A clean hangar floor is a working tool
Hangar cleaning covers the aircraft bay floor, the back shops and parts rooms, the crew rooms, locker rooms and restrooms, and the offices and training rooms that sit along the hangar wall. Continental Facilities cleans all of it under one plan for maintenance, facility and EHS managers at hangars and aerospace maintenance buildings, and the hangar operator decides where crews go, when, and with which products.
The floor matters most. Military hangar design criteria favor a light gray floor finish because it contrasts with small parts and foreign objects and makes them easier to spot, and they call for a finish that is easy to clean for the same reason. The same criteria note that sand and grit left on the floor act as an abrasive and dull many finishes. Regular sweeping and scrubbing protect both the finish and a technician’s chance of seeing a dropped washer.
What crews clean in a hangar
Every area has a separate task list and time window, set at the walkthrough.
| Area | Typical work | When it usually happens |
|---|---|---|
| Aircraft bay floor | Dust-mop and sweep open floor, machine-scrub with products the operator approves, keep safety lanes and stop lines visible, bag debris for the operator’s FOD containers | When the bay is empty or in the zones the shop lead clears |
| Back shops and parts rooms | Floors, trash, sinks and the surfaces the shop lead releases; tools, parts and hardware stay where the technicians left them | Between shifts or overnight |
| Crew rooms, locker rooms and restrooms | Cleaning, disinfecting touchpoints and restocking paper and soap | Each service day, with refreshes between shifts |
| Offices, training rooms and lobby | Regular janitorial service, glass and floors | Evenings or weekends |
| Beams, lights and high structure | High dusting from lifts, top down, before the floor is scrubbed | On a periodic cycle, with aircraft moved or protected as the operator directs |
| Entries, walkways and lots | Sweeping, litter pickup and parking lot sweeping outside the airfield fence | On the exterior schedule |
Offices and crew areas run on our janitorial services, overhead work on high dusting, and floor scrubbing on floor care, so one service manager answers for every part of the building.
Finding and handling foreign object debris
The FAA describes foreign object debris (FOD) as anything out of place around an airport that might injure someone or harm an aircraft. Its FOD advisory circular (AC 150/5210-24A, February 2024) is guidance rather than a regulation, and each airport operator applies it under its own certification manual, but it gives a useful picture of what hangar cleaning should catch.
The circular describes clean-as-you-go as cleaning your surroundings before, during and after a shift, and it asks maintenance teams to account for nuts, bolts, washers, safety wire and hand tools. That shapes how crews work. Hardware or a tool found on the floor goes straight to the shop lead instead of the trash, so the shop can close out its own count. Paper, cardboard and plastic go into covered containers, because the circular notes that trash from hangar ramps can blow back onto areas aircraft use. Where the operator keeps FOD containers in the hangar, crews empty them on its schedule.
Floor finishes, spills and water
Hangar floors range from sealed or polished concrete to dry-shake hardeners and three- or five-coat epoxy systems, according to the military criteria, and the finish has to stand up to jet fuel and hydraulic fluids. Bare concrete is porous and takes up spills. Crews scrub each floor with the pads, products and dilution the coating maker and the operator allow, and they note worn or stained areas for the facility team.
Fuel and fluid spills belong to the operator’s spill plan. Research summarized by the NFPA’s Fire Protection Research Foundation found that 92% of fuel spills inside hangars happened during maintenance work, so crews report any spill to the shop lead at once and keep clear until the operator’s people have dealt with it.
Water use is planned with care. The EPA lists washwater among the pollutant sources at air transportation facilities, says washwater is not covered by an industrial stormwater permit, and recommends against sending it to a storm drain. California’s Industrial General Permit prohibits non-storm water discharges it does not authorize, and washwater is not on its authorized list. Crews favor dry methods and measured solution, never pour liquids into floor or trench drains, keep sweepings out of drain grates, and use the disposal point the operator names. Where the operator wants entries or walkways washed, our pressure washing crews plan their water use and protect nearby storm drains first.
Fire protection systems stay hands-off
NFPA 409, the Standard on Aircraft Hangars, covers hangar construction and fire protection, including foam systems, sprinklers and drainage floors. Inspection, testing and maintenance of those systems belong to the hangar owner and its fire protection contractor.
Crews keep clear of foam generators, nozzles, monitors, detectors, pull stations and manual releases, and never touch, test, reset, cover or block any of them. Carts, ladders and lifts are parked away from release stations. That matters: in surveys the Research Foundation summarized for 2004 to 2021, 357 of 432 hangar foam discharges were accidental, and its list of causes includes human error. When the owner schedules a system test, crews follow the test-day notice and stay out of the bay until the owner gives the word.
Lift work under the rafters
Dust and debris collect on trusses, light fixtures and door tracks high above the aircraft. Our crews dust them from lifts, working top down so falling dust lands on a floor that has not been scrubbed yet.
Federal rules frame how that work is set up. OSHA’s rule for vehicle-mounted aerial devices (29 CFR 1910.67) requires lift controls to be tested each day before use, allows only trained persons to operate the lift, and requires a personal fall protection system, a harness or travel restraint, attached to the boom or basket and never to the building or nearby equipment. Under 29 CFR 1910.28, where people below could be struck by falling objects, the employer uses measures such as a barricaded area kept clear of workers. California’s Title 8 section 3648 adds that only authorized persons may run aerial devices. High work in the bay is booked with the aircraft moved or protected and the floor below closed off, as the operator directs.
Ramps and hangars on an airport
A hangar on an airport usually opens onto ramp space that is part of the airport’s air operations area (AOA). The airport’s own security program defines that area, and the airport operator decides who may enter it, what identification they need and when an escort is required. Crews work on the ramp side only as that program allows, and the cleaning plan names which areas fall inside and outside the airfield fence. Our airport cleaning page explains how those rules work for terminals and other airport buildings.
Scheduling around aircraft movements
The hangar calendar drives the cleaning calendar. Bay floors are scrubbed when aircraft are out, during a planned gap between maintenance visits, or zone by zone where the shop lead clears space. Shops, crew rooms and restrooms are cleaned between shifts or overnight, and a day porter can keep restrooms, break rooms and trash under control while technicians work. High dusting runs on a slower cycle, often planned with a floor scrub the same night.
Hangars with large parts rooms, stores or attached warehouse space can fold that work into the same plan; our industrial and warehouse cleaning and manufacturing facility cleaning pages cover those floors in more detail.

A walkthrough with your maintenance or facility manager comes first: we look at the bay floor and its finish, the shops, the crew areas, the high structure and the operator’s rules for access, products and water. You then get a written quote that lists each area, its frequency and its time window. Continental carries insurance and a bond, covers its crews under workers’ compensation, and provides a certificate of insurance before work starts. Request a hangar walkthrough and we will schedule it around your aircraft.
A few useful answers
Common questions
Can the hangar floor be scrubbed with aircraft in the bay?
Open floor can be scrubbed in the zones the shop lead clears, kept well away from the aircraft. A full-floor scrub is booked for a night or weekend when the bay is empty.
What do your crews do with bolts or tools found on the floor?
They hand them to the shop lead instead of throwing them out, so the shop can account for its own hardware and tools.
Do your crews go near the foam system or sprinklers?
Crews keep clear of every foam and sprinkler component, detectors and release stations included, and never touch, test or block them. The hangar owner’s fire protection contractor handles that equipment.
Where does cleaning water go in a hangar?
Wherever the operator’s disposal point is. Crews favor dry methods, never pour liquids into floor or trench drains, and protect storm drains before any outdoor washing.
Can offices, crew rooms and shops be on the same plan as the bay?
Yes. One written plan and one service manager cover the bay floor, shops, crew rooms, restrooms, offices and high dusting, each on its own schedule.
