AFFF Safety Issue

I am glad I decided against AFFF and went with Novec 1230 for my fire system instead.

Lifeline abandoned AFFF and is using a non-toxic, fairly inert ABF for their foam. Turns out the AFFF they were using was not a bad version but decided to change because of the negativity toward AFFF.
We have Novec 1230 in our personal race car and it is by far the best solution.
Since we became a Lifeline distributor 1 month ago, we've converted 10 people from AFFF to either ABF or Novec.

Spoke to the owner at Emergency Suppression Systems as they use AFFF in their systems. He said that the ESS systems only have 3% of the AFFF solution and the rest is water so it is a very minimal amount and not hazardous. If the AFFF product is used at full strength or in huge amounts (like in a naval fire), that can be hazardous.
Good to know there are alternatives out there though for all to consider.

Don't forget we are not fire fighters exposed to AFFF everyday. We might be exposed to 1/2 a bottle in a one off emergency event. Many of us have been racing for years and years and have never pulled that pin. For me it has been 20+ years of racing never to have pulled the pin. Maybe AFFF will be replaced in total and next time we can pick another agent but seems to me the AFFF situation is like getting a chest x-ray and why you get one "if benefits outweigh the risks."

I'm not freaking out over this, but it looks like I have an AFFF bottle in my car... Bob, when you say you've 'converted' 10 people from AFFF to another agent, did you refill their existing bottle w/something other than AFFF or did they need to swap their whole system to a system that uses a different agent (new bottle, compatible plumbing, nozzles etc...)?
Thanks,
Tom

Most are not replacing because of the fear of any harmful effects from AFFF (noted below), but AFFF is a more corrosive than ABF, so if you do 'pull the pin' on AFFF, you really need to clean every single wire and everything and get the residue off. Not nearly as bad as Halon was, but still leaves a slightly corrosive film residue on everything. ABF is inert in that respect.
Novec is so much better because it comes out as a gas vs. foam and dissipates with zero residual. Novec is superior also because of how it disperses. Think about a garden hose - if you're standing in the line of spray, you get wet, if you're off by a few inches, you don't. Same holds for the foam based suppression - it only suppresses fire where it can cover. Novec comes out as a gas and the nozzles spray out everywhere, so it 'blankets the entire area and suffocates the fire more quickly and all over.

I definitely don't want to be poisoned by fire retardant, but for the few (hopefully zero) times I'll be exposed, I wouldn't want to sacrifice retardant effectiveness too much.

Novec is certainly more effective than both.
Another point to Novec - its absolutely inert and safe for electronics. The "A" in AFFF and ABF is "Aqueous", meaning they are both water based. Novec even in liquid form has no effect on electronics. In fact, their demo is they have a clear container of Novec with an iPad submerged in it that works just fine. You can drop you phone in it (I did) with zero effect. And I know from experience that my iPhone does NOT like water...

Here's a quick read that explains some of the differences and properties of AFFF vs. Novec. It's done by Lifeline who at the time sold both.
https://nasaspeed.news/tech/safety/c...-fire-systems/
Personally I feel Novec is a better solution, but we sell far more foam based (AFFF and ABF) systems, mostly due to cost. And again, I've always used Novec for our own cars. Both obviously work fine for what we do, but either way, proper installation is key to effectiveness.

I wonder if Novec vs AFFF and other foam based stack up in terms of reliability. I've heard, granted anecdotally, that some water/foam based systems didn't expel the retardant properly when activated (no information on whether the systems were up to date in terms of maintenance). Are gas based systems more reliable in this regard?

A benefit to gas systems it none of these problems. My concern with those is wind blowing away effectiveness and re-ignition. I can find no data so I have no clue if that's just a baseless personal fear. When foam gets on a fire it's done.

I still miss Halon 1211!
Seriously, I just upgraded to Novec for my sports racing car. Good stuff, worth the money.
