A UK scheme to help small firms control health risks from chemicals: toxicological considerations

摘要

The UK has developed a simple scheme to provide practical control advice and medium- sized enterprises(SMEs), to assist them in their risk assessments and risk management decisions. This scheme makes use of toxicological hazard information indicated by R-phrases assigned under The European Union(EU)classifications system, to assign substances to hazard bands. In the UK Scheme, the allocation of substances to hazard bands according to R-phrases has taken into Account three key factors: whether or not the toxicological endpoint has an identifiable dose Threshold; the seriousness of the resultant health effect; and the relative exposure levels at which Toxic effects occur.
