Audit Setup and Inspector Information

Audit date and time

Record the exact date and time this audit is being conducted.

Inspector name and employee ID

Full name and employee ID of the person conducting this audit.

Nitrogen generator unit ID / location

Enter the equipment asset tag number and physical location (e.g., Bay 3, Service Lane A).

Previous audit deficiencies resolved?

Confirm all deficiencies noted in the prior daily audit have been corrected or are actively tracked in the corrective action log.

Yes No N/A

Nitrogen Generator Purity and Output

Nitrogen purity reading (%) critical (required)

Record the purity percentage displayed on the generator's purity analyzer or inline sensor. Minimum acceptable value is 95%. Values below 95% are a critical non-conformance — remove unit from service immediately.

Purity analyzer / sensor functioning and displaying a live reading critical (required)

Confirm the purity display is active, not showing an error code, and has been calibrated within the manufacturer-specified interval.

Yes No N/A

Generator output pressure (psi)

Record the output pressure shown on the generator gauge. Acceptable range is typically 100–150 psi; verify against your unit's nameplate rating.

Generator power indicator / status light shows normal operation

Confirm the unit is powered on, no fault or alarm LEDs are illuminated, and the unit is in ready/standby or active state.

Yes No N/A

Compressed Air Supply and Filtration

Inlet compressed air pressure within generator's specified feed range (psi)

Record the inlet air pressure. Most PSA/membrane generators require 90–120 psi feed air. Consult unit nameplate for exact specification.

Pre-filter element — no visible moisture, oil, or discoloration in sight glass critical (required)

Inspect the coalescing pre-filter sight glass or drain bowl. Presence of liquid water or oil indicates filter saturation — replace element before continuing operation.

Yes No N/A

Auto-drain on pre-filter actuated and functioning (if equipped)

Manually trigger the auto-drain test button (if present) and confirm condensate is expelled. A non-functioning drain can saturate the filter and degrade purity.

Yes No N/A

Air dryer / desiccant status — no saturation indicator alarm

Check the desiccant dryer moisture indicator (if equipped). A pink or red indicator means the desiccant is saturated and must be regenerated or replaced.

Yes No N/A

Hoses, Fittings, and Inflation Equipment

Inflation hose(s) — no cuts, abrasions, kinks, or bulging along full length critical (required)

Visually inspect each inflation hose from the generator outlet to the chuck end. Any cut exposing inner braid, bulge, or severe kink is a critical deficiency — remove hose from service.

Yes No N/A

Chuck / inflation valve — seats properly, no audible leak when connected to test port

Connect the chuck to a capped test valve stem and listen/feel for leakage. A leaking chuck results in inaccurate inflation and nitrogen waste.

Yes No N/A

Quick-connect fittings — no visible cracks, corrosion, or missing retaining clips critical (required)

Inspect all quick-connect couplings. Missing retaining clips can cause uncontrolled hose separation under pressure (OSHA 29 CFR 1910.169 whip hazard).

Yes No N/A

Inflation gauge accuracy verified against calibrated reference gauge (within ±2 psi)

Compare the inflation gauge reading against a calibrated reference gauge at a known pressure. Gauges out of tolerance by more than ±2 psi must be recalibrated or replaced.

Yes No N/A

Safety, Signage, and Work Area Compliance

"Nitrogen — Asphyxiation Hazard" warning sign posted at generator and inflation station critical (required)

OSHA 29 CFR 1910.145 requires hazard warning signs where oxygen-displacing gases are used. Confirm signage is legible, undamaged, and visible from the approach direction.

Yes No N/A

Area ventilation adequate — no enclosed space with restricted airflow around generator critical (required)

Nitrogen is an asphyxiant (OSHA 29 CFR 1910.146 permit-required confined space considerations). Confirm the generator is not operating in a sealed room without ventilation.

Yes No N/A

Work area clear of combustibles within 3 feet of generator and hose connections

Per NFPA 1, compressed gas equipment areas must be kept free of flammable/combustible materials. Inspect a 3-foot radius around the unit.

Yes No N/A

Emergency shutoff / isolation valve accessible and unobstructed critical (required)

Confirm the main nitrogen supply shutoff valve is clearly labeled, reachable within 10 seconds, and not blocked by equipment or materials.

Yes No N/A

Deficiencies, Corrective Actions, and Sign-Off

Total number of deficiencies identified during this audit

Enter the count of all non-conformances noted. Enter 0 if none.

Describe each deficiency and assigned corrective action (or enter 'None')

For each deficiency: state the item, describe the non-conformance, identify the responsible person, and set a target resolution date. Example: 'Pre-filter sight glass shows oil — filter element replaced by J. Smith, 2024-06-10.'

Unit status at end of audit critical (required)

Select the operational status of the nitrogen inflation system following this audit.

Inspector signature

By signing, the inspector certifies that all items above were physically verified and that all findings are accurately recorded.
