The design of the traffic space of the Animal and Plant Research Laboratory should focus on the movement of cages and animals through the institute. In many cases, animals are sent to the building, transported to the upper floor through a dedicated elevator, and then placed in the basement or top floor of a building to facilitate security, confidentiality, and safety. If you choose between the basement and the top floor, the top floor is the first choice because of its proximity to exhaust fans and other mechanical equipment.
After the animals are inspected and no longer need to be quarantined, they are taken out through a "clean" corridor and sent to a storage room or small room. When cages or cages need to be cleaned, they are transported to the cage washing site through the "dirt" corridor. If possible, a pass-through cage washer is preferred to separate the clean and dirty sides. To reduce the chance of cross-contamination, multiple barriers can be provided, such as the entrance porch, the antechamber of the dedicated room entrance, the small room or ventilation rack in the veterinary, and the miniature isolation rack that can be independently ventilated in the cage floor. Clean corridors should be positive pressure and negative corridors along dirt corridors.
Through the evolution of human beings, they walked on all fours to walk upright. Through the investigation of the development history of world furniture, researchers found that after walking upright, humans found that sitting was conducive to reducing fatigue in their daily activities, so they invented the sitting device. This way of sitting work subsequently passed down, but as people sat in the office more and long time, people gradually realize that sedentary instead not conducive to the improvement of work efficiency, people begin to try to sit stand alternating office, gradually standing table also occurs, use height adjustable table stand office become a popular way of health office.
Whether sitting for a long time or standing for a long time has a bad physiological impact on the human body, only sitting and standing for an alternate office is the most scientific and healthy way of working.
