Dalek-Commanded Laboratory Containment Door

Distinct from the laboratory's red warning light fixture, which serves as a visual verification tool during antidote tests rather than a physical containment barrier.

2 appearances

Purpose

To contain and secure the Dalek biological weapon facility, preventing unauthorized access or contamination escape.

Significance

The door's failure in conjunction with Wester's sabotage becomes the moment the Daleks' own weapon turns against them, exposing the fragility of their supposed invincibility.

Daleks declare readiness to deploy bacteria bomb

The heavy steel laboratory door serves as the primary barrier against external contamination and escape, its reinforced mechanisms designed for total isolation. When the bacteria mist erupts, it becomes the focus of frantic Dalek efforts to prevent further spread. The door symbolizes both the false security of containment and the immediate failure of Dalek operational readiness.

Before: Securely sealed industrial door with reinforced locking mechanisms, appearing impregnable to biological intrusion.

After: Emergency-barred against external threats as Daleks attempt to contain the disaster, though the deadly mist has already infiltrated the chamber through multiple breaches.

Wester sacrifices himself to release bacteria mist

The containment door becomes a critical mechanical blockade as Dalek orders demand it not be opened. The door’s locking mechanisms engage under command protocols, yet simultaneously, the bacteria mist renders the entire chamber a deathtrap. The door’s role shifts from security to entrapment, sealing the Daleks inside their own doom.

Before: Secured and operational, monitored by Dalek systems.

After: Locked per Dalek command; functionally becomes a barrier ensuring mutual annihilation.
