What happens to children if safety precautions are not taken inside the home? How many deaths happen a year?

Which precautions? There are numerous home safety precautions that can be taken. From pool safety to covering outlets to corner pads. Each of these has a different "return". Some, like padding corners on a table, do not prevent death. Others, like putting four walls and self-locking gates around a pool, save hundreds if not thousands of preventable deaths a year.
