Hi Everyone,
I read John's post. While it is correct, there is something else to consider. First
I am a 27 year Firefighter and a Hazardous Material Technician.
Evans will burn, but so will others if it gets hot enough. Just about anything
will burn if it gets hot enough. Other coolants will burn and so will the oil
in your engine and the fuel and the hoses and the wire insulation and your planes
body.
Then how do we put in perspective the Evans burning issue? Well if it gets to that
point then all the other things in the area will be on fire and you have much
bigger problems than worrying about your coolant catching fire. All the other
things under your cowling burn at lower temps. and could be the cause of the
fire on top of burning. So by the time Evans is ever a factor you will have
far greater problems.

What if a tiny leaks develops and sprays pure propylene glycol (an
alcohol) onto your red hot turbo housing ? The coolant pressure is about
1.2 bar.
In my opinion, the Evans will instantaneously be a factor, and things
may quickly start deteriorating.
On of us honorable listers is setting up a hair-raising experiment to
determine if there is a difference between the Evans and the 50/50 mix.
His findings may prove interesting.
Best regards,

Hello Roger
As far as Evans burning, comprimise the cooling plumbing and spray it on
the turbo of a 914 and the order can be reversed.

I plan to test burn some Evans and try spraying it on the Turbo of my
Volvo Wagon to see just how easily it ignites.

I didn't mean the Volvo, but you have now given me new ideas! I will
conduct testing on my Volvo in my garage, and collect on both Auto and
Home Owners Insurance.
What's your address, I am pretty certain the insurance company will want
it!

Lees Correct,
Even water burns ..... Hold out your hand 8-)

Hi Guys,
Light a fire and throw Evans on it. It will put the fire out. It has to get hot
enough first. A Rotax is not a Turbo Volvo. Two different animals. The ethylene
glycol in 50/50 will burn in a car fire. I know I have put enough of them out,
but the fire was very hot with other materials involved. The water evaps and
leaves behind the ethylene glycol. I will worry about other things burning
long before I worry about the Evans. Fires in engines usually start from fuel
leaks or electrical shorts. That makes up probably 98% of all engine fires. Even
oil rarley causes a fire by itself, it usually smokes you out.
Without testing, I'm not sure your turbo will start it burning? Maybe? You will
have to heat it past its auto ignition temp.

Roger,
> Light a fire and throw Evans on it. It will put the fire out.
Are you really sure on that one ? Of course there have been cases when
throwing fuel on a fire put it out, but it rarely really happens.
Fuel, oil, alcohols all are flammable.
Here are some propylene glycol properties (Evans NPG) :
"Flash point: 99C c.c.; 107C o.c.
Auto-ignition temperature: 371C
Explosive limits, vol% in air: 2.6-12.6"
> It has to get hot enough first. A Rotax is not a Turbo Volvo.
The Rotax turbo is an Garret auto turbo, a very common one.
> Two different animals. The ethylene glycol in 50/50 will burn in a car fire.
I know I have put enough of them out, but the fire was very hot with other materials
involved. The water evaps and leaves behind the ethylene glycol. I will
worry about other things burning long before I worry about the Evans. Fires
in engines usually start from fuel leaks or electrical shorts. That makes up probably

smokes you out.

Fuel, oil, hydraulic fluid, alcohol leaks and an ignition source.
The Rotax turbo gets dull red when it use. That is about 700-800C,
twice the autoignition temperature of the Evans.
I'm looking forward to hearing from Ron's experiment.

Gilles
