PART III
CONFIDENCE-BUILDING MEASURES
1. Pursuant to Article IV, paragraph 68, each State Party shall, on a voluntary basis, provide the
Technical Secretariat with notification of any chemical explosion using 300 tonnes or greater of
TNT-equivalent blasting material detonated as a single explosion anywhere on its territory, or at
any place under its jurisdiction or control. If possible, such notification shall be provided in
advance. Such notification shall include details on location, time, quantity and type of explosive
used, as well as on the configuration and intended purpose of the blast.
2. Each State Party shall, on a voluntary basis, as soon as possible after the entry into force of this
Treaty provide to the Technical Secretariat, and at annual intervals thereafter update, information
related to its national use of all other chemical explosions greater than 300 tonnes
TNT-equivalent. In particular, the State Party shall seek to advise:
(a) The geographic locations of sites where the explosions originate;
(b) The nature of activities producing them and the general profile and frequency of such explosions;
(c) Any other relevant detail, if available;
and to assist the Technical Secretariat in clarifying the origins of any such event detected by the
International Monitoring System.
3. A State Party may, on a voluntary and mutually-acceptable basis, invite representatives of the
Technical Secretariat or of other States Parties to visit sites within its territory referred to in
paragraphs 1 and 2.
4. For the purpose of calibrating the International Monitoring System, States Parties may liaise with
the Technical Secretariat to carry out chemical calibration explosions or to provide relevant
information on chemical explosions planned for other purposes.
