Oxygen - O2
Oxygen - O2
This page brings together the main information on the Dioxygen (O2) or "oxygen" as its physical characteristics, its health effects, the means to detect it (gas detector O2 or rather O2 lack detector) as well as adapted respiratory protection equipment (insulating respiratory equipment or air supply system).
Main characteristics of oxygen (O2)
The Dioxygen (O2) more simply called " oxygen Is an existing gas in the free state in the atmosphere, of which it is approximately one-fifth of the volume and essential for most forms of life on earth. It's a gas highly reactive Easily forms compounds (in particular oxides) with most elements, except noble gases such as helium or neon.
Effects of oxygen on health
Oxygen (O2) is a gas colorless, odorless and without flavor that composes 20.9% of the air we breathe. Unlike the vast majority of the gases, the lower the oxygen concentration (O2), the more healthy the effects are on health. In medicine, it is administered in inhalations, mainly in cases of asphyxia, carbon monoxide poisoning, acute lung edema, etc. It is not measured in ppm but in% volume.
O2 gas detectors (oxygen)
Colorless and odorless, so absolutely undetectable by the organizationOnly one O2 gas detector (oxygenmeric like a 4 Gas Detector Portable) The oxygen concentrations in the air can be precisely measured, so we will move towards an oxygen detection in% volume.
For calibration and gas tests of your fixed or laptop gas detectors, oxygen standard gas cylkets are available.
Respiratory equipment for poor oxygen (O2)
Any filter respiratory protections being ineffective to bearing the lack of oxygen, we will therefore move towards an insulating respirator or a system with air supply for long time interventions.
