Incombustible theme parks

The other day I went to a theme park with my child.
I was sometimes worried when I was riding an indoor mobile attraction.
That’s about flame prevention and fire prevention at facilities.

Cloth and plastic which seem to burn well are used.
For example, clothes worn by dolls. Are these flame protection measures taken? I thought.
I don’t know what flame protection rules apply to attraction facilities, but I think that some kind of countermeasures are required because it is a closed space.
At that time, I think that our soufa can not be used.

Regarding fire and flame protection measures for decorations, we are often contacted by people in the landscaping industry to use them.
I am glad if you can help by spraying.
