Building 90: Pre-Fire Plan

    Response Action:

    1. Make initial assessment of the situation.
    2. If warranted call 911 and report fire.
    3. Evacuate occupants.
    4. Report to assembly point

    There are two personnel doors on the north side facing CEBAF Center. The westward door leads to the high bay area. The eastward door leads to the upstairs office area. An internal door connects both areas.
    One ground-level door on the west side leads to room 109, which leads to the main machine shop. A double door leads to the utility room 117 which contains a hot water heater, electrical switchboard, storage, and an optic fiber console for CEBAF Center. An exterior staircase leads to a door to the upstairs office area.
    There is a roll up door and a personnel acces door on the south side, towards the Test Lab, that leads to the main machine shop.
    The east side has four roll up doors and three personnel access doors. Starting from the northwest corner, a roll up door and a personnel door lead to the high bay area. A double personnel door leads into the main passageway. A roll up door leads to the Stock Room. A personnel door and a roll up door lead to the Shipping and Receiving area. A personnel door and a roll up door lead to the RF system/DC power work area.

    There are no buildings close enough to the EEL that spread of fire could propose a problem.

    Entry into the main machine shop requires the wearing of safety glasses.

    Chemicals:A stock of less than twenty nonflammable compressed-gas cylinders are stored outside the EEL, in the parking lot at the northeast corner. Flammable gasses, such as ethnae, isobutane, and hydrogen, in compressed gas cylinders, are in use in the Physics Division area. These gases are vented into plastic, prototype detectors at low pressure. In the Material Services are (Shipping and Receiving and Property Management), hazardous materials are limited to office and commercial supplies such as requiring a Material Safety Data Sheet, such as adhesives, alcohols, cans of spray paint. All are stored in flammable storage lockers. In the Machine Shop, two flammable storage cabinets are located on the south wall and contain paint, acetone, and aerosol cans. There is only an oxy-acetylene welding rig on the shop floor. Flammable storage lockers, normally containing paints and solvents, are located in the DC power room, the Physics staging area, and the detector room.

    Lasers:There are class 4 and 3a/b lasers in room 118. There is a laser in a room within room 126. Special glasses may be required for entry into these rooms.

    Magnetic Fields:Room 124 may contain high magnetic fields.

    Radioactivity:Room 126 has a room within it that requires dosimetry for entry. Room 118 contains radioactive materials but dosimetry is not required.

    Cranes:There are overhead cranes in the high bay area and the machine shop.

    Other hazards:There is a 120 V AC electrical service throughout the building. There are welding outlets in shop areas. There is 480 V AC service to shop equipment and HVAC. There is compressed air piping in the building. Hot water at 160 to 180 degrees F in on services. The heating, air conditioning, and ventilation (HVAC) units are in the south mezzanine.

    About forty people work in the Physics Division areas. Six to eight people work in the Material Services section. About eight people work in the Machine Shop, about six work in the DC power room, about four people work in the stock room and about three people work in the laser areas. This totals between sixty to seventy people.

    This building is a Butler-style, with a corrugated steel exterior. The inside is sheet rock and steal beams. A concrete floor is covered with carpet in some office areas. Plastics and composite materials are used in clean rooms in the Physics Division area. There is a mezzanine at the south end used for storage and a second mezzanine at the north end used for offices.

    Fire Protection:
    The building is protected by a wet pipe sprinkler system. Dry power fire extinguishers are located throughout the building. There is a fire alarm system control panel in the main passageway next to the personnel door. There are alarm pull stations and alarms throughout the building. Smoke detectors are located in the passageways. The nearest fire hydrants are located in the CEBAF Center parking lot and at the southeast corner of the EEL parking lot. The PIV valve is located on the east side of the EEL.

    Loss Potential:
    Loss of the Physics Division area would be a major setback to the development of experimental equipment for the experimental halls. The valve for Hall B components alone is about $6M. Loss of the Material Services section would include loss of newly arrived equipment, irreplaceable records, and stocks of office supplies. Loss of the Machine Shop would mean the loss of up to thirty machines valued at more than $1M. Loss of the DC power room could affect long term accelerator operations. Loss of the Stock Room would mean a loss of about $2M worth of supplies and items.
