Explanation:

Indoor recreation is considered to be the safest recreation site. The indoor recreational site can be used to conduct the sports activities and leisure time activities. These are performed within a building or a business area. These are open for the general public and charged with a fee. The indoor area must be clean and tidy. The floor should be clean and smooth to facilitate smooth walking.

A liquid spill can be of water, sticky substances like wax, vegetable curry, medicinal syrup or other. If the spill is not cleared from the floor it will likely make a person slip down and may be subjected to injury of spine or leg sprain which may take many months to recover.
