ABSTRACT:
An emergency door opening tool set includes a screwdriver for removing a latch assembly cover plate, a second and a third tool for opening a locked door. The second tool includes an elongated bar with a mass of metal at one end thereof and an opening or recess in the shape of an outwardly projecting portion of the lock. A transverse force is applied to the elongated bar to break off the outwardly projection of the lock. The third tool includes an elongated bar, a T-shaped handle at one end thereof and a latch turning element at the opposite end. After removal of the broken off portion of the lock the third tool is inserted into the lock assembly and turned to retract a latch bolt from the striker plate. The set also includes a pouch or bag to carry the tool set.
