Oxygen reduction system

Okay kiddo, you know how we need oxygen to breathe, right? Well, some special machines also need oxygen to work but they don't use it the same way we do. Instead, they use it to help do a really important job called "reducing" something.

Let's say we have a fire and we want to put it out. We can use water, right? But sometimes certain fires won't go out with just water. That's where the oxygen reduction system comes in. It helps take away the oxygen that's feeding the fire, which makes the fire go out.

The oxygen reduction system is kind of like a magical machine that takes in air from the room and removes some of the oxygen from it. It does this by either adding in another gas or by filtering out some of the oxygen. This creates a special "air mixture" that has less oxygen than regular air. When that mixture is pumped back into the room, it helps prevent fires from starting and it can also make it easier to put out any fires that do start.

So, the oxygen reduction system is really important because it helps keep us safe from fires. And even though it's a big, complicated machine, it's really just doing its job by taking away some of the oxygen in the air to help us stay safe.
