Abstract

A survey was conducted of 46 laboratory animal rooms (33 rat rooms, 8 mouse rooms, 2 rabbit rooms, 2 primate rooms, and 1 dog room) at 3 commercial use sites, 5 universities, and 1 research organization. Air exchange rates, air velocities, temperatures, humidities, ammonia concentrations, noise levels, and light levels were measured throughout the room and within selected cages in the room. Cage conditions varied widely among cages within the same room and among similar cages in different rooms. Cage type was the most important factor that influenced cage conditions and uniformity in cage conditions. Room air exchange rate had little influence on cage conditions. Velocity approaching the cage, number of returns and diffusers, and diffuser type did not significantly influence cage conditions and uniformity in cage conditions.
