- Make initial assessment of the situation.
- If warranted call 911 and report fire.
- Evacuate any occupants.
- Report to muster point.
There is only one access door for each buildings 91 and 95; both doors are on the east side.
Buildings 91 and 95 are sufficiently distant from other buildings that the spread of fire is highly improbable.
There are two water pumps and one air compressor normally present in each building. High pressure nitrogen and hydrogen bottles are in service at the outer side of the shield wall. Mixed bed resin bottles are present which are an explosive hazard if allowed to dry. Low conductivity water (LCW) is chemically inert, but is a strong gamma radiation sourse while the beam dumps are operating. Within two minutes or ceasing the operation of the dumps, the gamma radiation will be reduced to a level that is low enough to permit entry. Within one half hour the gamma source will have completely dissipated. The water will contain low levels of tritium and other radio nuclides which should be controlled to prevent unnecessary exposure or release to the environment. Resin bottles are shielded and will be a sourse of gamma radiation if the lead shielding is disturbed.
Buildings 91 and 95 are not normally occupied.
Both buildings have two-foot-thick, reinforced concrete walls and floors; the roofs are flat.
Automatic fire detection consists of heat detectors, manual pull stations, and alarm bell in each building. Fire alarm systems are centrally annunciated in building 85 (MCC) and the gate house.
Loss of buildings 91 and 95 would result, respectively, in complete loss of the cooling system for Hall A beam dump and Hall C beam dump. This could damage the dumps and would severely restrict beam power allowed into the affected hall.
