The National Fire Protection Association (NFPA) has limited use of these liquids in fire sprinkler systems because when the proportion of the active ingredients near a sprinkler becomes too high relative to water, an antifreeze solution can actually serve as fuel for a fire when the sprinkler discharges.

How do I protect my fire sprinkler system from freezing?

To keep the water inside the pipes of a wet fire sprinkler system from freezing in areas where the temperature may drop below 50 degrees, an antifreeze loop is added. By adding antifreeze to the water in the fire sprinkler pipes, the freezing point is much lower, reducing the risk of the pipes freezing.

How do I fill my sprinkler system with antifreeze?

How to Fill an Antifreeze Sprinkler System

  1. Find out how much liquid you need to fill the antifreeze loop of your sprinkler system.
  2. Mix with water the amount of antifreeze you need to make its freezing point below the coldest possible temperature in your area.
  3. Locate the fill cup and drain valve for the antifreeze loop.

Is waterless coolant flammable?

On balance, Evans Waterless Coolants are not more fire-prone than standard water-based antifreezes. Neither antifreeze concentrate (without water) nor water-glycol antifreeze coolant is likely to be a first-fuel in a vehicle fire, but both can be ignited.

What happens if you burn antifreeze?

A coolant mix of water and ethylene glycol based anti-freeze in the presence of these high temperatures will decompose the water out of solution and the remaining ethylene glycol may undergo auto-ignition. The resulting fire may be similar to an alcohol fire, resulting in a blue flame.

Is antifreeze classed as flammable?

Is Antifreeze or Coolant Flammable? Yes, antifreeze is flammable. This includes both ethylene glycol and propylene glycol. In fact, according to JCM Machine & Coatings, there have been a fair number of engine fires that have been clearly caused by the auto-ignition of antifreeze within the engine.

Are Ice engines flammable?

Engine Coolant is it Flammable. I contacted a good friend of mine to get the low down on its flammability or ignition temperature.

What color does antifreeze burn?

White/Gray Exhaust: White exhaust smoke is an indication that coolant is burning in the combustion chamber.

What color is fuel smoke?

Black Smoke From Tailpipe This typically indicates a rich fuel condition in the engine. A fuel mixture that’s described as “rich” means that a ratio of too much fuel to not enough air is being burned in the engine. The unburned gasoline fumes exit via the tailpipe as black, acrid smoke.

What color smoke is unburnt fuel?

White smoke

What causes engines to smoke?

Smoke often leaves car engines as a result of overheating. This can be caused by faulty wire casings, heated residues on the engine block and overheated liquids including oil, transmission fluid and brake fluid. There may also be a fault in your coolant system, or your engine may not have enough lubricant.
