Which law prohibits the painting of sitting boards?

At present, there is no law explicitly prohibiting the painting construction of the sitting plate. However, the Technical Code for Safety of Working at Height in Building Construction stipulates that protective measures should be taken when the construction height exceeds 2m.

In addition, the Ministry of Housing and Urban-Rural Development issued the Technical Catalogue of Prohibited and Restricted Use of Residential Municipal Works (2022 Edition), which contains some construction techniques, equipment and materials that are prohibited and restricted, but it does not explicitly prohibit the construction of floor coatings.
