The poster demonstrates safe disposal of sputum by people with TB. Each of the two images on the top shows a man spitting, one into a bottle and the other one in a handkerchief. Between them is a large boiling pot. Underneath is a third image showing a woman spitting on a piece of paper, preparing to throw it into the fire. Text below specifies that bottles and handkerchiefs must be boiled for 20 minutes.
