Before we start to specify which locks are suitable for Emergency exit doors it is very important to understand that these doors should never be equipped with locks that require keys to unlock because during an emergency every second counts and messing with finding a key or struggling to operate the lock can result in getting hurt.
Emergency Panic Bars
known also as push bars are horizontal bars that extend the entire door and are designed to allow quick and easy exit by simply pushing the bar or lean on it.
These bars are typically spring operated and unlatch the door immediately when you push them and there is no need for turning a knob or using a key, exactly what ensures a quick evacuation in case of a fire while visibility may be limited because of heavy smoke.
Local authorities and fire departments mandate this specific bars for emergency exits and also made it a certain standard for accessibility as well.
For example the International Building Code (IBC) and National Fire Protection Association (NFPA) standards provide specific guidelines for the types of locks needed to be used on emergency exit doors.
