Hazardous materials are things that can be very dangerous or harmful to people and the environment. They can be things like chemicals, gases, liquids, or even objects that can hurt us.
Imagine you have some super cool toys that you love to play with. But some of those toys can be dangerous and you need to be careful with them. For example, if you have a toy car with small parts that you can swallow, you need to be careful not to put them in your mouth. In the same way, some materials can be very dangerous if they get into our bodies or if we touch them.
Hazardous materials can be harmful in different ways. For example, some materials can be poisonous, which means they can make us sick or even kill us. Others can be flammable, which means that they can catch fire very easily and cause explosions. Some can cause a lot of damage to the environment, like oil spills in the ocean or chemicals that pollute the air.
So, it's important to be very careful when dealing with hazardous materials. This means using proper equipment like gloves or masks to protect ourselves from harm, following instructions carefully to avoid accidents, and knowing what to do in case of an emergency. It's always better to be safe than sorry!
