What does the EPA define as preventing any measurable amount of material from passing through fabric?

The Environmental Protection Agency (EPA) defines "chemical resistant" as the ability to prevent any measurable amount of material from passing through fabric. This is crucial in the context of herbicide application, where workers must be protected from hazardous substances that could penetrate through clothing or other protective gear.

Chemical resistance is essential for safety equipment such as gloves, suits, and boots, which are designed to keep harmful chemicals from reaching the skin and causing potential health risks. This means that the fabric must be specially designed and treated to resist the permeation of particular chemicals, ensuring full protection during handling and application processes.

Other terms such as "puncture-resistant," "biodegradable," and "waterproof" might refer to different attributes of materials. For instance, puncture-resistant materials protect against physical injuries, biodegradable refers to the ability of a material to decompose naturally, and waterproof indicates that a material can resist water penetration. However, these qualities do not directly address the prevention of chemical penetration, which is the core definition provided by the EPA.
