Documents

 
This section provides information that may assist you in implementing your halon management plan. It includes specific technical information on halon substitutes, recovery, recycling and destruction, as well as regional industry case studies. Additional, more general information may be found here as well.

The UN Technology and Economic Assessment Panel (TEAP) includes a number of committees that conduct research and provide information about topics relevant to the manufacture, use, and destruction of substances that deplete the ozone layer.

The Halon Technical Options Committee (HTOC) has produced a number of reports that include useful information specifically on halons. The most recent and relevant documents to halon management are presented below. In each report, the sections that are particularly relevant are identified here for easy reference. The link will provide access to the entire text for each report.

These documents are only a fraction of the available reports on substances that deplete the ozone layer. The entire text of all TEAP documents can be downloaded from www.teap.org.

HALON SUBSTITUTES

Halon substitutes can be divided into two groups - 1) replacements and 2) alternatives. Replacements are compounds that are like halons, i.e., other, less ozone-depleting halocarbons. Alternatives are compounds or materials that are chemical dissimilar to halons, for example, carbon dioxide, water, dry chemicals, or inert gases.

CASE STUDIES

These are international and regional case studies of efforts made to reduce use of halons and other ozone-depleting substances. These case studies provide insight into the ways that other countries have managed their halon problem, and can be used as examples for other countries.
