I must be missing something here, will the guys using these canisters on shows please enlighten me? Has anyone got a translation of a MSDS for this substance? Anyone care to share their COSHH risk assessment? Does it produce phosgene gas when burned as do some brake cleaning fluids? Like Wynns down under, David. Does it contain the carcinogen benzene? Which form of the dozens of substances called naphtha are you igniting? What is the propellant in this stuff? You must have found out the answers to all these questions before burning it in any enclosed public space, so please share your knowledge with me. I'm not surprised that Clive cannot find it in the UK, must be a reason? Just like topic 40931 #34 I am not saying it is dangerous but I don't know and, I submit, neither do you.
