AFI - Air Force Instruction


An Air Force Instruction (AFI) is a policy or guideline issued by the United States Air Force (USAF). Compliance with AFI's is mandatory for U.S. Air Force military forces under the jurisdiction of the AFI's author.

Additional Info

Most AFI's apply to the entire USAF. For example, AFI 90-821 of May 13, 2019 governs the Hazard Communication (HazCom) Program throughout the Air Force. AFI's may also refer to operations or policies at one or more bases.

Members of the U.S. Air Force must comply with national Safety Data Sheet standards and regulations such as 29 CFR 1910.1200 (the OSHA Hazard Communication Standard), but AFI's may supplement those national standards and regulations. AFI's can include chemical labeling, shipping, transport, and/or storage requirements.

AFIs differ from MIL-SPECs which are defense/military standards that outline specific technical performance requirements for items that are manufactured to military requirements/specifications. AFI's are general orders to personnel throughout the specified chain of command whereas MIL-SPECs are specific to particular items used by the DoD. An AFI may, of course, reference one or more MIL-SPECs. For example, the Air Force has AFI's which specify that firefighting foam must meet MIL-PRF-24385F: Fire Extinguishing Agent, Aqueous Film Forming Foam (AFFF) Liquid Concentrate, for Fresh and Sea Water.

SDS Relevance

Safety Data Sheets prepared with the military in mind may occasionally reference AFI's. Some of the more common ones are:
