Key Points of School Air GovernanceThe site includesThe classroom,Toilet, canteen,Laboratory, etc.These places.Personnel concentration, confined space, odor sources,Very easy to cause air pollution.

▲ The classroom is crowded
The 3. laboratory is one of the most frequent places for students besides the classroom, and it is also the place with the most pollution sources, such:
1. Chemical odor:Student laboratories often use a variety of chemical reagents, which may produce pungent odors, such as sour, alkaline, organic solvent, etc.
2. Burning smell: There may be burning experiments in the laboratory, such as burning candlesticks, alcohol lamps, etc., which will produce burning odors.
3. Biological odor:If biological experiments are carried out in the laboratory, such as cultivating bacteria or fungi, special biological odors may be produced.
4. Instrument and equipment odor:Some instruments and equipment used in the laboratory may produce special odors, such as electronic odors of electronic equipment and lubricating oil odors of mechanical equipment.

The 4. canteen is also an important place for school life, and it is also the place with the most pollution sources, such:
1. Kitchen odor:
the school canteenDue to the large number of users and the high frequency of use,Is the most prone to odorWhen the meal time comes, delicious food is often accompanied by unpleasant kitchen odors.
▲A school canteen can accommodate 600 people at the same time
According to the different sources of odor, the impact of odor on people is multifaceted.Odors formed by chemical pollutants are the number one killer of odors., lightIt stimulates the respiratory tract, causing discomfort symptoms such as coughing, sneezing, and tears, and in severe cases causing various respiratory diseases and even poisoning. Long-term exposure to the odor of the environment, can lead to headache, fatigue, insomnia and other physical discomfort, and even shorten life. In addition, odor can also affect people's mood and mood, reduce work efficiency, and even cause health effects.
For schools, air odor can also bring a series of problems. For example, the dissatisfaction of teachers and students with odor will lead to complaints and increased conflicts with parents,Affect the reputation and image of the school. Poor air quality canAffect the learning experience of teachers and students, resulting in the loss of students,And then have a negative impact on the running of the school. In addition, some sensitive populations,For example, people with allergies may have allergic reactions, which increases the responsibility and risk of the school.
For the air management of key places in schools, it is suggested that schools should solve the key problems affecting the school running, suchGive priority to public areas and places with more complaints.. For the effectiveness of governance to take long-term tracking means, even.Presentation of the results of governance in digital form to teachers and students, Let teachers and students rest assured while reflecting the school's sense of responsibility and influence, and increase the trust between the school and teachers and students,differentiated school running.
The evaluation of the effect of air treatment can be considered from several aspects.
intuitive feeling: Judging whether the effect is reflected through people's intuitive feelings (There will be misjudgment, some odor itself is harmful gas, not recommended).
online monitoring: Use online monitoring to collect air quality indicators and compare and judge with reference to the national Indoor Air Quality Standard (Scientific basis and relatively high cost performance).
Third-party testing: Please ask a qualified third party to do on-site air quality testing and identification (authoritative, but due to the real-time flow characteristics of air, oftenUnable to track process changes)
air quality assessment: Air quality evaluation is a scientific and systematic air quality evaluation method based on the national Indoor Air Quality Standard and the above three points. Users with conditions can askShanghai Indoor Environment Purification Industry Association Air Assessment Center("GOOD AIR" air quality assessment) To do a scientific and comprehensive air quality evaluation and obtain the corresponding grade award, which is reflected in the determination and self-confidence in air governance, and demonstrates the responsibility and responsibility for people's livelihood and health.
The air governance of key places in schools requires the joint efforts of all teachers and students.Students should develop good hygiene habits, such as washing hands frequently and covering their mouth and nose when coughing, in order to reduce the spread of disease.The teaching staff should strengthen the health education for students and improve their awareness of air quality.School management departments should formulate corresponding policies and measures to ensure that the air quality of key places in schools meets the standards.
In short,Air governance in key school placesis an important job,It is related to the health and learning efficiency of students and faculty.Must recognize its urgency, andEffective ways to improve air quality.Only with the joint efforts of all teachers and students can weCreate a healthy and comfortable learning and working environment.
