WELDER'S SAFETY AND HEALTH INSTRUCTIONS
1.General safety requirements
1.1. Persons who have reached the age of 18, have completed special training, knowledge testing at the qualification commission and have received the appropriate welder's certificate are allowed to carry out welding work.
1.2. High-risk work is performed according to a work permit. Welders must have a safety qualification group of at least II.
1.3. All welding work must be carried out in places specially designated and equipped for this purpose (in booths, welding posts and outdoor areas).
1.4. The welder is obliged to: - know the rules of the internal labor regulations of the enterprise and the instructions on labor protection both in his main profession (work) and when performing related work; - do not smoke near and do not approach acetylene generators, gas cylinders, flammable liquids, materials, paint sites and paint chambers with an open flame, as this may cause an explosion or fire.; - being near oxygen cylinders, do not allow oil to get on them, do not touch them with hands contaminated with oil, since the combination of even a small fraction of oil (fat) with oxygen can cause an explosion; - do not turn on or stop (except in emergency cases) machines, mechanisms, machines that do not assigned to work; - do not touch moving parts of equipment, machines and mechanisms, do not touch electrical equipment (electrical distribution cabinets, general lighting fittings, electrical wires, tires, terminals and other live parts), do not step on portable electrical wires, hoses lying on the floor; - do not open the doors of electrical distribution cabinets (assemblies) and do not remove fences and protective covers from moving and live parts of the equipment.
Welder's Safety and Health Instructions
1.5. Persons who violate the rules of the internal labor regulations and instructions on labor protection are subject to disciplinary and financial responsibility, if these actions do not entail criminal liability.
1.6. A DC welding machine must be under the supervision of a welder, who must ensure that it is in good working order and properly operated.
1.7. Installation and repair of welding units, oscillators, their connection and disconnection from the mains in the absence of safe special switching devices, as well as supervision of operation and technical condition should be carried out by certified electricians or electricians.
1.8. The electric arc may be powered only by welding transformers, welding generators and rectifiers. Connection of welding units to the electrical network with a voltage exceeding 0.4 kV is not allowed.
1.9. To protect the body, respiratory organs and vision from the effects of welding arc rays, splashes of molten metal and other harmful and dangerous industrial factors, it is necessary to use overalls, safety shoes and other personal protective equipment (glasses, masks, respirators, dielectric gloves, boots, etc.) issued at the enterprise.
2. Safety requirements before starting work
2.1. Check and tidy up your clothes. The clothes must be serviceable, dry and not greasy. A canvas jacket should be without pockets and worn loose over trousers. Trousers should be long, worn over boots and boots and securely close them. Do not work in light shoes (slippers, sandals, etc.).
2.2. Check whether the workplace and the approaches to it are sufficiently illuminated. The illumination of the working areas at the welding sites should be at least 30 lux. The light should not blind the eyes.
2.3. Inspect and tidy up the workplace, remove all unnecessary items from under your feet if the floor is slippery (doused with oil, water, etc.), demand that it be wiped or do it yourself. Firmly lay and secure the objects (parts) to be welded. Require or remove all flammable materials within a radius of at least 15 m from the welding site or reliably protect them from sparks flying off during welding. Check for fire-fighting equipment (sand, water, fire extinguisher, etc.). 2.4. If necessary, select and coordinate with the head of work the place of installation of welding equipment.
2.5. Temporary workplaces located in open areas, workshops and sites should exclude the risk of injury from motor vehicles and other vehicles, cargo moved by lifting mechanisms, as well as due to other production factors.
2.6. The width of the free passage between single-post welding transformers, as well as the passages on each side of the welding table, must ensure safety and convenience of work, transportation of products, and repair of equipment, and must be at least 1 m. Do not install mobile welding equipment in cluttered areas.

2.7. Check the availability and serviceability of personal protective equipment and safety devices (shields, masks, dark glasses, mittens, dielectric gloves, galoshes, mats, etc.) and the operation of local gas extraction systems.
2.8. Shields, helmets and masks, as well as dielectric gloves, galoshes, mats, etc. must be free of defects (cracks, burns). It is prohibited to use household rubber, as well as expired dielectric boots, galoshes, gloves, and mats.
2.9. Protective dark glasses (light filters) in terms of transparency must correspond to the current strength (arc brightness) used in electric welding operations.
2.10. Prepare and check the necessary hand tools and accessories. When working, use only serviceable, dry and clean tools and accessories.
2.11. Check the serviceability of welding equipment and electrical measuring devices, the presence and serviceability of grounding of electrical machines and transformers. Metal housings, housings of welding installations, machines and starting electrical appliances, return wires (in places where they are connected to the secondary winding of the welding transformer), as well as welded structures and tables on which welding is performed are subject to protective grounding. It is not allowed to use the grounding of one transformer to ground another.
2.12. When grounding the housings of electric welding units or structures, first connect the grounding wire to the ground, and then to the side clamp of the unit. Disconnect the grounding in the reverse order.
2.13. Grounding of mobile traction welding units must be performed before they are connected to the mains and not disrupted until the units are disconnected from the mains.
2.14. Inspect the brushes and collector of the generator, transformer and regulator, make sure they are clean and in good working order.
2.15. Check the condition and serviceability of electrical wiring and welding wires and their connections. Electric welding wires must be flexible and have undisturbed insulation and protection against dangerous mains voltage transfer to ungrounded structures, touching which can be life-threatening.
2.16. The welding wires must be connected by hot soldering or welding, or by means of connecting couplings with an insulating sheath. Soldering and welding joints must be carefully insulated.
2.17. The length of the wires between the supply network and the mobile welding transformer should be no more than 10 m, and for step-down transformers - no more than 1.5 m.
2.18. All accessible live parts of electrical installations must be securely insulated, shielded or located in places inaccessible to touch. If the electrical equipment is faulty, call an electrician. Do not try to fix these problems yourself.

2.19. Check that the electrode holder holds the electrode firmly. The handle must be insulated, and the contact with the wire must be secure. The connection of the wire to the electrode holder and the return wire to the product to be welded must be carried out using copper cable lugs bolted together. The place where the wire is connected to the electrode holder must be insulated. When the welding current exceeds 500 A, the conductive wire must be connected to the electrode holder, bypassing its handle.
2.20. Check the availability and serviceability of starting devices, protective and safety equipment (handwheels, handles, buttons of protective covers on switches, fuses, etc.).
2.21. Check the voltage at the terminals of the generator or transformer according to the indicators of the devices - it should not exceed 115 V for DC machines and 70 V for AC machines.
2.22. If a malfunction of equipment, tools, fixtures or a workplace is detected, inform the foreman both before and during work and do not start work until the problem is resolved. It is forbidden to work on defective equipment, use faulty tools, as well as disassemble and repair electropneumatic tools on your own.
2.23. Electric welding machines should be connected to the network by means of switching devices with mechanical clamps through switches with closed type fuses.
