Micro-Blaze Out is a UL-classified Class A & B wetting agent under NFPA 18, non-toxic, biodegradable, PFAS-free. Micro Blaze+2Micro Blaze+2
Recommended application / proportioning:
- Structures (Class A) – 1% solution
- Tires / vehicles (Class A/B) – typically also 1%
- Liquid hydrocarbon spill fires (Class B) – 1–3%, often 3% for active burning. Micro Blaze+2Micro Blaze+2
Other product literature notes Class A use at 0.5–1% and Class B at 2–3%. Microblaze.ca+1

For a standard 2.5-gallon PWC, here’s what that looks like:

2.5 gallons × 1% = 0.025 gallons of concentrate
0.025 gal × 128 fl oz/gal ≈ 3.2 fl oz

So practically:

1% mix (solid “structural Class A” setting):
→ 3 oz of Micro-Blaze Out per 2.5-gallon can
If you want to run a “lighter” Class A mix to reduce sudsing but still get benefit:
- 0.5% → ~1.6 oz per can
- 0.75% → ~2.4 oz per can

Most departments that use these kinds of additives in cans land in that ~2–3 oz range. I’d default your teaching to:

“Add about 3 oz of Micro-Blaze Out to a full 2.5-gallon pressurized water can (≈1% mix) unless your department’s SOP or the Micro-Blaze rep says otherwise.”

Why add Micro-Blaze to the can?

Here’s the “why” you can drop into a bathroom trainer sheet:

Better fire performance on Class A materials
- Micro-Blaze Out acts as a wetting agent – lowers water’s surface tension so it penetrates deeper into porous fuels (furniture, bedding, wall cavities) and improves cooling and knockdown vs plain water. Perimeter Solutions+2US Forest Service+2
Helps with Class B spills / mixed fuel messes
- UL-classified for both Class A and Class B, and specifically marketed for hydrocarbon spill fires and vehicle/industrial incidents. Micro Blaze+2Micro Blaze+2
- That’s handy when your “water can” ends up pointed at a fuel-contaminated Class A situation (cars, shops, kitchens with grease/fuel involvement).
Microbial clean-up and reduced environmental headache
- Contains Bacillus microbes + surfactants that digest hydrocarbons and other organics in the runoff, helping to prevent reignition and making the residue more treatment-plant-friendly. Micro Blaze+2Micro Blaze+2
- Marketed as PFAS-free and accepted at wastewater plants, which is a selling point when you’re trying to get away from legacy foams. Micro Blaze+1
Operationally: more punch in a small package
- When you combine the efficiency of wetting agent water with the mobility and visibility of the can, you get a very strong tool for:
  - Quick knockdown during search
  - Holding a hallway or doorway while the line is stretched
  - Small overhaul jobs (cushions, mattresses, trash, small wall/ceiling openings)
