Okay kiddo, let me tell you about the hierarchy of hazard controls. Basically, when we are doing something, like playing with toys or using machines, there might be dangers that can hurt us. A hazard is like something that can cause harm or danger. So, what we need to do is to try and eliminate or reduce the hazard as much as possible. And the hierarchy of hazard control is like a list of different ways we can do that.
The first way to control hazards is by eliminating them altogether. This means taking away the thing causing the hazard so that you can't get hurt by it. For example, if you are playing with a sharp knife or scissors, an adult can take them away from you or put them out of reach so that you can’t hurt yourself.
The second way is to substitute the hazard with something that is safer. This means replacing the dangerous thing with something that is not dangerous. For example, if you want to cut something but don't want to use a sharp knife, you can use safety scissors that are not as sharp.
The third way is to use engineering controls, which are things that are built or designed to stop you from getting hurt. For example, a fence around a swimming pool or a guard around a machine that can cut or crush your fingers.
The fourth way is to use administrative controls, which means setting up rules or procedures to keep you safe. For example, if you're riding a bicycle, someone might tell you to wear a helmet, so you don't hurt your head if you fall off.
The fifth and last way is to use personal protective equipment (PPE), which is like special clothing or gear that you wear to protect yourself. For example, when you play hockey or ride a skateboard, you wear a helmet, knee-pads, and elbow-pads to prevent injuries.
So, that's the hierarchy of hazard controls. By eliminating or reducing dangerous things and using different types of controls, we can play and work safely without getting hurt.
