Storage shall be listed or designed and constructed to meet the requirements of NFPA 30. Any single cabinet shall contain no more than 454 liters (120 gallons) of Class I, Class II or Class IIIA liquids, of which no more than 227 liters (60 gallons) shall be Class I and Class II liquids. Bulk storage of these liquids shall be in a separate detached building or in rooms specifically designed and constructed to meet flammable storage requirements, i.e., inside smaller paint booth installations.

Vehicle Operations - AFI 91-207

This publication establishes responsibilities, guidance and requirements for the Air Force Traffic Safety Program. Air Force units at all levels must ensure compliance to reduce deaths, injuries, and property damage caused by vehicular mishaps. Other DoD civilian personnel, military retirees, military dependents and long term contractors may attend AF- sponsored training on a space-available basis at no additional cost to the Government.

The owner of a motor vehicle or motorcycle authorized to be operated on an AF installation shall ensure that only properly licensed operators are allowed to operate the vehicle. Commands shall follow host nation, federal, or state licensing procedures including SOFAs.

Tool Control - AFI 91-203

Tool Safety. Unsafe use of hand and power tools can injure workers or damage equipment. Supervisors shall enforce strict tool control procedures. Use of personally owned hand and power tools shall be prohibited. Tools shall be kept in suitable containers when not in use. Appropriate PPE, such as goggles, face shields, hard hats, gloves, respirators and safety-toe shoes, shall be provided to workers and use enforced.

Foreign Object Damage (FOD) - AFI 21-101

FOD: Any damage to an aircraft, engine, aircraft system, component, tire, munitions, or SE caused by a foreign object(s) (FO) which may or may not degrade the required safety and/or operational characteristics of the aforementioned items. All personnel (military, civilian, and contractors) working in, on, around, or traveling through areas near aircraft, flightline munitions, AGE, engines, or components thereof will comply with FOD prevention.

Tobacco Use in the Air Force - AFI 40-102

For Joint Bases where the Air Force is the installation Supporting Component (i.e. Joint Base Andrews-Naval Air Facility Washington, Joint Base McGuire-Dix-Lakehurst, Joint Base Charleston, Joint Base Elmendorf-Richardson, Joint Base San Antonio, Joint Base Langley-Eustis), the Joint Base installation commander shall also implement and enforce the tobacco-free MTF campus at all non-Air Force MTFs. (T-3)

For Joint Bases where the Air Force is the Supported Component (i.e. Joint Region Marianas, Joint Base Anacostia-Bolling, Joint Base Pearl Harbor-Hickam, Joint Base Lewis- McChord), the MTF campus shall be tobacco-free, unless the Joint Base installation commander specifically disapproves in writing.

Hazardous Energy Control - AFI 91-203

Entry into confined spaces, where a non-hazardous atmosphere is maintained through continuous forced ventilation, is a permit-required entry. The intent for reclassifying a permit-required confined space applies primarily to those spaces containing physical hazards, e.g., hazardous energy sources or engulfment hazards. Once the hazards have been eliminated, the space may be reclassified as non-permit as long as the hazards remain eliminated. Elimination is achieved by completely protecting the space against the release of hazardous energy or material into the space.

Confined Spaces - AFI 91-203

Personnel entering or working in confined spaces may encounter a number of potentially serious hazards. These hazards may include atmospheric hazards such as oxygen deficiency insufficient to support life, oxygen-enriched levels that increase the danger of fire or explosion, flammable or explosive atmospheres and materials, or toxic gases or materials. In addition, the confined space may include electrical, mechanical, engulfment or entrapment hazards that must be locked out, or controlled by other means of securing hazardous energy

Safety Investigations and Reports - AFI 91-204

Safety Report—Safety reports include message reports (preliminary, status, and final), formal reports, and injury and occupational illness forms and logs.

Aviation Flight Mishap—Any mishap in which there is intent for flight and reportable damage to a DoD aircraft. Explosives and chemical agents or guided missile mishaps that cause damage in excess of $20,000 to a DoD aircraft with intent for flight are categorized as aircraft flight mishaps to avoid dual reporting. This is the only aviation mishap subcategory that contributes to the flight mishap rate.

The lead MAJCOM/A3 will brief and advocate SIB recommendations at the flight manual and technical order review boards. For Aviation Class A and B mishaps, if recommended changes are disapproved by the flight manual or technical order review boards, the appropriate directorate will brief MAJCOM/CV on disapproval rationale at the mishap review panel (MRP) and the MAJCOM/CC or CV will accept the risk of not implementing the safety recommendation. However, the MAJCOM/CC or CV may direct the implementation of a safety recommendation regardless of the flight manual or technical order review board’s decision.

USAF Traffic Safety Program - AFI 91-207

Some requirements addressed in this Instruction may be the responsibility of the host or supporting service, installation or wing through an official Support/Operating Agreement, MOU or MOA, and/or SOFA. Ensure enforcement of all traffic rules to include speed limits, use of occupant restraints, driving under the influence, and distracted driving.

Promote individual risk management (RM) and other requirements of this Instruction.

General Industrial Operations - AFI 91-203

The criteria in this standard are the Air Force’s minimum safety, fire prevention, and occupational health requirements for general industrial operations. Major commands (MAJCOM), direct reporting units (DRU), and field operating agencies (FOA) may supplement this standard when additional or more stringent safety, fire prevention, and health criteria are required. This standard does NOT apply to contractors working on Air Force installations, including contractors who use government-furnished equipment and facilities. They are responsible for the safety and health of their personnel. Contractors may choose to follow all or parts of this standard, but it is not mandatory for the protection of the employees.
