校园专栏-细致部署校园防护，静待学子平安归来| Protect School to Wait for Student Back

In an outbreak, the first quarter of 2020 is lost. So far, there have been confirmed cases worldwide. Although the form of epidemic prevention in China has improved, but we still need to import foreign defense, internal defense rebound. According to the latest notice from the ministry of education, 11 of the country's 34 provincial-level administrative regions have a specific beginning date. When we saw the news that many medical workers in hubei province were returning to their hometown, many students and parents had more expectations for the new semester. But the capital still doesn't have the conditions to start school. Although we are not sure when students will return to school, our support staff are in action to provide the safest campus environment for students.

Supplies have been tight in the market since the outbreak of novel coronavirus pneumonia. The school has been adhering to the principle of material reserve and actively purchasing. At present, there are dozens of temperature measuring guns, thousands of masks, disposable hand lotion, alcohol and 84 disinfectant on the shelves of the epidemic prevention supplies store. At the same time, we also purchase goggles, gloves and other related materials. These materials can not only fully meet the needs of campus epidemic prevention and control during the holidays, but also meet the needs of use after the resumption of classes.

School insists on completely closed management, with only one entrance and exit, guarded by security guards 24 hours a day. The security guards of the gate guard shall check the masks, register the information, verify the condition of returning to Beijing for 14 days, measure the temperature, check the epidemic symptoms, and disinfect the hands of those who can enter the school according to the above requirements.

Every morning and noon, the school will recheck the body temperature of all the school staff (for the staff in the evening late inspection), to maintain a healthy environment on campus.

The school guard will register and confirm each item after receiving the express from the school. The express delivery and other materials entering the school from outside should be sterilized first, and the outer packing should be registered and put in storage after spraying disinfectant.

Good ventilation is the most effective way to improve indoor air quality, providing fresh air, reducing the accumulation of viruses and preventing cross-infection. The school insists on implementing the indoor ventilation guidance issued by the city for disease control, and opens the window for ventilation three times a day, each time for at least 30 minutes, and makes corresponding ventilation records.

The ventilation system is the "lung" of the school indoor environment. In order to block the possible pollution particles in the ventilation system and reduce their health threat to the school staff, the engineering team and the cleaning team carried out deep cleaning and disinfection on all the VRF air conditioners, fresh air units and air purifiers in the teaching building, complex building and dormitory after the Spring Festival. We rinse the ventilation filter net with high-pressure water gun, soak the disinfectant, and finally put it in the sun on the roof to dry, dust the outlet and spray the disinfectant.

The air conditioning of the teaching building and dormitory building of our school is the VRF independent air conditioning of Japanese daikin brand (similar to the principle of household air conditioning), which is sent into the room after cooling/heating. Does not exchange air circulation with other Spaces. There will be no central air conditioning to send polluted air into other space.

The basketball hall, swimming pool and theater in the complex building are the new air units. Each air outlet is delivered by the roof unit from the outside to the large space after filtering the fresh air, so that teachers and students in the physical exercise more safe.

Since January 31, the cleaning team returned to school after the Spring Festival holiday, and has been doing the disinfection work of the whole school for one working day. At the moment the campus is quiet, staff turnover is low, but the disinfection work is not lax. Disinfection has been upgraded from routine once a day to twice a day, with more stringent requirements for areas and procedures. 84 disappear poison, alcohol, ultraviolet ray lamp, aunt people can the usage method of these disinfection means is like a number of home treasure real come. At this time into the campus, often can see the back of the carrying spray disinfection machine, hand sanitizing spray bottle, with disinfection towel a little bit of cleaning.

School has not officially opened, but the school nurses in the school holiday as always involved in the preparation for the epidemic. In addition to the school commonly used epidemic prevention reserves, the health care room combined with the new crown epidemic prevention requirements to purchase enough professional protection materials. When the outbreak start, the school's cooperative clinic trained the resident nurses, and cooperated with the school to formulate and implement the emergency plan and system. As an important part of emergency response, the resident nurses have been able to make clear the prevention and control points, clear emergency procedures, and accurate investigation and statistics.

The school bus drivers and drivers also eager to reunite with the students. During the epidemic period, the motorcade was suspended and on standby, the school bus team implemented the school bus routes for the second semester, and the members were trained in prevention and control measures and prepared for the new semester. The team will carry out the commuting task according to the prescribed workflow. Specifically, all vehicles will be thoroughly disinfected before formal operation, and routine disinfected before two daily departures after operation; Passengers (including students, drivers and licencing officers) should wear masks at all times; Health check before getting on the bus. In case of fever (body temperature ≥37.3℃) or suspected symptoms of a new crown, students will be discouraged from coming to school by bus. In the process of driving, the controller should pay attention to the students' physical signs, and check the students' body temperature and register again before getting off the bus. Make separate rides and so on.

We are planning to extend the meal time and implementation of the students by the grade after the start of semester. The cleaning and disinfection of tableware and dining environment will be upgraded in the normalization requirements. Sample and mark various dishes of each meal for inspection.
