No owner shall provide an inflatable for commercial use in this state by others unless the owner complies with this section.
Subd. 3. Protection against injuries from falls.
An inflatable that is in commercial use must be placed in a manner that complies with ASTM Standard F 2374.07, adopted by the American Society for Testing and Materials, including any future updates to that standard.
Subd. 4. Supervision by trained person required.
No owner of an inflatable shall allow commercial use of the inflatable unless a trained supervisor is present in close proximity to the inflatable and is actively supervising its use.
