What is the national standard for plastic runways used in primary and secondary schools?
Nowadays, many primary schools have built playgrounds, but if formaldehyde exceeds the standard seriously, it is unqualified and will affect children's health. Therefore, the state clearly stipulates that harmful substances in finished products should not exceed 5 mg cubic meters, and the smell should not be higher than Grade III. When the school is established, we should pay attention to the safety inspection before the start of school to prevent problems. In a primary school in Suzhou, on September 1 day, 2020, when the primary school just opened for use, many parents were inevitably worried.

Because it is newly established after all, if there is serious formaldehyde unqualified behavior in it, it will easily have a serious impact on the child's body. Sure enough, what parents expected really happened. A few days after school started, the child developed symptoms such as nosebleeds and dizziness. After this happens, parents doubt whether there is any chemical residue on the school runway, because there is still a serious pungent smell on the school runway.

At present, the person in charge of the school has told parents that the school has tested it before the school starts, and if there is really a problem with the school runway, it will not start school. Now, if there is such a problem, it will also be responsible for sending sick children to the hospital for examination and testing the materials of the runway. In case of non-conformity, the products will be disposed of and the relevant responsible persons will be held accountable. When the school checked, it was found that four of them had nosebleeds due to illness.

In this case, parents must be very flustered. After all, children have health problems at school, and many parents are afraid to send their children to school. Parents believe that even if students have a history of nosebleeds, they should not have nosebleeds on such a large scale. They think it is the influence of the school playground that makes children have such symptoms.

The person in charge of the school also said that if you are not at ease, you can take your children home. Before the test results come out, the school will give your child counseling and make up lessons for your child free of charge after school. At present, the country still attaches great importance to children, because after all, they are the hope of the future. If there is any problem, it is a very serious matter. If something goes wrong in the school playground, it will be severely punished.
