Just a question.

These are small fuel burners, what are the hazards associated with them.

I mean I was initially inclined toward the small screw idea, but then I got to thinking. We are afterall pressurising the fuel and heating it.

I've seen a BLEVE explosion even a small one is impressive to say the least. (read, scared the gravy out of me)

So ok these are not road tankers or pressurised cylinders, but over pressurising even a small can like these could I believe be a little dangerous.

So to the more experienced members and firemen here what are the risks in real terms, if any?
