Statistics from

Given the high estimated prevalence and financial burden of occupational asthma (OA),1 ,2 prevention is a major concern. However, in the absence of a regulatory screening protocol, the respiratory sensitising potential of a chemical is usually only apparent when it has caused a human case of OA.

The purpose of primary prevention is to detect hazardous agents before the occurrence of the issue, in order to avoid exposure of workers.3

Agius et al4 have developed and validated a computer based asthma hazard prediction model to predict the potential of low molecular weight (LMW) organic agents to cause asthma …
