　　1) Issue

　　1. The electrical load of the production area (animal experiment area) of the barrier environment facility should be level 2 or higher. Or prepare a backup power supply.

　　2, barrier environment facilities should install special power distribution cabinets in auxiliary areas.

　　3. The power distribution equipment in the barrier environment facility purification zone will be a concealed facility to prevent dust accumulation, the wire ducts will be hidden, and the nozzles of the wire ducts inside the equipment will be firmly sealed.

　　4. The water pipes in the laboratory animal facilities should be metal pipes, and the wires and pipes passing through the walls and floors should be sleeved and sealed with non-shrinking and non-flammable materials.

　　(two) lighting

　　1. The lighting equipment of barrier environment equipment should be kept airtight and clean. The lamp must be installed on the ceiling. If it is installed in a concealed installation, the installation gap must be sealed. The lampshade must be made of materials that are not easy to break and have high light transmittance.

　　2. The illumination of laboratory animals (such as chickens and mice) must be adjustable.

　　3. Set the main switch of the work light.

　　(three) automatic control

　　Automatic control, television monitoring system, and communication equipment have become an important part of modern standardized laboratory animal facilities, and are becoming more and more important in the safe operation and management of laboratory animal facilities. Play a role.

　　1. The automatic control system follows the principles of economy, safety, reliability and energy saving, and the operation should be simple and clear.

　　2. The barrier environment facilities must be equipped with an access control system. Take measures to interlock the doors of the buffer room and ensure that all doors with interlocking function can be opened and closed in an emergency.

　　3. The air supply and exhaust fans in the barrier environment should be equipped with normal operating instructions. If a fan fails, you can trigger an alarm and activate the corresponding backup fan automatically or manually. The air supply and exhaust fans must be tightly coupled, and the fan starting sequence must meet relevant requirements.

　　4. The power distribution of the air conditioning system of purification barrier environment facilities should be set to automatic and manual control.

　　5. The electric heater of the air-conditioning system must be interlocked with the blower, and must be equipped with air-free shutdown, overheating shutdown protection and alarm devices. The metal conduit of the electric heater must be grounded, and the pipes and insulation materials that pass through within 800 mm before and after the electric heater and the parts that may cause fire (such as fire sources) must be non-flammable.

　　6. If the temperature, humidity or pressure difference of the barrier environment equipment exceeds the setting range, please set an effective sound and light alarm function.

　　7. The automatic control system must meet the temperature and humidity requirements of the control area.

　　8. Reliable communication methods are required inside and outside the purification zone of barrier environment facilities.

　　9. Install necessary camera monitoring equipment in the production area (experimental area) of the barrier environment facility.
