When we want to make something new, like a toy or a snack or even medicine, we need to check if it is safe for us to use. Just like how we check if toys are safe before we play with them and snacks are safe before we eat them, scientists do a chemical safety assessment to check if the things we make are safe to use.
A chemical safety assessment is a way to make sure that the chemicals we use in making things like toys, snacks, and medicine are safe to use. It is like a safety check-up for the chemicals! Scientists who do the safety check-up look at the properties of the chemicals closely, like what they are made of, what they do, and how they might affect us if we use them.
They also look at how the chemicals might react with other things around them, like other chemicals or the environment they will be used in. For example, if we want to use a chemical in making medicine, we need to know if it will mix well with our body and not hurt us.
After looking at all these things, the scientists will decide whether the chemical is safe to use or not. If the chemical is not safe, they will look for ways to change it or use a different chemical instead.
In summary, a chemical safety assessment is a way for scientists to make sure that the chemicals we use in making things are safe to use. They check the properties of the chemicals and how they might react with other things to make sure that they will not harm us.
