Halon Halon 1211 has been widely used in portable fire extinguishers. Halon 1301 has seen widespread use in fixed systems throughout the industrial, commercial, marine, defence, and aviation industries. Halon 2402 has primarily been used in the defence, industrial, marine and aviation sector in some countries.

Halons are ozone depleting substances whose production and consumption is controlled under the Montreal Protocol. With support from the Protocol's Multilateral Fund delivered by UNEP, UNDP, UNIDO, the World Bank and bilateral agencies, developing countries are phasing out these ozone depleting chemicals in this sector.

The strategy for the halon sector essentially consists of two approaches: replacing halons with alternatives, and halon banking. Alternatives to halons include halocarbon alternatives, inert gases, water mist, fine particulate aerosols and streaming agents. In some cases, fire protection strategies may be re-considered and the need for halons eliminated. Halon banking, which includes recovery, recycling and establishing inventories, is used by companies and countries for managing existing halon supplies to cover remaining critical uses.

Looking for help with Halon?

Need help?UNEP helps developing countries to comply with their halon-related commitments under the Montreal Protocol. We provide National Ozone Units (NOUs) and other stakeholders, e.g. halon using industries, with the following assistance:

  • Information clearinghouse services, including videos, publications, newsletters, e-news
  • Training and capacity building activities
  • Direct assistance for specific technical, policy and data reporting needs related to halon

This assistance is provided through the Halon Phase-out Officer in UNEP's Compliance Assistance Programme (CAP). Regional Network Coordinators and Information Clearinghouse staff also provide support.

If you are an Ozone Officer or other stakeholder and you need help with halon management, please contact the CAP Regional Network Coordinator in your region or the staff of the other Multilateral Fund Implementing Agencies (see contacts at right).
