Is Argon Poisonous? No! But, if you breathe it in it replaces Oxygen so you will suffocate from breathing it in

begin quotes:

Argon is not toxic and does not react with the body, but it is a dangerous simple asphyxiant because it displaces oxygen. Inhaling high concentrations in confined spaces can cause suffocation, dizziness, nausea, or death without warning. It is widely used in industry as an inert shield gas. 

Key Safety Information regarding Argon:

• Asphyxiation Hazard: Argon is odorless and colorless, making it impossible to detect without equipment. When it displaces oxygen below 19.5% in air, it creates a hazard.
• No Chemical Toxicity:
  It is an inert noble gas that does not damage organs directly or cause chemical poisoning.
Confined Space Danger: It is slightly denser than air, which means it can accumulate in low-lying areas in confined spaces, displacing breathable air.
Industrial Use: It is commonly used in welding, food preservation, and, at times, in clinical settings.
Signs of Oxygen Deficiency: If oxygen levels fall too low, effects can include rapid breathing, confusion, loss of consciousness, and death. 

When working with argon, ensure proper ventilation and follow industrial safety guidelines for handling gases, as described in the OSHA Respiratory Protection Standard.
