Purge of bang? In an enclosed diesel engine acoustic module, diesel fuel with a flashpoint above 61 deg C falls on hot surface say 70 deg C. Ambient air temperature is 40 deg C. There is no purge or air change. I think the diesel fuel will evolve flammable vapours and eventually reach the LEL and we have a bang waiting to happen. The vapours will not condense back into diesel fuel once they have flashed off - we have basically refined the product and are now looking at the volatile fractions of the fuel - benzoates etc - and so we have a totally different set of characteristics to that of the original diesel.
Is there a hazard here that needs mitigation or am I wrong?
My view is that a continuous purge of the module is required to prevent the formation of an explosive atmosphere in the first place. Your input please.
