I am with Craig all the way on this one, Meggamouse lives on it's trolley from leaving the car to loading into the arena. It makes for a secure cradle and I can work on it much easier. I too have seen more than 1 bench collapse with a heavyweight on it.
Where possible I try to get an end bench to keep the trolley out of the aisle, but have in the past moved benches along to store in the gap. Some venues are limited in their pit space, I know, but it wouldn't hurt to leave a gap, also, gangways will be kept clear as no-one will have any more excuses.

Tools to turn on and off gas. I made the first one as it was impossible to get my hand into Meggamouse for access. It had been raised at an FRA meeting 3-4years ago by Dave Moulds, but nothing was decided then - it was suggested, though, that it had to use a 17mm socket welded to a handle - so that was what I used. I find it so much safer, if anything is amiss I haven't got my hand buried in the machine. Jonno liked the idea and copied it - well he borrowed mine until I hid it - then he had to make his own.........Toonraider now has one and I am sure Pete feels the benefits when de-gassing using the tool.
I don't think making it compulsory is the way, but for new builds it should be highly recommended.
