A child may not use any type of toy or equipment that explodes or that shoots things, such as caps, BB guns, darts, or fireworks at the child-care center or on field trips. These types of toys and equipment are not allowed at your operation unless your operation is located in your home. If your child-care center is located in your home, you must keep any such toy or equipment in a locked cabinet inaccessible to any child during your hours of operation.
