REACH and OSH legislations are aiming at the same goal: safety, health and wellbeing of a worker handling chemical substances at work. Terminology and the overall language used within these legislative frameworks differ from each other. At an average European workplace the personnel handling REACH issues or CAD issues may be different. Registrant and a downstream user may have difficulties in communication. In addition to the practical issues causing discrepancies, in a broader perspective, also more profound differences in the philosophy of the two sets of legislation can be pointed out. This has to be understood in order to guarantee proper implementation. A good example of this is setting the European OELs vs. DNELs.... [-]
