1 Scope
1.1
This Standard specifies requirements for establishing and maintaining an exposure control program for
engineered nanomaterials in the workplace in accordance with occupational health and safety
management system (OHSMS) principles (see CAN/CSA-Z1000 and Clause 4 of this Standard).
1.2
This Standard provides guidance on health and safety practices in occupational settings relevant to
nanotechnologies (see Annexes A to E).
1.3
The information in this Standard reflects current information about nanotechnologies, including
characterization, health effects, exposure assessments, and control practices. The terms and definitions
used in this Standard are consistent with those developed under ISO TC 229, the ISO Technical
Committee on nanotechnologies.
1.4
This Standard focuses on the manufacture and use of engineered nanomaterials in workplaces. It does
not address health and safety issues or practices associated with nanomaterials generated by natural
processes, hot processes, and other standard operations that unintentionally generate nanomaterials or
potential consumer exposures or uses, though some of the information in this Standard could be
relevant to those areas. The information in this Standard can help companies, researchers, workers, and
others to prevent adverse health and safety consequences during the production, handling, use, and
disposal of engineered nanomaterials. This advice is broadly applicable across a range of nanomaterials
and applications. For the purposes of this Standard, the term “nanomaterials” refers to engineered
nanomaterials.
1.5
In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to
satisfy in order to comply with the Standard; “should” is used to express a recommendation or that
which is advised but not required; and “may” is used to express an option or that which is permissible
within the limits of the Standard.
Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a
note accompanying a clause is to separate from the text explanatory or informative material.
Notes to tables and figures are considered part of the table or figure and may be written as
requirements.
Annexes are designated normative (mandatory) or informative (non-mandatory) to define their
application.
