Which risk increases when cryogenic liquid nitrogen leaks into a closed room at standard temperature?

💡 Explanation

When liquid nitrogen leaks into a closed room it undergoes a rapid phase transition to gaseous nitrogen through rapid heat absorption, displacing the existing oxygen because nitrogen is heavier than air, leading to asphyxiation. Therefore asphyxiation risk increases, rather than combustion as nitrogen is inert, structural damage occurs over long exposure and electrical interference is not applicable.
