TO KNOW the maximum weight of a BA set. You DO NEED TO KNOW its duration and how to wear/service it and the procedures for your safety. This is the sort of true development you should be getting. Asking you to go away and find out something that you will never need to know is simply abdicating the LFf's true responsibility, he/she may not actually have enough knowledge/skill to deliver the correct level of development to you, they do appear to be in need of some development themselves.
To emphasise: I truly believe that new joiners are our future, we need to develop them correctly, we do not need to live in the past.
Trainer: if they made BA sets heavier we would have less duration as Ffs became tired more quickly, indeed the change from steel to composite cylinders was done to make sets lighter and reduce the stress on the wearer. This has the potential to reduce air consumption. Think logically!
Billy - thanks for your comments
Hopefully Frankie can see through to the sense here and that we want him/her to develop with the required skills and knowledge. Having such trivialities in their head means they may miss out on the really important information. I too learnt such fascinating facts as the length of a ceiling hook, the weight of a length of hose, the weight of a FWMP, the diameter of a guideline and many, many more. I have never needed any of these and never will. I have used a ceiling hook that was not quite long enough to reach, I couldn't have measured the gap anyway. I have carried two lengths of hose one under each arm, they were heavy and I only had two arms so no matter how light/heavy that was my limitation, I have struggled (with another 3) to manouvere a FWMP I knew it was b***dy heavy, but the weight per person is supposedly less than those two lengths of hose - it is the one-handed/slight squat carrying position that matters. I have never had to use a guideline operationally, though if I ever did I would not care two hoots what its diameter is as long as my line hook went over it.
PS I did know about BS not being legally binding and that it is their mention in any law/regulation that gives them a legal footing! But thanks for the discussion for those that didn't. This may be of benefit to a Ff asked to give advice to the public - Frankie here is some useful info!
