Abstract
A lockout tool assembly for locking open a roll-up door that automatically closes without power is provided. A lockout tool assembly may include a lockout tool member, a first lockout plate, and a second lockout plate. The lockout plate may each define a receiving recess, such that when the first lockout plate and the second lockout plate are installed inverse to one another in a closed lockout alignment position, the receiving recesses are complementary in that they form a crossbar restraint receiving aperture. Methods for locking open a roll-up door with such lockout tool assemblies and for removing installed lockout tool assemblies are also provided.
