👉 A permit fluid, also known as a permit liquid or permit carrier, is a specialized liquid solution used in various industrial processes to transport and carry hazardous chemicals, particularly those that are highly reactive or toxic. It is designed to prevent the direct contact of these dangerous substances with equipment, personnel, and the environment by acting as a protective barrier. The permit fluid typically consists of inert gases like nitrogen or argon, which displace the hazardous chemicals and create a non-reactive environment. This ensures safe handling, storage, and transportation of volatile or reactive substances, minimizing the risk of leaks, spills, and accidents.
