Exposure Modelling

Predict Worker Exposure using a Chemical Exposure Calculator

The vast majority of worker exposures are never sampled. And who can blame them when you consider the cost of sampling? Most exposures are not assessed because of a lack of a convenient and reliable way to estimate exposure. Most workplaces don’t have the training to perform a credible worker assessment and simply don’t know where to start.

WATSIN is an exposure calculator that was developed to estimate worker exposure. Answer 6 questions and the exposure is predicted as falling into a range of exposures relative to the Occupational Exposure Level (OEL). WATSIN has the following applications:

1 ) As a screen to eliminate unnecessary air sampling

2 ) Predict exposure of a new chemical that is coming into your plant

3 ) To explore possible substitution with safer chemicals
