Air Quality Sampling Inspection Checklist [FREE PDF]

Workplace air quality sampling is governed by OSHA 29 CFR 1910.134 and NIOSH Recommended Exposure Limits (RELs), requiring employers to assess airborne contaminants and implement engineering controls when thresholds are exceeded. Industrial hygienists must follow ACGIH Threshold Limit Values (TLVs) as benchmarks for chemical, biological, and physical agents present in the work environment. Accurate sampling, documentation, and employee notification are critical components of a legally defensible

  • Industry: Industrial Hygiene
  • Frequency: Quarterly
  • Estimated Time: 45-60 minutes
  • Role: Industrial Hygienist
  • Total Items: 35
  • Compliance: OSHA 29 CFR 1910.134 Respiratory Protection, OSHA 29 CFR 1910.1020 Access to Employee Exposure and Medical Records, NIOSH RELs (Recommended Exposure Limits) - NIOSH Pocket Guide to Chemical Hazards, ACGIH TLVs and BEIs - Threshold Limit Values for Chemical Substances, OSHA 29 CFR 1910.1000 Air Contaminants (Table Z-1, Z-2, Z-3)

Pre-Sampling Preparation

Verify equipment calibration, documentation readiness, and hazard identification prior to sampling activities.

  • Has the sampling plan been reviewed and approved by a certified industrial hygienist prior to this event?
  • Have all direct-reading instruments been calibrated within the manufacturer's recommended interval?
  • Have chemical hazards, process activities, and potential contaminants been identified using the SDS library?
  • Is the selected sampling method consistent with NIOSH Analytical Method or OSHA Method for the target contaminant?
  • Has a field blank sample been prepared for each sample media type used in this event?

Sampling Equipment Setup

Confirm proper assembly, flow rate verification, and personal sampling pump functionality before deployment.

  • Is the personal sampling pump flow rate verified pre- and post-sampling using a primary calibrator?
  • Is the sampling media (sorbent tube, filter cassette, impinger) appropriate for the target contaminant?
  • Is the sample pump positioned within the breathing zone (6–9 inches from mouth/nose) for personal sampling?
  • Are sample collection start time, pump ID, and employee name documented on the chain of custody form?
  • Is direct-reading instrument data being logged continuously or at specified intervals for real-time monitoring?

Area and Work Conditions Assessment

Document environmental conditions and process activities that may affect contaminant generation and dispersion.

  • Are temperature and relative humidity recorded at the sampling location?
  • Are all ventilation systems (local exhaust, general dilution) operating normally during the sampling period?
  • Is the production rate or process activity level representative of a typical work shift?
  • Are any respiratory protection devices (APF) worn by sampled employees during the sampling period?
  • Are photographs of the sampling setup and work area conditions captured for documentation purposes?

Sample Collection and Duration

Verify that sampling duration and volume meet minimum requirements for accurate quantification of target contaminants.

  • Is the full-shift sampling duration at least 7 hours to represent an 8-hour TWA per OSHA requirements?
  • Is the total air volume sampled sufficient for the laboratory's Limit of Quantification (LOQ) for each contaminant?
  • Have sampling interruptions (breaks, pump stoppage) been documented with start/stop times?
  • Is sorbent breakthrough checked for tube samples by analyzing the backup section separately?
  • Have sampled employees been informed of the sampling activity and purpose in accordance with OSHA requirements?

Sample Handling and Chain of Custody

Ensure proper capping, labeling, storage, and shipping of samples to maintain integrity and legal defensibility.

  • Are all sample tubes/cassettes immediately capped and sealed with end caps after removal from pump?
  • Are samples stored at the temperature specified by the analytical method prior to shipping?
  • Is each sample uniquely labeled with sample ID, date, time, contaminant, and sampled employee ID?
  • Has the chain of custody form been completed and signed by the inspector and will accompany samples to the lab?
  • Is the laboratory accredited by AIHA-LAP LLC or an equivalent accreditation body for the contaminants being analyzed?

Results Review and Exposure Comparison

Compare analytical results to regulatory limits and occupational exposure limits and determine action levels.

  • Are measured TWA concentrations below the OSHA Permissible Exposure Limit (PEL) for each contaminant?
  • Are measured concentrations below the ACGIH TLV-TWA for each substance?
  • Are any results above the OSHA Action Level (AL) triggering mandatory medical surveillance or respiratory protection?
  • Have results been communicated to affected employees in writing within 15 working days of receipt?
  • Are corrective action recommendations documented if any results exceed action levels or OELs?

Recordkeeping and Record Retention

Verify proper documentation, storage duration, and employee access rights for all exposure monitoring records.

  • Are exposure monitoring records retained for at least 30 years per OSHA 1910.1020 requirements?
  • Are records stored in a format accessible to employees, their designated representatives, and OSHA upon request?
  • Does the sampling report include all required data: dates, methods, instruments, results, and CIH reviewer signature?
  • Have sampling records been entered into the occupational health management system or exposure database?
  • Additional notes or observations from sampling event?
