Responses to the European Center for Risk Management and Safe Innovation in Nanomaterials and Nanotechnologies (EC4SafeNano) survey on demand and supply of services in nanosafety are due September 15, 2017. EC4SafeNano notes that multiple responses from different departments and groups within a single organization are possible. As reported in our April 24, 2017, blog item, EC4SafeNano wishes to develop a catalog of services matching the anticipated needs and service requirements to the supply of services from different organizations. It has sent a survey to different stakeholders, including European Union (EU) Member States, the European Commission (EC) and EC agencies, industry, and bodies representing the general public. Responses will influence the design of EC4SafeNano and ensure that issues important to stakeholders will be addressed; the catalog of services will be relevant; and services can be provided through EC4SafeNano. EC4SafeNano will be developed over the next three years to bridge the gap between scientific knowledge and daily practice by providing services to help others to manage this new technology safely. EC4SafeNano will anonymize and summarize the survey responses in a report that will be made available to all respondents.
