A prevention flame in a theme park?

I went to a theme park with a child the other day.
When taking part in an attraction of indoor mobility, I was interested suddenly.
That’s about a prevention flame in facilities and fire prevention.

The cloth and the plastics which seem ardent well are used.
For example dolls are worn clothes. Are these given to any prevention flame measures? I was thinking.
I don’t have knowledge of what kind of prevention flame regulation is applied to attraction facilities, it’s closed space, so I think some’s measure may be desired.
I’m thinking our soufa can’t use it in such case.

You’re often informing me of a decorative fireproofing prevention flame measure from a person of landscape gardening and are using it.
When it can be useful for blowing, I’m glad.
