A big office building in Larnaca has a problem. People had to leave the building quickly. They left because the air inside was not good. The bad air made one woman feel sick.
People who know about chemicals are looking at the problem. They think the bad air came from cleaning products. Someone used the wrong products together. This can make a dangerous gas.
This gas is not good for people to breathe. It can make it hard to breathe and can make you sick.
Now, the building is closed. People cannot go back inside. They must wait until the air is clean and safe again. This is the third time something like this has happened in Cyprus.
