1、Designation: E2996 15Standard Guide forWorkforce Education in Nanotechnology Health and Safety1This standard is issued under the fixed designation E2996; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A
2、number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This guide provides guidelines for basic workforceeducation in health and safety topics related to nanotechnology,to be taught at an un
3、dergraduate college level. This educationshould be broad to prepare an individual to work safely withinone of the many areas in nanotechnology research,development, or manufacturing. The individual so educatedmay be involved in material handling, manufacture,distribution, storage, use, or disposal o
4、f nanoscale materials.1.2 This guide may be used to develop or evaluate aneducation program for health and safety issues in the nano-technology field. This guide provides listings of key topics thatshould be covered in a nanotechnology education program onthis subject, but it does not provide specif
5、ic course material tobe used in such a program. This approach is taken in order toallow workforce education entities to ensure their programscover the required material while also enabling these institu-tions to tailor their programs to meet the needs of their localemployers.1.3 The values stated in
6、 SI units are to be regarded asstandard. No other units of measurement are included in thisstandard.1.4 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and heal
7、th practices and determine the applica-bility of regulatory limitations prior to use. The immediate andlong term hazards, if any, of many nanomaterials are unknown.This guide does not address concerns with consumer usage andeventual disposal of products that contain nanomaterials.1.5 This guide may

Terminology3.1 Definitions:3.1.1 For definitions of terms related to nanotechnology ingeneral, refer to Terminology E2456 and ISO/TS 27687.3.2 Definitions of Terms Specific to This Standard:3.2.1 nanomaterial, nmaterial with any external dimen-sion in the nanoscale or having
10、 internal structure or surfacestructure in the nanoscale.3.2.2 nanoscale, adjhaving one or more dimensions fromapproximately 1 to 100 nanometres (nm).3.2.3 nanomanufacturing, nfabrication of nanomaterial orthe incorporation of nanomaterials into other products.4. Significance and Use4.1 The purpose
11、of this guide is to provide a basic educa-tional structure in the health and safety aspects of nanotech-nology to organizations developing or carrying out educationprograms for the nanotechnology workforce. This guide helpsto describe the minimum knowledge base for anyone involvedin nanomanfacturing
12、 or nanomaterials research.4.2 The basic education should prepare an individual forvaried roles in the nanotechnology workplace. The material inthis guide may require a post-secondary two-year science ortechnology background to be understood sufficiently. Depth onthe topics should be sufficient to t

Thehazards, if any, presented by nanomaterials can be verydifferent from those presented by bulk/macroscopic materials.4.4 Because nanotechnology is a rapidly developing field,the indivi
17、dual educated in nanotechnology needs to be cogni-zant of changing and evolving safety procedures and practices.Individuals should be aware of how to keep current on thetechnology, and have a base education that enables synthesis ofemerging safety procedures and practices.5. Course Content5.1 The mi
18、nimum recommended course content for work-force education in nanotechnology health and safety shouldinclude education on known and potential health risks, safework practice in the nanotechnology workplace, nanotechnol-ogy and general laboratory safety, and understanding of SafetyData Sheets (SDSs).H
