Short answer: Mount the wall button high, keep remotes out of reach, teach kids that the door is not a toy and never to cross under a moving door, and keep pets inside or leashed while the door moves. Test the photo eyes and auto-reverse every month. Keep children and pets away from springs, cables and the joints between panels, and leave the manual release to adults.

To a kid, a garage door that goes up and down at the push of a button is fun. To a dog, it's the way to the outside world. To a cat, the garage is one more room to explore. That's why homes with kids and pets need a few extra habits around the biggest moving thing in the house.
None of this takes much time. It's mostly setup, a couple of conversations and a five minute test each month.

Keep it simple and repeat it.
Older kids who use the garage on their own can learn to check that the doorway is clear before pressing the button, and to watch the door until it's fully closed.
Two quick tests tell you whether the door will stop for someone in its path. Pass a broom handle through the sensor beam while the door is closing, and it should stop and reverse. Lay a 2x4 flat under the door and close it, and it should reverse when it touches the board. Never test with a person, a child or a pet. Our step by step guide to testing the sensors and auto-reverse covers what to do if either test fails.
If either test fails, don't count on the opener to stop for anything until it's fixed. Have a professional check it rather than adjusting the opener's settings yourself.
Kids shouldn't pull the red release cord. Adults should only pull it with the door fully closed, because a door with a weak or broken spring can drop quickly once it's off the opener. Here is how to use it safely in a power outage.
For the basics every household should know, see garage door safety every family should know. And if you hear a loud bang from the garage, keep everyone out and read our spring warning signs before anyone touches the door. A yearly safety inspection covers the sensors, springs, cables and balance, the parts that keep the door predictable.

High enough that small children can't reach it, and where you can see the door while pressing it. Check your opener manual for the minimum height it gives.
Leash or hold your dog while the door is moving, and keep the door between the house and the garage closed so the dog can't get to the doorway on its own.
The sensors sit a few inches above the floor and can miss a very small animal lying low. That's why the auto-reverse should also work. Always look before closing and test both systems monthly.
Mount the wall button high, keep remotes out of reach, and use the lock or vacation mode on the wall control if your opener has one. It turns off the remotes until you switch it back.
