by having a double bench with a service strip down the middle. T h e benches serve as the lower half of the wall. A dividing curtain wall is suspended from the ceiling and rests on the middle of the bench. This cuts down service lines for two laboratories from six to four. Hoods can be located almost a n y where in the room. I n one case the wall bench closest to the en trance door was selected to mini mize length of duct runs and to enable one person to observe both hoods, which is desirable from a safety viewpoint. If the air duct to the room is located above the hood, a grille is used to direct the air away from the face of the hood. Although safety showers are often located at the exit door, there is a trend toward locating them in the corridor. A fire extinguisher may be located opposite the hoods. All laboratories need a safety exitto permit egress from either extreme of the laboratory. There are m a n y arguments as to whether chemists should be pro vided with a laboratory office. The author believes such to be desirable as being good for morale, providing some privacy which is conducive to reading and writing, and in im proving efficiency. If the office is located in the laboratory proper, the worker can keep an eye on work going on in the laboratory while he is in his office. Doors for laboratory offices are not desirable. Special Facilities. There is a de veloping trend toward specific types of facilities for calculations and record storage. Where needs for calculations pass the portable cal culator stage, a small sound proof centrally-located room m a y be desirable. If an I B M setup is used in the bookkeeping center, ar rangements m a y be made to use this equipment. Record storage facilities to keep valuable notes, such as those needed in supporting p a t e n t applications, should be considered in planning a laboratory. T h e room should be fire-proof and have temperature and humidity controls. This func tion m a y be allocated to the library staff. This chapter sets forth five pages of typical floor plans used in chemi cal laboratories.
