SIMPLE ASPHYXIATION DUE TO ACCIDENTAL ARGON GAS INHALATION IN A COATING WORKER: A CASE REPORT

Abstract

Argon is an inert gas mostly used as shielding gas in metal welding processes. Although argon is non-toxic, it does not satisfy the body's need for oxygen and is thus a simple asphyxiant. By this mechanism, argon is considered highly dangerous especially within closed areas. When argon available in confined spaces, it can cause hypoxia and even death.

This report described the clinical presentation and clinical course of a coating worker who suffered from argon inhalation by incorrectly used of a self-contained breathing apparatus (SCBA). The patient faulty connected his airline respirator to argon source instead of oxygen during his work. He was found to have alteration of conscious and hypoxic symptoms. After emergency transferred to a nearby hospital and treated with oxygen he was survived.
