Fire can be prevented, utilising Controlled Atmosphere technology, unlike traditional fire suppression systems are designed to automatically extinguish fires upon detection of a fire event. PYROGEN PYROprevent hypoxic fire prevention system literally prevents fires from occurring in protected areas by continuously monitoring and maintaining the proportion of Oxygen to Nitrogen in the enclosure – so that it is not even possible for fire to ignite.
Effects on Health
Hypoxic air according to some medical studies area considered to be safe to breathe for most people. Medical studies have been undertaken on this topic. Angerer, Peter; Nowak (March 2003) conclusion is that “working environments with low oxygen concentrations to a minimum of 13% and normal barometric pressure do not impose a health hazard, provided that precautions are observed, comprising medical examinations and limitation of exposure time“. Kupper Thomas say that oxygen concentration between 17.0-14.8% does not cause any risk for healthy people by hypoxia. It also does not cause risks for people with chronic diseases of moderate severity.
Pressurized aircraft cabins are typically maintained at 75kPa, the pressure found at 2500 m altitude, resulting in an oxygen partial pressure of about 16 kPa, which is the same as a 15% oxygen concentration in a hypoxic-air application at sea-level pressure.
Hypoxic air is to be considered clean air and not contaminated air when assessing oxygen depletion hazards.
