Which type of clothing should not be used by responders in a hazardous materials incident?

Highly permeable fabrics should not be used by responders in a hazardous materials incident because they allow contaminants to pass through easily, thereby exposing the wearer to hazardous substances. In the context of hazardous materials response, clothing must act as a barrier to protect individuals from chemicals, biological agents, and other dangers present in the environment.

On the other hand, reusable protective gear is designed to provide a high level of protection and can be decontaminated for future use, making it suitable for responders. Disposable chemical suits are specifically manufactured for one-time use in hazardous situations and effectively shield against chemical exposure. Fire-resistant uniforms, while primarily intended for heat and flame protection, generally provide a certain degree of durability and can be suitable depending on the incident's nature. The key point is that the clothing worn during such events needs to ensure safety and prevent penetration of harmful substances, which permeable fabric fails to provide.
