Can't get through. The fire protection rating of the wood floor is B2. But in places like training institutions, the fire acceptance is very strict, and B2 can't pass the fire acceptance. Fire acceptance criteria of training institutions:

1. The fire resistance rating of the training institution building should not be lower than Grade II. The national fire technical specification indicates that it can be level 3 or level 4 when meeting specific requirements.

2. Generally, try to set the fire resistance rating of Grade III and IV, because it must be considered that the evacuation of young children is slow and the evacuation time is long.

3. Multi-storey buildings should not be set above the second floor. Interior decoration materials: ceiling should be Grade A. The materials such as walls, floors, partitions and curtains should not be less than B 1, and other furniture, teaching and entertainment facilities should not be less than B2.
