If necessary, you can also indicate the expected exposure for each substance. By doing this, the system can calculate an exposure ratio and give an indication of the exposure risk. To do this, indicate the expected exposure on the exposure screen. Next you choose with which parameter you want to compare this exposure. You can only choose between MAC TWA 8 hours or MAC STEL 15 minutes. Possible conversion of PPM to mg/m³ will be done by the system for you.

The data entered is kept in the exposure records. Also when the limit value of the substance may change in the future.
