A4 — Hazardous Materials And Disposal Complex

1. Summary

Underground Levels: 3

A4 is the most deeply developed of the four auxiliary complexes.

It is located away from the main concentration of personnel and normal logistical activities.

Its purpose is to receive, process, isolate, and store dangerous materials generated by Project Schwarzwald.

3. Function and Contents

The complex handles biological, chemical, radiological, and experimental waste that cannot be managed through conventional disposal procedures.

3.1 A4-L1 — Decontamination & Processing

The first underground level receives hazardous materials through controlled loading terminals.

It contains decontamination chambers, inspection areas, industrial processing machinery, containment interfaces, and cargo-transfer infrastructure.

Personnel and equipment are subjected to procedures determined by the classification of the material being handled.

The hazardous-material railway terminals connect to this receiving infrastructure through separately controlled transfer systems.

3.2 A4-L2 — Hazardous Storage

The second level consists of heavily reinforced storage facilities for materials requiring prolonged isolation.

Different categories of materials are stored in separate chambers.

The architecture emphasizes physical containment, controlled access, remote monitoring, and compartmentalization.

3.3 A4-L3 — Deep Isolation Sector

The deepest level contains the most restricted storage and containment chambers.

It is intended for experimental materials, substances, and biological specimens considered too dangerous for conventional storage or disposal.

Some sectors are permanently sealed.

Others may contain materials whose original purpose is no longer immediately apparent to the player.

The Deep Isolation Sector should be one of the most disturbing environments outside the principal research levels.

Unlike the larger laboratories, its architecture communicates that the facility was designed primarily to prevent something from escaping.

5.1 Surface — Security & Receiving

The visible portion of A4 contains fortified entrances, security checkpoints, industrial receiving structures, loading areas, service buildings, and the remains of historical waste-handling infrastructure.

The surface is surrounded by additional security precautions reflecting the dangerous nature of the materials stored below.

6. Connections

A4 is directly connected to the biological research levels D3 and D5 through specialized underground transportation systems.

6.1 Relationship to D3 and D5

D3 ↔ A4: Transportation of contaminated laboratory equipment, hazardous medical materials, biological waste, and other dangerous substances.

D5 ↔ A4: Transportation of materials generated by advanced biological experimentation, including substances and experimental remains requiring special containment.

These connections are independent.

An incident affecting one transportation line should not necessarily disable the other.

The railways incorporate sealed transfer points and infrastructure intended to prevent contamination from spreading into unrelated facilities.

The incineration infrastructure associated with D3 and D5 remains part of those research levels.

A4 complements those installations by handling materials requiring processing, storage, or isolation elsewhere.
