Lecture 01: Introduction to Air Sampling

This foundational lecture introduces the scope, structure, and regulatory basis of the training. Participants are expected to have a background in general chemistry and occupational hygiene. The course is built on OSHA and NIOSH standards and spans 16 academic hours. It emphasizes the importance of monitoring airborne contaminants to protect worker health and outlines the main routes of exposure: ingestion, skin absorption, and inhalation. The lecture also introduces the concept of Occupational Exposure Limits (OELs), how to identify hazardous substances using Safety Data Sheets (SDS), and the basic equipment needed to start an air sampling business.

Lecture 02: Chemicals in Air and Their Regulated Limits

This module dives into the regulatory landscape of airborne chemicals. It explains the different types of exposure limits—TWA, STEL, Ceiling—and how they apply to various scenarios. The lecture highlights the complexity of interpreting these limits, especially when dealing with unregulated substances. It discusses how to guide clients using scientific literature, analogs, and internal policies. The concept of OELs as statistical compromises between public health and economic feasibility is explored, along with examples like lead and formaldehyde. Participants learn to critically assess exposure scenarios and navigate gaps in regulation.

Lecture 03: Air Sampling Principles

Here, the focus shifts to the mechanics and ethics of sampling. Participants learn the distinctions between personal and area sampling, the importance of representative sampling, and how to handle confined spaces. The lecture emphasizes ethical considerations when working with employees and the need for clear communication. It also introduces direct reading instruments and their limitations, including spot measurements and grab samples. The session concludes with practical examples and guidance on how many samples to collect based on project scope.

Lecture 04: Sampling of Dust and Mist

This lecture covers particulate sampling, including non-volatile solids and liquids. It explains how different particle sizes—PM10, PM2.5, respirable, thoracic—affect health and sampling strategy. Participants learn about size-selective sampling tools like cyclones, impactors, and IOM samplers. The importance of selecting the correct filter media (PVC, MCE, PTFE, Quartz) is discussed in detail. Practical troubleshooting advice is provided, including how to avoid sample overload and ensure sufficient air volume. Real-world examples, such as sampling in a cement warehouse, help contextualize the theory.

Lecture 05: Sampling of Vapours and Gases

This module explores techniques for capturing volatile and semi-volatile compounds. It covers absorption in liquids, adsorbent tubes, derivatization, and passive sampling. Participants learn the strengths and limitations of each method, including flow rate considerations and breakthrough phenomena. The lecture also introduces emergency tools like colorimetric tubes and discusses how to sample for complex mixtures like SVOCs. A case study involving a refinery illustrates how to plan large-scale sampling for multiple compounds.

Lecture 06: Scans and Multiple Tests

This session introduces advanced analytical strategies like chemical scans (BTEX, PAH, metals) and open characterization. It explains how to interpret semi-quantitative results and manage the risks of over-reporting. Participants learn how to coordinate multiple tests on a single sample and use indicators for indirect sampling. The concept of “worst-case scenario” sampling is introduced as a practical solution when ideal conditions are unavailable. The lecture emphasizes critical thinking and communication with clients and labs.

Lecture 07: Pumps, Calibration, and Size-Selective Sampling

Participants learn the technical aspects of sampling equipment, including pump types, calibration methods, and flow indicators. The lecture explains how to calibrate pumps before and after sampling and maintain quality control logs. It also covers the selection of appropriate calibrators (mass flow, dry, wet, rotameter, bubble) and how to troubleshoot calibration errors. The importance of using pressure-compensated pumps and understanding flow dynamics is emphasized. A quiz reinforces the calculations involved in determining air volume and flow rates.

Lecture 08: Pre-Sampling Study

This module focuses on client communication and project planning. It guides participants through the process of understanding the client’s needs, identifying potential conflicts, and selecting target chemicals. A scenario involving catalyst unloading is used to illustrate how to assess risks, select regulated compounds, and prepare a sampling plan. The lecture emphasizes the importance of documenting communications, understanding production chemistry, and anticipating hidden hazards like PAHs.

Lecture 09: Planning Field Work

Participants learn how to design a compliant and effective sampling strategy. The lecture covers screening tests, method selection, and how to avoid unnecessary results. It emphasizes the importance of confirming lab capabilities and estimating sampling duration, air volume, and flow rate. Practical advice is given on preparing quotes, renting equipment, and assembling a field toolkit. The session concludes with cost estimation exercises for both premium and economical service options.

Lecture 10: Field Work Execution

This hands-on module prepares participants for real-world sampling. It covers timing, equipment setup, worker interaction, and uninterrupted sampling. The importance of record keeping and traceability is stressed, along with monitoring sampling conditions and troubleshooting common issues. Participants learn how to handle long shifts, collect multiple samples, and use direct reading instruments. Ethical challenges and misconduct are addressed with sensitivity and professionalism.

Lecture 11: Quality Control and Assurance

This lecture reinforces the importance of QA/QC in air sampling. It explains the role of blank samples, calibration logs, and field notes in ensuring data integrity. Participants learn how to interpret multiple tests, identify faulty equipment, and recover lost information. The session emphasizes transparency, documentation, and continuous improvement. Real-world examples illustrate how to detect inconsistencies and maintain credibility.

Lecture 12: Communication with Laboratories

Participants learn how to collaborate effectively with analytical labs. The lecture covers sample handling, interferences, accreditation, and turnaround times. It explains how to select appropriate methods, manage logistics, and troubleshoot spoiled or lost samples. The importance of reviewing lab reports, understanding error margins, and interpreting results is emphasized. Participants are encouraged to build strong relationships with labs and maintain clear communication throughout the project.

Lecture 13: Reporting Results

This module teaches participants how to compile and present their findings. It covers report structure, data calculations, and adjustments for TWA, STEL, and Ceiling values. The lecture explains how to compare results with legal standards and best practices, and how to interpret exposure to multiple chemicals. Participants learn to identify action levels, defend their conclusions, and communicate results with clarity and confidence.

Lecture 14: Miscellaneous Topics

This session addresses important but often overlooked aspects of air sampling. It discusses the pros and cons of in-house testing, the use of preliminary results, and the selection of direct reading instruments. Liability, errors, and client communication are explored in depth. Participants are encouraged to maintain rigorous QA programs and develop internal review systems to catch mistakes before they reach the client.

Lecture 15: Final Summary and Future Directions

The final lecture reviews the entire training program and offers guidance for continued professional development. Participants are encouraged to study national and international regulations, read manufacturer manuals, and pursue further training. The lecture highlights business opportunities in consulting, laboratory setup, and international collaboration. Certificates are issued, and participants are welcomed into a global network of industrial hygiene professionals.

🎓 Certification
