Oxygen cylinders should be painted sky blue and labeled oxygen in black as follows:
1. Oxygen cylinders are usually painted sky blue and labeled "Oxygen" in black on the cylinder. This is to minimize miscalculation and confusion and to ensure that the user can clearly identify the oxygen cylinder and follow the correct method of use.
2. Sky blue is often used as an identification color for oxygen because it is widely recognized as the color of oxygen in the medical and industrial fields. At the same time, the distinct contrast of black lettering makes oxygen cylinders easier to recognize and identify. This painting and marking specification may vary from country to country and region to region, so it is best to refer to local regulations and standards in specific cases.
Oxygen cylinder safety precautions are as follows:
1, oxygen cylinders should check the inspection certificate. And the certificate of conformity should be marked with the bottle number, working pressure and test pressure next test pressure date and other information. Oxygen cylinders, must first external inspection, but also to identify the gas composition of the bottle laboratory, do not charge at random.
2, cylinders and motors in the same site use, the bottom of the bottle should be padded with insulation to prevent the cylinder charged. Pipes and equipment in contact with gas cylinders should be grounded to prevent combustion or explosion due to static electricity.
3, winter use of gas cylinders, available hot water or steam thawing. Strictly prohibit the use of fire or knocking with an iron bottle also can not be screwed pressure reducer week section, in order to prevent a large amount of gas rushed out of the accident.
4, in the preparation and use of the process, should avoid violent vibration and impact, light loading and unloading, is strictly prohibited from the height of the next or rolling cylinders on the ground. Can not be transported with combustible gas cylinders, oil and other combustible materials together.
5, the oxygen cylinder should be far away from high temperature, open fire and molten metal splash, operation of the oxygen cylinder should be more than 5m away from the ethanol cylinder. It should be covered when used outdoors in summer, and should not be exposed to the sun.
6, open the gas should be slow, anti-static sparks and adiabatic compression. Oxygen cylinders can not be all exhausted, should leave a surplus of 0.2 ~ 0.3MPa, so that the oxygen cylinder to maintain positive pressure, and close the valve to prevent gas leakage. The purpose is to prevent the backflow of combustible gases into the bottle, but also in the inflatable to facilitate the gas composition of the bottle.
7, shall not use more than should be checked period of the cylinder. Oxygen cylinders in the process of use, must be in accordance with the provisions of the safety rules every three years for a technical inspection. If found overdue for the end of the test cylinder, shall not be used. Oxygen cylinders shall not be attached to the grease, shall not be sticky with grease tools, gloves or oil stained overalls, etc. contact with the bottle valve and pressure reducing valve.
