Well we did out tests on the Cold Fire product.
We had 6 different burns.
1. Pile of 25 wood pallets
2. Pile of 10 truck tires
3. Single arm chair (upholstered couch style).
4. Furniture stack (love seat, couch, mattress and box spring)
5. 4 door Aries K car
6. Chev 1/2 ton.
Sales gimmicks.
Product is an A, B an D Extinguisher.
Configurations tested
12 oz Aerosol
2.5 gallon extinguisher
Concentrate
Costs 5 US gallon container of Concentrate $279
Cost of Class A 5 gallon $79.00
Sales demos, involved spraying a terry cloth towel with product. Placing a penny in centre and holding it all in your hand, attempt to melt the penny with a torch. Got to hot in sales reps hand before the penny melted. (Cloth was not wet enough).
Demo 2 "Soaked" Cloth in product placed magnesium shavings similar to a Brillo pad on cloth and held in his hand while the Magnesium burned, Successful to ash
We then wanted to use the aerosol to attempt to put out a car fire, Rep said won't do it, 2.5 gallon ext wouldn't do it either.
Test 1: So we decided to light the arm chair and see if it could be put out with the product. 3 aerosol cans and 2.5 gallon extinguisher later the chair was not out.
Personal observation. The aerosol was very limited in volume and the stream out of it was very concentrated and strong. from 6 ft away the stream torn the chair up pretty good and spread burning material into a larger area by it's force, I found this to be a negative as the intention was to make this available to out Seniors for ease of use, how ever into a grease fire this would literally blow the grease all over the place and could potentially promote a much larger fire.
We ended up putting the Chair out with the hand line with product at a 1.5% solution.
Test 2 Pallet fire, good size fire with lots of nooks and crannies in the fuel source Temperature 280 degrees C,
Product was injected a 1.5% into a fog nozzle with a required 30 degree spray pattern. Product was to be lobbed on, Do you have any idea how far away you have to be to Lob a 95 gallon stream on to fire, Impractical, and reps wanted us at 125 gpm, ( we used on on board eductor system to blend the product as we were not about to dump a 50 gallon foam cell to put their product in the tank).
We 1st attempted to use a Med expansion foam tube, Product is not enhanced but hindered using a Foam tube. We the gave up on the lobbing idea and we at it in a normal attach fashion, Work about the same (IMO) as water, on this type of fire, Class A with and expansion tube would have filled all the voids and put this out much faster.
Test #3 Furniture pile:
Again temp reached was around 265 degrees C, Same results as the wood pile, however we were instructed to bring the solution up to 3%, result was the same as wood pile, unspectacular, IMO a .3 class A attack would have rendered better results as opposed to a full 3%
Test 4: Aries K car: Exterior metal at 280C and higher (pyrometer limits are around 290C)
Fully involved till tires blew (what we usually get). As far as putting it out, Unspectacular, Class A at .5% would have been more effective and faster in the actual knock down (IMO). Where the product really shined is in its cooling abilities. Cooled the metal of the vehicle very quickly to 28 degrees where a lot more water would have been used to cool this.
Rep wanted us to batch mix feeling we would have better results, so we had approx 500 gallons in our tank at the time and placed approx 7.5 gallons of concentrate in to our tank and blended in the tank for a 1.5% Solution ( approx).
Test 5: Tire fire fully involved:
Couldn't give a temp over ranged our pyrometer big time. Estimate based on a similar burn earlier in the day approx 500C
3% solution and the Knock down would have been similar to a Class A @ 1%. Again product worked well in it cooling abilities, and very rapidly brought the temp of the materials down. Although smoldering continued due to belt temp it was not hot enough to rekindle.
Test 6: Chev 1/ton reg cab fully involved till all 4 tires used. Accelerant used big time inside, outside, (Simulate arson).
Torched all tires blew and were fully involved, including engine bay.
Results were about the same as the car, Unspectacular when compared to experience with Class A at a 1/3rd of the solution, Again advantage was in the cooling abilities of the product.
Again these are my personal observations and also comparisons are based on my personal experience with Class A fire suppression and usage. I have no financial interest in manufacturers of any fire extinguishing agents and only provide this information based on my observations and comments and discussion about the demo's
Further we set up the evolutions. In now way shape or form did the reps advise us on the Demo's our intention was to attempt to set up situations and burns that as a dept we would encounter along with situations that a civilian may encounter in early stages.
We controlled and did all the fire suppression except for the Arm chair in which the rep attempted to put it out himself.
I have tried to provide a true observation of what we experienced.
Sorry about the long post.
