Protective clothing is an important part of many jobs, and can include items such as aprons, bibs, and coveralls. An APRON is a garment worn over the front of the body and tied at the back, usually made of cloth or plastic. A bib is a piece of clothing that covers the chest and is often used by babies and young children. Coveralls are a type of overalls, which are one-piece garments with long sleeves and legs, typically made of cotton or polyester. All of these items provide protection from dirt, dust, and other hazards in the workplace.
