Why can't oxygen cylinders, especially the mouth of the cylinder, be contaminated or in contact with oils and fats? This problem is not entirely well known to managers engaged in operational and storage operations. Oils, especially those containing unsaturated fatty acids, are easily vaporized and exothermic. Oil yarn head, oilcloth so spontaneous combustion is due to the oxidation in the air, heat accumulation does not disperse, when reach the point of spontaneous combustion caused by spontaneous combustion. The speed of oil gasification in the air is slow, the heat generated is quickly distributed, and it is generally not easy to gather heat spontaneous combustion. Because pure oxygen is extremely oxidizing, it can promote the violent combustion of combustibles. When oil meets pure oxygen, its gasification speed is greatly accelerated, and a lot of heat is released. A rapid rise in temperature will soon cause combustion. If the mouth of the oxygen cylinder is stained with grease, when the oxygen is rapidly eared, the oil rapidly oxidizes, and the heat generated by the friction of the high pressure air flow and the mouth of the cylinder further accelerates the oxidation reaction. The oil contaminated on the oxygen cylinder or the reducing valve will cause combustion or even explosion. This is the reason why the oxygen cylinder, especially the mouth and the accessories in contact with oxygen, are strictly prohibited from contacting with the oil.
So, what measures should be taken to prevent oxygen cylinders from being contaminated with grease during storage, transportation and use?
1, oxygen cylinder and storage of oxygen warehouse should be strictly prohibited grease sign, remind people to pay attention to: in addition to the oxygen cylinder is not allowed to contact grease, including oxygen contact accessories (such as reducing valve, welding torch, gas hose, etc.), can not contact grease.
2, storage warehouse and transport vehicles are strictly prohibited from storage and transport with oil and grease items. Such as storerooms, vehicles contaminated with oil, to be thoroughly removed before storage or shipment.
3, oxygen cylinder in storage, transportation to wear safety helmet, to prevent the invasion of grease or dust or oxygen cylinder mouth mechanical damage.
4, for the use, storage, operation and management personnel are not allowed to wear contaminated work clothes, gloves and other contact oxygen cylinder and accessories.
5, if the cylinder once stuck with grease substances, should be used carbon tetrachloride or cleaning agent in time to wipe, but can not be wiped with flammable organic solvents.
