accidentally. If possible, unplug or disconnect it. If the machine is permanently installed with a control <br />box, turn off the switch, shut the box and put a "DO NOT TOUCH" sign on it with your name. <br />When you have finished working on it, replace all protective and safety devices and make sure they <br />function correctly. <br />j.) SAFETY PRACTICES FOR MECHANICS AND SHOPS. <br />1. Loose clothing, shirttails outside pants, rings, chains, or thick bracelets cannot be used near <br />machinery or equipment that has moving parts. Shirt sleeves must be correctly buttoned. <br />2. Do not use the mobile phones or radios while performing a task. Complete the call prior to <br />commencing the task. <br />3. Keep fingers away from all moving parts. Always turn off the power source of all machinery <br />or equipment before checking it or beginning repairs. Inspect your equipment at least once a <br />day, before starting it up. <br />4. Whenever possible, use clamps or bench vises to secure the piece you are working on. Many <br />machines have blocking devices, as for example, lawnmowers. Make sure these devices are in <br />working order and NEVER remove them. <br />5. When working with hydraulic systems, avoid getting under such equipment. Always use <br />mechanical blocking devices to prevent the equipment or part from falling on top of you if the <br />system is defective. <br />6. Always know the location of the nearest fire extinguisher. Plan out how you will react in case <br />of a fire or other emergency. Keep your work area clean and remove all waste. Keep deposits <br />of combustible materials as far away as possible from areas where flames, sparks or electrical <br />fires might occur. Keep these storage areas clear of waste and other inflammable materials. <br />Make sure passageways and aisles are not obstructed. <br />7. Make sure fire extinguishers are easily accessible. Learn how to use them and check them <br />frequently. Report if you have had to use a fire extinguisher or if any extinguisher needs <br />recharging. A fire extinguisher must be no more than 25 feet away from welding equipment or <br />an open flame. <br />8. Hoses and cords of welding equipment must be wound up, and if they are in use they are to be <br />positioned so that they do not obstruct the traffic flow of employees along aisles. Gas cylinders <br />must be stacked vertically and correctly chained to their carts. Gas regulators must be <br />protected from blows. Check your welding equipment at least once a day, before using it. <br />9. Avoid breathing in fumes and vapors generated by welding equipment. Many of these fumes <br />are toxic, some having an immediate effect while others accumulate. <br />10. The welder is responsible for clearing his surroundings of substances that could ignite during <br />welding. <br />11. The welder must use personal protection equipment (PPE) to protect his eyes, face, hands and <br />arms, all in accordance with current regulations. When doing electric arc welding, consider the <br />safety of co-workers who might be in the vicinity and use the necessary materials or <br />implements for protection and insulation. <br />12. If you have to climb a ladder to do welding work, never use a metal ladder. The ladder must be <br />of a non -conducting material. Remember that any work done at a height of more than 6 feet <br />requires the use of safety devices, such as harnesses and ropes, etc., and you must have been <br />trained to use them. <br />13. Oxygen is explosive when it comes in contact with grease and oil. Keep all parts of welding <br />equipment, such as regulators, hoses and torches clear of oil and grease. Your hands must also <br />
