Dunno about emigrating but it might be easier to move house!
No, you're right Oilman. I guess I had one beer too many before writing last night. But I still think some of these rules would be more effective as 'good practice' guidelines. The risks of a tank catching fire are still incredibly small, much lower than the dangers incurred by getting out of bed. To condemn a whole system for the sake of a detail that may involve a 1:1,000,000 chance of accident does not make actuarial sense.
With so many regulations to follow, there will always be people who think 'sod it, I won't bother' - as I did in gloomy mode last night. So they'll either cut more corners than they would if sensible advice was freely available, or they won't get around to replacing the system at all.
The risk of my system blowing up is already 2:1 (it has - twice!) so it would make more sense to let me freely get on with reducing that risk to 1:1,000,000. I'm already doing my bit for accident prevention simply by replacing the boiler.
You mentioned the dreadful Flixborough incident. Another one that springs to mind is Ronan Point, a tower block in East London that blew up in 1968 with serious loss of life. Funny, isn't it, how both were "state of the art" installations, one by a local authority, the other by the tightly-regulated chemical industry.
Cynical? Moi?
