The school has too many new students every year and does not have many classrooms, so it temporarily builds prefabricated classrooms to teach sixth grade students. Some parents expressed dissatisfaction, saying that if the prefabricated houses were put into use after they were completed, formaldehyde might be present which would affect their children's health! He even said that he felt dizzy and nauseous after being there for 10 minutes! 
First of all, based on the overall enrollment situation, the school's emergency plan of using prefabricated houses as classrooms is feasible. The construction of traditional teaching buildings cannot be completed in one or two months. Prefab houses are only used as a temporary transition. It’s not that prefab houses cannot be used as classrooms, but that some parents cannot accept their children staying in classrooms made of prefab houses. Dizziness and nausea are caused by psychological reasons, and the prefabricated house will not take the blame! There are also cases in Nanjing that use prefabricated houses to build classrooms because there are not enough classrooms in the school. The advantage of temporary construction products is that they can be quickly set up and put into use. They are not limited to construction site projects, but can also be used in nursing homes, schools, commercial streets, high-end office buildings, sales offices, hotels, affordable housing, apartments, municipalities Temporary housing, training camps, etc. Do you really feel dizzy and nauseous after just 10 minutes? If this is the case, then aren’t our infrastructure builders in China vomiting every day and suffering health damage? Because before construction began, the project department and staff dormitories were built in prefabricated houses to be used as temporary offices, residences, and kitchens. Fangcang hospitals are also built with mobile homes; mobile homes can also be used to quickly build barracks during wartime.
Secondly, let’s talk about whether the materials used in prefabricated houses contain formaldehyde. The wall panels are made of double-sided iron sheet sandwich rock wool wall panels, which play the role of fire prevention, sound insulation and heat preservation. The top insulation is also fireproof rock wool. The frame is mostly steel. The baking or spray painting process of the frame is prefabricated in the factory and will not be sprayed on site. Even if there is formaldehyde in the paint, it has been very, very little after transportation and construction. Compared with traditional building paint, it is already very environmentally friendly. If you are really worried about formaldehyde exceeding the standard, you can find a third-party agency to conduct testing to dispel parents' concerns.
