Maximizing the Efficacy of Exposure Assessment Methodologies (AIHce EXP 2019 OnDemand)

Course Description:
Recorded at AIHce EXP 2019

How Do We Get More Effective Exposure Control From Our Exposure Assessments?
You assessed your workers' exposures and put in expensive controls. You re-monitored, the results are in and you are going to tell them their exposures are now higher? What? How'd that happen? In this session we will examine the disconnect that can occur between exposure assessments and exposure controls that can lead to poor outcomes.

Protective Action Level Strategies When Exposure Data Are Limited
Health and safety programs seeking to proactively manage chemical exposures to acceptable levels might choose to apply an action level as a layer of protection beyond an occupational exposure limit (OEL). Exceedance of an action level is intended to trigger various actions, ranging from investigative measures such as repeat exposure monitoring or medical monitoring, to more intensive strategies such as engineering controls. This presentation will analyze the various strategies available to establish and apply action levels in a dynamic workplace, and will focus on those strategies that can be used when limited exposure data are available for a given similar exposure group (SEG). Strengths and weaknesses of the different strategies, in addition to an overview of their performance in terms of accurately judging exposure profiles, will be discussed.

Nothing Detected – Nothing Gained?
Pharmaceutical substances and other chemicals used in industry have become increasingly potent.Increasingly lower Occupational Exposure Limit recommendations are being developed. At the same time, industrial hygienists are increasingly interested in collecting task-based data in scenarios where exposure duration may be far less than eight hours. This presents both an analytical and statistical challenge. This presentation discusses case studies where this challenge was overcome through analytical method improvements and by choosing the right method to analyze data below the Limit of Quantitation (LOQ).
