Nanoparticle risk assessment using the "Banding" control method

The OHB (Occupational Hazard Band) method deals solely with health risks. It uses an MMR (risk management measure) criticality grid. The OHB method is a simplified semi-quantitative method based on the hazard statements of the CLP regulation ( règlement n° 1272/2008 du 16 décembre 2008 ).

The first step is to define a hazard level based on the information available on the substance.

So the first thing to do is to look for all the information you need, and first of all :

• the name of the substance, IUPAC name ;

• its identifiers: CAS n°, CE n° ;

• information on any impurities ;

• ...
