klorgass

Klorgass is a term used in science fiction and gaming to denote a toxic chlorine-like gas. In many works, it functions as a plot device representing a dangerous, disseminable chemical agent. The naming suggests a compound or class of gases that is heavy, irritant, and capable of rapid dispersal, drawing on real-world chlorine chemistry for flavor.

Depictions describe klorgass as a colorless or pale-yellow, dense gas with a sharp, suffocating odor. When released, it irritates the eyes, throat, and lungs, causing coughing, chest tightness, and shortness of breath. It is often portrayed as persisting in enclosed spaces and reacting with moisture to form acidic byproducts, akin to chlorine gas.

Because klorgass is fictional, there are no real production methods, safety standards, or regulatory frameworks. In-universe, responses include evacuation, respiratory protection, and decontamination. The gas is primarily used to illustrate the hazards of chemical accidents or warfare in speculative settings. The term is sometimes used loosely to refer to any chlorine-like irritant gas in fiction. See also chlorine gas, choking agents, and chemical warfare in fiction.
