334 HUMANE TREATMENT OF ANIMALS USED IN RESEARCH 
Animal quarters at the Memorial Hospital of Long Beach (Calif.) are in a well-lighted 
room, with cages elevated for ease in cleaning and in feedings the animals. 
The animal facility planned for the Halper Clinic Building of the Mt. Sinai 
Hospital Los Angeles (see fig. 2) illustrates important design considerations in 
a larger urban facility. 12 The clinic building is a new six-story structure with 
the top three floors to be devoted exclusively to research. The animal facility 
is on the sixth floor, occupying approximately 3,000 square feet, which is approx- 
imately 20 percent of the total research space in the building. 
The animal housing area is physically separated from the laboratory areas 
by its top floor location and by a double-door entry vestibule from the research 
space on the same floor. The facility is separately ventilated and air con- 
ditioned. 
The surgery unit is located adjacent to the animal housing area, with direct 
access across a corridor to the room housing postsurgical dogs. A shower-locker 
room is provided for animal technicians and research workers. 
FLEXIBLE FACILITIES PROVIDED 
The facility provides flexibility in that rooms are provided for both large and 
small animals. The research programs may require the use of calves, goats, 
and sheep. Accordingly, pens are provided in an all-purpose room. Most of 
the time these pens will serve for isolating and conditioning newly received dogs, 
prior to their transfer to the main dog-housing area. The pens in the largest 
animal room will provide out-of-cage exercise areas or permanent housing for 
compatible groups of dogs. A small treatment area is provided for medicating 
animals. 
Facilities in the cage-cleaning room include a washing machine for small 
animal cages and a steam booth for racks and equipment too large for the 
machine. The three-compartment sink will serve for cleaning water bottles 
and as a soaking vat, and will be used for bathing and dipping newly received 
dogs. 
The necropsy laboratory within the animal facility eliminates the need to 
transport animals to distant laboratories for necropsy. Not shown in figure 2 
is a crematory and incinerator for animal carcasses and soiled bedding. This 
facility is located on the roof, directly accessible via the service elevator. 
Only a small food-preparation corner has been planned, since commercially 
available rations will be used primarily. The main dry food storage room is 
located adjacent to the service elevator. Daily food supplies will be kept in 
closed containers in the animal rooms. 
The service elevator will be used only for delivery of supplies and animal 
transport to the research floors below. It will not be accessible to the general 
public.

Angeles, authorized the description of the hospital’s animal facilities.
