Diesel fumes will explode.
What's the risk
While diesel fuel isn't as combustible as gasoline, it's nearly so. When static electricity discharge occurs with combustible vapors present, a fire or explosion may result while you're fueling your vehicle or equipment.
Intresting.. Now some observations and qustions:
I have observed, with my own eyes, a flash pan filled with diesel, a lit match tossed in said pan acted like it was being tossed on water. Fill the same pan with gasoline and WHOMP it ignights when a match is tossed, but the diesel put the match out.. More on this later.
Static electric sparks are dangerous where gasoline is involved due to the above, But answer this: How does shutting the engine off or leaving it running affect static build up? Your butt sliding on the vehicle seat, Your shoes on assorted surfaces yes, but the engine?
The promised more:
That test was run at ambient temp, say 70-80 degrees,, Heat Diesel to the boiling point and it WHOMPS too.
Besides it being the law to shut the engine down, suppose the running diesel engine developed an injector leak or came in with an injector leak. I know, diesels NEVER leak around the injectors or have any other high pressure fuel issues. Engine fires NEVER happen on diesel coaches, etc, etc.
Now you have high pressure diesel fuel being ejected in a mist which would probably be more flammable than a pan of diesel fuel.
Basically it just boils down to idling is unnecessary and all of the engine manufacturers recommend against it. Maybe it is true about teaching old dogs new tricks. :B
