It still amazes me just how complex this project is.
We wrote the software for mixture sensitizer calculations twice. We had two completely different approaches. One was to adjust the classification itself depending on the different cutoffs in the regions the SDS was being displayed.
We got it working but didn't like adjusting the classification. Multiple classifications for the same mixture felt wrong. What would an injured worker think of software design which hid a hazard in one region but displayed it in another? It didn't feel right to simply say those regions classify things differently. Finally, it didn't fit with our aim to harmonize regulations themselves. We eventually felt the "best practice" from a non-chemist viewpoint would be to classify per the most rigorous cutoff and fully inform SDS users about the scenario with a disclaimer.
