About once a year I am asked to give advice on fighting a fire on a merchant shipping vessel. One of the first things I instruct the crew to do is to top up every tank adjacent to the fire space. This includes ballast, fresh water, fuel and lubricating oil, every tank. If they can't transfer fuel from another tank to top it up, they are told to pump in sea water. With very rare exception, liquids do not explode and cannot burn. If the vapor space in the tank is eliminated, the chance of explosion is minimized. I can't speak for the painter, but I would generally consider a full wing tank to be safer than empty. The biggest issue is to keep the flammable vapor mixture away from the ignition source. i.e.; keep the fuel cap on. As for blowing the dust off with air, isn't this the same as flying? In flight configuration, this had better be safe.
