Strata Safety Products - Emergency Refuge Chambers, CO2 Scrubbing Systems, Communications and Tracking, and Cap Lamps

Strata Safety Products is a worldwide leading provider of emergency refuge chambers and breathing air systems.

Communications and tracking system for underground mining

Strata CommTrac is a wireless, battery-powered communications and tracking system for underground mining. The CommTrac mesh network is a self-forming, self-healing system that requires no hardwired backbone or external power source. CommTrac provides two-way text messaging and real-time location tracking to within 50 feet mine-wide. CommTrac remains in operation post-accident.

Asset tracking

CommTrac also provides the ability to track equipment and machinery underground. Operators can monitor ongoing operations and measure production.

Atmospheric monitoring

Strata incorporates fixed gas detection systems into CommTrac networks to provide wireless atmospheric monitoring. The data collected by the atmospheric monitoring devices is continuously transmitted to the mine's central office via CommTrac and displayed on a graphical user interface.

StrataWifi

StrataWiFi brings access to communications and productivity tools underground that before were only available on the surface. This includes Voice-Over-IP (VoIP) phone service and computer access to company networks and the Internet via 802.11 standard devices.

To keep costs low, StrataWiFi only uses intrinsically safe access points in the working areas of the mine where they are required. Less expensive, non-intrinsically safe access points are used wherever possible.

Post-accident, through-the-earth communications system

Strata Worldwide's proprietary post-accident through-the-earth communications system that enables two-way text communications between miners trapped underground and the surface. The system reaches up to 300 feet directly through the earth. Leveraging CommTrac wireless networks, messages can be sent directly to and from individual miners mine-wide. Strata ThroughEarth system does not utilize large loop antennas and is battery powered.

Mine refuge chambers

Strata Safety Products is a worldwide leading provider of emergency refuge chambers and breathing air systems.

Portable, inflatable refuge chamber: the Strata Safety Fresh Air Bay is a powerless inflatable refuge chamber constructed from durable, flame-retardant material. It is stored in an explosion-resistant steel skid until deployment. In an emergency, the Bay is inflated directly from the skid using compressed air cylinders and is filled with breathable air as it inflates. Oxygen cylinders and an air powered, active CO2 scrubbing system maintain breathable air.

An airlock compartment at the entrance and a purge air system, minimise contaminants polluting the air as occupants enter.

Steel walk-in refuge chamber: Strata Safety Products steel walk-in refuge chambers connect to the main power and air sources of the mine where they can operate indefinitely. If mains power is lost, the system switches to a battery back-up. If mains air is lost, chambers are equipped with oxygen cylinders and an active carbon dioxide scrubber.

Chambers are equipped with 24V lighting and an optional air-conditioning unit.

All chambers include an airlock compartment and optional purge air, padded seating, storage, food, water, a gas monitor, first aid and a toilet. All are manufactured with a skid base, fork-lift guides and lifting facilities. Wheel and hitch packages are optional.

Steel walk-in chambers for coal mines: for the unique requirements of the coal mining environment, Strata Safety designed a completely powerless walk-in chamber. This unit is standalone with air and other supplies to last 96 hours. The chamber is equipped with compressed air cylinders, oxygen cylinders and an air-powered CO2 scrubber. Lighting is provided by approved flashlights and cooling as needed.

All chambers include an airlock compartment and optional purge air, padded seating, storage, food, water, a gas monitor, first aid and a toilet. All are manufactured with a skid base, fork-lift guides and lifting facilities. Wheel and hitch packages are optional.

Strata Safe Rooms: the Strata Safe Room is a pre-constructed refuge room, designed to provide protection and breathable air to miners trapped underground in emergency situations. Strata Safe Rooms come equipped with Modular Kits, including air conditioning, breathable air, storage, and other essential supplies.

Cordless LED mining cap lamp

The Northern Light Polaris all-in-one, cordless cap lamp is an LED headpiece only with optics designed for the mining environment. The primary LED lamp produces 3,500 lux output. The high-capacity lithium-ion battery and LED light are housed in a single, impact, dust and water-resistant plastic enclosure. Polaris is MSHA approved.
