What are pictograms? Also called hazard symbols or pictograms, they are like drawings that alert us to the presence of a dangerous (or hazardous) chemical that we can find in a laboratory. They help us to know that the chemical we are using may cause harm to people or the environment. But in our daily life we can also have and use products that have these pictograms. It is important to know what they mean to avoid danger. Our 2º ESO students show some of them to us.
