1Building Hazards

1.1Industrial Hazards

Building 062 (ESB)

Building 062 contains power supplies, modulators, high-voltage power supplies, and lasers.

Several electrical power distribution systems and powered equipment devices may present arc flash hazards while operating. The PPE requirements are posted on the devices.

A white laser room contains several Class IV Lasers. Emergency entrance of the room will automatically disable the lasers.

NLCTA Accelerator Enclosure

NLCTA Accelerator Enclosure (inside ESB) contains an electron-beam source and accelerator (a prompt radiation hazard), electromagnets, laser light, and high-voltage ion (vacuum) pumps.

Emergency entrance of the room will automatically disable the electrical hazards, radiation hazards, and lasers.

All of these electrical, laser, and radiation hazards are disabled by the electrical substation shutoff buttons identified in Section 2.3.

NLCTA Experimental Enclosure

NLCTA Accelerator Enclosure (inside ESB) contains electromagnets, lasers, and high-voltage ion (vacuum) pumps.

Emergency entrance of the enclosure will automatically disable the high-power electrical hazards, radiation hazards, and lasers.

All of these electrical and radiation hazards are disabled by the electrical substation shutoff buttons identified in Section 2.3.

Buildings 128 & 129 (NLCTA Control) contains no special hazards (other than 110 VAC).

Building 485 is a light industrial shop area with powered metalworking equipment.

1.2Hazardous Materials

The klystron modulators are oil-filled equipment. The oil is white mineral oil (similar to the makeup remover available at the local drug store) which must not be allowed to spill into the storm drain systems.

  • Each of the NLCTA modulators on the south side of the building is filled with approximately 600 gallons of oil. The modulators are double-walled devices with integrated secondary containment.
  • The 8-pack modulator is filled with approximately 1500 gallons of oil. It is a single-walled device, and is surrounded by a low berm that serves as secondary containment.
  • The SNS Modulator is filled with approximately 1200 gallons of oil. It is a single-walled device closely surrounded with a low berm that is shared with the “8-pack modulator”.

Note: If water enters the modulator enclosures, the water can displace the oil which will be first captured into the secondary containment and then (once the containment is full) onto the floor.

1.3Emergency Response Kit

The oil spill prevention kit is located in the south entrance of End Station B. The kit consists of:

  • Oil absorbent materials. The spill kit is in a grey roll around bin,
  • 55-gallon barrel wet-dry vacuum cleaners

Any spill that cannot be safely contained will require emergency assistance. Assistance can be obtained from:

  • Security, extension 2551
  • Waste Management, extension 2399
  • Fire department – call 9-911.

The NLCTA areas of ESB contain cylinders of compressed, non-flammable gas.

The NLCTA areas of Building 062 (ESB) and the NLCTA accelerator is plumbed to dewars of liquid nitrogen which provide supplies of gas-phase nitrogen. There are no oxygen deficiency hazards in the high-bay part of ESB or in the accelerator enclosure (due to volumes and natural ventilation). The plastic-walled cleanrooms are equipped with air-flow interlocks that shut off the nitrogen supply in the event of a ventilation failure. With this interlock, there is no possibility of an oxygen deficient atmosphere.

A more complete call-in list for emergency situations is available from security (x2551). Ask for the NLCTA information from the Emergency Management Database.

A directory of all operators and other emergency contacts is posted on the wall of the NLCTA Control Room (Building 128) behind the copy machine.

2.2Assembly Point

The Assembly Point for this Facility is the parking lot south of End Station B (bldg. 062) near the NLCTA Control Room (bldg. 128).

3. Utility and Building Alarms System Shutoffs

There are two types of alarms in this Facility: emergency alarms (for fire), and equipment status alarms (all other alarms).

3.1 Fire Alarms

There are fire detectors and annunciators in the NLCTA Control Room (bldg. 128) and the End Station B (ESB, bldg. 062). All personnel, excepting to those directly responding to the alarm, are required by law to evacuate the building.

The modulators in the south section of the building are equipped with an automatic carbon-dioxide fire suppression system.

In the event of a false alarm (such as from soldering near a sensor point), call 9-911 immediately and inform them. Following your call, the level of the alarm will be lowered and the responders will understand that their response time is no longer critical.

3.2 Status Alarms

An equipment alarm system is installed in Rack B062-40 level 17. All alarms are annunciated in this panel. The alarm location is shown on Map 3. Additionally, the alarm system is relayed into the NLCTA Control Room and triggers an alarm at the Sector 30 guard shack. An alarm response procedure for Security is found as Appendix B at the back of this procedure.

The inputs for the alarm chassis are:

  • NLCTA Modulator Station 0 Oil Level Alarm
  • NLCTA Modulator Station 1 Oil Level Alarm
  • NLCTA Modulator Station 2 Oil Level Alarm
  • Kicker Oil Level Alarm (located inside Accelerator Enclosure)
  • 8-Pack Oil Level Alarm (located under 8-Pack floor)

Appendix A – Water system shutoff locations

Refer to Map 2.

8-Pack Water

  • Most sub-components have local shut-off valves which should be used if possible.
  • The shut-off valves for each klystron is located immediately below the aluminum floorplate panel.
  • The shut-off valves for the modulator is immediately below the aluminum floorplate panel to the south of the modulator behind the klystron nearest to the modulator.
  • The shut-off valves for the SLED-II piping systems are located next to the to the LCT Control Panel on the north wall of the NLCTA Accelerator Enclosure.
  • Water supply can be shut off using the manual valve near the pressure regulator station near the 8-Pack on the north side of the NLCTA accelerator enclosure. Note: this only shuts off the supply line regulator which reduces system pressures from 200 psi to 135 psi. Since the return line pressure is 30 psi, water flow from a leak will be reduced but not stopped.

Appendix B – Alarms Response Procedure for Sector 30 Security Binder

End Station B (building 62) Alarm Response

The klystron modulators in the End Station B contain a large oil tank which can overflow due to a water leak and spill large amounts of oil onto the floor and leading out the building. This is mineral oil used for cosmetics, but any spillage into the storm drain system is considered a release of a toxic compound and must be stopped if at all possible.

Alarm Response

Depending on the nature of the spill, the alarm is expected to provide between 1/2 hour and a day notice prior to a potentially hazardous situation.

  • Call the NLCTA Control Room (x5482) to determine if assistance is required. If the control room is not occupied, then proceed to the end station.
  • Immediately across from the fire panel on the south wall of the end station is the annunciator panel. The alarming channel can be identified by looking on the front panel of this module.
  • Go down to End Station B and examine modulator systems.
  • Examine modulators for evidence of and oil or water leak (which may not be immediately visible).
  • Go into the control room (Building 128) just outside the End Station B and find the emergency response call-down list on the North side wall of the control room.
  • Call personnel on the board in the order listed.
  • If you are unable to contact any of the emergency response persons listed on the board, call MainControlCenter (2151) and explain the situation to the operator. They will be able to dispatch maintenance mechanics to turn off all water sources for the accelerator systems in the area.
