Well, yeah er we  we had a fair amount of chemical er troubles erm mainly spillages, bad packaging, erm a few accidents erm, and very little information in those early days erm  there was a lot of nasty chemicals going around which erm very little information followed it and people were being quite seriously injured, firemen included, policemen and others were getting involved with these things, and I got myself involved quite a lot with the various bodies that deal with chemicals, like the Chemical Industry Association, and people of that kind, trying to make things a bit safer, and taking up cases where spillages had occurred and, and accidents had happened er to try to get to the bottom of it and try to improve the situation and er I wasn't alone, most Chief Officers were working that way and certainly the London Fire Brigade did it, did no end of work with producing, what is now commonly known as the  coding and, and a system of, of erm er marking containers of chemicals so that people can understand how to deal with them, so that that was quite an interesting area which, even now I'm now retired I still have a little hand in that with er chemicals er in my few moments I have spare I, I get involved with that side, which I enjoy.
