Air Force‘s minimum safety, fire protection and occupational health standards. Requirements in

this publication are mandatory, unless otherwise indicated. It applies to all Regular Air Force

(RegAF), Air Force Reserve Command (AFRC) and Air National Guard (ANG) military and

civilian personnel. Not included are safety, fire prevention and occupational health requirements

addressed in specific equipment technical orders (TOs). Portions of this standard may apply to

contractors for the protection of AF people and property. Note: MAJCOMs may have more

stringent or restrictive requirements than those contained in this standard or other Air Force

Occupational Safety and Health (AFOSH) publications/standards. Therefore, all requests for

interpretations or clarifications concerning these publications must be forwarded through the

servicing MAJCOM/DRU/FOA safety, health and/or civil engineering organization, as applicable.

Note: With respect to references in this AFI to installation medical treatment facilities, pursuant

to 10 USC 1073c, the Defense Health Agency, a combat support agency, will be responsible for

their administration and management; the details of these responsibilities are still being worked

and finalized.

SUMMARY OF CHANGES

This document is substantially revised and must be completely reviewed. Major changes include

changing this publication to an Air Force Manual, reducing the size of the standard by referring

the reader to Occupational Safety and Health Administration (OSHA) safety standards and other

consensus standards that were previously repeated. Chapters with similar information were

combined to reduce redundancy and streamline requirements; a substantial amount of figures and

tables were removed, and where appropriate, referenced to the original source; and language for

administrative devices, that includes locks and tags not used for hazardous energy control have

been moved to Chapter 29, Mishap Prevention Signs and Tags.

Chapter 1

INTRODUCTION

1.1. Objective.

1.1.1. Occupational Safety and Health Administration (OSHA) safety guidance published in

the Department of Labor (DoL) 29 series Code of Federal Regulations (CFR) provides

employees a safe and healthful workplace. OSHA dictates what must be accomplished in the

workplace, but in some cases, not necessarily how it will be accomplished, or by whom. Refer

to AFSEC Occupational Safety SharePoint site for Introduction to OSHA Standards training

information located at https://cs2.eis.af.mil/sites/10178/Pages/SEGHomeV2.aspx.

1.1.2. Commanders are responsible for the safety of their facilities and personnel, including

the correction of all hazards and deficiencies in their workplaces. This standard compliments

AFI 91-202, The US Air Force Mishap Prevention Program, and assigns responsibilities to

individuals or functions to help Commanders manage their safety and health program, ensuring

they comply with OSHA and Air Force guidance. This standard provides uniform guidance,

which safety staffs and commanders may supplement when additional or more stringent safety,

fire prevention and health criteria are required.

1.2. Variances and Exemptions. The effected work center shall process a request for variance

or exemption when it is impossible to meet AFOSH guidance due to operational needs, mission

impact or technical reasons. (T-1) When requesting a variance or exemption, the work center

leadership must identify and implement interim control measures to reduce the degree of risk

associated with the hazard in order to protect personnel, equipment and/or property. (T-1) The

process for requesting a variance or exemption is provided in AFI 91-202.

1.3. How to Use This Document.

1.3.1. This standard incorporates appropriate parts of the 29 CFRs 1910 and 1926 standards

that relate to Air Force operations. References to other Air Force publications and national

consensus standards are provided as appropriate. Air Force activities must comply with OSHA

requirements at all times, unless the military-unique exemption applies IAW DoDI 6055.01,

DoD Safety and Occupational Health Program, and AFI 91-202. (T-1)

1.3.2. This standard is intended for use by fire, safety and health professionals, commanders,

functional managers, supervisors and employees. The information in this standard is for the

protection of employees, Air Force property and equipment, and to ensure compliance with

Federal law. Note 1: This standard does not apply to state employees. Note 2: This standard

may contain criteria not fully compatible with host-nation safety criteria. In case of conflict,

safety offices shall facilitate coordinated concerns through their hierarchy for resolution.

1.4. Applying Standards. Air Force personnel must comply with all applicable safety guidance

during Air Force operations. (T-1) If, or when, there is conflicting guidance, use the guidance that

provides the most protection for the employee until conflict resolution is attained.

1.4.1. Compliance.

1.4.1.1. This Air Force standard contains both horizontal and vertical fire, safety and

health standards/requirements within the various chapters. Generally, horizontal

standards/requirements apply across all industries/activities; whereas, vertical

https://cs2.eis.af.mil/sites/10178/Pages/SEGHomeV2.aspx


standards/requirements apply to a specific industry/activity, e.g., construction or

telecommunications. There are occupational safety and health mandates contained within

one chapter of this standard which could be interpreted as vertical; however, because safety

rules are established based upon hazards and not just tasks, the mandate may, in fact, be

applied horizontally across several occupations. Example: Confined space requirements

in Chapter 23 – primarily a General Industry application, but may apply to applicable

portions of aircraft maintenance tasks. For this reason, broad guidance cannot be codified

to address all situations. If there is doubt, contact your local safety office for guidance.

Resolve locally, when possible, using risk management techniques focused on the hazard

and hazard mitigation.

1.4.1.2. When AFOSH guidance or other established safety criteria does not cover a

situation, use non-Air Force standards to include, but not limited to, national consensus

standards, professional safety and health standards, and other Federal agency standards.

1.4.2. Occupational Safety and Health Administration (OSHA) Requirements. Air Force

safety officials cannot grant exemptions to OSHA standards, only the Department of Labor has

the authority to grant exemptions to OSHA standards. Refer to AFI 91-202 for additional

guidance.

1.4.3. National Consensus Standards. National consensus standards referenced in this

document have been adopted, in whole or in part, for Air Force use and list the standard,

part/document number, part/document title and date of standard, as applicable, e.g., American

Society of Mechanical Engineers B30.9, Slings, and National Fire Protection Association 70,

National Electrical Code. Personnel needing access to American National Standards Institute

and/or other national consensus standards can contact the installation Occupational Safety

office for guidance and assistance.

1.4.4. Joint Base Safety Standard Compliance. Air Force personnel at Joint Bases will follow

safety requirements outlined in the approved support agreement(s) developed IAW DoDI

4000.19, Support Agreements. (T-1) Conflicts in safety program requirements will first be

coordinated through senior leadership at the local level for resolution. (T-1) If resolution at the

local level cannot be obtained, the unit will refer conflicts to AFSEC/SEG through the

appropriate MAJCOM/FOA/DRU safety office for cross-service resolution. (T-1)

1.5. Job Hazard Analysis (JHA). JHAs are conducted on all work processes, where appropriate,

to identify potential fire, safety or health hazards, determine appropriate personal protective

equipment (PPE) and include preventative measures in procedures to mitigate the hazards. Refer

to AFI 91-202 for additional guidance.

1.6. Military-Unique and Nonmilitary-Unique Policy. The Air Force directive guidance is to

comply with AFOSH, OSHA, DoD and other non-DoD regulatory safety and health standards and

guidance as provided under federal law and IAW DoD policy with respect to military-unique and

nonmilitary-unique workplaces, operations, equipment and systems. Refer to AFI 91-202 for

additional guidance.

1.7. Documentation. This standard specifies use of Air Force Technical Order (AFTO) Form

95, Significant Historical Data, AFTO Form 244, Industrial/Support Equipment Record, or other

appropriate inspection, maintenance and general purpose forms for documenting maintenance and

inspection actions. With expanding use of automated systems for tracking these activities,


requiring specific paper forms may impede use of more efficient automated processes. Therefore,

use of automated systems for documenting inspections, maintenance and other activities is

acceptable in place of specified AFTO Forms 95 and 244 or other appropriate inspection,

maintenance and general purpose forms if they contain the same information called for by the

designated form. Electronic signatures or other unique personal identifiers (not initials) are

acceptable. While this standard offers an optional alternative to paper forms, MAJCOMs, NAFs,

local procedures, Technical Orders (TOs) and other Air Force guidance may continue to require

use of these forms. Check the prescribing directive(s) before discontinuing use of any forms.

1.8. First Aid and Cardiopulmonary Resuscitation (CPR) Training. Initial first aid and CPR

training shall be accomplished prior to assigning an individual duties where first aid and CPR are

requirements of the position. (T-1) All employees requiring CPR training will receive refresher

training before current CPR certification expires. (T-1) Whether by the local Medical Group, the

American Red Cross or other appropriate organization, CPR training shall be provided for unit

instructors, who, in turn, will train unit personnel. (T-1) If CPR training is not provided by the host

medical facility, instructor training shall be obtained from an approved source, e.g., American Red

Cross, American Heart Association, military network, etc. (T-1) Training will also include Public

Access Defibrillator training IAW AFI 44-177, Public Access Defibrillator Program. (T-1) Note

1: Self-aid and buddy care may be used to fulfill first aid training requirements; however, it does

not cover CPR. Employees performing duties with risk of severe cuts, burns or electrocution, or

perform duties in remote locations away from emergency responders will have a plan for

immediate medical response pending definitive transfer and care. (T-0) Note 2: Remote location

is defined as emergency care that is more than three to four minutes from the workplace.

1.9. Bloodborne Pathogen Training. Any person with routine duties where tasks and

procedures involve reasonably anticipated exposure to blood or other potentially infectious

materials (e.g., individual responsible for rendering medical assistance as part of their duties) must

be trained and enrolled in the Bloodborne Pathogen Program IAW 29 CFR 1910.1030, Bloodborne

Pathogen, and AFI 44-108, Infection Prevention and Control Program. (T-0) A person may be

required to receive separate first responder training outside of bloodborne pathogen, e.g., First Aid,

CPR, self-aid buddy care (SABC). For workplaces with employees that meet this job description,

supervisors shall establish a written exposure control plan and conduct training IAW 29 CFR

1910.1030. (T-0)

1.10. Process Safety Management of Highly Hazardous Chemicals.

1.10.1. The Air Force implements 29 CFR 1910.119, Process Safety Management of Highly

Hazardous Chemicals, requirements to prevent or minimize consequences of catastrophic

releases of toxic, reactive, flammable or explosive chemicals. The criteria in 29 CFR 1910.119

shall be used in its entirety for program implementation and application unless otherwise

specified. (T-0) Process safety management also applies to explosives and pyrotechnics, which

are defined in AFMAN 91-201, Explosives Safety Standards.

1.10.2. 29 CFR 1910.119, Appendix A, List of Highly Hazardous Chemicals, Toxics and

Reactives, contains a list of chemicals used in the Air Force, whether the chemical is in a

mixture or a byproduct of a chemical process and/or reaction.
