I was reading through some mails and it appears to me, that the users seem to be to blame in many instances. I would say that it is inevitable when they usually know nothing much about gas safety. To me concentrating information just on GSR workers is plain silly. Its a bit like a car company making a car and not telling people how to use it and why they must use it in a certain way. Lets be honest, do people really realise how dangerous CO can be? The installer is not usually the person using appliances the majority of the time. I have been in houses where the fire front radiant's have been glowing a nice bright yellow, to find that the home owner or tenant thought there was nothing wrong. After all, its the user the gas regs are designed to protect not the installer, why keep them ignorant of how things work and what and why to look out for, it is after all usually their lives at risk not the installers?
