34. 6/7/201634 Material Handling in Shafts Only authorized personnel are allowed to operate shaft cranes. Do not utilize the below ground shaft area for storage. All personnel must keep clear of the bottom of shafts at all times.

35. 6/7/201635 Air Quality Potential Points of exposure. –Build up of cutting and welding smoke. –Chemical spills. –Compressed gases. Plan for protection in the Hazard Analysis. –All compressed gases and chemicals must be approved by the SSO before going underground. –Monitoring the air, if necessary. –Increase airflow with portable fans. –Use portable air filters to eliminate smoke. –Personal respirator, if necessary.

36. 6/7/201636 Fire Housekeeping is a priority. –Keep walkways clear and fire doors closed. Keep fire loading under control. –Only approved flammables and combustibles allowed underground. Debris and trash must be removed daily.

37. 6/7/201637 The Near Detector will have a magnetic field when the coil is energized. When the coil is energized all employees in the area will be notified by signage and a blinking red light. People with pacemakers must stay out of the delineated (red line) area. Magnetic Field

41. 6/7/201641 MI-65 –During Maintenance/Installation – 50 Personnel Carrier Tunnel – 4 Personnel –During Normal Operations – 8 Personnel MINOS –During All Operations – 50 Personnel Note: The twelve stories of stairs in the MI-65 shaft may be the only exit from the underground. Occupancy Requirements

42. 6/7/201642 In the MI-65 and MINOS underground –Hardhats at all times due to the danger of falling pieces of shotcrete. –Shoes that are completely closed and low heeled. –Carry a flashlight at all times. Additional PPE may be required for specific work or inspection activities. –Check Hazard Analysis. PPE/Work Clothing Requirements

43. 6/7/201643 Access Control Procedures Key access is required. The “two person rule” applies to entry and occupancy in underground areas. –Essentially, we do not want anyone working (physical work) alone underground. An individual can enter or leave by themselves when there are other persons underground in their areas. Entrants must check in at the entry control panel. –Remove an entry pass card, place your Fermi ID on the panel, keep the entry pass with you while underground, upon leaving take your Fermi ID and replace it with entry pass card.

44. 6/7/201644 Additional Required Training Entering interlock areas ( Target Hall, Pre- Target, Carrier Tunnel, Muon Alcoves, Absorber Hall, and Decay Pipe Walkway ) Controlled Access Rad Worker LOTO 2 (Only for access to Pre-Target, Target Hall, and the Carrier Tunnel) All other areas ( MI-65 and MINOS Service Building, Absorber Access Tunnel, Near Detector Hall, and Target Hall Support Rooms ) GERT Rad Worker (Target Hall Mechanical Support Room Only)

45. 6/7/201645 Access To MI-65 The service building requires an AC 4 key Elevator access key is checked out and returned through the Main Control Room. One access key per person. Interlock enclosure ( Target Hall, Pre-Target, Carrier Tunnel, and Decay Pipe Walkway ) access key is located in the Main Control Room Place LOTO lock on MI-65 group lock box in MCR for 13.8 Kv transformer prior to entering the interlock enclosure

46. 6/7/201646 Access To MINOS The service building requires key #A5BB19 Elevator access key is checked out and returned through MINOS Control Room located on the 12 th floor Wilson Hall NW. One access key per person. Interlocked Areas ( Absorber Hall, Muon Alcoves, and Decay Pipe Walkway ) access key is located in the Main Control Room.

47. 6/7/201647 Untrained Personnel Access Untrained personnel and their escorts accessing the underground must be approved by the Division SSO or designee Limited to two people per escort The escorted must receive training –Review and sign the Site Safety Briefing –Receive field training on self rescuer Untrained personnel must be escorted 100% of the time

48. 6/7/201648 Elevator Usage Underground access is provided by elevators in MI-65 & MINOS shafts. There is a fireman’s elevator next to the access elevator in the MINOS shaft. It is used by the fire department in the event of an emergency. Close both the interior & exterior doors upon entering and exiting the elevator Press green button to go up or down Lab Phone Elevator Operation Buttons Fireman’s Phone

49. 6/7/201649 Elevator Usage If elevator becomes disabled while in transit call 3131, using the telephone in elevator A descent device is located on the ceiling. Instructions are posted. Do not use unless instructed by the Fire Department

50. 6/7/201650 Laboratory telephones are located throughout both the MI-65 & MINOS underground areas. Emergency generators operate within 20 seconds after permanent power shuts down(elevators, every third light, shaft cranes and passageway ventilation will be powered). Underground Utilities

51. 6/7/201651 When first entering the underground you should become familiar with: –All emergency walkways and exits in your area. –Location of telephones. –Location of self rescuers. Self rescuers will be stored in marked containers in both shaft areas. –Location of fire extinguishers. Mounted on walls near the shafts. Emergency Management

52. 6/7/201652 Types of emergency situations and potential emergency situations –Fire/Explosion –Smoke –Cryogenic System Failure –Loss of permanent power –Loss of ventilation system, lighting, elevator or fire detection Emergency Management

53. ODH Alarm 6/7/201653 The Near Detector is a zero ODH area. The cryogenic system associated with MINERvA is self contained and cannot escape into the Hall. However, if there is a leak within the system, the ODH alarm will sound and everyone is required to evacuate.

54. 6/7/201654 If you have to call an emergency in due to an injury or any other emergency where the alarms have not sounded, immediately call 3131. –Give your name. –Give your location(state you are underground). –Give the nature of the emergency. Verify all the information is understood. Evacuate immediately if necessary. Emergency Management

55. 6/7/201655 Emergency Management MI- 65 Site –Primary emergency egress is the stairwell. –Secondary emergency egress is the elevator. MINOS Site –Primary emergency egress is the access elevator. –Secondary is the MI-65 elevator or emergency stairwell.

56. 6/7/201656 Emergency evacuation of underground. –Upon hearing fire alarms or other notification declaring an emergency, immediately go to the shaft area and evacuate. –Utilize the emergency passageways during evacuation to shaft (Equipped with independent positive pressure ventilation system). After evacuating to surface report to the service building parking lot and check in with your supervisor or Fire Department. Emergency Management

57. 6/7/201657 Emergency Management Alternate means of emergency egress –MI-65 If the stairwell and elevator are blocked, take the Decay Pipe Walkway to the MINOS shaft. If the stairwell, elevator and Decay Pipe Walkway are inaccessible then proceed through the Carrier Tunnel to the Main Injector –MINOS If the elevators are inaccessible, then proceed through the Decay Pipe Walkway to the MI-65 shaft, continue to the Main Injector if necessary. –Always notify the Fire Department (call 3131) before proceeding in the Decay Pipe Walkway

58. 6/7/201658 Tornado Emergency Personnel located underground shall remain underground, as directed, during the emergency Personnel in the MI-65 or MINOS Service Buildings shall proceed to the Tornado Shelter –The MI-65 shelter is the interior hallway between the electrical and fire protection rooms –The MINOS shelter is the small interior mechanical room located on the north end of the service building

59. 6/7/201659 OCENCO M-20 SCSR –Is a compressed oxygen, self-contained self- rescuer (SCSR). –It will instantly provide breathable air independent of the surrounding atmosphere when donned correctly. –To be used for escape use only and lasts 15 to 20 minutes. –You must take the Ocenco M-20 SCSR with you whenever you enter the Decay Pipe Walkway. Self Rescuer

60. 6/7/201660 When a fire or explosion creates excessive smoke or carbon monoxide. Whenever you have difficulty breathing due to air contaminants. When Self Rescuer is Used Note: Self rescuers are stored in marked containers next at the bottom of the MI-65 and MINOS shafts. Additional rescuers are located at the fire door leading to the Absorber Hall.
