3. Safe Rigging Principles And Requirements - 00059147- Rev.4 Safety Training Training and Development Attachment 3, Industry Events, (as applicable) Bulletin Number 05-03 October 21, 2004 Subject: Serious Rigging Accident at TVA Nuclear Plant Recently, a partner ironworker working at Sequoyah Nuclear Plant was seriously injured while installing bollards for a security upgrade project. The injury occurred when a 1000 pound bollard was being lifted into place. As it was positioned over a trench, the rigging system failed causing the bollard to fall several feet striking the employee. He sustained a serious leg injury as a result (Obj.1). The employee required surgery and is recovering at a local hospital. The accident is under investigation. Since many jobs in COO involve rigging it is important that we identify rigging hazards and pre-plan safe work practices into all lifts. In this case, a non-standard method was used by attaching rigging to 4X6X8 inch cribbing to lift the bollard into place. Additionally, the injured employee was positioned under the load. TVA Safety Procedure (TSP) 721, “Rigging” establishes requirements that must be adhered to when planning and executing any rigging and lifting. Following is a summary of requirements from TSP 721. 1. All rigging hardware must be inspected by a qualified rigger prior to use and as necessary during its use. 2. All rigging must be inspected at least annually and color coded to identify that the yearly inspection has been done. Rigging must be inspected for damage by the user also prior to lifting. 3. Only rigging hardware and equipment purchased or fabricated under TVA specifications will be used for rigging of a load. 4. If a load requires some unique rigging the crane coordinator and a qualified engineer will be consulted prior to its use. 5. An accurate determination of the load weight must be made before each lift. 6. Rigging will consider the attachment point on the load and the structural integrity of the load itself. If there is anything unknown as to how much the attachment point can bear, an engineering analysis must be performed prior to making the lift. TVA Safety Procedure 802, “Requirements for the Safe Operation of Cranes”, establishes the following requirement. As a general rule, lifting loads over personnel is prohibited. However, in situations where it is impossible to perform the lift without lifting over personnel, such lifts will be deemed high hazard, thus requiring formal planning. Such planning situations may include rearranging of the job site or rescheduling so as to make the lift without endangering personnel. Special attention will be given to personnel who may be under the floor or surface where the load is to be set or where the load could fall through the floor or roof. The structural capacity of the surface where the load is to be placed will be determined if the failure could endanger personnel or equipment located under the load-bearing surface. The rigging plan and method of lifting must be discussed in full with the entire crew involved with the job prior to any work commencing during the pre job brief. Page3of variable

4. Safe Rigging Principles And Requirements - 00059147- Rev.4 Safety Training Training and Development Attachment 3, Industry Events, (as applicable) Bulletin Number 05-28 May 04, 2005 Safety Awareness Bulletin Subject: Rigging Incidents This safety awareness bulletin provides a summary of several recent incidents at TVA facilities that require our attention to safety when rigging and handling material. Recently, Power Service Shop employees at Browns Ferry were tightening bolts on the Unit 1 Combined Intercept Valve. One person was using an impact wrench to secure the bolts and could not get the tool onto a particular bolt due to the location of the valve linkage. The employee was using a nylon choker to attempt to lift the valve arm to provide additional clearance. At one stage while lifting the valve arm an employee placed his hand between the linkage and the impact wrench. The choker broke and the linkage fell pinching the employee’s hand. ( Obj.1) The injured employee was treated at a local hospital and released. Later another choker was used to lift the linkage to remove the impact wrench. In this incident, the exact weight of the object being lifted was not known to the employees involved. On the same day at Browns Ferry, employees were using a nylon choker to move several steel chokers to a storage area. The steel chokers became caught on plant equipment which caused damage to the nylon choker. Fortunately, an observer noticed the pulling nylon choker and notified the flagman who stopped the lift. The next day, Power Service Shops employees at Sequoyah found two nylon slings that were defective. These slings had been used for turbine lifts. One of the slings had a “tell-tale” missing. A ‘tell-tale” is a white and red indicator line on each side of the choker that is used to indicate that the sling had exceeded its capacity. The other sling had a significant abrasion to the outside cover. Both of the damaged slings were taken out of service. Recommendations: 1. Ensure that slings have been properly inspected before use. See TVA Safety Procedure 721, “Rigging”. 2. Do not use slings that are damaged or defective. 3. Know the weight of objects to be lifted. Do not load slings in excess of their rated capacities. 4. Slings used in a basket hitch must have the load balanced to prevent slippage. 5. Securely attach slings to their loads. 6. Slings will be padded or protected from the sharp edges of their loads. 7. Suspended loads will be kept clear of obstructions. 8. Keep clear of loads to be lifted and suspended. 9. Do not place hands and fingers between the sling and its load while the sling is being tightened around the load. 10. Do not pull slings from under a load when the load is resting on the sling. 11. Store slings in an area where they will not be subject to damage. Page4of variable

Safe Rigging Principles And Requirements - 00059147- Rev.4 Safety Training Training and Development Attachment 3, Industry Events, (as applicable) PROJECT NAME: _TVA KIF Scrubber___ CONTRACT NUMBER: _____________ LOCATION OF PROJECT: _Harriman, Tn.__________________________________ PROJECT MANAGER: __Gary Ruzicka ___ PHONE NUMBER:_(865)717-4501____ LOCAL TIME/DATE OF INCIDENT: 07/14/08 ; 4:45 pm DESCRIPTION OF INCIDENT: On 7-14-08 at approximately 4:45 PM five ironworkers were in the process of setting a beam. During the process they noticed it was too late in the day to weld the beam in place. Foremen and crew decided to secure the beam with two 1 ton chain falls from the iron above (weigh of beam approx. 1500 lbs.) While one end of the beam was secure ironworker Jeff York positioned a ladder into place to climb up and secure the beam with a safety strap at the location of the second chain fall. He set the ladder and was going up the ladder with his left arm on one of the rungs. At this moment there was a loud bang and three ironworkers were knocked to the ground including Jeff York. The loud bang came from one side of the beam falling from the rigging it was hooked to (approx. 8’ over head). Two of the ironworker got up and heard Jeff York say help me up I have broken my arm. The beam had fell landing on Jeff York’s lower left arm then knocking him to the ground. He was then taken to ground level where he was transported to Oak Ridge Medical Center. CONDITION OF EMPLOYEE: _Broken lower left arm_(Obj.1) PRINCIPLE CAUSE OF INCIDENT : Improper rigging CORRECTIVE ACTION/LESSONS LEARNED: Refresher training with NSC is in progress, refresher training with all other subcontractors will be completed within 30 days. Survey of chain fall use throughout site boundaries is in progress and on going. Develop "at risk" employee program as well as visual identifier for "at risk" employees within 60 days. NSC terminated three of the iron workers involved in this incident due to violation of safety procedures. Advatech CM staff representative will be attending TVA train the trainer course on TSP 721A Rigging Procedures. Lessons Learned: Craft skill competency is not at the level expected. Our action plans will help address this issue. Page5of variable
