Refuge Chambers (Refuge Bays) by SomNandi Industries

Emergency Safe Haven for Hazardous & Confined Work Environments

In critical situations where evacuation is not possible, a mine refuge chamber (also called a Refuge Bay / Refuge Station) provides a sealed, life-sustaining environment designed to protect personnel until rescue or until the threat subsides. These underground refuge chambers serve as a crucial component of any comprehensive disaster prevention system.

At SomNandi Industries, we design and manufacture engineered refuge solutions that support human survival during emergencies such as fire, toxic gas release, smoke ingress, oxygen depletion, explosions, and operational incidents—especially in high-risk industrial and underground conditions. Our design principles focus on creating robust emergency refuge systems capable of withstanding the harshest environments.

Refuge Chambers (Refuge Bays) by SomNandi Industries

What is a Refuge Chamber?

A mine refuge chamber is a secure, enclosed shelter built to sustain life during an emergency by maintaining a safe internal atmosphere with essential survival provisions. This life-support system includes breathable air, water, temperature control, and a communication system to ensure occupants remain in contact with rescue teams.

Underground refuge chambers are used as designated safe zones when personnel cannot exit an area safely due to blocked escape routes, smoke, toxic gases, or structural hazards. These chambers function as rescue capsules, offering a temporary but critical safe haven until external assistance arrives.

Why Refuge Chambers Are Required

In industries such as mining, tunnelling, underground construction, chemical processing, and heavy industrial plants, emergency events can contaminate the surrounding atmosphere within minutes. This is especially critical in coal mine refuge scenarios, where the risk of gas leakage and explosions is significantly higher.

Even when personnel survive the initial incident, the primary threat often becomes unbreathable air caused by smoke, carbon monoxide/carbon dioxide buildup, or toxic contamination. A properly engineered underground refuge chamber ensures workers have a protected environment to survive and stabilize until rescue operations are completed.

Core Systems Inside a SomNandi Refuge Chamber

A refuge chamber must function as a self-contained life-support environment—not merely a reinforced enclosure. Key systems integrated into our emergency refuge solutions include:

1) Breathable Air Management

The chamber maintains air suitable for human survival by ensuring adequate oxygen levels while actively controlling hazardous gases such as carbon monoxide and carbon dioxide.

2) Sealed & Protected Habitat

Occupants may need to remain inside for unpredictable durations. The internal layout is engineered to remain habitable, safe, and structurally secure, while accommodating both occupants and life-support equipment under extreme conditions.

3) Temperature & Humidity Control

Heat buildup occurs rapidly in sealed environments, particularly with higher occupancy. Effective cooling and humidity regulation are critical survival requirements—not optional features—for maintaining safe refuge conditions.

4) Backup Power Supply System (Stand-Alone Mode)

During emergencies, external power sources may fail. Refuge chambers are equipped with independent backup power systems to ensure uninterrupted operation of ventilation, cooling, lighting, and communication systems.

Refuge Chambers as Part of Your Emergency Response Plan (ERP)

Refuge chambers play a decisive role in safeguarding personnel when primary evacuation routes are compromised or when immediate escape is not possible. Designed to provide a protected, life-sustaining environment, they significantly enhance survival outcomes during underground and confined-space emergencies such as fires, explosions, toxic gas releases, or structural failures.

As an integral part of a site-wide Emergency Response Plan (ERP), refuge chambers function as strategically located safe havens. They serve as designated muster points where personnel can seek shelter, stabilize their condition, and remain protected while rescue and extraction operations are coordinated. By maintaining breathable air, controlled temperature, communication systems, and essential life-support supplies, refuge chambers extend the critical survival window during high-risk incidents.

However, the effectiveness of refuge chambers extends beyond their physical installation. Comprehensive workforce training and operational readiness are essential to ensure the system performs as intended during an emergency.

Applications & Use Environments

SomNandi Industries Refuge Chambers are suitable for a wide range of underground and high-risk industrial applications, including underground mines and shaft operations, tunnel construction and subterranean infrastructure projects, petrochemical and hazardous processing facilities, industrial plants with high fire or smoke risk, confined-space operations requiring emergency containment planning, and coal mine refuge installations.

We offer both permanent refuge chambers for fixed, long-term installations and temporary refuge chambers designed for short-term or mobile operations. Permanent systems are engineered for static underground locations, while temporary units provide flexibility for evolving site conditions and project-based deployments.

SomNandi Industries Advantage

In high-risk environments, safety cannot rely on basic enclosures or generic solutions. Effective emergency protection demands a fully engineered refuge system—one that is designed, manufactured, and integrated with survival as its core purpose.

Our refuge chambers are developed through an engineering-led approach that combines in-depth hazard analysis, application-specific design, and robust manufacturing practices. Each system is tailored to the operational realities of the site, ensuring reliable performance under extreme and unpredictable emergency conditions.

SomNandi provides custom-designed chamber configurations based on detailed occupancy planning, anticipated refuge duration, and space constraints. This ensures adequate life-support capacity, ergonomic internal layouts, and safe accommodation for personnel during prolonged emergencies.

Engineering designs are further adapted to site-specific conditions, including underground depth, atmospheric risks, thermal load, fire exposure, gas hazards, and structural constraints. This tailored approach ensures the refuge chamber remains functional and protective within the unique risk profile of each installation.

Constructed using heavy-duty materials and reinforced structures, SomNandi refuge chambers are built to withstand harsh industrial environments, including high temperatures, pressure fluctuations, impact forces, and corrosive conditions. Durability and long-term reliability are embedded into every stage of design and fabrication.

Beyond standalone performance, SomNandi systems are engineered for seamless integration with existing Emergency Response Plans (ERP), communication networks, ventilation systems, and disaster prevention infrastructure. This ensures the refuge chamber functions as a coordinated element of the overall safety strategy, not an isolated installation.

By combining engineering precision, manufacturing strength, and application-driven design, SomNandi Industries delivers refuge solutions that enhance survival outcomes, operational resilience, and regulatory confidence—when safety matters most.

Engineering Standards, Compliance & Safety Assurance

Refuge chambers are critical safety assets and must be engineered to meet stringent performance, reliability, and regulatory requirements. At SomNandi Industries, every refuge chamber is designed with a strong emphasis on compliance, risk mitigation, and long-term operational integrity.

Our refuge systems are developed in alignment with globally recognized mining and industrial safety principles, incorporating best practices related to airtight construction, structural resilience, life-support autonomy, and human survivability under extreme conditions. Engineering considerations include internal pressure management, gas-tight sealing, fire and explosion resistance, and controlled air quality over extended refuge durations. Each chamber undergoes rigorous design validation and quality checks to ensure dependable performance during real emergency scenarios.
