COMPARATIVE MEDICINE LABORATORY ANIMAL FACILITIES

1. Purpose
   This procedure states the need for ear protection when entering or working in the dog rooms.
2. Scope
   This procedure applies to all animal care and authorized visitors in applicable areas.
3. Procedure
   1. It is recommended that ear protection be used when entering or working in rooms housing dogs.
      1. The use of ear muffs or ear plugs is required for employees assigned to work in the dog rooms.
      2. The use of disposable ear plugs is recommended for authorized visitors entering the dog rooms or other noisy areas in the animal care facilities.
      3. Ear plugs can be obtained from the facility manager or the floor and area supervisors, or in room 315 in labeled drawer.
      4. Ear muffs are located in room 315 inside labeled drawer.
   2. The exposure to noise is dependent upon the time spent in the rooms and the number and activity of the dogs.
      1. Most commonly high sound levels occur only during the first few seconds upon entering a room.
      2. Other factors to consider are that different people have different levels of sensitivity to noise, and that the relatively high-impact noise of dogs barking, even if not continuous, can be irritating over a period of time.
