Flight Standards Service Aircraft Accident Investigation Safety Program

The Flight Standards Service (AFS) Aircraft Accident Investigation Safety (AAIS) Program is an element of the AFS Occupational Safety and Health (OSH) Program and establishes the minimum requirements for AAIS and respiratory protection for AFS employees. This program outlines the requirements that must be met to achieve an effective AAIS Program, and includes the requirements for an effective Respiratory Protection Program (RPP).

Local field office management may develop an office-specific AAIS Program as long as it meets all of the minimum requirements in this order.

The requirements detailed in this document are based on applicable portions of Occupational Health and Safety Administration (OSHA) regulations under Title 29 of the Code of Federal Regulations (29 CFR) parts 1904, 1910, and 1926; the current editions of Federal Aviation Administration (FAA) Order 3900.19, Occupational Health and Safety Program, and FAA Order 8020.11, Aircraft Accident and Incident Notification, Investigation, and Reporting; and industry consensus standards. AFS management and employees must implement the requirements found herein.

Aircraft accident investigations involve safety requirements from several disciplines, including respiratory protection, fall protection, hearing conservation, hazardous materials (hazmat) safety, and general industry safety standards. This order supplements more specific information included in other AFS OSH programs, and it includes policies and procedures for protection against potential hazards encountered at an aircraft accident scene. However, the requirements regarding bloodborne pathogens (BBP) can be found in the AFS Bloodborne Pathogens Program Order located on the AFS OSH Program Web page (https://my.faa.gov/go/AFSOSH).

The training associated with this AAIS Program will be available within 12 months of the date of this order. The field offices will be notified of the train-the-trainer classes via their regional OSH point of contact (POC).

c.    Provide guidance as to the frequency of medical evaluations for various employees.

Chapter 3.  AAIS Program Requirements

1.    Unsatisfactory Condition Reports (UCR).

a.    Background. No employee is expected to perform work activities that subject him or her to an unsafe or unhealthful work condition. If an inspector is potentially exposed to a safety hazard, he or she must not perform the task until the hazard is remediated. If it cannot be corrected or there are no alternate measures that can be taken to address the hazard, the inspector must not complete the activity and inform his or her Front Line Manager (FLM) of the situation.

b.    UCR Reporting. Preferably, the inspector should discuss the hazardous condition with the supervisor to abate the unsafe condition. However, any employee or employee representative who believes that an unsafe or unhealthful working condition exists shall have the right to make a report of the unsafe or unhealthful working condition to an appropriate agency safety and health official and request an inspection of the workplace.

c.    Filing a UCR. A UCR may be submitted electronically or in writing on FAA Form 1800-1, Unsatisfactory Condition Report. The electronic UCR form can be found in the intranet favorites under Aviation Safety (AVS) Resource Links or by going to https://smis.faa.gov/UCR/UCR_user_prompt.asp. Refer to the current edition of FAA Order 1800.6, Unsatisfactory Condition Report, for further instructions.

2.    Scope of FAA AAIS Responsibilities. When the National Transportation Safety Board (NTSB) is not participating, the FAA controls the accident scene for preservation of evidence and/or to determine its nine areas of responsibility, but does not control the safety of non-FAA personnel at the scene.

3.    Hazard Identification and Control.

a.    Identification of Aircraft Accident Investigation Site Hazards. Aircraft accident investigation sites often present many different types of hazards, requiring careful analysis and preparation by AFS investigators prior to site entry. The following are some of the more common types of aircraft accident investigation site hazards. See Appendix A, AAIS Program Definitions, for AAIS Program-related definitions. Appendix B, Hazard Analysis, presents additional detail on aircraft accident site hazards.

(1)    Human Biological Hazards. Bloodborne pathogens (BBP) from crash victims or from air ambulance aircraft (refer to the AFS Bloodborne Pathogen Program Order located on the AFS OSH Program Web page (https://my.faa.gov/go/AFSOSH) for more information).
(2)    Environmental Biological Hazards. Disease-bearing insects, venomous reptiles/spiders, dangerous animals, plants, etc.
(3)    Chemical Hazards. Explosives, flammable gases, liquids and solids, toxic or corrosive substances, etc.
(4)    Radioactive Hazards. Medical cargo, etc.
(5)    Electrical Hazards. Power lines, generator power cords, etc.
(6)    Slips, Trips, and Fall Hazards. Muddy ground, open doors, lifts, entanglement hazards from aircraft wiring, etc.
(7)    Mechanical Hazards. Salvage crew’s equipment, power tools, etc.
(8)    Noise Hazards. Generators, ground vehicles, aircraft engines, power tools, etc.
(9)    Physical Hazards. Ground vehicles, falling debris, jagged metal debris, etc.
(10)    Temperature, Visibility, Altitude, and Weather Hazards. Cold and hot weather, altitude hazards, ice, snow, other precipitation, reduced visibility at night and fog, etc.
(11)    Impact Area Hazards. Crash into a building with chemicals, asbestos, etc.; crash into a swamp area, site with accessibility difficulties, terrain, etc.

b.    Hazard Control Measures. Appendix C, Hazard Control Measures, provides additional details about aircraft accident site hazard control measures.

(1)    Elimination. Hazard elimination involves removing the hazard from the workplace or allowing the work to be done from a safe distance. Although this is the preferred hazard control measure, due to the nature of an AFS inspector’s job, this is not always possible. If it is not possible, the inspector must employ other methods to mitigate hazards.
(a)    Inspectors and their supervisors must exercise good judgment when determining the need to execute tasks that present significant hazards that cannot be eliminated.
(b)    Practical examples of hazard elimination measures include waiting at a safe distance until fires are extinguished, waiting until a coroner removes bodies and body parts, and waiting until a hazardous materials (hazmat) crew removes hazardous cargo.
(2)    Engineering Controls. If the hazard cannot be eliminated, using engineering controls is the next‑best measure to control the risk. An example is shielding noisy generators at worksites.
(3)    Administrative Controls. Work procedures can occasionally be adjusted to mitigate accident site hazards. For example, during hot weather, the inspector should schedule frequent breaks to reduce the potential for heat injuries, especially when wearing protective clothing. In some cases, administrative controls can be combined with elimination measures or use of PPE.
(4)    PPE. PPE shall be used after other control measures are determined not to be practical or as a supplement to existing administrative and engineering controls.

4.    Inspection of AAIS PPE.

a.    Before Entering an Investigation Site. Inspectors must visually inspect AAIS PPE prior to entering an aircraft accident investigation site. Never assume that AAIS PPE is safe for use without an inspection.

b.    PPE Inspection Checklist. Appendix D, Personal Protective Equipment (PPE) Inspection Checklist, includes an inspection checklist for aircraft accident investigation go-kit PPE, and provides a concise checklist for AFS inspectors to use prior to deploying on aircraft accident investigations to ensure that PPE is functional and safe to use.

5.    Injury/Illness Prevention Systems for Aircraft Accident Investigation.

a.    Site Assessment.

(1)    When an inspector arrives at the accident site, he or she needs to gather as much information as possible from the first responders, including, but not limited to:
(a)    Number of victims, location of bodies and/or body tissue/fluids, and if any information is known about their health.
(b)    Location of debris trail and is any of the debris overhead, etc.
(c)    Information on cargo, chemicals, electrical hazards, environmental concerns, etc.
(d)    Wind direction, fuel spills, and areas with burnt composites.
(2)    After gathering as much information as possible, the inspector should perform his or her own personal assessment of the safety hazards of the scene and work with other site stakeholders to post signs, flags, etc., marking the primary hazards.
(3)    Based on this assessment, the inspector must don the appropriate PPE for the hazards expected.

b.    Biological, Chemical, and Radiation Hazard Protective Measures.

(1)    Protective Clothing and Respirator Ensembles.
(a)    OSHA PPE standards for hazmat are based on four levels of protection: A, B, C, and D.

1.    The AVS Standardized Go-Kits for accident investigation contain the applicable PPE for accident investigation safety. This PPE has been reviewed and approved by OSH professionals as the appropriate PPE for AFS participation in aircraft accident investigations based on information gathered from hazard analyses.

2.    Hard hats, safety toe boots (refer to the AVS Standard Operating Procedure (SOP) for Selecting and Obtaining Foot Protection (https://my.faa.gov/content/dam/myfaa/org/linebusiness/avs/programs/oshw/policy_guidance/AVS_SOP_FootProtection.pdf), and eye protection (safety glasses or goggles) are included in all four ensembles.

3.    Protection Level A requires fully encapsulating protective suits, and Level B requires a slightly lower level of encapsulation. Both Levels A and B require supplied air respirators, inner and outer gloves, and inner and outer boot covers. AFS inspectors will not enter sites requiring these levels of protection. If a site requires these levels of protection, AFS inspectors must wait until hazmat experts remove or mitigate the hazards.

(b)    AFS inspectors may enter sites requiring Level C and D ensembles. Level C consists of a protective coverall, an air-purifying respirator (APR) with appropriate cartridges or filtering facepiece, inner and outer gloves, and inner and outer boot covers. Level D consists of a coverall and work gloves, plus the hard hat, eye protection, and safety toe boots included in all four ensemble levels.
(c)    AFS accident site inspectors usually work in Level D ensembles, but they will be trained, equipped, and prepared to work in Level C ensembles. The AFS AAIS training will include hazmat awareness. They must also complete a respiratory questionnaire, per Chapter 4 of this order.
(2)    Site Hazard Procedures.
(a)    Site Zones. AFS inspectors may encounter an incident command system at aircraft accident investigation sites. AFS inspectors may be required to report to an incident commander and/or safety officer upon arrival at the site. The inspector is required to follow established protocol and/or safety procedures, if established.

1.    If the AFS inspector is the inspector-in-charge (IIC) for the accident scene, he or she needs to notify other authorized entry personnel of their site assessment and potential hazards.

2.    In some cases where hazmat is involved, the incident commander may establish hot, warm, and cold zones.

·    The hot zone is or may be contaminated. Entry will be limited to those with appropriate PPE and training, plus a need to be in the hot zone.

·    The warm zone is for worker decontamination when exiting the hot zone.

·    The cold zone is where all other activities occur and is outside the contaminated area.

(b)    Initial Isolation and Protective Action Distances. The U.S. Department of Transportation (DOT) has established initial isolation and protective action (evacuation) distances for most hazmat in the Emergency Response Guidebook (ERG) (which can be downloaded off of the Pipeline Hazardous Material Safety Administration (PHMSA) Web site: http://www.phmsa.dot.gov). If hazmat is involved in an aircraft accident, AFS inspectors shall work with the incident commander or other first responders to coordinate AFS responsibilities with ongoing isolation and evacuation efforts.

c.    Electrical Hazard Preventive Measures. Some aircraft accidents involve impacts with electrical sources, such as power lines, power poles, communications equipment towers, lighting towers, and other electrically powered equipment. AFS inspectors must wait to enter the area until an authorized person has appropriately mitigated the electrical hazards.

(1)    While working at field investigation sites, AFS inspectors may encounter power cords leading from generators to power tools or light stands. These cords present potential electrocution and trip hazards, especially at night or during wet weather. Awareness, a flashlight, and a good pair of rubber-soled boots will help mitigate these hazards. Power cords should be covered with protective shields in traffic areas to prevent damage to the outer insulation.
(2)    When working at forensic reconstruction facilities, AFS inspectors shall obtain a pre-entry safety briefing that should include information about site-specific electrical hazards and the facility’s lockout/tagout electrical source safety program.

d.    Fall Prevention Systems. AFS inspectors may encounter fall hazards at field sites and forensic reconstruction facilities. Inspectors will complete AFS Fall Protection Program training. Prior to using fall protection PPE provided by host employers, AFS inspectors will visually inspect the PPE using the procedures stipulated in the AFS Fall Protection Order and the Fall Protection User level training. AFS inspectors may request fall protection PPE from the Field Office Fall Protection Program Administrator (FO-FPPA).

e.    Hearing Conservation. AFS inspectors commonly encounter noise hazards with sound pressure levels capable of damaging hearing at aircraft accident investigation sites. Whether enrolled in the AFS Hearing Conservation Program or not, all AFS inspectors should carry ear plugs and/or ear muffs to accident investigation sites. Sound pressure level monitoring will not be available at every aircraft accident investigation site. As a rule of thumb, inspectors should don their ear plugs or muffs when noise levels require a raised voice in order to be heard.

6.    Training. When combined with appropriate hazard elimination, engineering controls, and PPE, training can reduce the number of injuries, illnesses, and fatalities at aircraft accident investigation sites.

a.    AFS-Specific Training Courses. AFS inspectors who respond to aircraft accidents must complete the following AFS-specific training courses:

(1)    AAIS Program training, which includes:
(a)    Hazmat awareness,
(b)    Radiation awareness,
(c)    Respiratory protection, and
(d)    Processes and AFS-specific procedures for site safety.
(2)    BBP training, per the AFS Bloodborne Pathogen Program Order located on the AFS OSH Program Web page (https://my.faa.gov/go/AFSOSH).
(3)    Fall protection training, per the current edition of FAA Order 3900.65, Flight Standards Service (AFS) Fall Protection Program (FPP) (either User or Program Administrator level).
(4)    Hearing conservation training, per the current edition of FAA Order 3900.66, Flight Standards Service Hearing Conservation Program.

b.    First Aid Training. If suffocation, electrocution, fall, or amputation hazards are present at the aircraft accident site, the employee must delay his or her entry into the site until a person with first aid training is on site.

c.    Documentation of Training. All training shall be properly documented in the student’s learning history in the electronic Learning Management System (eLMS). Documentation of training shall also include a sign-in sheet that contains the printed name and signature of the employee, the date of training, and the signature of the qualified person who performed the training.

7.    Acquisition of Aircraft Accident Investigation Site PPE.

a.    PPE Procurement. It is the responsibility of field office management, with consultation from the AFS OSH Office, to determine the need for and acquisition of AAIS protective equipment for their employees.

b.    Obtaining Go-Kits and Replacements. Field offices must work with the AAIS-PM and/or the AFS OSH Office to obtain the standardized go-kits and replacement items.

c.    OSHA and American National Standards Institute (ANSI) Standards. All equipment selected shall meet applicable OSHA and ANSI standards and must be suitable for the work intended. The AFS OSH Office and the AAIS-PAs should be consulted to aid in the selection of AAIS equipment.

Chapter 4.  Respiratory Protection Requirements

1.    General. This chapter addresses respiratory protection at aircraft accident sites and areas related to accident investigation.

2.    Respirator Types and Selection.

a.    Respirator Types.

(1)    Filtering Facepiece Respirators. These are effective against particulates, biohazard aerosols, and different types of other aerosols (e.g., the P100 is effective against paint, petroleum, and hydraulic aerosols, while the N95 is not).
(a)    They are routinely referred to as dust masks, but they are more efficient and more advanced than a dust mask.
(b)    They require medical clearance and fit testing per OSHA.
(c)    They are disposable and easy to wear.
(2)    Air-Purifying Respirators (APR).
(a)    These are tight-fitting respirators that require cartridge management, including replacing and paying attention to when the cartridges get full and ensuring that the cartridge is designed for use with that manufacturer’s respirators.
(b)    They require medical clearance and fit testing per OSHA.
(c)    They are not as disposable as filtering facepiece respirators.
(d)    They are not as comfortable to wear for most people.
(e)    Some are powered (Powered Air-Purifying Respirators (PAPR)).

b.    Respirator Selection.

(1)    AFS respirator selection is based on qualitative and quantitative assessment of aircraft accident scenes, burn testing, and possible inhalation exposures, including findings from hazard analyses performed for the activity.
(2)    The AAIS training will include historical AAIS data on typical activities and provide scenarios where different types of respirators are required for specific activities and/or hazards.
(3)    Accident go-kits shall contain P100 filtering facepiece respirators that can be used for most air contaminants at an accident scene. Field personnel will be trained when the filtering facepiece respirators will be sufficient and when a half-face APR will be needed.
(4)    All selected respirators shall be certified by the National Institute for Occupational Safety and Health (NIOSH), and all filters, cartridges, and other media shall have the appropriate NIOSH approval label.
(5)    All respirators and equipment shall be provided at no cost to the employee.

3.    Authorized Respirators and Medical Evaluation.

a.    Authorized Respirators.

(1)    The following types of respirators are authorized for use by AFS:
(a)    N95 for BBP protection filtering facepieces.
(b)    P100 filtering facepieces for aircraft accidents.
(c)    Half-face APRs.
(2)    An office shall not assign or procure any other type of respirator unless it informs the AFS OSH Office and receives written AFS OSH Office authorization, and employees are properly fit tested with that model respirator prior to use.
(3)    AFS personnel are prohibited from using self-contained breathing apparatus (SCBA) or other atmosphere-supplying respirators, which include airline (also called supplied air) respirators.
(4)    AFS employees shall not engage in an operation or enter an area where atmosphere-supplying respiratory protection is required.
(5)    APRs shall not be used:
(a)    In potentially oxygen-deficient atmospheres,
(b)    In immediately dangerous to life or health (IDLH) conditions,
(c)    When hazards could be present for which the respirator or its cartridges/canisters are not approved (e.g., carbon monoxide exposure), or
(d)    When airborne concentrations may result in exposures that exceed the respirator’s protection factor.
(6)    The AAIS-PAs shall ensure adequate quantities of filtering facepiece respirators and other respirator components are available.

b.    Medical Evaluation.

(1)    Prior to training, fit testing, and use of respiratory protection, all employees must be medically evaluated and found qualified to wear the respirator selected for their use.
(2)    Each field office manager will identify his or her employees who will likely wear respirators and send the list to the AAIS-PM.
(3)    The AAIS-PM via a PLHCP will provide a medical questionnaire to all potential respirator users that will likely be administered online.
(4)    The online questions included on the questionnaire are compliant with the questions in the OSHA respiratory protection regulation.
(5)    The office shall not fit test or issue a respirator to an employee that has not been medically evaluated and determined by a PLHCP to be capable of wearing the designated respirator(s).
(6)    The PLHCP reviews each questionnaire. Followup consultations with a nurse or physician may be required to further determine if the employee is medically capable of wearing the respirator.
(7)    The AAIS-PM will provide the PLHCP with the list of all of the authorized respirators to be used, models, hazards requiring respirator use, and any other pertinent factors.
(8)    After evaluation, the PLHCP shall provide the employee and the AAIS-PM with a copy of the medical determination regarding the ability of the employee to wear a respirator.
(9)    If the PLHCP cannot make a positive determination based on the medical questionnaire, he or she may require or recommend further medical examination to determine the employee’s ability to wear a respirator.
(10)    Medical evaluations shall be in effect for 3 years unless otherwise determined by the PLHCP.
(11)    The AAIS-PM will collaborate with AAIS-PAs to track when employees are due for medical evaluations on the 3-year cycle. Examples of when additional medical evaluations could be provided include the following circumstances:
(a)    The employee reports signs and/or symptoms to the supervisor related to his or her ability to use a respirator, such as shortness of breath, dizziness, chest pains, or wheezing, or when he or she has a medical change such as an asthma diagnosis or a heart attack.
(b)    The medical provider or employee supervisor informs a program administrator that the employee needs to be reevaluated.
(c)    Information from the program, including observations made during fit testing and program evaluation, indicates a need for reevaluation.
(d)    A change occurs in workplace conditions that may result in an increased physiological burden on the employee.
(e)    The employee will start using a new respirator that was not included in his or her original respirator profile.
(12)    All examinations and questionnaires will be included in the employee’s occupational medical file via the FAA Occupational Medical Surveillance (OccMed) Program.

c.    Fit Testing.

(1)    AFS will utilize a combination of contract services, local medical professionals, and trained AFS employees to perform the required respirator fit testing. The AAIS-PM and the Regional OSH Program POCs will provide guidance on the best method for obtaining fit testing.
(2)    Fit testing is required for tight-fitting respirators (e.g., half-face APRs) and filtering facepiece respirators (e.g., P100).
(3)    Fit testing shall be conducted using the make, model, and size of respirator that the respirator user will wear. A minimum of two respirator models of each type will be made available for employees, plus a variety of sizes to afford an optimal fit.
(4)    Each employee shall be shown the proper method of donning, positioning, and strapping/tensioning the respirator to afford an optimal fit.
(5)     Fit testing shall be conducted annually for all mandatory respirator users and when changes occur that could impact adequate fit, such as weight change, scarring, cosmetic surgery, and use of dentures. Fit testing shall not be conducted until medical evaluation is complete and the medical opinion confirms the user’s capability to wear a respirator.
(6)    Employees will not be fit tested or issued respirators with tight-fitting facepieces if the person has conditions that could compromise the facepiece to face seal. Examples include facial hair, facial deformities, and jewelry or other objects that protrude under the facepiece seal.
(7)    For employees that cannot be fit tested and cannot use tight-fitting facepieces, the hooded PAPR may be an alternative for use, if approved by the AAIS-PM.
(8)    Whoever performs the fit testing shall document the fit test by employee, date, and all respirator types that the employee is approved to wear. The fit test documentation will be maintained in the employee’s medical file.
(9)    Prior to each use and if applicable to the type of respirator, the respirator user shall conduct a seal check as recommended by the manufacturer.

d.    Voluntary Use. AFS does not allow the voluntary use of respirators. AFS employees who are conducting work other than accident investigation must coordinate with the safety personnel for the worksite (to include host employers at external worksites where AFS employees conduct aviation safety inspections) to ensure work areas are at or below the OSHA Permissible Exposure Limits prior to entering an area where respirable hazards may be present.

e.    Cleaning, Maintenance, Storage, Change, and Disposal.

(1)    Filtering facepiece respirators (e.g., N95s and P100s) are disposable. For biohazards, the filtering facepiece respirators shall be disposed of after each use. For other agents (e.g., nuisance or toxic dusts), N95s and other filtering facepiece respirators shall be disposed of after each work shift, when the user detects that air flow is impaired, or when they become visually loaded with dust, whichever comes first. If a filtering facepiece respirator is expected to have biohazard contamination, it should be disposed of with the other biohazard items.
(2)    For tight-fitting APRs, each field office must establish a process for respirator cleaning, maintenance, storage, change, and disposal, with responsibilities delineated for the AAIS-PA and respirator users. This process should include adequate supply of parts, cartridges, etc.

f.    Respiratory Protection Training. This will be included in the AAIS training curriculum.

Appendix A. AAIS Program Definitions

1.    Air-Purifying Respirator (APR). A respirator with an air-purifying filter, cartridge, or canister that removes specific air contaminants by passing ambient air through the air‑purifying element.

2.    Assigned Protection Factor (APF). The workplace level of respiratory protection that a respirator or class of respirators is expected to provide to employees when the employer implements a continuing, effective respiratory protection program as specified by this section.

3.    Emergency Response Guidebook (ERG). A North American hazardous materials (hazmat) emergency response guide, published jointly by the United States, Canada, and Mexico Departments of Transportation (DOT) at 4-year intervals. Contains hazmat lists by name and by United Nations Identification Number, as well as numbered guides for emergency response, including fire and health hazards, initial public safety measures, firefighting procedures, initial isolation and protective action distances, personal protective equipment (PPE), and first aid. Refer to the Pipeline Hazardous Material Safety Administration (PHMSA) Web site: http://www.phmsa.dot.gov.

4.    Fit Test. The use of a protocol to qualitatively or quantitatively evaluate the fit of a respirator on an individual. (See also qualitative fit test (QLFT) and quantitative fit test (QNFT).)

a.    Qualitative Fit Test (QLFT). A pass/fail fit test to assess the adequacy of respirator fit that relies on the individual’s response to the test agent.

b.    Quantitative Fit Test (QNFT). An assessment of the adequacy of respirator fit by numerically measuring the amount of leakage into the respirator.

5.    Go-Kit. A portable bag with the expected safety equipment and PPE an aviation safety inspector (ASI) would need to conduct an aircraft accident investigation safely.

6.    Immediately Dangerous to Life or Health (IDLH). An atmosphere that poses an immediate threat to life, would cause irreversible adverse health effects, or would impair an individual’s ability to escape from a dangerous atmosphere.

7.    N95 Filtering Facepiece. A negative pressure particulate respirator with a filter as an integral part of the facepiece or with the entire facepiece composed of the filtering medium.
