Google Safety First (SFF) means that if you are walking, you are using your hands to walk.
Google says it is about keeping your hands free, not just holding your hands.
Google’s safety pins are a set of pins that are designed to remind people to always keep their hands on their hips, shoulders, knees, feet, ankles, and arms.
Google Safety pins are designed for people who walk in a way that doesn’t require a lot of extra strength or coordination.
Google pins come in five sizes: small, medium, large, and X-Large.
