Definition of Household Hazardous Waste
This is the first edition of CSA Z752, Definition of Household Hazardous Waste. This Standard has been developed to assist regulators and manufacturers in defining household wastes that present significant risks to human health or the environment.
This Standard provides the foundation for a comprehensive and proactive approach to managing HHW. This criteria-based definition primarily describes to manufacturers what is and is not included in the definition of HHW. This Standard also allows for the development of a system for identifying those household products that are HHW on disposal. The development of a consistent message to consumers and clear disposal instructions, in turn, is expected to motivate consumers to reduce the generation of HHW and motivate manufacturers to change formulating and packaging decisions in order to reduce the generation of HHW. The desired result is positive behavioural changes, on the part of manufacturers and consumers, that reduce risk and result in improved human and environmental health, and improvements to the effectiveness and efficiency of current HHW programs.
The criteria in this Standard have been developed based on an assessment of risks and on a review of relevant legislation, regulations, standards, and codes.
The support of the Canadian Consumer Specialty Products Association, Canadian Household Battery Association, Association of Municipal Recycling Coordinators, Recycling Council of Alberta, and North American Hazardous Materials Management Association in the development of this Standard is gratefully acknowledged.
This Standard defines those household wastes that present significant risks to humans or the environment when disposed of in one or more systems within the regular domestic waste stream.
This Standard can be used to
(a) guide product development;
(b) develop communication programs to inform the public about which materials are HHW and how to dispose of them properly;
(c) assist in the development and encouragement of product stewardship programs; and
(d) guide the collection and disposal of HHW. This Standard is based on commonly accepted practices, codes, standards, and regulations used in Canada.
This Standard is not wholly applicable in some cases where a waste management system fails to comply with minimum requirements of applicable standards or regulations. This Standard does not
(a) provide disposal recommendations or specific labelling requirements regarding the categories of wastes it describes;
(b) provide guidance on the packaging, use, or storage of domestic products within the household;
(c) address waste management systems that are outside of the regular domestic waste stream (e.g., industry product stewardship programs, special household waste collection programs);
(d) cover occupational hazards associated with the management of materials in HHW programs;
(e) specifically address the unauthorized or illegal disposal of materials (e.g., materials disposed of in municipal storm sewers); and
(f) cover substances that are used in occupational contexts.
