I got in touch with Texatherm to ask the obvious questions. Apparently it is not a health and safety issue to have to have the p.h. info on their containers or their msds sheets......and arent beaking any laws by not doing so......... Apart from the EEC, world wide it is required to have that info....... Those who bye the Tex system are trained in what is for what and would know the relevant ph's. If it is then sold on to another person that info would not go with it so to speak. I see a serious problem with this as from time to time most systems are sold to another person at some time or another. Tex agreed with those thoughts but of course have no control over them.. My better half is an orthopeadic trauma nurse but also works on A and E on many occasions. When a chemical instant occurs one of the first assesments is to the p.h. of the chemical. Even though apparently it is not a legal requirement (Deb doesnt know either way), surely for this reason alone it should be labelled........ but just my opinion. .... The Tex man although all for his system did suggest it has limitations. The entrance matting for one (which I found out last week) but also on berber carpeting. Other than that he advised that it should clean quite well. He also suggested it should out perform the portable hwe that I use....... But I dont use a portable, anyway........Think I will stick to my machine, best , Dave
