Aircraft fuelers and into-plane service agents spend the majority of their shift directly beneath and adjacent to commercial aircraft during active gate operations — working around running APUs, ground power equipment, and the noise of adjacent aircraft taxiing and departing. Fueling operations keep workers at the aircraft for extended periods during each turn, producing some of the longest individual gate-level noise exposures of any ramp role. The CDC estimates 22 million U.S. workers face hazardous occupational noise each year, and aircraft fuelers are a meaningful segment of that total.
Soundtrace provides automated audiometric testing, real-time noise monitoring, and HPD fit testing in a unified platform for employers across the industries where aircraft fuelers work.
Aircraft fuelers are exposed to sustained high-level noise from aircraft APUs, ground power units, and adjacent aircraft operations throughout the gate fueling process. OSHA 1910.95 applies to fueling contractors and airline ground service operations under general industry jurisdiction. APU noise at fueling distances of 20–40 feet routinely measures 88–100 dBA — meeting or exceeding the action level for the full fueling duration.
Measured Noise Exposure Levels
| Operation | Typical Noise Level | OSHA Max Duration |
|---|---|---|
| Aircraft APU (20–40 ft, fueling position) | 90–102 dBA | Full fueling duration |
| Narrow-body engine start (nearby) | 100–115 dBA | Minutes |
| Ground power unit (GPU, adjacent) | 88–98 dBA | Full fueling duration |
| Fuel truck / hydrant cart (diesel) | 84–92 dBA | Full shift |
| Wing fuel panel (static discharge/hiss) | 80–86 dBA | Fueling duration |
| Adjacent aircraft taxiing | 95–108 dBA | During taxi |
| Ramp ambient (active operations) | 88–96 dBA | Full shift |
OSHA Requirements
Under 29 CFR 1910.95, employers must implement a hearing conservation program when any worker's 8-hour TWA meets or exceeds 85 dBA. Required elements:
- Noise monitoring to establish documented TWA for each exposed worker
- Baseline audiogram within 6 months of first qualifying exposure (preceded by 14 hours of quiet)
- Annual audiograms compared to baseline for standard threshold shift (STS) detection
- Hearing protection provided at no cost in a variety of types and styles
- Annual training covering noise hazards, HPD use, and audiometric results
- Recordkeeping per 1910.95(m) — noise measurements, audiograms, training documentation

Extended Gate Exposure Distinguishes Fuelers from Other Ramp Roles
Compared to baggage handlers who load and move between the aircraft and bag room, fuelers remain stationary at or under the wing for the full fueling duration — typically 15–45 minutes per wide-body turn. This stationary, extended proximity to APU and ground support noise creates higher per-turn cochlear dose than more mobile ramp roles.
Fuelers who complete 6–8 aircraft turns per shift, spending 20–40 minutes beneath each aircraft's APU at 90–100 dBA, accumulate 8-hour TWAs that consistently meet or exceed OSHA's action level. The extended stationary exposure makes personal dosimetry and HPD fit testing particularly important for fueling operations.

Workers' Compensation Exposure
Occupational hearing loss WC claims are routinely filed years or decades after the causative exposure. Without a documented baseline audiogram, employers cannot establish what hearing the worker had at hire — making every dB of loss present at claim filing presumptively attributable to the current employer.
A complete audiometric record, maintained from day one of employment, is the only document that allows an employer to separate their noise exposure period from everything that came before and after.

Frequently Asked Questions
Yes, when their 8-hour TWA meets or exceeds 85 dBA. Many aircraft fuelers in active operations regularly meet or exceed this threshold. OSHA 1910.95 requires employers to enroll qualifying workers in a hearing conservation program including audiometric testing, hearing protection, training, and recordkeeping.
Noise-induced hearing loss (NIHL) is the primary occupational hearing condition. It typically presents first as a 4,000 Hz notch on audiometry before progressing to involve 3,000 and 6,000 Hz. The loss is permanent and irreversible once established, which is why early detection through annual audiometry is critical.
Yes. Occupational hearing loss is compensable in all U.S. states when a worker can establish that their hearing loss was caused or contributed to by workplace noise exposure. Claims are routinely filed years or decades after the exposure period. Employers with complete audiometric records and documented noise measurements are far better positioned to contest causation or support apportionment.
A compliant hearing conservation program includes noise monitoring to document TWA, baseline and annual audiograms, hearing protection at no cost, annual training, and complete recordkeeping. Individual HPD fit testing — measuring each worker's personal attenuation rating (PAR) — is the only method that verifies actual protection rather than assuming label NRR performance.
Hearing protection must provide adequate attenuation for the actual measured TWA. Individual fit testing verifies each worker's personal attenuation rating (PAR). At higher exposure levels — above 100 dBA — double protection combining earplug and earmuff is often required to achieve adequate attenuation.
