Firepoint

Ok why is firepoint better than flash point in looking at chemicals??

From Wikipedia, the free encyclopedia

The fire point of a fuel is the temperature at which it will continue to burn for at least 5 seconds after ignition by an open flame. At the flash point, a lower temperature, a substance will ignite briefly, but vapor might not be produced at a rate to sustain the fire. Most tables of material properties will only list material flash points, but in general the fire points can be assumed to be about 10 °C higher than the flash points. However, this is no substitute for testing if the fire point is safety critical. [1]

Fire point is only useful for determining if a liquid is no longer regulated by NFPA 30 or DOT. So trying to use fire point for gases, solids, or other hazard classes like organic peroxides, oxidizers, corrosives, or toxics will not provide you benefit. In fact, if you attempt to perform a fire point test on a organic peroxide or oxidizer, ensure your health insurance is paid and you know the location of closest burn center if you decide to do this beyond the laboratory level. I mention this because you wrote looking at chemicals, and fire point testing is only limited to liquids classified as either flammable or combustible.

Some formulations of flammable or combustible liquid will exhibit a flash point but contain a high concentration of water. This is especially true for many consumer sanitation products. Fire point testing allows one to confirm that combustion will not be sustained for more than 5 seconds even though the liquid exhibits a flash point. If a liquid does not exhibit a fire point, it is exempt from regulation by NFPA 30 and US DOT.

thanks, I wrote firepoint down yesterday and did not reference why?

and what was is it rtech? and saxxon??

and one more web site mentioned hydro bubial?? maybe university of oregan



sorry all the background noise and the waving of the palm trees got me off

You should just walk up and talk to me at seminars.

Next time just ask the question. You saw how I walked around the room because the atrium had horrible acoustics.

You better explain why you posed this question, otherwise it could impact your credibility.

Sorry just could not hear good

And can not spell good, especially some of those Internet names

I did ask questions like the head in the gas cabinet question

Thanks
