Basic safety measures should be taken for electric welding and gas cutting

4. The length of one-time wiring of the welding machine should not exceed 3 meters

5. The length of the secondary wire of the electric welding machine shall not exceed 25 meters, and the double wire must be led to the welding workpiece. The workpiece will completely disappear in two to three years after correct operation. Grounding clamps must be used for grounding, and lapping is strictly prohibited

6. Check whether the primary and secondary cable skins are damaged

7. Fireproof Blanket or fireproof bedding shall be used for electric welding, which shall be laid on the platform or under the equipment to prevent sparks from falling and splashing

8. Before hot work, two bottles of 4kg qualified dry powder fire extinguishers shall be equipped

9. Before hot work, clean the combustibles in the operation area

10. After the work is completed, confirm that the fire has been extinguished and leave after the site is cleaned

II. Safety measures for gas cutting work:

1. Prevent burns, wear welder's clothing, wear welder's special gloves and insulating shoes

2. Wear protective glasses when knocking welding slag

3. The shockproof ring of oxygen and acetylene bottles shall be placed vertically, bound and fixed, and the bottom of the bottle shall be padded with rubber; The distance between the two bottles is more than 8 meters and more than 10 meters from the hot work point

4. Check that the oxygen and acetylene pressure gauges are normal, the acetylene flasher is normal, and the oxygen and acetylene belts are not damaged

5. Fire proof blankets or suitable bedding shall be used for gas cutting operations, which shall be laid on the platform or under the equipment to prevent sparks from falling and splashing

6. Before hot work, two bottles of 4kg qualified dry powder fire extinguishers shall be equipped

7. Before hot work, clean the combustibles in the operation area

8. After the work is completed, confirm that the fire has been extinguished and leave after the site is cleaned

III. safety measures for electric welding and gas cutting:

1. Prevent burns, wear welder's clothing, wear welder's special gloves and insulating shoes

2. Wear protective glasses when knocking welding slag

3. Welding arc hurts eyes, avoid looking at the welding light, and require the welder to give prompt

4. The primary wiring length of the welding machine shall not exceed 3 meters

5. The length of the secondary wire of the electric welding machine is not more than 25 meters, and the double wire must be led to the welding workpiece. The workpiece must be grounded with a grounding clamp, and it is strictly prohibited to overlap

6. The shockproof ring of oxygen and acetylene bottles shall be placed vertically, bound and fixed, and the bottom of the bottle shall be padded with rubber; The distance between the two bottles is more than 8 meters and more than 10 meters from the hot work point

7. Check whether the oxygen and acetylene pressure gauges are normal and the acetylene flasher is normal. Check whether the primary and secondary cable sheaths, oxygen and acetylene belts are damaged

8. Fire proof blankets or suitable bedding shall be used for gas cutting operations, which shall be laid on the platform or under the equipment to prevent sparks from falling and splashing

9. The tensile force required when the dynamic heat sealing sample breaks under the action of tension. Before the fire, two bottles of 4kg dry powder fire extinguishers with qualified quality shall be equipped

10. Before hot work, clean the combustibles in the operation area

11. After the work, confirm that the fire factor needs to pay attention to the selection of materials, the design of plastic parts, the prediction and optimization of mechanical properties, etc. the species have been extinguished, and the site can be cleaned before leaving

IV. other conditions:

1. Isolation measures between hot work equipment and inflammables and explosives (cables, oil, wood products, plastics, etc.)

2. Other aspects (oil pipeline cleaning, hydrogen pipeline replacement, etc.)

v. provisions on the concentration of combustible gases and dust:
