LCS Laboratory Inc is pleased to announce a new 8-hour training course, Industrial Hygiene Air Sampling, available on request, online live or in person.
The course is designed for consultants and field technicians who are learning the principles of industrial hygiene air sampling. It is also valuable for professionals already working in air sampling. For experienced teams, the training builds confidence in the quality of their services and helps make survey results defendable, whether they are reviewed by a client, a regulator or a court.
Course description
The course follows the logic of a real sampling project, from the first question (“what did the worker breathe, and is it below the limit?”) to the final report.
Why we sample. We begin with the fundamentals: how exposure and dose relate to concentration, duration and breathing rate, and how chemicals affect people at different levels. You will learn how occupational exposure limits work (TWA, STEL and ceiling values), where to find legally enforceable limits and recommended guidelines, and why you must always use the limit that applies where the work is done. We also cover the main reasons clients request air testing: due diligence, workers’ concerns, government orders, pre-start reviews, and source and engineering testing.
Principles of sampling. Participants learn why samples must be representative: collected in the worker’s breathing zone, during typical work, over a typical shift. We explain the difference between active sampling, passive sampling and direct-reading instruments. We also explain why active, full-shift sampling with laboratory analysis remains the compliance standard.
Worked examples with calculations. Using realistic examples, you will calculate air volume, convert laboratory results into airborne concentrations, convert mg/m³ to ppm, and compare results with exposure limits. Examples cover dust and mist (including total dust, metals such as lead, and respirable crystalline silica) and solvent vapours (including toluene and TVOC). The course also covers how to interpret results and what to recommend when a worker is overexposed.
Equipment and technique. We review sampling pumps, filter cassettes, cyclones, adsorbent tubes, holders and complete sampling trains. You will learn how to choose media for different contaminants, how to avoid problems such as breakthrough, and how to care for your equipment.
Calibration, blanks and quality assurance. These are the foundation of defendable results. The course explains pump calibration, field blanks, chain of custody, sample handling and shipping, traceable records, and how to work effectively with an accredited laboratory. It also covers liability and the key contents of a professional industrial hygiene report.
Field project case study. The day ends with a complete project from start to finish: sampling for respirable crystalline silica at a stone countertop fabrication shop. Participants plan the survey, prepare the equipment, complete the calculations, interpret the results and discuss how to report them to the client. A class exercise and a review of the most common mistakes in the field reinforce the key points.
Flexible delivery
The training can be delivered online live or in person, and it is scheduled on request to suit your team.
