Asbestos is a mineral that workers used in buildings because it was strong and it didn’t burn.

Later, specialists found out that if people breathe these pieces, they can have lung diseases. These small fibers can stay in the air and get into the lungs, which can cause problems many years later.

Many countries don’t allow the use of asbestos anymore, but some old houses and factories still have it. Workers who repair or destroy these buildings must be very careful. They should wear protective clothing and follow safety rules.

In some countries, people still use asbestos because it is cheap. Health experts say asbestos is very dangerous and workers must remove it safely. If people think their house has asbestos, they should call professionals instead of touching it themselves.
