Environmental suit

An environmental suit is a special kind of clothing that helps people stay safe and healthy when they are working in a place that is not safe for their body. The suit is made out of a special material that protects against things like harmful chemicals, bacteria, and viruses. It also helps to keep you cool or warm depending on the temperature outside. The suit is usually bright so that you are easily seen in case of an emergency.
