I have been following this subject with some interest. I do not want anyone for one moment to suspect that I have no respect for pressure and what it can do. (engineers out there may have read the Cockenzie report years ago).
I am holding in my hands a gas canister it is about 8 inches high and about 2.5 inches diameter. it is a butane propane mixture (30%) these cans get left in direct sun on construction sites all over the world The temperatures can be at times to hot to hold almost. These cans are on sale at all hardware suppliers the material is under 1mm thick. I am for safety very much, but I sometimes get the feeling that in our belt and braces society of today there may be a tendance to exaggerate. Has anyone done the calculations on these cans?. Just an example a Champagne bottle holds up to 150 psi with a cork and a bit of wire. A bomb? These are just thoughts and they may cause someone to come with a not so dramatic solution. I am not suggesting making a gas tank of 1mm tin plate. Bert. ------------------------- Bert & Edmunda [EMAIL PROTECTED]
