A smoke hood is a special mask that you wear on your head to help protect you from smoke and other dangerous gases that can hurt your lungs. It's kind of like a helmet that covers your face and your breathing hole, so you only breathe in clean air.
If there's a fire or some other danger that's producing a lot of smoke, it can be hard to breathe, and you might start coughing or feeling sick. A smoke hood helps you breathe easier and avoid those harmful things that are in the air.
To use a smoke hood, you put it on your head like a hat and pull the straps to make sure it fits snugly. Then, you breathe in through the filter and out through the sides. Some smoke hoods even have special features like a light or a whistle to help you find your way or call for help if you get lost or stuck.
When you use a smoke hood, it's important to stay calm and follow any instructions that come with it. Remember, it's there to help you stay safe and breathe easier, so you can get to a place where there's fresh air and get out of the danger zone.
