Safety electricity and safety fire protection measures for welding and cutting operations

When using World-Washington fire rescue cutting saws or other cutting and welding equipment for rescue, rescue personnel must pay attention to electricity safety, fire prevention, and mechanical injury to prevent secondary injuries to the rescued and tool users themselves when using such tools. Security. The following is a breakdown of welding equipment used by China Rescue Equipment Network for electricity safety, fire safety, and safety against mechanical damage.

Fu Shihua cutting saw

First , cutting and welding equipment

( 1 ) Workers must be trained through security techniques, assessments, and certificates.

( 2 ) Work clothes, insulated shoes, welding gloves should be worn during operation and kept dry and clean.

( 3 ) Before starting the welding work, check whether the welding machine and tools are intact and safe. Such as welding clamp and welding cable insulation is damaged. Welder shell grounding and welder contact points are good contact.

( 4 ) When the workplace is wet, the floor should be covered with rubber sheet or other insulating material.

( 5 ) When the clothes are wet after the body sweats, do not rely on the charged steel plate or work piece to release the electric shock.

( 6 ) In the case of electrification, for safety reasons, the welding pliers must not be clamped to carry the welded workpiece or hang the welding cable around the neck.

( 7 ) It is not allowed to face the switch when pushing the knife directly to face, in order to prevent the spark caused by the short circuit from burning the face.

( 8 ) When working in cramped spaces, cabins, containers and pipes, in order to prevent electric shock, insulated shoes must be worn, rubber sheets or other insulating liners should be placed under the feet; it is advisable that two people work alternately to take care of each other. Otherwise, a guardian is required to pay attention to the safety of the operator at any time. In the event of a dangerous situation, he will immediately cut off the power to rescue him.

( 9 ) Always wear leather gloves when replacing the electrode. Do not use bare hands.

( 10 ) The following operations must be performed after the power is turned off:

When changing the welder's joint: When replacing the weldment requires the secondary circuit; when the welder fails, it needs to be repaired; when the work place is moved to move the welder; when the work is completed or temporarily left the work site.

Second , cutting and welding equipment fire safety

( 1 ) Inflammable and explosive materials shall not be piled within 10M around the welding operation site .

( 2 ) When operating at a high altitude, the oxygen cylinder and liquefied gas must not be placed directly under the work area, and should be kept at a distance of more than 10M directly below the work . The flammable material below the work area must be removed.

( 3 ) When igniting the welding (cutting) torch, first open the acetylene valve to ignite, and then open the oxygen cylinder valve to adjust the flame. Close should close the acetylene valve first and then close the oxygen valve

( 4 ) If the oxygen tube catches fire during the operation, the oxygen valve should be closed immediately, and the hose should not be broken. If the acetylene tube is on fire, the torch should be turned off first. Use a method of bending the front hose to stop the fire.

( 5 ) During ignition, the torch mouth must not be facing the person. Do not place the burning torch on the workpiece or the ground. Torch with acetylene gas and oxygen must not be placed in metal containers.

Third, cutting and welding equipment to prevent mechanical damage and safety

1 . Persons who do not understand electrical appliances and machinery are strictly prohibited from using and playing with mechanical and electrical equipment.

2. The mechanical and electrical equipment is intact and must have a safety protection device.

3 . Electrical and mechanical equipment must be turned off and shut down in accordance with regulations and requirements when it is out of power, or when work is suspended.

4 . Mechanical and electrical equipment to achieve fixed operation, fixed maintenance, inspection, fixed machine management, regular maintenance.

5. Electromechanical equipment is not allowed to run sick, and no overload operation is allowed. It is also not allowed to maintain during operation.
