EPA list of extremely hazardous substances

The EPA list of extremely hazardous substances is like a list of different things that are very dangerous. The EPA, which stands for Environmental Protection Agency, is a group of people who are in charge of making sure that the environment and people are safe from things that could be harmful.

The list includes things like chemicals and gases that are really bad for people and can cause them to get sick or hurt if they are exposed to them. It's important for people to know what's on this list because if any of these things aren't handled carefully, they could cause a lot of harm.

Some of the things on the list are things that you might hear about in your science classes, like chlorine and sulfuric acid. Others might seem less dangerous at first, like potassium hydroxide, which can be found in cleaning products. But if people don't use these things correctly, they can cause a lot of damage.

So, the EPA list of extremely hazardous substances is basically a list of things that we need to be extra careful with, because they could hurt people or the environment if we don't handle them properly.
