What hazard is associated with the penetration of protective suits?

The penetration of protective suits specifically refers to the ability of hazardous materials to break through the material of the suit, allowing contaminants to reach the skin or body. This is accurately described by the term "penetration," which signifies that a substance directly passes through a barrier—in this case, the protective suit.

While degradation refers to the deterioration of the suit's material, permeation signifies the process where hazardous materials dissolve and diffuse through the suit at a molecular level, without actually breaking through. Exposure involves coming into contact with hazardous materials, but it does not specifically address how a suit might fail in its protective function. Thus, understanding penetration as a hazard emphasizes the importance of suit integrity and the need for proper materials that can resist environmental threats without allowing harmful substances to breach the protective layer.
