Allow for temporary door locks during emergency situations

HB 651 allows public buildings to use temporary door locking devices during shelter-in-place or emergency lockdown situations. These devices can secure doors, including fire exits, as a limited exception to the fire code. The bill defines these devices with specific safety requirements, such as being removable from the egress side without a key, not permanently mounted, and integrated into building safety plans and training. Their use must also be approved by the local fire department, law enforcement, or code official.
