Description: When using fuel gas welding and cutting, safety is an integral part of any operation. Program explains cylinder connections, valves, cracking, and basic safety procedures when using fuel gas welding and cutting. Excerpt: When you're working with gas welding, and cutting operations there are a number of safety procedures to follow. Each company is responsible for developing specific guidelines, policies, and procedures as a short video training program cannot list all the potential hazards or safety elements. This program is simply a guideline of basic safety measures designed as safety awareness, but it's not a complete or comprehensive program. Let's begin with the area used for such operations. The welding or cutting area must be protected against fire hazards posed by combustible and flammable materials. Combustibles must be located at least 35 feet from the worksite. If this is not possible combustibles must be protected with flame proof covers, or metal, or other fireproof shielding. Floors on which combustible materials such as paper clippings, wood shavings, or textile fibers accumulate must be swept clean for a radius of 35 feet. Keep in mind that welding temperatures are extremely high and welding on metal can create heat transfer from the metal part to combustible materials located nearby. Welding operations have caused a high number of major fires. Due to the potential for fires, explosions, and health hazards, cutting or welding must be carefully controlled. Never weld or cut in the presence of mixtures of flammable gases, vapors, liquids, or dusts with air, or inside improperly cleaned tanks or equipment which had previously contained such material. Never weld or cut near large quantities of exposed, readily ignitable material, such as bulk sulfur, baled paper, or cotton. Never weld or cut near vapor degreasing operations, or spray booths due to the potential fire hazards. Some chemicals can decompose under the ultraviolet radiation of the welding or cutting operation and become quite dangerous. Always weld and cut in those areas authorized by management. Protection in the form of curtain or enclosures is required when other persons could be harmed by the effects of the flying slag, or eye hazards. Most gas welding and cutting operations use compressed gas cylinders and there are important procedures to follow when using these gas cylinders. All cylinders stored inside must be located in a well-protected, well-ventilated dry location. They must be at least 20 feet from highly combustible materials, sparks, open flames, excessive heat, and away from elevators, stairs, or gangways. When cylinders are not connected for use valve protection caps must be in place unless the cylinder is not designed to accept the cap. Stored oxygen cylinders must be separated from stored fuel cylinders or combustible materials, especially oil or grease by at least 20 feet, or by a non-combustible barrier. This barrier must be at least 5 feet high and have a fire resistance rating of one half hour. All cylinders must be legibly marked to identify their contents. Cylinders connected for use must be latched or chained to prevent them from falling over. Be careful that cylinders are not placed so as to become part of an electrical circuit. Mark empty tanks MT, close the valves, and replace valve caps securely. Let's take a look at the valve and regulator settings. The regulator is a delicate piece of equipment, and must be carefully handled at all times. Pipe wrenches or pliers must not be used for attaching regulators to cylinders. Use an end-wrench of proper size. Leave the valve wrench on the acetylene cylinder whenever the valves are open. This permits emergency shut off of the gas. Hammers or wrenches must not be used to open or close cylinder valves that are fitted with hand wheels. If a regulator creeps have it repaired immediately. Creeping of a regulator is indicated by a gradual increase in pressure after the torch valves are closed. Hoses showing leaks, burns, or worn places must be replaced or repaired. Hoses should be color-coded to avoid accidental mixing of the gases. You can see in this graphic the green hose is for oxygen, and it has a right hand thread. The red hose is acetylene.
