content: The head scratcher to me is how they defined the hazard here. The product in itself would never cause fire, would it.They should have pointed to poor design or something, but it would not go in flames.

content: What concerns me is that the product is called a "Fire Protection Spray". What the hell is that? Why couldn't they call it a fire extinguisher? Is it because they haven't got the product approved by NFPA or other bodies?It would be like calling a fire blanket a "white kitchen mat".

content: The NFPA recognizes specific categories of fire extinguishers. Foams are commonly used to put out fires, of course (some would say overused, as PFOA fire suppressants have been identified as a pollution problem). But alternatives to AFFF fluoropolymer foams would be useful in many contexts where there is currently no good option. Nuisance cooking fires are a good example. There should be no personal or property risk from a barbeque flare-up: the whole concept of a grill is that flames are present and safely contained. The problem that exists is that the food might be ruined.Foams made from hydrocellulose gels have some ability to absorb heat and smother flames, and could be used in that situation without damage to the edibility or taste of the food. NFPA does not recognize this material (or any nontoxic foam material). So the effect of applying "fire extinguisher" standards to nuisance flame suppression is very much saying "you can't have that".

content: Quote from: Bud on March 13, 2021, 06:12:31 amIndeed the meaning seems to be "creating a hazardous situation".Not a native english speaker, but the way I learned about the word "hazard" is relative to anything that can either create a dangerous situation (such as above) or be in the way of safety (expressions like "road hazard ahead").

content: For my 2c worth... I would interpret it as such...It isNOTa fire-extinguisher as such, but a product that oncesprayed/driedonto some surface, then that 'surface' now resists fire!However, the initial can contents contains some sort ofhydrocarbonchemical too, to act as theinitial propellantfrom the can.Further however, there's a problem with the nozzle etc in initially 'releasing' the contents, so the can itself could still be mostlyfull, (including the probably flammable propellant!), so if disposed of in a fire, it could blow up!

content: Quote from: GlennSprigg on March 14, 2021, 12:30:52 pmWhat you're describing is something different, which is called an intumescent firestop spray. 3M has about a dozen of these for sale.The product in the recall has no propellant (it sprays product from a bag pressurized by surrounding nitrogen inside the can) and does not have any effect when dried, it is a fire smothering foam.
