International Course on Exposure Assessment of Hazardous Chemicals

International Workshop:
Advanced Course on Exposure Assessment of Hazardous Chemicals

in the Work Environment

Practical Tools for HSE Professionals

In short we want to present a few very practical tools in a 2-day training.

Day 1
– Introduction – Risk assessment of chemicals in the workplace (basic principles)
– “Expert system EASE”: computer program that allows assessment of the concentration of chemicals in the work environment, with easily obtainable input data (note: tool is developed by HSE in the United Kingdom)

Day 2
– “IHSTAT” – excel worksheet that enables statistical analyses of occupational hygiene measurement data and compliance testing (with occupational exposure limits). This tools is developed by AIHA (American Industrial Hygiene Association)
– “COSHH Essentials” – is a very practical tool that is available on the internet. This tool enables HSE professionals to select adequate control measures for chemical exposure reduction in the workplace. This tool is also developed by the Health and Safety Executive in the United kingdom.

Its is a true workshop during which the participants will spend about 50% of the training on practical exercises.  Participants are invited to bring exposure data / measurement reports to the training.

– To get familiar with the Expert system EASE (day 1) we will ask the participants to estimate the concentration of hazardous chemicals in the workplace and compare the estimates with their own measurement results.
– Exposure data will be used for very practical statistical analyses with the Excel-worksheet IHSTAT.
– The COSHH Essentials-tool will be used to select appropriate control measures for the workplaces, where participants have conducted exposure measurements.

Each participant will receive hand-outs of the presentations and practical exercises.  The software (Expert system EASE and IHSTAT)  and relevant reports/publications and background information will be delivered on CD/DVD by IndusTox.
