Hi I have some parts to clean and (have to clean them with ethyl alcohol) and it would be easist if I could "blast" the parts with high pressured ethyl alcohol spray gun. So I have a pump that I hooked a hose up to and I put a sprayer on it and tested it with water. Filled a bucket and plugged the pump in, and it sprayed out the hose pretty nicley. My question is can I replace the water with the ethyl alcohol or will it catch on fire?

can I run ethyl rubbing alcohol through a utility pump?

Even the high percentage ethyl rubbing alcohol (70%) is 30% water.
It won't burn.
But HEET or other "de-icers" are a different story.
I wpuld worry about drying out or desolving seals first.
An air pressure style spray gun would be the best.

Section 5: Fire and Explosion Data
Flammability of the Product:
Flammable.
Auto-Ignition Temperature:
The lowest known value is 399°C (750.2°F) (Isopropyl alcohol).
Flash Points:
CLOSED CUP: 18.3°C (64.9°F) - 24 deg. C (75 deg. F)
Flammable Limits:
The greatest known range is LOWER: 2% UPPER: 12.7% (Isopropyl alcohol)
Products of Combustion:
These products are carbon oxides (CO, CO2).
Fire Hazards in Presence of Various Substances:
Highly flammable in presence of open flames and sparks, of heat. Flammable in presence of oxidizing materials. Non-
flammable in presence of shocks
Explosion Hazards in Presence of Various Substances:
Slightly explosive in presence of open flames and sparks, of heat. Non-explosive in presence of shocks.
Fire Fighting Media and Instructions:
Flammable liquid, soluble or dispersed in water. SMALL FIRE: Use DRY chemical powder. LARGE FIRE: Use alcohol foam,
water spray or fog.
Special Remarks on Fire Hazards:
Vapor may travel considerable distance to source of ignition and flash back. CAUTION: MAY BURN WITH NEAR INVISIBLE
FLAME. Hydrogen peroxide sharply reduces the autoignition temperature of Isopropyl alcohol. After a delay, Isopropyl
alcohol ignites on contact with dioxgenyl tetrafluorborate, chromium trioxide, and potassium tert-butoxide. When heated to
decomposition it emits acrid smoke and fumes. (Isopropyl alcohol)
Special Remarks on Explosion Hazards:
Secondary alcohols are readily autooxidized in contact with oxygen or air, forming ketones and hydrogen peroxide. It can
become potentially explosive. It reacts with oxygen to form dangerously unstable peroxides which can concentrate and
explode during distillation or evaporation. The presence of 2-butanone increases the reaction rate for peroxide formation.
Explosive in the form of vapor when exposed to heat or flame. May form explosive mixtures with air. Isopropyl alcohol +

BS. It'll burn just fine.
I would use a pump sprayer. You know, one of those gallon or so containers with a spray wand and air pump in the lid.
All I can say is I have tried to ignite 70% rubbing alcohol as as a liquid and have not succeeded .
I have put it on a Q-Tip and it will burn.
So, if you have a wick type set up, you may have a problem.
I would guess it is kind of like gasoline in that the liquid will not burn but the vapor will.
So, as a spray, in a controlled environment, I wouldn’t be afraid of it.
As always, keep a fire extinguisher ready, and your mileage may vary.

Rubbing alcohol is isopropyl. Not particularly flammable. Ethyl alcohol is a different story. The term "proof" came to be used for 50% alcohol, 50% water because at that concentration a dish of it will ignite with a match. So, burning a small amount of your batch provided proof that it was strong liquor - at least 100 proof.
Still, I'm not so sure I'd want to be in a mist or fog of even isopropyl. Outdoors, in the open, on a breezy day ... well, maybe.
