Air Quality Sampling Inspection Checklist [FREE PDF]

Air quality sampling inspections are essential for identifying and controlling workplace airborne hazards including chemical vapors, dust, and biological contaminants. OSHA 29 CFR 1910.134 mandates atmospheric monitoring when respirator use is required, while NIOSH RELs and ACGIH TLVs establish permissible exposure thresholds. Consistent air sampling documentation supports regulatory compliance, protects worker health, and provides defensible records under OSHA 29 CFR 1910.1020.

Industry: Industrial Hygiene

Compliance: OSHA 29 CFR 1910.134 Respiratory Protection, OSHA 29 CFR 1910.1020 Access to Employee Exposure and Medical Records, NIOSH REL Pocket Guide to Chemical Hazards, ACGIH TLV-TWA and TLV-STEL Threshold Limit Values, OSHA 29 CFR 1910.1000 Air Contaminants PEL Table Z-1

Pre-Sampling Preparation

Verify equipment calibration, sampling media, and documentation readiness before beginning air quality sampling.

Has all sampling equipment been calibrated within the manufacturer-recommended interval?
Is the correct sampling media (sorbent tube, filter cassette, impinger) selected for the target contaminant?
Have pre-sampling pump flow rates been measured and recorded in L/min?
Has a chain-of-custody form been prepared for laboratory submission?
Have the target contaminants and applicable OSHA PELs or NIOSH RELs been identified and documented?

Sampling Area Assessment

Evaluate work area conditions, worker activities, and potential contaminant sources before placing samplers.

Have all potential airborne contaminant sources in the sampling zone been identified?
Is the ventilation system operating under normal production conditions during sampling?
Have temperature and relative humidity been recorded for the sampling area?
What is the current ambient temperature in the sampling area?
Has the number of employees in the breathing zone area been documented?
Is photography or video documentation of the sampling setup being collected?

Personal Air Sampling

Conduct and document personal breathing zone air sampling for the most highly exposed workers.

Has the personal sampler been placed within the worker's breathing zone (10-inch radius of nose/mouth)?
Has the sampling start time been recorded?
What is the total sampling duration in minutes?
Did the worker perform representative tasks throughout the entire sampling period?
Were any process upsets, spills, or non-routine operations observed during sampling?

Area / Grab Sampling

Conduct area and grab air sampling to characterize overall workplace air quality and identify hot spots.

Have area samplers been placed at representative locations throughout the work zone?
Has a field blank sample been collected and labeled for each sampling type?
Have real-time direct-reading instrument readings been recorded as a screening complement?
What is the direct-reading instrument peak reading observed during sampling?
Have sampler locations been mapped or photographed for the sampling report?

Respiratory Protection Evaluation

Assess adequacy of current respiratory protective equipment relative to measured or anticipated exposure levels.

Is a written respiratory protection program in place per OSHA 29 CFR 1910.134?
Are workers currently using respirators appropriate for the identified contaminants and concentration range?
Have all respirator users received medical clearance per OSHA 29 CFR 1910.134(e)?
Have annual fit tests been documented for all tight-fitting respirator users?
Are spare respirators and replacement cartridges readily accessible in the work area?

Sample Handling & Laboratory Submission

Verify proper post-sampling handling, preservation, and submission of collected air samples to an accredited laboratory.

Have post-sampling pump flow rates been measured and recorded?
Have all sample media been sealed, labeled, and protected from contamination and light?
Is the laboratory receiving the samples AIHA-accredited or equivalent?
Has the chain-of-custody been signed by the sampler and is it ready for submission with samples?
Have turnaround time requirements been specified on the lab submission form?

Results Review & Corrective Actions

Document laboratory results, compare to regulatory limits, and initiate corrective actions where exposures exceed action levels.

Have laboratory results been compared against OSHA PELs (29 CFR 1910.1000), NIOSH RELs, and ACGIH TLVs?
Do any measured exposures exceed 50% of the OSHA PEL action level?
Have affected employees been notified of their individual exposure results within 15 working days?
Have engineering or administrative controls been identified or implemented to reduce exposures exceeding action levels?
Have exposure monitoring records been filed in the employee's exposure record for the required 30-year retention period?
Please provide any additional observations, corrective action notes, or follow-up sampling recommendations.
