Dr. Rolf Packroff OSH testing and information requirements for biopersistent particles and fibres 8 th EU-US Joint Conference on Health and Safety at Work, Fort Worth, "Nanomaterial" means a natural, incidental or manufactured material containing particles, in an unbound state or as an aggregate or as an agglomerate and where, for 50 % or more of the particles in the number size distribution, one or more external dimensions is in the size range 1 nm nm. EU definition for nanomaterials (proposal of 2011)

Dr. Rolf Packroff OSH testing and information requirements for biopersistent particles and fibres 8 th EU-US Joint Conference on Health and Safety at Work, Fort Worth, is not helpful for a legal discrimination of known health risks from inhalation of bio-persistent particles or fibres (better use existing definitions for respirable particles and WHO fibres)... offers only a limited legal security for industry and authorities due to a lack of standardized methods and high costs for identification of nanomaterials For OSH the EU definition of nanomaterials... carcinogenic potency fibre diameter (µm) Pott, F - ASP 8/77

Dr. Rolf Packroff OSH testing and information requirements for biopersistent particles and fibres 8 th EU-US Joint Conference on Health and Safety at Work, Fort Worth, Guidance of the German CA for characterisation of nanomaterials (2012): A nanoscaled morphology generally does not modify a substance to another substance. The nanoscaled form has to be registered together with the bulk material, if their quantity from production or import exceeds 1 ton per year. Nanomaterials and REACH

Dr. Rolf Packroff OSH testing and information requirements for biopersistent particles and fibres 8 th EU-US Joint Conference on Health and Safety at Work, Fort Worth, REACH is lacking in information and testing requirements for coherent workers protection, which... … obliges producers and importers for an exposure and risk assessment of biopersistent substances, which have a relevant potential for release of respirable particles, despite not being classified as hazardous acc. to the CLP regulation, … generates useful information on dustiness of a material during relevant activities for downstream users, … decribes tests to determine bio-persistence of released particles for deduction of toxicological reference values (DNEL / DMEL) and to derive exposure scenarios for a safe use along the supply chain. … enables a targeted identification of materials, which release respirable and biopersistent fibres of high concern for human health.

Dr. Rolf Packroff OSH testing and information requirements for biopersistent particles and fibres 8 th EU-US Joint Conference on Health and Safety at Work, Fort Worth, Research vs. Regulation Health and Safety Research antenna function for new risks verification of hypotheses good expert manning development of new methods Regulation practicable enforceable risk-related coherent limited expert manning established methods Do we need a nano definition in OSH regulation? Do we need a nano definition in OSH regulation? Maynard's comment in Nature proposes that a "‘one size fits all' definition of nanomaterials will fail to capture what is important for addressing risk," and suggests that regulators use "a list of nine or ten attributes (including size and surface area) for which certain values trigger action“ Andrew D. Maynard, Nature, 475, 31 (2011)
