d. all of the above
For safety, which way should doors open?
Into animal rooms - if it is necessary that they open toward a corridor there should be a recessed vestibule
Constant-volume HVAC systems have been most commonly used in animal facilities, but variable-volume (VAV) systems may offer design and operational advantages. What is the advantage described in the Guide?
VAV systems allow for ventilation rates to be set in accordance with heat load and other variables
Valves controlling reheat coils should fail in what position…open or closed? Why?
Closed - if they failed in the open position the air would continue to be heated and increase the risk of heat stressing the animals in the room
Steam coils should be avoided or equipped with what system to prevent space overheating and animal loss with valve failure?
High-temperature cut-off system
Light fixtures, timers, switches and outlets should be properly sealed to prevent what?
Vermin access
T/F: Corridors may be used as storage areas in certain instances.
False - corridors are not appropriate storage areas
With respect to surgical facilities, ventilation systems supplying filtered air should supply air at relatively positive or negative pressure?
Positive pressure

d. contains exotic agents that pose high individual risk of life-threatening disease and for which there is no available vaccine or treatment
a. contains agents not known to cause human infection
Which of the following best describes ABSL-4?
a. contains agents not known to cause human infection
b. contains agents of moderate risk that cause human disease by ingestion, percutaneous, or mucosal exposure
c. contains agents that cause serious and potentially lethal infections and have known potential for aerosol transmission
