1 Domaine d'application Le présent Rapport technique décrit un processus pour identifier, évaluer, traiter, prendre des décisions sur les risques potentiels du développement et sur l'utilisation de nanomatériaux manufacturés et de les communiquer afin de protéger la santé et la sécurité du public, des consommateurs, des travailleurs et l'environnement. Bien que le processus de gestion de produit et de gestion des risques décrit dans le présent Rapport technique ne soit pas unique pour les nanomatériaux, il complète des approches reconnues en mettant l'accent sur, le cas échéant, des informations et des aspects spécifiques aux nanotechnologies. Il présente des directives relatives aux informations nécessaires pour effectuer des évaluations des risques et prendre des décisions relatives à la gestion des risques adaptées, ainsi que la conduite à suivre en cas d'informations incomplètes ou incertaines en utilisant des hypothèses raisonnables et des pratiques de gestion des risques appropriées. De plus, il comprend des méthodes pour mettre à jour des hypothèses, des décisions et des pratiques au fur et à mesure que de nouvelles informations deviennent disponibles, et sur la façon de communiquer des informations et des décisions aux parties prenantes. Le présent Rapport technique suggère des méthodes que les organisations peuvent utiliser pour être transparentes et responsables en ce qui concerne la gestion des nanomatériaux. À cette fin, il existe un processus pour organiser, documenter et communiquer les informations dont disposent les organisations sur les nanomatériaux. Cela comprend la détection d'informations incomplètes, la description du traitement des brèches d'information et l'explication de la justification des décisions et actions de gestion des risques des organisations.
Nanotechnologies — Assessment of risks associated with nanomaterials
Nanotechnologies - Nanomaterial risk evaluation (First edition)
1 Scope This Technical Report describes a process for identifying, evaluating, addressing, making decisions about, and communicating the potential risks of developing and using manufactured nanomaterials, in order to protect the health and safety of the public, consumers, workers and the environment. While the overall product stewardship and risk management process set forth in this Technical Report is not unique to nanomaterials, it supplements recognized approaches by providing, where possible, a focus on information and issues specific to nanotechnologies. It offers guidance on the information needed to make sound risk evaluations and risk management decisions, as well as how to manage in the face of incomplete or uncertain information by using reasonable assumptions and appropriate risk management practices. Further, it includes methods to update assumptions, decisions, and practices as new information becomes available, and on how to communicate information and decisions to stakeholders. This Technical Report suggests methods organizations can use to be transparent and accountable in how they manage nanomaterials. To that end, it describes a process of organizing, documenting, and communicating what information organizations have about nanomaterials. This includes acknowledging where information is incomplete, explaining how information gaps were addressed, and explaining the rationale behind the organization's risk management decisions and actions.
