The Military Manual (2005) of the Netherlands states:
0449. Recording
All information concerning mines, booby-traps and other devices should be logged. The locations should be given in the form of grid references. For the purposes of detection and clearance, maps, diagrams or other information should contain full information on the type, number, methods of placement, type of detonation device, lifetime, date and time of laying, tamper-proof devices (if fitted) and other relevant information. Copies of these written compilations should also be kept at a higher level of command. The parties to an armed conflict must keep the information on mines until after the end of the armed conflict.
0450. The logging obligation also applies to remotely delivered mines. For these mines, this means providing grid references for the estimated location and area of distribution. The area should, if possible, be marked at the first available opportunity. the number and type of mines laid, the date and time of laying and the self-destruction mechanisms should also be logged. In addition, a suitable warning should be given, before shooting or firing remotely delivered mines which might also affect the civilian population, unless circumstances do not permit.
0451. International marking
Minefields and mined areas must be marked with red or orange boards, with a yellow, reflective edge. The boards can be triangular or rectangular … The boards must be erected around the minefield or mined area, at intervals visible from each point to civilians approaching the area.
