Objects Containment Specifications Suggestions

These are suggestions for containment specifications from Engineering Department. In recent years, the number of objects has been increasing at an accelerated rate, and in order to contain these objects using limited time, humans, and material resources, it is necessary to reduce the cost per containment.

However, if we focus only on cost-cutting and neglect the principles of Secure, Contain, Protect, it may cause a great disaster not only to the Foundation but to humanity as a whole. To prevent this from happening, we suggest the standardization of the items needed for containment.

Standardization of items will reduce the number of design drawings, narrow down the items to be procured, unify the production line, and standardize transportation and maintenance to keep costs low while maintaining safety. Not only that, it will also help the researchers to develop more specific Special Containment Procedures; because it will help them think about “why”.

Why can't standard items be used? Will the material not fit, is the object too big to fit, does the object have risks of destroying the standard items, will it break out of standard items, will it interfere with other objects? The process of considering each of these issues and choosing what to use to contain them is a great way to review the nature of the object.

And if, after thinking about it, it is decided that a special order is necessary, please don't hesitate to place an order. Because the way of using the cost that have been saved is to use it for really necessary “Special” Containment Procedures.

I suggest the following specifications for standard items.

Standard Containment Locker (Low-Threat Object Containment Locker)

Standard containment locker was designed to be the first choice for managing objects that were determined to be lockable in a box.

Assumption of Requirement Specifications

  • The box must be able to secure, contain, and protect low-threat objects without problems (safety)
  • Have a minimum level of resistance to damage that does not allow a single containment breach to lead to a chain of containment breaches (impediment resistance)
  • The specification should be able to contain more objects in a uniform manner (versatility)
  • Structure and materials that can reduce the cost of manufacturing and maintenance (economic efficiency)

The higher up these 4 requirements, the more priority is given to them, but if the lower requirements are neglected, the significance of standardization is diminished. In other words, standard containment locker must meet all 4 requirements and should not be used to contain objects that cannot meet the requirement.

Common Elements

In order to meet the 4 requirements, the standard containment locker is composed of the following elements.

Materials electro-galvanized steel sheet and aerated concrete Impediment Resistance
Economic Efficiency
Security dial and cylinder double-lock Safety
Impediment Resistance
Fire Resistance General Type: Keeps the temperature inside the chamber below 177℃1 for more than 4 hours against heating at 1200±10℃
Device Type: Maintain the temperature inside the chamber at 52℃ or lower for at least 4 hours against heating at 1200±10℃
Impediment Resistance
Water Resistance Water discharge of 100±5L/min at 100kPa from a distance of 3m, continued for at least 3 minutes from all directions, no flooding Impediment Resistance
Standard Accessories Key, nameplate, chamber tray (choose from plastic, wood, steel, or special materials) Versatility
Option Interior walls made of various materials (please specify before placing an order, and be aware that some materials may reduce the usable dimension) Safety
Installation Can be connected vertical (length of protrusion for connection/depth of hole: 15mm), bottom hole is connected to anchor bolt Versatility
Economic Efficiency
Durable Life To be renewed every 20 years Safety
Economic Efficiency

Supplemental Size and Installation Instructions

Standard containment lockers are designed to be stacked vertically with the borders on opposite sides. The horizontal type has the same dimension as 2 small lockers next to each other, the vertical type has the same dimensions as 2 lockers stacked and connected, and the medium type has the same dimension as 2 lockers placed in a 2×2 configuration. The large type lockers are twice as deep and are designed to be embedded in a place where 2 rows of lockers are placed in a row other than near a wall.

Vertical stacking should be less than 1.5m high, and standard small containment locker should have no more than 6 levels. This is because containing objects above eye level, regardless of whether they are objects or not, can lead to accidents when taking them out.

Size Name Dimensions Contained Items Examples
Small External Dimensions: W310×D470×H250
Internal Dimensions: W230×D330×H140
Documents no larger than A4, books, laptops up to 13~14 inches, small items, and shoes
Horizontal External Dimensions: W620×D470×H250
Internal Dimensions: W540×D330×H140
A3 documents, books, and laptops larger than 14-15"
Vertical External Dimensions: W310×D470×H485

Key Management and Comprehensive Security

Key management is done by the key box connected to the Kant counter. If an anomalous Hume level is measured due to reality altering ability and so on, the key box will be locked. The corresponding key can be retrieved only when the object number, ID of personnel with security clearance, and password are correctly entered within the normal Hume level.

Only 1 key can be taken from the box at a time, and it will remain locked until it is put back. Please take out and transfer them one by one even when conducting cross tests. This is also a precautionary measure against unintentional crosses before the experimental environment is ready.

Combining these key management methods with the structure of the standard containment locker itself, the items inside are secured, contained, and protected by the following elements.

  • Guarding standard containment locker and key box rooms
  • Monitoring of Hume levels with Kant counter
  • Digital ID and password management with the Foundation database and key box
  • Analog password management using dial keys
  • Fire resistance equivalent to a fireproof safe and water resistance equivalent to IPX6

Management Guide

Standard containment lockers can contain a variety of objects by locking them up. At the same time, there is no need to add any more functionality than locking until the 4 requirements become unbalanced. Objects that require such functionality must be combined with other equipment or environments, or contained in custom-made boxes as before.

  • Safety — There are 2 points that the researchers should consider regarding safety. The first is whether the locker can be broken from the inside, and the second is whether it can protect the objects inside.
Acceptable ・Objects that react to light and try to move (can be secured by closing and locking the door)
・Objects that explode when they come in contact with metal (can be contained by non-metallic linings and chamber trays)
・Glass objects (can be protected by placing cushioning materials in the chamber)
Unacceptable ・Objects that pass through items and move toward the light (cannot be secured because it is only a physical wall)
・Objects that drip liquids that corrode metal (can only hold the volume of the chamber tray)
・Objects made of alloy, but self-disintegrating (cannot be protected unless the entire mechanism to prevent disintegration is placed inside a chamber)

  • Impediment Resistance — Standard containment lockers are not designed for perfect protection that does not accept any attack of all objects. Protection of objects should be achieved in combination with the security and features of the facility.
Acceptable ・Withstand a fire resulting from a containment breach for 4 hours
・Withstand magma ejected from a volcano (assuming a maximum temperature of 1200℃) for 4 hours
・Withstand water discharge of less than 100kPa due to water pipe breakage or attack from objects
Unacceptable ・Left in the fire for more than 4 hours due to site abandonment and so on
・Exposed to high temperature or pressure exceeding 1200℃ by being put in the crater and so on
・Exposure to complete submersion or release of corrosive fluid

  • Versatility — Even if kept safe and away from unacceptable impediments, standard containment locker cannot contain all items. To take a simple example, it is not suitable for containing sapient life forms. However, the discussion of what is life, intelligence, or emotion is inappropriate as a guideline. So let's assume that you, the reader of this suggestions, are placed in a locker of acceptable size, and let's analyze the issues that arise other than ethics.
Maintaining Functionality You need to eat and produce wastes. Standard items cannot support these safely.
Similarly, objects that need to be supplied or drained to maintain life or function shouldn't be contained.
Even if it's light for photosynthesis or power from an electrical outlet.
Change in Response You can probably endure feeling cramped for about 10 minutes.
But what if the time passes in 30 minutes, an hour…… much less a day or two?
You will be banging on the wall in anger or crying out in fear.
Similarly, objects that change responses over time shouldn't be contained.
Keep in mind that change here is not limited to emotions and stress reactions.
Learning Ability You will get fed up with the inside of the locker and try to get out of the box.
You will then remember how often personnel comes to open the door, or hear the sound of a dial being turned.
Or you might stock up on tools to secretly unlock from the inside when it's “taken out”.
Objects that are sapient at a level that allows them to do so shouldn't be contained.
Chamber Environment In order for you to retain the function of your life, you need to be placed in a certain environment.
Parameters such as temperature, oxygen concentration, and pressure must be within range.
If this is an object, it might require a different temperature or oxygen concentration than you do.
Standard containment lockers don't have the ability to adjust them, so the environment must be maintained in each room where they are installed.
Or use a separate box that has the ability to maintain it, such as a refrigerator.

  • Economic Efficiency — Even though it's the lowest priority of the 4 requirements, cost reduction is an essential motivation for using standard items. If it is thought that forcibly modifying a standard containment locker will increase the cost, consider a custom-made items.
Acceptable Gilded lining (although you will probably be asked to explain why this is necessary)
Unacceptable Standard containment locker made of solid gold (that is not possible for standard)


The Engineering Department suggests standard containment locker as a safe, impediment-tolerant, versatile, and economically efficient means of containment with these combined security and object limitations.
