Selection of decorative materials: Early educational institutions choose decorative materials with waterproof, anti-corrosion, anti-rust and environmental protection characteristics. After the floor tiles are laid, it is best to add a non-slip carpet to prevent children from slipping. Figure 2. Doors and windows: the doors and windows of early education institutions should be provided with observation windows. The height of the window should be consistent with the height of the child, so that the teacher can easily observe the situation. It is best to have windows in the bathroom to facilitate ventilation. 3. Circuit laying: In the environmental facilities of early education institutions, PRZEWOD connectors must be hung with tin and wrapped with waterproof tape and insulating tape, and their positions should be located in places where children can hardly find or reach them. The flame retardant tube must be placed on the wire body, and the position of the switch should be determined according to the height of the child to ensure the safety of the child and the convenience of reasonable use. 4. Color matching: Children's eyesight has not been fully developed, so the color matching of early education institutions is too fancy and complicated, which will stimulate children's eyes for a long time and affect the healthy development of children's eyesight. Low-color and high-brightness tones should be used to set off the fresh atmosphere and make the bathroom look spacious and bright.
