After all the messages about WD-40 vs. propane for locating manifold leaks,
I feel compelled to add the following information. While WD-40 may be less
of a safety hazard under the hood of a truck, it is certainly very volatile.
The FBI Bomb Data Center issued a notice to all Bomb Techicians about 2
years ago concerning several accidents that occured while using WD-40 around
explosives.
Reason: THE PROPELLANT THAT EXPELS WD-40 FROM THE CAN IS PROPANE.
Spraying with the can upside down will give you a squirt of pure propellant.
Propane is also heavier than air, which causes it to pool in low areas with
poor ventilation.
That being said, I (like everyone I know) use it all the time for a million
things. The lubricant certainly reduces the ignitability to some extent.
But don't think for a minute that you are avoiding propane by using WD-40.
