Carbon tetrachloride CAS number:
Date circular:

Chemical name: Methane, tetrachloro-

Final regulatory action has been taken for the category: Pesticide, Industrial

Final regulatory action: The chemical is Severely Restricted

Use or uses prohibited by the final regulatory action:

All uses and formulations prohibited.
1.The Regulations prohibit the manufacture, use, sale or offer for sale, import or export of bulk virgin carbon tetrachloride, except for certain allowed uses described below.
2.The Regulations prohibit the import of recovered, recycled, reclaimed or used carbon tetrachloride, except for certain allowed uses described below.
3.The Regulations prohibit the manufacture and import of products that contain or is intended to contain carbon tetrachloride, except for certain allowed uses described below.

Use or uses that remain allowed:

The manufacture, use, sale, offer for sale, and import of bulk virgin carbon tetrachloride are allowed for the following purposes:
essential uses which are to be identified at the international level on the basis of essential-use criteria adopted by the Parties. Canada considers these exemptions on a case-by-case basis;
analytical standard.
The import of recovered, recycled, reclaimed or used carbon tetrachloride is allowed for use as feedstock or for an essential purpose.
The manufacture and import of the following products containing carbon tetrachloride is allowed:
military ships before January 1, 2003
a pest control product before January 1 2000, provided that the product was registered under the Pest Control Products Act before January 1 1999.
aircraft, ships or any vehicle manufactured before January 1999
a product imported in a consignment of personal or household effects and intended for the importer's personal use only
a product that is an animal or human health care product, including any bronchial dilator, inhalable steroid, topical anaesthetic and veterinary powder wound spray:
a product that is supplied in a container of 3 litres or less and that is to be used for an essential use that is a laboratory or analytical use.
The use, sales, offer for sale of domestic (ie not imported) recovered, recycled, reclaimed or used carbon tetrachloride for any purpose.

Pesticide use or uses that remain allowed:


The final regulatory action was based on a risk or hazard evaluation: Yes

Summary of the final regulatory action:

In Canada, the federal and provincial governments are responsible for regulating various aspects of ozone depleting substances in the country. Federal and provincial regulatory programs are complementary, and form an integral part of Canada's Ozone Layer Protection Program. The federal government is generally responsible for implementing the provisions of the Montreal Protocol, including controls on the manufacture, import and export of ODSs under the Canadian Environmental Protection Act. Provincial governments are responsible for the regulation of emissions and discharges to the environment, and govern the implementation of ODS recovery and recycling programs, and emission controls under provincial regulations.
The Ozone-depleting Substances (ODS) Regulations prescribe conditions under which a person may manufacture, import, export, use, sale, or offer for sale in Canada all substances known to deplete the ozone layer. In addition, the Regulations prohibit the use or sale of controlled ODSs that would have been illegally imported or manufactured after the phase-out date. The Regulations also require that permits be obtained to import or export used, recovered, recycled and reclaimed ODSs, limited to certain allowed uses. They control the consumption of ODS, namely halocarbons such as CFCs, halons, HCFCs, methyl bromide, carbon tetrachloride and 1,1,1-trichloroethane. Companies are issued permits for the manufacture, import or export of the prescribed ODSs.
The Regulations also prohibit any person from manufacturing, importing, selling or offering for sale any product containing ODS, including pressurized containers containing less than 10 kg of a chlorofluorocarbon, packaging material for food that is made of plastic foam in which a chlorofluorocarbon is the foaming agent, and products such as mobile air-conditioning units, fire extinguishers and insulation boards that come from countries that are not signatories to the Montreal Protocol. The intent is to minimize or eliminate ODS emissions from non-essential uses.
The pesticide use of carbon tetrachloride has been suspended since February 1984.

The reasons for the final regulatory action were relevant to: Environment

Summary of known hazards and risks to the environment:

Substance with an ozone-depleting potential of 1.1. Stratospheric ozone depletion leads to an increase in the intensity of UV-B rays that reach the earth's surface, where they can disrupt important biological processes and affect air quality.

Expected effect of the final regulatory action in relation to the environment:

Canada's contribution to global ODS emissions is relatively small (about 2% of total) and so is its short term contribution to global benefits. More substantial benefits come from the combined effects of party countries implementing the reduction and phase-out schedules. Computer models predict that maximum ozone layer depletion will be encountered around the year 2000. The impacts of the measures taken will then be felt to their fullest extent after 2000; the rate of ozone depletion should then diminish. It is estimated that , as a result of the measures adopted by the parties to the Montreal Protocol, the ozone layer will fully recover by 2080

Date of entry into force of the final regulatory action: 01/01/1999
