A simplified way to describes part of Occupational Hygiene, is through this scheme.

A contaminant (source) is being dispersed or transmitted to a receptor.  Many elements then comes into play.  What is the source?  What is the contaminant? What is the concentration? Can we eliminate/substitute the source? How is it being dispersed? Can we control/reduce/eliminate its dispersion? Who will be the receptor?  What will be its exposure? What is the frequency? What is the duration? What will be the impact on its health? On short term/long term? And many other questions…

We encourage people working in the field of OHS to expand their knowledge to understand and answer these questions.  Please do not hesitate to use our Network tool to ask questions.  The following links will provide you resources to find some answers and follow the evolution of knowledge in our field of practice.
