In this episode host Mark Reggers and guest Debbie Dietrich, Senior Vice President and Corporate Industrial Hygienist for SKC Inc. continue where they left off and resume their discussion on the subject matter of Exposure Monitoring.

Exposure monitoring is a quantitative measurement of environmental hazards to which workers may be exposed to. It is a critical component of any Occupational Hygiene program in the prevention of illness and the preservation of health. Assessments help determine the types of controls required to remove or reduce a range of workplace hazards to things like chemicals, noise, radiation or heat stress to safe and acceptable levels.

In this episode, part 2 of 2, Mark & Debbie discuss the following:

• Can you explain how passive samplers work for exposure monitoring?
• Is there a limited number of chemicals passive samplers can be used for?
• How does a workplace know what laboratory to send their samples to?
• Can direct-reading instruments be used for exposure monitoring?
• Can you explain the difference between the worst-case sampling approach and the random sampling approach strategies?
• What are some common pitfalls associated with exposure sampling?
• Where can listeners get more information on exposure monitoring?
• How can listeners get in contact with yourself or SKC?

With the widespread use of chemicals in industry, exposure to hazardous substances can be found in many workplaces that are detrimental to worker health and safety. Exposure monitoring is required under OH & S laws where there is a significant risk to due to using, handling, generating or storing hazardous chemicals. There are legal limits to the concentration of some of the chemical fumes that workers may be exposed to. For this reason, we need to know how much of the chemical the worker is actually breathing in to ensure their exposure is minimised to safe levels. Tune in as we look at exposure monitoring; what it is and how it’s performed.
