Research Units 
A typical research unit in the main 
laboratory is 50 by 40 feet. It is com- 
pletely self-contained to prevent cross- 
contamination. (See typical unit, main 
laboratory, below.) Within the unit, live 
steam, hot water, gas, fuel oil, and elec- 
tricity are available. Filtered air is 
brought in at the temperature and hu- 
midity needed for research. 
Entrances and exits to the unit are 
separate dressing room-shower-dressing 
room arrangements for men and women. 
Supplies and animals are brought in 
through the air-lock doors. 
Each unit has a general service area, 
surrounded by three basic research 
rooms, a walk-in refrigerator and in- 
cubator room, a gaseous sterilizer, and a 
record room. Animals used in current
