This problem is not entirely well known to managers engaged in handling, storage and transportation. Oils, oils containing unsaturated fatty acids, are easily vaporized and exothermic. Oil yarn head. Spontaneous combustion of tarpaulins is due to oxidation in the air, and when the spontaneous ignition point is reached, it will cause spontaneous combustion. The oil and gas in the air is slow, the heat generated is dissipated quickly, and it is generally not easy to spontaneously combust. Since pure oxygen has strong oxidizing properties, it can promote the vigorous combustion of combustibles. When the oil encounters pure oxygen, the vaporization rate is greatly accelerated, releasing a large amount of heat. The temperature rises rapidly and can quickly cause combustion. If the mouth of the oxygen cylinder is stained with oil, when the oxygen is rapidly sprayed out, the oil quickly undergoes oxidation reaction, and the heat generated by the friction between the high-pressure air flow and the bottle mouth further accelerates the oxidation reaction, and the oil on the oxygen cylinder or pressure reducing valve will cause combustion and even **, which is why the oxygen cylinder, especially the bottle mouth and accessories in contact with oxygen, are strictly forbidden to contact the oil.
Therefore, in the process of storage, transportation and use, what measures should be taken to prevent oil pollution such as oxygen cylinders?
1.Oxygen cylinders and warehouses where oxygen is stored should have a strictly forbidden oil sign to remind people that, in addition to oxygen cylinders that are not allowed to come into contact with oil, include accessories that come into contact with oxygen (such as pressure reducing valves) welding torches. gas hoses, etc. ), should not come into contact with grease.
2.Warehouses and transport vehicles where oxygen cylinders are stored are strictly prohibited from being stored together with grease and grease items. Same transport. Such as warehouses. If the vehicle is contaminated with oil, it should be completely removed before storage or shipment.
3.Oxygen cylinders are being stored. During transport, wear a hard hat to prevent grease or dust from entering or mechanical damage to the nozzle of the oxygen cylinder.
4.For use. Storage and transportation operations and management personnel shall not wear oil-contaminated work clothes. Gloves and other contact with oxygen cylinders and their accessories. 5.If the cylinder is contaminated with oil, it should be wiped with carbon tetrachloride or detergent in time, but not with a combustible organic solvent.
