The Light Containment Zone is one of the four major areas in SCP: Secret Laboratory, which serves as the area where Class-D, Scientists, and SCP-173 will spawn. It is also the location of SCP-914. After 11 minutes and 45 seconds have passed, the zone will begin the decontamination process.

Hallway Codes

Above each doorway in the Light Containment Zone is a 4 digit code with two characters on top and two on the bottom, allowing for any passerby to identify the room on the other side of a door without needing to open it. Each code is representative of each kind of unique location and each generic one as well, presenting separate parts such as two hallways with different numerical designations to keep them different from each other.

There are currently 14 unique types of these codes:

Area Hallway Code Scientist Spawn? COM15 Location? Notes
Curved Hallway HC__ No No Number between 01 to 09, cannot repeat to other areas of the same type
Straight Hallway HS__ No No Number between 01 to 09, cannot repeat to other areas of the same type
Three-way Intersection IT__ No No Number between 01 to 09, cannot repeat to other areas of the same type
Four-way Intersection IX__ No No Number between 01 to 09, cannot repeat to other areas of the same type
Checkpoints EX-_ Yes No Can either be 'EX-A' or 'EX-B', depending on the Elevator System.
Airlocks AL0_ No No Can either be 'AL00' or 'AL01'.
Bathroom WC00 Yes Yes
Armory ##00 Yes *Yes *The Armory provides a COM15 Pistol of its own, separate to the one free COM15 Pistol that is randomly spawned in other locations.
Class-D Chambers CD01 No No
Office PC15 No No
SCP-012 Chamber #012 No Yes
SCP-173 Chamber PT00 No Yes
SCP-372 Chamber GR18 Yes Yes
SCP-914 Chamber #914 No No

Areas

Heavy Containment Zone Checkpoint

EX Exit
EX-A
EX-B

This room is the gateway to and from the Heavy Containment Zone. There are two checkpoints found within this zone, each connecting to either elevator system A or B, respectively.

A keycard with checkpoint access, or operation by an SCP is required to open the checkpoint up. As with all checkpoints, the doors will remain open for a few seconds before closing after a few warning beeps.

Above the checkpoint, a there is a monitor counting down to Light Containment Zone's decontamination.


Airlock

AL
AL Airlock

The airlock is a red-lit room with two doors on each side and a small dark side-room. Upon pressing either button, the inward doors will toggle between one opening and the adjacent door closing. The smaller side-room serves little purpose other than to hide in.


Bathroom

WC Hallway
WC Loot Sink M
WC Toilets

The bathrooms are located off the side of a low-ceiling hallway by a single door with a "WC" sign overhead. In the hallway, a medkit may possibly spawn next to the door as seen above. When going inside, the bathroom consists of separate sections men and women.

In the male side, there is a chance for a keycard to spawn on the ground. There is also a chance for a COM15 pistol to spawn on the sink, as well as being able to hold another keycard. In the women's side, there is a chance to find a keycard on the sinks or on top of the toilet. Both sides can provide only two types of keycards, either Scientist or Janitor keycards. 


Armory

--00
--00 Armory

The armory is connected to the main hallway by a tiny room that a Scientist can spawn in. From this interlude is a locked door which requires Tier 1 armory access to open. It contains two workstations and weapon manager tablets, an MP7, a P90, a COM15 Pistol, several flashbangs and grenades, and some 9mm and 5.56 ammo magazines.


Class-D Cells

CD
CD Cells
ClassD Artwork

The spawn location of all Class-D players. There is nothing of direct importance in this area as it simply leads into the zone proper. In the far back of the room, the two winning pieces of artwork from the SCP:SL 2018 art contest can be seen.


Office

PC
PC Room

The office is organized into an arrangement of desks with computer monitors, phones, and other utensils on top of each. A Scientist keycard always spawns within this room, but it will be randomly distributed onto one of the sixteen possible desks. A Standard locker can possibly spawn next to the left of the door and up to two wall mounted medical lockers may spawn along the right wall.


Greenhouse

VT0000
Vt00

The Greenhouse is a hallway room, which on one side divided to the hall by glass, contains three plots of dirt, filled with plants. The side adjacent to the greenhouse space contains a small room that has the chance to spawn a standard locker, wall mounted medical locker or bulletproof locker.


SCP Containment Chambers

Unlike the neighboring Heavy Containment Zone, Light Containment has only one playable SCP that uses these as a spawn point, with all of the chambers having little to no access requirement to open and explore.


SCP-012's Chamber

-0
Room 012 Loot

SCP-012's containment chamber consists of four rooms, a hallway leading up to a control room and the containment chamber itself. There is a doorway that closes off the control room which requires Tier 2 Containment chamber access to enter, with another doorway between the chamber and control which requires no access tier. A Zone Manager keycard will always spawn on the control room dash, with the chance of the COM15 Pistol spawning here as well.


SCP-173's Chamber

PT
PT Staircase
PT Chamber

SCP-173's main chamber is accessed via a staircase. Before entering this chamber, there is a small room at the top of the staircase which has a chance for a COM15 pistol or bulletproof locker to spawn inside.

Inside the main containment area there is an inaccessible door to the right and a balcony to the left with a control room on the upper level. SCP-173 will spawn in its containment chamber with a short timer before its large blast door can be opened. Afterwards, it can be manually opened and closed without any form of clearance.


SCP-372's Chamber

GR
372 Chamber

SCP-372's containment chamber consists of a small room that has a chance to contain a locker. There is also a chance of a COM15 pistol spawning in the glass containment unit in the center of the room.


SCP-914's Chamber

-9
1092258129 preview 914

SCP-914's containment contains SCP-914 and several shelves of static items. The room itself is locked behind a large blast door which requires a Tier 1 containment chamber access to open.

Trivia

  • The Light Containment Zone was overhauled in Patch 6.0.0, altering the design of the hallways as well as introducing the unique hallway codes above each doorway.
  • Despite changes to all the hallways and rooms of the zone, the Bathroom is the only kind of room that is not a dead end which fails to post the code of the proceeding room.
  • An object known as "Hubert ball" can be found using noclip in Light Containment Zone inside the air vents near the ceiling.
  • Many rooms have a chance to contain the COM15 Pistol. This is because it is placed randomly in one of these rooms.
    • There can only be one COM15 Pistol that spawns in this manner, allowing players to potentially deduce where the weapon is by checking other locations.
    • Of these rooms, the Washrooms is the only COM15 location that is not related to any SCP.
