A mine clearance agency is a group of specially trained people who work to make areas safe from dangerous explosives called landmines. These landmines are like secret bombs that are hidden in the ground and can explode when someone steps on them. They were often put there during wars, and they can hurt and kill people even after the fighting has stopped.
To clear these dangerous landmines from an area, the people from the mine clearance agency have to search very carefully and use special tools to find and remove them. They have to be very careful and follow special rules to protect themselves while they work. They may use metal detectors, sniffer dogs, or even robots to help them find the landmines.
Once they find a landmine, they use special equipment to safely remove it. This equipment might include long poles or robots with arms that can dig around the landmine and carefully remove it without setting it off. Then, they can safely dispose of the landmine so it won't cause harm to anyone in the future.
It can be a dangerous job, but the people who work for mine clearance agencies are very brave and dedicated to helping to ensure that areas are safe for people to live and work in.
