Z12885-12 - Nanotechnologies — Exposure control program for engineered nanomaterials in occupational settings
Nanotechnology is a multidisciplinary grouping of materials, applications and concepts, as well as physical, chemical, biological, engineering, and electronic processes. The defining characteristic is size: nanotechnology involves developing and using materials typically in the range of 1 to 100 nanometers (one nanometer is one billionth of a meter).
Expected to impact virtually every facet of global industry and society, the potential application of nanomaterials seems to be limitless. Unique properties exhibited at the nanoscale are being applied in a range of product areas that includes computers, health care, packaging, textiles, and energy. The use of engineered nanomaterials, however, as primary and intermediate components in manufactured products may raise worker and workplace safety concerns.
The first edition of CSA Z12885 contains valuable knowledge on occupational safety and health practices related to nanotechnologies. The first in a series of standards being adopted in Canada relating to the use of nanotechnologies in new processes, products and systems, CSA Z12885 is an adoption, with Canadian deviations, of ISO Technical Report 12885 - Nanotechnologies — Health and safety practices in occupational settings relevant to nanotechnologies.
CSA Z12885 is aligned with the Plan-Do-Check-Act (PDCA) continuous improvement model as found in occupational health and safety management systems (OHSMS) such as CAN/CSA-Z1000 Standard, Occupational Health and Safety Management.
Highlights of Z12885 include:
(a) Clearly outlines of responsibilities and accountability of senior management as well as encouraging worker participation
(b) Describes elements of hazard identification and risk assessment processes
(c) Reviews preventative and protective measures
(d) Outlines proper work procedures and sufficient training needs
(e) Includes comprehensive tables, graphs and illustrations
This is the first edition of CSA C393, Test methods for measuring power consumption in low and idle power modes of commercial and industrial equipment.
This Standard specifies methods for measuring electrical power consumption of equipment intended for use in commercial and industrial application when in low power mode(s) (i.e., standby mode, off mode, and network mode) and idle mode.
This Standard is applicable to electrical products with a rated input voltage or voltage range that lies wholly or partly in the range 100 V a.c. to 347 V a.c. for single phase input and 130 V a.c. to 7200 V a.c. for other inputs.
(1) The measurement of energy consumption and performance of products during intended use are generally specified in the relevant product standards and are not covered by this Standard.
(2) Where this Standard is referenced by performance standards or procedures, these should define and name the relevant low power modes (see Clause 3) to which this Standard is applied.
(3) The inclusion of d.c. powered products within the scope of this Standard is under consideration.
This Standard does not specify safety requirements. It does not specify minimum performance requirements nor does it set maximum limits on power or energy consumption.
The methods described in this Standard are not intended to be used to measure power consumption of products during in-service mode, as these are generally covered by other product standards (see Bibliography for some examples), although the measuring techniques, measurement uncertainty determination, and test equipment specifications may be adapted for such measurements with careful review.
In CSA standards, 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 (nonmandatory) to define their application.p>The strength and stability of portable ladders has direct workplace safety implications. The fourth edition of CSA Z11 - Portable ladders - includes design and performance-related requirements and tests for common types of portable ladders and accessories that are intended for one-person use (with the exception of trestle ladders).
