Course Overview

This practical and highly-interactive course includes various practical sessions and exercises. Theory learnt will be applied using our state-of-the-art simulators.

The aim of this course is to provide the participant with a sound understanding of the techniques for assessing exposure to hazardous substances in the workplace and with an understanding of how exposure information can be used to assess risk.

On completing this course successfully, the participants will be able to:

  • Describe the general approach to health risk assessment, including the role of atmospheric monitoring
  • Select appropriate equipment to measure specific airborne contaminants and devise a suitable sampling strategy
  • Presents the results in a form useful for health risk assessment purposes to enable management to comply with relevant legislation

The course is normally run as a 5-day taught course (minimum of 45 hours including lectures, tutorials, practical/demonstration sessions, guided reading, overnight questions and examinations). There will be a 40 short answer question “open book” examination with an allowed time of 120 minutes.

This course is designed to provide participants with a detailed and up-to-date overview of hazardous substances measurement. It covers the hazard and risk assessment process covering information gathering, assessing risk, actions, records and management; and the air sampling theory and practice including workplace sampling strategies, survey design, personal sampling, area sampling, surface and other measurements and confined spaces.

During this interactive course, participants will learn the air sampling equipment’s comprising of pumps, sampling heads and filters, direct reading instruments and calibration of air sampling equipment; the sample analysis including trace level analytical methods, gravimetric analysis, microscopy and quality assurance of analysis and the hygiene standards and biological monitoring as well as calculation, interpretation, presentation of results.

Learning Outcomes

Upon the successful completion of this course, each participant will be able to:

  • Achieve the OHTA-BOHS Certificate in W501: Measurement of Hazardous Substances
