Strata Emergency Refuge Chamber for Metal/Non-Metal Mining and other underground construction applications
Strata Emergency Refuge Chambers are complete safety systems designed to provide immediate refuge and breathable air in the event that air quality in the working environment becomes compromised. They are intended to be an alternative option when escape is not possible.
Strata Safety Refuge Chamber for Metal/Non-Metal Mines.
Strata's refuge chambers are purpose built to customer specifications and constructed to withstand harsh underground mining environments. They are welded to be airtight and provide an immediate source of breathable air upon entry.
Primary Operation of Refuge Chambers
Strata Refuge Chambers are designed to attach to the mine’s main compressor air lines and electrical power sources for an indefinite supply of breathable air and power. The mine air passes through a specialized filtration system to perform a complete cleansing by removing any taste or odors and preventing CO2 and heat build-up. The entrance of air creates a positive pressure throughout the chamber and a non-return valve controls the pressure. Power attaches to operate the lights, siren, carbon dioxide scrubber, optional air conditioner and optional atmospheric monitoring system.
Back-up Operation of Refuge Chambers
Strata Mine Refuge Chambers are equipped with a standard 48 hours of battery and air back-up supplies. These systems are upgradeable to 96 hrs. Backup power is a bank of fully automatic 24-volt batteries at the rear of the chamber and backup air is provided by on-board oxygen cylinders and an active soda lime carbon dioxide scrubber.
Technical advancements of the Strata Emergency Refuge Chambers include:
- Robust Construction-Engineered and constructed to customer specifications.
- Quality Air Supply System- High quality air filtration system purifies mine air. Backup air supply provides at least 48 hours of breathable air.
- CO2 Scrubber System- Active CO2 Scrubber removes carbon dioxide using soda lime chemicals.
- Air Conditioning- Optional DC Split Level air conditioner.
- Standard & Custom Sizes-Strata Safety Refuge Chambers are available in standard & custom
sizes to meet individual customer needs. This includes custom length and heights of the structure. - Air-Tight Rugged Design-Withstand rough environments and provide immediate breathable air upon entry.
- AirLock Entry-Sectioned off area to help minimize the entrance of air contaminants into the main chamber. Optional purge air system can be used to flush the air in the airlock prior to occupants' entrance into the chamber
- 24-Volt Lighting-Internal 24V LED lighting system.
- Drinking Water & Food-Includes food & drinking water in storage compartments under the seats..
- Moves Readily-Built-in fork lift guides, lifting facility and skid base assist with moving & relocating the refuge chamber. Optional wheel and tow hitch packages available.
- Lavatory-Chemical toilet in a private compartment.
- Cushioned Seating & Storage Areas-Cushioned seating for all occupants & storage areas for additional supplies/equipment.
- Fire Extinguisher-20 lb/9 kg fire extinguisher
- Escape Hatch-Built-in emergency escape hatch.
- External Location Lights-External location lights & warning siren.
Strata Refuge Chamber Wheel and Tow Hitch Package
In order to assist moving the chambers into and around the mines and in restrictive areas, Strata Safety has engineered a robust wheel and tow hitch package to be added during construction of the unit or retrofitted later. These additions will significantly reduce wear and tear on the unit during movement. The wheels are made of solid, highly resistant rubber (non-air filled).

Customization
The dimensions of the Strata refuge chambers can be customized according to specific customer requirements. A few examples include:
- Tunneling (reduced width)
- Low Profile mines (reduced height)
- Powerless (air-powered and MSHA approved components)
- Compact and mobile (small, lightweight and equipped with wheels)
Atmospheric Monitoring
A Programmable Logic Controller (PLC) can be installed to continuously monitor the chamber’s internal and external atmospheric conditions. The system monitors the levels of O2, CO, CO2 and temperature and readings are displayed on a control panel mounted in the chamber. Live video feed enables surface personnel to monitor the occupants of the chamber in real time.
