PROCEDURES TO BE FOLLOWED IN THE EVENT OF A FLOOD: I. Sinks The sinks in the lab have 3 sources of water. DI supply, DI return, and ICW. In the event of a flood, these three supply valves should be turned off. In the new lab, sink shut-off valves are found in service chases associated with each group of sinks (CG-2, CY-2, CV-2, CV-3 and CR-1). In the old lab, sink shut-off valves are located in the rear of a sink or to the right (HF sink). After shutting off these valves please use the emergency phone list to notify a staff member. II. Equipment Equipment may have several sources of water. If there is a flood associated with a piece of equipment try and find the shut-off valves. These are located in the service chases (new lab) or on the wall (old lab). The main service chase water valves are labeled "IN CASE OF FLOOD CLOSE THIS VALVE". If you have trouble locating water lines the following information may be useful: Color-codes for tubing supplying utilities such as water. 1) Orange = ICW 2) Clear = DI (1/2") 3) Black = DI Return (1/2") 4) Clear with blue tape = Recirc. supply 5) Clear with red tape = Recirc. return Shutoff valves in service chases are typically at the user level. If shutting these off fails to stop a leak, immediately call a staff member. If you fail to reach staff call OPR: ******************************************************************* Emergency Phone Numbers http://microlab.berkeley.edu/graphics/PhoneNumbers.pdf ******************************************************************* The utilities connections in the service chases of the new lab originate from lines that run overhead. There is a master shut-off valve for each utility near the ceiling, above each service chase. Access for these valves requires a ladder. One can be found in the oldlab gas storage room, 432E. After shutting off the necessary valves please contact a staff member on the emergency phone list. III. Cleaning up after a leak Use the wet-vac tank and necessary tools from 432E (gas storage room to vacuum up the water on the floor. To hook up the wet vac: a) Connect the orange flex-hose to the yellow house vacuum pipe in the upper right hand corner of the appropriate service chase. In the old lab these connections are on the cement column near the ionmill and in 432D by the gas cabinet. b) Connect the other end of the orange flex-tube to the wet-vac tank port marked "Exhaust". c) Connect the smaller black flex-hose to the other port on the wet-vac tank. d) Connect the long handled tool labeled wet-vac to the black flex-hose. e) Turn on the house vacuum system at one of the three switches. The house system provides the suction for the system. The switches are located by CY-1,CV-2 and on the column near the ionmill. The light comes on when the system is activated and it is automatically turned off every 15 minutes of use. f) While cleaning up the water, periodically check the water level in the canister. Over filling it will make it difficult to move it to the drain. It has a safety shut-off when full. f) Move the wet-vac tank to the floor drain located at the lab entrance near the shelves where the gloves are kept. Empty the wet-vac tank by opening the valve on its side allowing the water to flow out into the floor drain. g) When you have finished, replace the tools and report the incident on the wand under utilities-problems. 2/92 RH
