What Is Class B Foam and How Is It Used in Firefighting?
As a firefighter, understanding and using firefighting foams is crucial in saving lives and protecting property. Let’s focus on something called Class B foam, a superhero in dealing with nasty situations like gasoline spills, oil blazes, and those pesky jet fuel fires. This stuff’s got the power to put a lid on high-risk flammable liquid fires.
Digging into what makes Class B foam tick is vital when up against fires fed by petroleum or alcohol. Basically, this foam works by forming a barrier between the fuel and the air, essentially telling the fire, “Nope, not today!” You’ve got two versions: one for water-loving materials (polar) and another for oil-based foes (nonpolar). Each type’s made with a specific mission in mind.
To get a real grip on Class B foam, we’re going to look at how it’s actually used when the emergency lights are flashing. We’re not sweeping under the rug the health and environmental questions people have. Plus, greener firefighting resources are stepping up to the plate, and there’s plenty to say about that legal mess over Aqueous Film Forming Foam (AFFF) exposure. If you’ve been around this stuff and are thinking of compensation claims, we’ll brush up on that too.
Amidst all this foam talk, it’s key to remember how firefighting methods keep getting better, aiming to keep firefighters safe while being kinder to our planet.
What is Class B Foam?
Firefighting’s secret weapon when you’re dealing with flammable liquids like gasoline or jet fuel. This so-called Class B foam, formally known as Aqueous Film Forming Foam (AFFF), has properties that make it indispensable in taming high-hazard fires effectively.
Chemical Skills and How It Does the Trick
Class B foam is like the genius of the firefighting world, usually whipped up using substances called Per- and Polyfluoroalkyl Substances (PFAS). It’s the magic in these ingredients that give it super powers to squash fires fueled by flammable liquids.
The magic trick with Class B foam is its ability to lay down a slick protective film over the surface of the liquid that’s on fire. This film acts like a barrier, cutting off the fire’s oxygen supply from the air. One thing to keep in mind: for this protective film to do its job well, you need to have the fuel behind some kind of barrier or contained, giving the film a chance to spread out and work its magic.
Types of Class B Foam: AFFF vs AR-AFFF
You’ve got your options when it comes to fighting liquid fires, with a couple different types of Class B foam concentrates to choose from. Each one’s got a knack for dealing with specific types of fires. Let’s talk basics:
- AFFF Foam: This is your go-to for the usual trouble-makers: hydrocarbon fires from petroleum and polar solvent fires, like things involving alcohol. Known for getting the job done quickly, it’s highly useful in plenty of flammable liquid situations.
- AR-AFFF Foam: When dealing with alcohol-based fires, AR-AFFF steps up. It’s specifically designed to resist being dissolved by alcohol, something traditional AFFF might struggle with.
By getting the hang of the chemistry and differences within Class B foam, firefighters can pick the right foam for the job. Want to dive deeper into the potential effects of AFFF and how it might shake up firefighting? Take a look at our piece on what is AFFF exposure.
How Class B Foam Is Used in Firefighting
As a firefighter, getting the hang of Class B foam is the name of the game when battling blazes involving flammable liquids and gases. These fires, dubbed Class B, bring their own bag of tricks and require special extinguishing agents since water’s about as useful as a chocolate teapot with these guys. Let’s break down how Class B foam steps up to the plate in firefighting situations, like tackling flammable liquid fires, and its role in industrial and military worlds—as well as the slick techniques used for deploying it.
Suppressing Flammable Liquid Fires
Class B fires are notorious for kicking off with stuff like propane, gasoline, oils, and solvents. Throwing water on these types of fires can be like throwing gasoline on a grease fire—not your best move. To hit the bullseye with Class B fires, firefighters whip out the big guns—special extinguishers like dry chemicals, aqueous film-forming foam (AFFF), and others that can get the job done without the splashy drama.
Class B foam is a real champ here. It throws a protective blanket over the burning fuel, cutting off its oxygen and giving it no chance to flare back up. This “night-night” move on the flames snuffs them out by starving them of air and keeping everything on lockdown.
Industrial and Military Applications
Class B foam isn’t popping up just in the regular firefighting playbook. It’s a must-have on the industrial and military stage. Places like refineries, chemical plants, and aviation venues count on Class B foam like lifeline on their worst days. The military’s not left out—they pack Class B foam for extinguishing rogue fires in combat zones, during drills, and in spots where fuel stack up like nobody’s business.
In these heavy-duty environments, Class B foam is a top player—keeping folks, property, and mission-critical gear outta harm’s way.
Firefighting Techniques and Deployment Methods
When it comes to wrangling Class B fires with the foam, firefighters have a set of moves that might as well be trademarked. Knowing how flammable liquids act up and the knack for managing foam application can make or break the mission’s success. The trick is to lay down a thick-enough foam cover over the liquid sea to stamp out any chance of reignition.
And for deployment that’s as sharp as it gets, tools like compressed air foam systems (CAFS) come into play, amping up foam efficiency while keeping Mother Earth happy. Thanks to these methods and top-shelf tech, firefighters can do what they do best—tame, control, and quench fiery beasts with some serious flair.
By honing the skill of using Class B foam, firefighters aren’t just fighting fires—they’re defending lives, safeguarding what matters, and keeping their communities safe as houses. Through grit, smarts, and unwavering safety drills, they wield Class B foam with the savvy of pros, cutting the risks tied to flammable liquid fires across the board.
Environmental and Health Concerns of Class B Foam
Working around fire and hazardous liquids, it’s pretty clear that Class B foam not just douses flames but comes with its share of hiccups, especially with Per- and Polyfluoroalkyl substances (PFAS) making headlines. Know what these chemicals bring to the table and how the rules for Aqueous Film Forming Foam (AFFF) are shaping up.
The Impact of PFAS and Toxic Chemicals
Think Class B foam, think Aqueous Film Forming Foam (AFFF) and bam! PFAS pops up. These strong chemicals love to stick around in the environment and they’re no friends to your health. When firefighters spring into action using these foams on volatile blazes like jet fuel and gasoline, it might seem like a victory, but actually, traces of PFAS are sneaking into the land and water we need to safeguard.
Want to know if a foam has PFAS? Hunt down words like “fluorosurfactant,” “fluoroprotein,” “C6,” or anything “fluoro” flavored. A good old chat with the foam-maker or a look at their Safety Data Sheets (SDS) can spill the beans on whether there are PFAS lurking around. Getting the lowdown on what you’re working with can keep those chemical troubles at bay.
Regulations and Bans on AFFF Foam
As the bells ring louder about PFAS hazards, cutting back on AFFF lots has become a hot topic. Back in 2020, rules popped up that nudged fire departments to keep a tight leash on Class B AFFF foam usage and spill the beans on its use. Helping both planet and people by reining in PFAS spread is the name of the game here.
Take a note from Michigan’s book—they rolled up their sleeves with their statewide Class B AFFF Pickup and Disposal Program, hauling off a whopping 60,000 gallons of AFFF by 2023. It’s about tackling PFAS head-on, showing that dealing with these foams right can make quite a dent.
Keeping tabs on evolving guidelines and pitching in on disposal gigs can help tune down the environmental and health irritations from Class B foam. By sticking to what’s right according to the big folks in charge and making savvy choices about AFFF’s life cycle, those in the firefighting gig can really step up for a cleaner, greener scene.
Safer Alternatives to Class B Foam

The big headache with traditional foams like Aqueous Film Forming Foam (AFFF) is those pesky perfluorochemicals (PFOAs and PFOCs) which can mess up our surroundings. To curb this, many firefighting squads are making the switch to fluorine-free foams. These do their job without the PFAS (per- and polyfluoroalkyl substances) nastiness, offering a greener solution. So, you get to knock out those liquid fires while giving a thumbs-up to Mother Nature.
Best Practices for Eco-Friendly Fire Suppression
Going fluorine-free is a fantastic start, but you can crank up the green by following some eco-minded fire suppression tricks. Trying compressed air foam systems can nail down environmental damage, as they create a neat foam blanket trapping the fire while keeping the nasty stuff from reaching the earth.
For Class B foam, especially AFFF, it’s all about being smart with the stream. Placing it just right can make a huge difference, protecting the area from fumes and making every drop count. Strategic moves like bouncing the foam off nearby structures form a crucial barrier, keeping vapors locked in, and upping your firefighting efficiency.
Staying in the loop with the latest rules and guidelines about foam is a must for all firefighters. From fire chiefs to rookies, everyone should report how they use Class B stuff, especially when it involves AFFF. Sticking to official procedures helps cut the environmental footprint of fire fighting and paves the way for safer practices across the board.
By shifting to safer alternatives and continuously updating firefighting techniques, we tackle liquid fires efficiently while ensuring the health of our planet and ourselves. Going with fluorine-free options and adopting eco-friendly methods encourages a responsible and sustainable firefighting culture that’s good for everyone involved.
