selection and installation requirements of medical liquid oxygen storage tank (i)
according to the requirements of article 4.3.4 of code for fire protection design of buildings, the requirements for the installation of liquid oxygen storage tanks in hospitals are specified accordingly; the fire separation distance between liquid oxygen storage tanks and buildings, storage tanks, storage yards, etc. shall comply with the provisions on fire separation distance of corresponding volume wet oxygen storage tanks in article 4.3.3 of this specification. the distance between liquid oxygen storage tank and pump house shall not be less than 3m. total volume less than or equal to 3m ³ the fire separation between the liquid oxygen storage tank and the building used shall comply with the following provisions:
1. when it is set in an independent special building with class i and ii fire resistance rating, the fire separation shall not be less than 10m;
2. when it is set in an independent special building with class i and ii fire resistance rating, and the side facing the building is separated by a firewall without door and window openings, the fire spacing is unlimited;
3 when fire prevention measures are taken for liquid oxygen storage tanks stored at low temperature, the fire prevention distance shall not be less than 5m.
medical liquid oxygen storage tanks in medical and health institutions and liquid oxygen storage tanks in gas supply stations shall meet the following requirements:
1. the volume of single tank shall not be greater than 5m ³， the total volume should not be greater than 20m ³；
2. the distance between adjacent storage tanks shall not be less than 0.75 times the diameter of the largest storage tank;
3 the fire separation distance between the medical liquid oxygen storage tank and the buildings outside the medical and health institutions shall comply with the provisions of article 4.3.3 of this code, and the fire separation distance between the medical liquid oxygen storage tank and the buildings inside the medical and health institutions shall comply with the provisions of the current national standard technical code for medical gas engineering (gb 50751).
when determining the fire prevention distance between the liquid oxygen storage tank and other buildings, storage tanks or storage yards, the volume of the liquid oxygen storage tank shall be 1m ³ liquid oxygen is converted to 800m ³ after oxygen in standard state. for example, there is one 100m in a factory ³ for the liquid oxygen storage tank, it is first converted to 800 × 100=80000（m ³） oxygen in accordance with the third gear (v > 50000m) of article 4.3.3 of this specification ³） determine the fire spacing of liquid oxygen storage tank according to the provisions of.
