Practice Relating to Rule 82. Recording of the Placement of Landmines
Chad’s Law on Anti-Personnel Mines (2006) states:
As far as possible, the relevant sections of the Ministry responsible for national defence attend to the establishment of an inventory of areas in which anti-personnel mines are known or suspected to have been emplaced. 
Chad, Law on Anti-Personnel Mines, 2006, Article 13.
The Law also states:
If an area has been identified in which anti-personnel mines are known or suspected to be emplaced, the relevant sections of the Ministry responsible for the national defence and security must ensure that to the extent possible, this area is perimeter-marked according to the international rules on the fight against mines, [and that it is] monitored and protected by fencing or other means in order to prevent civilians from entering until all anti-personnel mines in this area have been destroyed.
This marking must at least be to the standards set out in the Protocol on Prohibitions or Restrictions on the Use of Mines, Booby-Traps and Other Devices, as amended on 3 May 1996, annexed to the Convention on Prohibitions or Restrictions on the Use of Certain Conventional Weapons Which May be Deemed to Be Excessively Injurious or to Have Indiscriminate Effects.
