First, the air tightness test is qualified to be confirmed.
Jilin University Table Response: According to the Indoor Air Quality Standard implemented in 2003, the standard value of formaldehyde is not more than 0. 1mg/m3, and the indoor air quality test results of the third and fourth student apartments in Beiyuan are all qualified. But the students are not clear about the details of the testing institutions. The formaldehyde detection method is very strict, which requires the placement of furniture and the location and quantity of measuring instruments. Therefore, Jida wants students to rest assured that these details must be understood by students. Only when students know the whole detection process can they confirm whether formaldehyde exceeds the standard. So from this perspective, students can't live in new dormitories for the time being.
Second, the decoration completion time
According to Jida's response, the new dormitory is June 30th this year, less than two months from now. You should know that decoration pollution is very serious. Generally, after the renovation of new houses, in addition to maintaining long-term ventilation, some people will put fresh air systems or air purifiers to speed up the removal of formaldehyde. From Jida's response, we didn't see the school's measures to deal with formaldehyde in the new house, but it was tested by professional institutions under the questioning of students, so from this perspective, the renovation of the new house didn't take a long time to complete.
Third, there is a big gap with students' test scores.
Although the school has found a professional testing institution, the data gap is too big. Even if the student's detection position is wrong, is it true or not that the formaldehyde in the new dormitory wardrobe exceeds the standard? The school did not explain, but said that the location selected by the three testing institutions according to the national air sampling standard was the center of the bedroom space, which was consistent with the breathing area of people, rather than the internal closed area such as wardrobe and other furniture. It can be seen that at least the formaldehyde value in the internal closed area is likely to exceed the standard, indicating that it is still harmful. In this case, what the school should do is not to speed up the admission of students, but to find ways to remove formaldehyde as soon as possible.
In addition, the national standard GB 50325, version 20 10 of the Code for Indoor Environmental Pollution Control of Civil Construction Engineering, stipulates that houses and school classrooms belong to a class of civil construction projects, and the formaldehyde content shall not exceed 0.08mg/m? . According to this standard, the new dormitory of Jilin University is unqualified. For the safety of students, please take the indoor air quality of the new dormitory seriously. Only by solving these problems can students feel at ease. In addition, schools should strengthen communication with students and gain their recognition. In addition, even if you stay, the school should do a good job in formaldehyde control and give students a healthy living environment.
