... 28 4.1 Overview AFFF is used in airport operations as a fire-extinguishing agent to prevent, extinguish, or control Class B fires, i.e., fires of flammable and combustible liquids such as crude oil, gasoline, and fuel oils. AFFF generates foam that retains water, separates fuel from flame, and ultimately results in dramatic, fast knockdown of Class B fires.

From page 39...
... aFFF Management Within airport Operations 39 airport firefighting personnel who are involved in firefighting complete at least one live-fire firefighting drill every 12 consecutive calendar months. As per Advisory Circular 150/5210-17C, live-fire drills involve a pit fire with an aircraft mock-up using enough fuel to simulate the type of conditions that could be encountered during a rescue situation at that airport.

... 42 Use and potential Impacts of aFFF Containing pFaSs at airports Handling Follow industry-recommended practices: • NFPA 402: Guide for Aircraft Rescue and Fire-Fighting • Have a safety spill plan in place when transferring containers/testing equipment and systems • So that industry-recommended operational procedures are followed to provide the basis for airport representatives to respond to an aircraft emergency in the minimum possible time and employ rescue and firefighting techniques effectively. Provide personnel training: • Staff is educated in safety and environmental concerns • Staff is trained in standardized procedures designed for safety and environmental concerns • Have two or more people available to move containers with AFFF Require personnel to wear PPE: • Includes but not limited to work gloves, eye protection, safety boots, and protection from contact with skin • To promote awareness of the potential impacts to human health and the environment if the product is mishandled and to provide an understanding of mitigation measures.

... 44 Use and potential Impacts of aFFF Containing pFaSs at airports 4.5.1 Disposal The means by which an airport disposes of AFFF or AFFF concentrate can vary based on the nature of activity resulting in waste for disposal, the nature of the material being disposed (e.g., aspirated residual AFFF, AFFF concentrate, and wastewater containing AFFF or PFASs as a result of vehicle or equipment system maintenance) , an airport's waste management facilities and associated capacity, and applicable regulations.
