Oxygen bottles, acetylene bottles use safety measures

First, the use of oxygen cylinders need to take safety measures

To ensure safety, the following measures should be taken when using oxygen cylinders:

1. Look carefully at the spherical part of the cylinder's shoulder before use. Pay special attention to the next test time. And in the course of use, the gas cylinders are regularly tested as required. Do not use cylinders that exceed the inspection period.

2 , when used, first of all do an external inspection, check the key is the bottle valve, take over the thread, pressure reducer and so on. If there is any leakage, slippery buckle, hand movement or climbing, etc., it shall be repaired in time and should not be handled arbitrarily. Do not tighten the valve stem with pressure and adjust the gasket material. Check for leaks with soapy water and do not use open flames.

3 , gas cylinders and welding in the same field, the bottom of the bottle should be insulated, in order to prevent the cylinder charged. Pipes and equipment that come into contact with gas cylinders must be grounded to prevent them from burning or exploding due to static electricity.

4. When using cylinders in winter, bottle valve or pressure reducer may be frosted, or thawed with hot water or steam. Do not use fire to bake or knock on bottle valve with iron, nor can you adjust the adjustment of regulator Screws to prevent accidental discharge of gas.

5. During use and storage of cylinders, severe vibration and impact should be avoided.

Handling gas cylinders must be lightly loaded and unloaded. Special lifting racks or small carts must be used. It is forbidden to directly use oxygen cables such as steel ropes. When used and stored, use a railing or bracket to fix the cylinder to prevent tipping.

6. The oxygen cylinder should be kept away from high temperature, open flame and molten metal spatter ( more than 10 meters apart ). It should not be exposed to the hot sun during summer use.

7. When the bottle valve or pressure reducer is opened, the action should be slow to prevent the discharge of static spark discharge in the high-speed air stream, the collision heat and friction heat of the solid particles, the heat released by the sudden compression of the gas (adiabatic compression), etc. Bottle and pressure reducer explode on fire.

8. The oxygen in the oxygen bottle can not be used up completely. The remaining gas should be 0.2 to 0.3 MPa, so that the gas bottle can maintain a positive pressure, and the valve can be closed to prevent air leakage. The purpose is to prevent the inflow of combustible gas into the bottle and to facilitate testing of the gas composition in the bottle when inflated.

9. The oxygen cylinder valve must not be contaminated with grease, and must not touch the bottle valve and pressure reducer with tools, gloves, or oil stains, etc. that are stained with grease.

10. The above safety measures are basically applicable to other cylinders used in welding processes such as argon cylinders and plasma arc welding, such as argon cylinders and nitrogen cylinders.

Second, the use of acetylene bottles need to take safety measures

The safety measures for using acetylene bottles are as follows:

1 , ( 1 ) to ( 5 ) with the use of oxygen cylinder safety measures .

2 , must use qualified acetylene special pressure reducer and temper preventer.

3 , the bottle surface temperature must not exceed 40 °C (hand touch some hot), should immediately stop using, after taking the water to cool and properly handle, send inflatable unit inspection.

4. The acetylene bottle can only stand upright when it is stored and used. It cannot lie horizontally to prevent the acetylene from flowing out and cause explosion.

5. The acetylene bottle should stand still for about 15 minutes after standing upright in order to use the regulator. When opening the valve of the acetylene bottle, do not exceed one and a half laps, and only a maximum of 3 to 4 turns.

6. The indoor space where acetylene bottles are stored should be ventilated and ventilated to prevent the leakage of acetylene gas and form explosion air masses.
