Stoffenmanager Nano tool available to aid preliminary hazard classification of nanomaterials
Created by assoceditor on 04/08/2011 15:41:34

The Stoffenmanager Nano 1.0 tool aids users to rank potential health risks due to occupational inhalation exposure to nanomaterials.

Despite rapid growth in the manufacturing and use of nanomaterials, concerns have been raised about their potential adverse effects resulting from the current lack of knowledge regarding their health risk assessment. Stoffenmanager Nano 1.0 - launched earlier this year as a new module of the generic Stoffenmanager 4.0 and now available in English - offers employers up to date information to assess the risks of working with nanomaterials.

Stoffenmanager Nano 1.0, freely available online, is an instrument to rank potential occupational health risks due to inhalation exposure to manufactured nano-objects (MNO), and to implement effective control measures. This tool therefore facilitates compliance with the precautionary principle, advised by the Social and Economic Council of the Netherlands (SER) for working with nanomaterials.

In order to use Stoffenmanager Nano 1.0, users need a limited amount of product-specific information, which is probably listed in the Material Safety Data Sheet (MSDS) in combination with the product’s Technical Data Sheet. With these details, and a good idea of the relevant worker activities with nanoparticles, users can perform a preliminary assessment of the potential hazards of the material.

Stoffenmanager Nano applies to MNO that meet all of the following criteria:

Particles are not (water) soluble, and;
The particles are purposely (synthetically) produced and not released as unintentional by-product, such as the particle production as a result of incomplete combustion processes, and;
The size of the primary particle is smaller than 100 nm and / or the specific surface area of a nanopowder is larger than 60 m2/g;
It concerns single particles as well as agglomerates or aggregates.

It should be noted that Stoffenmanager Nano is, at this stage, a 'work-in-process' online tool that reflects the current knowledge on risks related to working with nanomaterials. It will be further adjusted when new insights become available.
