The precautions for the use of oxygen piping in wards are: first, to comply with the requirements of the fire distance; second, the piping material must meet the requirements and be equipped with piping equipment.
1, in line with the fire distance requirements
Because of the flammability of oxygen, for safety reasons, liquid oxygen tanks and pipelines should be in line with the current state of the relevant provisions of the fire distance , healthcare Institutions liquid oxygen storage tanks at the height of the physical enclosure can not be less than 2.5m; when the enclosure outside the road or open space, storage tanks and physical enclosure spacing can not be less than 1m; enclosure outside the buildings, structures, storage tanks and physical enclosure spacing should not be less than 5m.
2, pipeline materials must meet the requirements and equipped with pipeline equipment
Oxygen pipeline generally use degreased copper pipe and 304 stainless steel pipe , and in each floor ward installation of valves, optional installation of secondary decompression tanks, flowmeters and pressure alarms and other pipeline equipment. The company also uses oxygen specialties for all connecting accessories.
Basic properties and role of medical oxygen in the ward:
Medical oxygen is one of the components of air, colorless, odorless, tasteless. Medical oxygen density than air, in standard conditions (0 ℃ and atmospheric pressure 101325 Pa) under the density of 1.429 g / liter.
All oxidation reactions and combustion processes require oxygen, such as steelmaking in addition to sulfur, phosphorus and other impurities, oxygen and acetylene mixture combustion temperature of up to 3500 ℃ for steel welding and cutting. Oxygen is required for glass manufacturing, cement production, mineral roasting, and hydrocarbon processing. Liquid oxygen is also used as rocket fuel, which is cheaper than other fuels.
Working in a low-oxygen or oxygen-deficient environment, such as divers, astronauts, medical is indispensable to maintain life. However, the active state of oxygen, such as OH and H2O2, etc. on the organization of living creatures have serious damage, ultraviolet radiation on the skin and eye damage is mostly related to this effect.
