Thinking back to when the kid was 1, the key issues were keeping the child off the stairs, and removing anything that was within reaching distance from the floor -- i.e. lower than about 30"
We didn't bother with kid locks in the kitchen or other cabinets as it was easier to place a kid proof gate across those areas that were "entry only with an escort"

if it can be used as a hand hold a kid will pull it down or pull themselves up on it.
look for sharp edges at around adult knee to mid-thigh height
