4. Lockout and Tagout: You Hold the Key

5. Lock Out/Tag Out Procedures 122 Deaths 60,000 Injuries Per Year Prevents

6. A preparation plant electrician was checking a Square D Type 6 Limit Switch to determine why the heavy media vessel motor had stopped operating. The victim was apparently attempting to remove/repair the limit switch,which was located on the vessel refuse chute when he received a fatal electric shock. De-energize all circuits before work is started Utilize proper frame grounding Use lockout/tagout procedures Back to Basics

7. Being an electrician,was this person aware of the danger that existed by working on an energized electrical circuit?

8. While disassembling a belt structure, workers would occasionally receive an electrical shock from the metal structure. The maintenance foreman, on his way to a mine phone to call and have all power circuits to the area de- energized, traveled along side the energized structure. Along the way, he contacted the metal frame and was electrocuted. De-energize before starting work Proper frame grounds All circuits shall include instantaneous and overload protection Lockout/Tagout Red Lights

9. The red lights were on but the foreman did not stop.

10. After a section power center had been advanced, a repairman was found electrocuted, lying over an open high voltage(7200 volt AC) splice box about 3 crosscuts outby the power center. The repairman was not a qualified person. De-energize circuits before working. Only qualified electrical persons to work on high voltage lines. Lockout/Tagout Education and Training

11. The persons selected to work on electrical circuits must be trained to safely perform this work.

12. After connecting a high pressure flexible hose to a metal air line, the 28 year old gold miner noticed the coupling was misaligned and loosened it for realignment when it came apart, allowing the hose to whip violently. Maintenance or repair should not be performed on air powered equipment until the pressure is relieved. Safety chains or other devises should be installed where a connection failure can occur. Lockout/Tagout Non-Electric

13. Do lockout/tagout procedures apply to non-electric equipment? Yes! 1. Safely release all stored energy within the system prior to performing any repairs or maintenance. 2. Lockout/tagout valves, levers, switches or any other means of activating the system to be worked on. 3. Include stored energy hazards in training sessions.

14. A 27 year old electrician and coworkers were stringing a new inactive power line along a line of poles containing energized high voltage power lines. The lines were separated by 5 feet, but the inactive line became energized, possibly through incidental contact or arcing, shocking the electrician with an estimated 40,000 volts AC. Keep inactive and active power lines a safe distance apart. Exercise extreme caution when working around high voltage lines. De-energize adjacent power. Lockout/Tagout Planning

15. Planning 1.Make sure your plan includes de-energizing, locking out and tagging out circuits that can not be a safe distance from where work is being performed. 2. Plans should also include the use of personal protective equipment: ( Rubber gloves, hard hat, eye protection and non- conductive shoes etc.) 3. Pre-visit the work area to eliminate unsafe conditions prior to starting the work. 4. Provide the person performing the work with the necessary locks, keys, tags and other lockout devises.

16. They performed the job before or witnessed someone else performing work without locking out. The disconnecting device is too far away! Not located where it is convenient for a person to use. Worker pulled disconnect but did not lock it out because they were by themselves and felt no need to lockout. They do not want to shut down system, section, plant, or operation for this minor repair. REASONS WHY PEOPLE DO NOT LOCKOUT

17. Six Basic Shutdown Steps: 1. Prepare for shutdown. Notify affected employees and tell them which equipment will be involved. 2. Shut down the machine by using normal stopping or rundown procedures for that piece of equipment. 3. Isolate the machine or equipment from all its energy sources. 4. Apply appropriate lockout/tagout devices to the machine’s or equipment’s energy-isolating devices. 5. Safely release all potentially hazardous stored energy. 6. Verify that the equipment cannot be turned on before starting service, maintenance or repairs.

18. Lockout/Tagout Procedures Apply Whenever... a. A machine or piece of equipment is repaired, serviced, lubricated, cleaned, unjammed, adjusted, or otherwise maintained. b. A guard or other safety device is removed or bypassed in order to perform work or maintenance on a machine or piece of equipment. c. An employee places any part of his or her body in contact with a point of operation where it could be caught or trapped by moving machine or equipment parts. d. An employee places any part of his or her body into a danger zone associated with the operation of a machine or piece of equipment.

19. Give permission to lockout/tagout and make the work area safe.

20. Remember... YOU HOLD THE KEY!
