What type of chemical-protective clothing is designed to totally enclose the wearer?

The type of chemical-protective clothing designed to totally enclose the wearer is the encapsulating suit. This suit provides a high level of protection by completely sealing off the wearer from hazardous materials, ensuring that no chemicals can penetrate the fabric or reach the skin. Encapsulating suits are particularly important in environments where the risk of exposure to toxic substances is significant.

These suits are typically made with durable materials that resist permeation and degradation by a wide range of chemicals. They incorporate features such as sealed seams, airtight zippers, and an air supply system to maintain a safe and breathable atmosphere for the wearer within the suit.

In contrast, aprons, coveralls, and chemical splash suits offer varying levels of protection but do not fully encapsulate the body. Aprons cover only the front of the wearer and do not provide protection for the entire body. Coveralls offer more coverage than aprons but still do not completely enclose the wearer. Chemical splash suits protect against accidental splashes but may not provide the same level of containment or air supply as encapsulating suits. Therefore, the encapsulating suit is the only option that fully meets the requirement of completely enclosing the wearer while providing protection against hazardous substances.
