Loading and unloading areas need to be considered when designing animal entrances and exits. If it is necessary to raise large animals, the loading and unloading area is a very important place, and it is also one of the important symbols of whether an animal laboratory is designed or not. Designers need to fully understand the characteristics of the research objects of the animal laboratory, and through appropriate design of space, fences, doors, floors, aisles, special organs, etc., animals can enter the facility smoothly and reduce animal resistance behavior and anxiety Emotional and physical harm, while also facilitating pollution control, factors designers need to consider include:
1. Personnel entrances are usually combined with showers and changing rooms. If the facility is large, it is best to set up separate entrances for men and women to reduce waiting time.
2. Animal entrances and exits are generally considered to be designed as double doors, buffer rooms or air locks. For biosafety level, three and four animal facilities, it is mandatory to have a buffer room at the entrance and exit of the animal keeping room. Double doors, buffer rooms or air locks can play a key role in reducing air exchange, reducing noise, preventing animal escape and wild animals from entering, etc. Designing the entrance and exit of the facility with positive pressure can help prevent environmental hazards from entering the facility.
3. The channel refers to the transfer window, aqueduct and transmission pipeline, etc., and the double-leaf pressure cooker can also play the function of the channel. These passages have the functions of "shortcut" and avoiding opening and closing doors. It is necessary to select transfer windows, aqueducts, transfer pipes and double-leaf pressure cookers with appropriate functions and sizes according to work requirements and pollution control requirements.
