Weapons clearance under extreme conditions

HI from Chad

Clearing explosive remnants of war with Pitchou Lusamba, HI Demining Team Supervisor.

5:30 AM: The weapons clearance platform is a SAG200, made especially for HI and its operations in Chad. It is a kind of large combine harvester with rotating front arms that detonate all explosive devices in its path. It is transported to the site by truck from its garage in the center of Faya-Largeau. After unloading and some adjustments, it goes into action.

Charles Coly, a weapons clearance expert, who has been trained to use the platform, remotely controls it at a safe distance: "For safety reasons, I always need to be more than 150 meters from the machine when it is on contaminated land. The front arms rotate at nearly 3,000 rpm. They dig 20 centimeters into the ground and destroy all explosive devices in their path. Normally, the mines are automatically torn to pieces; they don't even have time to explode. But sometimes they do. A few weeks ago, a rocket exploded as the machine passed over it. The machine was unharmed: it is designed to withstand an explosion."

6:30 AM: The weather and lack of wind have reduced visibility and made it hard to use the platform correctly. Supervisor Pitchou decides to stop it and sends out the manual weapons clearance experts instead.

7:00 AM: Six weapons clearance experts equip themselves with demining aprons, helmets and metal detectors. They walk along the 200-meter access corridor to the clearance site. They work in teams of two. The first demines and the second watches from a safe distance, ready to help if there’s a problem.

7:30 AM: Manual work is long and meticulous. The weapons clearance experts work along a meter-wide corridor. They pass the metal detector over the ground and advance in 40cm steps. A ruler on the ground marks each step forward. "It doesn't look like it, but it's an exhausting job. It's 40 degrees, we're in full sunlight wearing all the equipment. Deminers need regular breaks. They must be fully focused on the job. Their movements need to be precise and they must follow the mine clearance instructions at all times," says Pitchou.

8:00 AM: The temperature reaches 40 degrees. The weapons clearance experts work in 45-minute shifts. At ten o’clock, they take a break for something to drink and eat. They work like this until noon, when the teams return to base. In the meantime, the machine is taken back to the garage where it is given routine checks.

These mine clearance operations restore the use of tracks and land to local people, who can grow crops and rear livestock again. This opens up the Faya-Largeau region, which has been slow to develop due largely to explosive remnants of war.

In addition, since last January, HI and its partner Mobility Robotics have been trialing the use of drones to support weapons clearance experts in Faya-Largeau, northern Chad.
