Aqueous Film-Forming Foam (AFF)
Aqueous Film-Forming Foam (AFF) is a highly effective synthetic firefighting foam concentrate designed to extinguish flammable liquid fires (Class B) by forming a water-based film that rapidly cuts off oxygen and halts vapor release. Modern formulations are increasingly fluorine-free (PFAS-free), providing high-performance fire suppression while addressing significant environmental and health concerns associated with legacy PFAS-containing foams. It is used in fixed systems and portable equipment across aviation, maritime, petrochemical, and industrial sectors.

6. Environmental & Health Impact
- Biodegradability: PFAS-free formulations are readily biodegradable. Legacy PFAS foams are non-biodegradable.
- Ecotoxicity: PFAS compounds are persistent, bioaccumulative, and toxic (PBT). Fluorine-free foams present a significantly lower environmental hazard.
- Persistence: PFAS are "forever chemicals" with indefinite environmental persistence.

Safety Handling Precautions
- PPE Required: Chemical-resistant gloves (nitrile), safety goggles, and protective clothing.
- Handling Guidelines: Prevent spills. Do not contaminate water sources. Handle in well-ventilated areas.

First Aid Measures
-
- Inhalation: Move to fresh air.
- Skin Contact: Wash thoroughly with soap and water.
- Eye Contact: Rinse immediately with plenty of water for 15 minutes. Seek medical attention.
- Ingestion: Rinse mouth. Do NOT induce vomiting. Seek medical advice.
Firefighting Measures
-
- Fire Hazards: Not flammable, but exposure to high heat may produce hazardous decomposition products.
- Extinguishing Media: Use water spray to cool containers and dilute spills.
- Special Precautions: Firefighters must use SCBA. Combat fire from a safe distance.
- Hazardous Combustion Products: May include carbon monoxide, carbon dioxide, hydrogen fluoride (from PFAS foams), and aldehydes.
