Purpose
This guidance addresses the event of a commercial passenger aircraft traveler exhibiting symptoms consistent with Ebola disease or another viral hemorrhagic fever (VHF, e.g., Marburg virus disease, Lassa fever, Rift Valley fever, Crimean-Congo hemorrhagic fever). The guidance only applies to travelers with identified exposures or laboratory-confirmed infection.
Overview
To date, there is no documented evidence of hemorrhagic fever viruses being transmitted on an aircraft1.
What aircraft this applies to: This guidance applies to commercial passenger aircraft located in the United States.
Who this is for: Airlines and contract companies whose staff may clean, disinfect, or remove contaminated waste from an aircraft.
How to use: Use these recommendations 1) to guide personnel in cleaning, disinfection, and waste disposal procedures after a flight, 2) to select effective disinfectants, and 3) as a reference for relevant federal regulations.
Disclaimer: This guidance does not relieve any person of the obligation to comply with all applicable Federal Aviation Administration (FAA) regulations for issues related to the aircraft and Occupational Safety and Health Administration (OSHA) regulations for those workers conducting the decontamination of the aircraft or handling and disposing waste.
Related Guidance:
- CDC's Preventing Spread of Disease on Commercial Aircraft: Guidance for Cabin Crew details general infection control precautions and management of a sick traveler in-flight. This guidance also provides guidance on cleaning, disinfection, and waste disposal procedures during flight.
- Per federal regulations, reporting death or illness is required for domestic flights between U.S. states and territories, and on international flights arriving in the United States. Reporting tools for airlines, cabin crew, and pilots are available in the Airline Guidance for Reporting Death/Illness.
Routine practices regardless of the presence of a sick traveler
Airlines should direct the airline personnel and/or designated cleaning crew to clean the passenger aircraft using airline-specified detergents and disinfectants and/or refer to the Guide to Hygiene and Sanitation in Aviation developed by the World Health Organization (WHO). As certain detergents or disinfectants may be incompatible with aircraft components, any detergent or disinfectant used on board an aircraft should be approved by the aircraft manufacturer.
Recommendations for cleaning and disinfection of the aircraft when a traveler exhibits symptoms consistent with a VHF
The approach for cleaning and disinfecting the aircraft depends on the symptoms of the ill traveler at the time they were on the passenger aircraft. The following are approaches for an ill traveler who was symptomatic during a flight and is suspected of having a VHF but does not yet have a laboratory-confirmed diagnosis.
- If the ill traveler had NO gastrointestinal (vomiting or diarrhea) or hemorrhagic (bleeding) symptoms while on the aircraft, the person should not have contaminated their environment. Routine cleaning and laundering can be conducted by airline personnel or designated cleaning crew/environmental services employees. These recommendations apply even if a VHF is confirmed by laboratory testing after the flight.
- If the ill traveler had gastrointestinal (vomiting or diarrhea) or hemorrhagic (bleeding) symptoms while on the aircraft, the aircraft should be taken out of service immediately. The aircraft can be held until the laboratory-confirmed diagnosis has been obtained. If a VHF is confirmed, follow the cleaning and disinfection process outlined below. The airline may also choose to assume the ill traveler is infected and proceed to the cleaning and disinfecting process outlined below without waiting for laboratory confirmation. If a VHF has been ruled out, the aircraft can be cleaned using conventional protocols.
Recommendations for cleaning and disinfection of the aircraft when a VHF is confirmed and traveler had gastrointestinal or hemorrhagic symptoms at the time they were on the aircraft
- Follow OSHA's Fact Sheet 3756 on Cleaning and Decontamination of Ebola on Surfaces – Guidance for Workers and Employers in Non-Healthcare/ Non-Laboratory Settings.
- Select and provide personal protective equipment (PPE) to protect cleaning workers from exposure to hemorrhagic fever viruses and to chemical hazards from the cleaning and disinfectant agents. Refer to the OSHA PPE Selection Matrix for assistance in determining the appropriate PPE. Employers must comply with OSHA's standards on Bloodborne Pathogens (29 CFR 1910.1030), PPE (29 CFR 1910.132), Respiratory Protection (29 CFR 1910.134), Hazard Communication (29 CFR 1910.1200), and other requirements, including those established by state plans, whenever such requirements apply.
- For non-porous surfaces (e.g., door handles, arm rests, tray tables) contaminated by the ill traveler, use a disinfectant included in the Environmental Protection Agency (EPA) List L: Disinfectants for Use Against the Ebola Virusor List Q: Disinfectants for Emerging Viral Pathogens (EVPs). Always use disinfectants according to manufacturer's instructions. As certain disinfectants may be incompatible with aircraft components, any disinfectant used on board an aircraft should be approved by the aircraft manufacturer.
- Contaminated porous materials (e.g., linens, carpet, pillows, seat cushion) and waste generated in the care of the ill traveler should be properly contained, packaged, and disposed of as a category A infectious substance according to State, EPA, and Department of Transportation (DOT) regulations, including DOT Hazardous Materials Regulations (HMR, 49 CFR, Parts 171-180). Store the properly contained contaminated material in a secure area or room that is not being used until it can be picked up by a company with a permit for transporting Category A infectious substances (DOT Special Permit 16279). Additional guidance for managing contaminated waste include DOT Safety Advisory: Packaging and Handling Ebola Virus Contaminated Infectious Waste for Transportation to Disposal Sites and Managing Solid Waste Contaminated with a Category A Infectious Substance published by a Federal interagency working group.
Additional considerations
- If a traveler is confirmed to have a VHF and had gastrointestinal or hemorrhagic symptoms at the time they were on the aircraft, the airline may choose to arrange for a contract company to decontaminate the aircraft and manage contaminated waste. If contracted support is required, companies that may have experience performing this kind of cleaning and decontamination include those certified through associations such as the National Institute of Decontamination Specialists (NIDS), Institute of Inspection, Cleaning and Restoration Certification (IIRC), or American Bio Recovery Association (ABRA), or who have completed training as outlined in the OSHA Hazardous Waste Operations and Emergency Response Standard (HAZWOPER). The contract company must comply with OSHA's standards on Bloodborne Pathogens (29 CFR 1910.1030), PPE (29 CFR 1910.132), Respiratory Protection (29 CFR 1910.134), Hazard Communication (29 CFR 1910.1200), and other requirements, including those established by state plans, whenever such requirements apply.
- Airlines personnel should routinely handle lavatory wastes using proper PPE and hygiene practices for all flights2. There has been no evidence to date that ebolaviruses or other hemorrhagic fever viruses can be transmitted via exposure to sewage3. However, there may be local requirements for pre-treating (adding disinfectant) this waste prior to discharge and airlines should check with the local wastewater treatment plant.
- The FAA has investigated vaporized hydrogen peroxide technology as a potential biocide; this may be considered as an option for disinfection of a passenger aircraft45678. Investigators have also been evaluating other potential fumigants that may be of use, including methyl bromide and methyl iodide9. The use of these fumigants may require a Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) Section 18 Exemption from the EPA.
