What material can chemical-resistant personal protective equipment (PPE) be made of?

Chemical-resistant personal protective equipment (PPE) is specifically designed to protect users from exposure to hazardous chemicals. The correct choice, which mentions PVC (polyvinyl chloride) and rubber, is particularly relevant because these materials are known for their ability to effectively resist a wide range of chemicals.

PVC is often used in gloves and aprons because it provides a barrier against both liquid and solid chemicals, preventing penetration and thus protecting the skin from harmful substances. Similarly, rubber is widely utilized in items like boots and gloves, as it is resilient and resistant to many types of chemicals, including acids, bases, and solvents.

The other materials in the incorrect options lack the necessary resistance to chemical exposure. Cotton and wool, for example, are organic fibers that absorb moisture and do not provide an effective barrier against chemicals. Nylon and mesh also do not offer the protective qualities needed for chemical safety, as they can be permeable to certain substances. Lastly, while polyester is more durable than cotton, it does not possess the same level of chemical resistance as PVC and rubber, and leather can absorb chemicals, making it unsuitable for protective gear against hazardous materials.
