Scores are given to hinges, door locks, panic bars and other locking gadgets and relevant elements.

In conjunction with these smoke seals there requirements to be a non-flamable threshold amongst the flooring and door sweep. These seals are in place to defend the occupants of an adjacent room from smoke or poisonous gases released from a fire, and are designed to enable far more time for evacuation from the fire zone.
