Which hazard should be considered for nitrogen when it is a component of COTA?

• A. Fire hazard
• B. Oxygen depletion
• C. Toxicity
• D. Pressure effects

Answer: (B)

Inerting gases like nitrogen create an asphyxiation risk by diluting the oxygen in the air. Nitrogen is not toxic and does not support combustion, but when it enters a confined or poorly ventilated space, it can lower the breathable oxygen concentration enough to cause dizziness, unconsciousness, or death. That’s why the primary hazard to consider when nitrogen is a component of COTA is oxygen depletion. Other hazards aren’t the main concern here: fire isn’t a risk from nitrogen itself, toxicity isn’t an issue for nitrogen, and pressure is only a concern in terms of containment and release, not the inherent hazard of nitrogen as a component.
