caption_attribution_description: English: Normal air (on the left pie chart) vs. normobaric hypoxic atmosphere (on the right pie chart): the concentrations of nitrogen and oxygen are different.
context_page_description: Hypoxic air technology for fire prevention, also known as oxygen reduction system, is an active fire protection technique based on a permanent reduction of the oxygen concentration in the protected rooms. Unlike traditional fire suppression systems that usually extinguish fire after it is detected, hypoxic air is able to prevent fire.
