Unformatted text preview: incident. Below are some ways to eliminate these risk factors. Ask for assistance when you are assigned tasks that cannot be safely completed alone. The task assigned to the victim could not have been done safely by only one person. Do not work overtime performing hazardous tasks that are not part of your normal assignments. Employees should only be given tasks that they are qualified to perform. All employees below the journeyman level should be supervised. Planning with others is especially helpful. It allows you to coordinate your work and take advantage of what others know about identifying and controlling hazards. The following is a list of some things to think about as you plan. Work with a "buddy"--Do not work alone. Both of you should be trained in CPR. Both of you must know what to do in an emergency. Know how to shut off and de-energize circuits--You must find where circuit breakers, fuses, and switches are located. Then, the circuits that you will be working on (even low-voltage circuits) MUST BE TURNED OFF! Test the circuits before beginning work to make sure they are completely de-energized. Don't work alone. Test circuits to make sure they are de-energized. Section 8 Page 59 S A F E T Y M O D E L S TAG E 3 -- C O N T r O L L I N G H A Z A r D S : S A F E W O r K P r AC T I C E S Plan to lock out and tag out circuits and equipment--Make certain all energy sources are locked out and tagged out before performing any work on an electrical circuit or electrical device. Working on energized ("hot") circuits is one of the most dangerous things any worker could do. If someone turns on a circuit without warning, you can be shocked, burned, or electrocuted. The unexpected starting of electrical equipment can cause severe injury or death. Before ANY work is done on a circuit, shut off the circuit, lock out and tag out the circuit at the distribution panel, then test the circuit to make sure it is de-energized. Before ANY equipment inspections or repairs--even on socalled low-voltage circuits--the current must be turned off at the switch box, and the switch must be padlocked in the OFF position. At the same time, the equipment must be securely tagged to warn everyone that work is being performed. Again, test circuits and equipment to ensure they are de-energized. This worker is applying a group lock-out device. The equipment cannot be re-started until all workers remove their locks. No two locks should be alike. Each key should fit only one lock, and only one key should be issued to each worker. If more than one worker is working on a circuit or repairing a piece of equipment, each worker should lock out the switch with his or her own lock and never permit anyone else to remove it. At all times, you must be certain that you are not exposing other workers to danger. Workers who perform lock-out/tag-out must be trained and authorized to repair and maintain electrical equipment. A locked-out switch or feeder panel prevents others from turning on a circuit. The tag informs other workers of your action. Remove jewelry and metal objects--Remove jewelry and other metal objects or apparel from your body before beginning work. These things can cause burns if worn near high currents and can get caught as you work. Plan to avoid falls--Injuries can result from falling off scaffolding or ladders. Other workers may also be injured from equipment and debris falling from scaffolding and ladders. Page 60 Section 8 A worker was attempting to correct an electrical problem involving two non-operational lamps. He examined the circuit in the area where he thought the problem was located. He had not shut off the power at the circuit breaker panel and did not test the wires to see if they were live. He was electrocuted when he grabbed the two live wires with his left hand. He collapsed to the floor and was found dead. Employers should not allow work to be done on electrical circuits unless an effective lock-out/tag-out program is in place. No work should be done on energized electrical circuits. Circuits must be shut off, locked out, and tagged out. Even then, you must test the circuit before beginning work to confirm that it is de-energized ("dead"). 277 VOLT LAMPS FUSE BOX Section 8 Page 61 Ladder Safety Fact Sheet
To prevent injury when climbing, follow these procedures: 1. Position the ladder at a safe angle to prevent slipping. The horizontal distance from the base of the ladder to the structure should be one-quarter the length of the ladder to its resting position. 2. Make sure the base of the ladder has firm support and the ground or floor is level. Be very careful when placing a ladder on wet, icy, or otherwise slippery surfaces. Special blocking may be needed to prevent slipping in these cases. 3. Follow the manufacturer's recommendations for proper use. 4. Check the condition of the ladder before using it. Joints must be tight to prevent wobbling or leaning. Page 62 Section 8 5. When using a stepladder, make sure it is level and fully open. Always lock...
