A:Answer Thanks for sharing your concerns. Since our primary audience for LEGO® DUPLO® is young children, safety is always priority number one! All DUPLO sets undergo rigorous testing and must meet the strictest safety standards. This includes pull tests, impact tests, compression tests, and step tests. This means any DUPLO element your child plays with won’t cause harm. Feel free to get in touch at LEGO.build/Service-BV if you need more information or have additional questions.- Michael, LEGO® Customer Service
