Monitoring exposure

Abstract

Abstract Monitoring of exposure level enables organisations to evaluate the level of risks to hazards in occupational setting. Majority of hazards are assigned occupational exposure limits (OELs) and monitoring of exposure may be required to demonstrate compliance with specific legislation. This chapter highlights the different sample types that can be collected as well factors which should be considered when selecting appropriate sampling and analysis methods. The chapter also discusses how to design exposure surveys (sampling strategy) to ensure that the relevant data is collected to address the objectives of workplace surveys. The chapter also explains how collected exposure data should be interpreted with a few worked examples. As well as measurement of airborne pollutants the chapter also includes section on methods for evaluating dermal exposure which is important for substances which can absorbed through skin or known to cause contact dermatitis.
