NORWALK - Norwalk firefighters took part in some critical training that they say helps keep residents and their homes safe. 

Firefighters from all over the city were on hand for the specialized training. Firefighters say you never know what is on the other end of a 911 call, so being prepared is very important.

They train not only for scenarios that involve fighting fires, but also for instances when someone is trapped in a confined space or needs to be rescued after a car crash. Firefighters say when rescuing someone from a small space, it's important to remain focused when you are being lowered down.

The training takes place once a year. This year's refresher course took place inside Norwalk's newest firehouse, which is also home to a modern training facility.
