Is the oxygen content in the room air reduced? If the oxygen content in the room air is reduced, much more energy is required to ignite a fuel. The energy required to ignite it is higher than that required to sustain a fire.
How is oxygen reduction used?
In this process, depending on the materials stored or the equipment to be protected, the oxygen content of the air in the room is reduced to prevent a fire from breaking out. In common parlance, this technology is called a fire prevention or oxygen reduction system.
What is the oxygen reduction for healthy individuals?
The reduction in oxygen content to, for example, 15% by volume achieved by the active fire prevention system with the aid of nitrogen corresponds roughly to atmospheric conditions at an altitude of 3,000 meters. A reduction in oxygen is therefore harmless to healthy persons, provided certain precautions are taken.
What is the nitrogen for oxygen reduction?
The nitrogen for oxygen reduction is generated by the active fire prevention system through a nitrogen generator or via a fuel cell (whose natural low-oxygen exhaust air has a high nitrogen content) directly on site.
How can the nitrogen needed for oxygen reduction be obtained? Due to the high nitrogen content in the ambient air, the nitrogen required to operate the oxygen reduction plant can be obtained directly on site using a generator.
How can they measure the oxygen?
Measure oxygen: With the air-Q measuring device, you can measure oxygen, but also all other relevant components of the room air, such as carbon monoxide. As a particularly powerful and comprehensive device, the air-Q air analyzer has sensor technology that can measure the O₂ content of the room air.
Which measuring devices are responsible for oxygen contents? These are not to be confused with so-called oximeters, which are responsible for measuring the oxygen content in the blood. The measuring devices, which can determine the oxygen in the air, are available in different versions, for the layman as well as for the professional user.
What is oxygen deficiency in the air?
Instead of a lack of oxygen, the increasing carbon dioxide content makes thinking more difficult. This is due to the different ratio of oxygen and carbon dioxide in the air we breathe in and out. Fresh air contains about 21 percent oxygen, but only 0.04 percent carbon dioxide (CO2).
What air produces the oxygen reduction?
The nitrogen or nitrogen-enriched air for oxygen reduction is generated by the active fire prevention system by means of a nitrogen generator or via a fuel cell (whose natural low-oxygen exhaust air has a high nitrogen content) directly on site.
What is oxygen in closed systems?
In closed systems, it is oxygen in particular that poses a danger: it undergoes a chemical reaction relatively quickly. Corrosion can thus occur on old steel pipes or other metallic components, resulting in the formation of rust or sludge. The result is reduced plant performance.
How does oxygen reduction work in larger bodies of water?
Oxygen reduction at higher altitudes also plays an important role for extreme mountaineers. With the help of an oxygen mask, they can boost their performance at higher altitudes and protect their health. The same applies to divers in deeper waters.
How does oxygen production decrease in the water body? The plants release oxygen through tiny pores. This rises to the water surface in the form of small bubbles. The more algae grow in the water, the higher the oxygen production. This occurs cyclically, because at night the plants consume large amounts of oxygen.
Is the oxygen in flowing water better than stagnant water? Flowing waters generally have a greater self-purification capacity than standing waters, since the oxygen input by diffusion from the air is usually better in flowing waters, especially at rapids.
How does the separation of the oxygen molecules take place? In these fibers, the separation of oxygen and nitrogen molecules takes place: The oxygen molecules diffuse through the fiber walls, while the larger nitrogen molecules flow through the fiber. The nitrogen obtained is fed into the protected area via a network of pipes.
What is an oxygen meter for the air in the apartment?
An oxygen meter for the air in the apartment is therefore very useful so that targeted countermeasures can be implemented. These include, for example, regular ventilation, an air purifier or plants in the room. Often, the air quality can be directly classified by means of a traffic light display.
What are possible damages caused by oxygen?
Possible damage caused by oxygen depends primarily on the pressure. DGUV Rule 113-004 for occupational safety specifies a value of 17 % oxygen. The exhaled air of a person still contains approx. 16 % oxygen. The oxygen concentration of the air breathed in beforehand averages around 21 %.
What is oxygen on the earth's surface?
On the Earth's surface, oxygen is the most abundant element - by mass. Can be measured with: Almost all animal life forms require oxygen to live. It is absorbed by respiration or, if dissolved in water, by resorption. In high concentrations, however, oxygen is toxic to most living organisms.
What factors influence oxygen content in enclosed spaces?
But there are also other factors that influence the oxygen content in enclosed spaces. These include wood-burning stoves, for example. Since, depending on the stove, output and efficiency, any amount of oxygen is burned during the combustion of wood, a sufficient supply of fresh air must be ensured.
