Strata’s Metal/Non-Metal Refuge Chamber Provides a Safe Haven for Trapped Miners
The Strata Safety Metal/Non-Metal Refuge Chamber attaches to the mine’s main air lines and power source for an indefinite supply of fresh air and power. The power source operates the lights, optional air conditioning and the CO2 Scrubber. A specialized filtration system performs a complete cleansing of the air as it enters the chamber. This removes any taste or odors and prevents CO2 and heat build-up.
Metal/Non-Metal Refuge Chambers are also equipped with a standard 48 hours of battery back-up and a back-up air supply.. These systems are upgradeable to 96 hrs. The back-up air supply is provided by oxygen cylinders and an active soda lime scrubber. This innovative, CO2 Scrubber is powered by mine power or the chambers battery backup. An optional air conditioning unit is used to maintain safe temperature and humidity levels inside the chamber. The Strata Safety Refuge Chamber is delivered with water, food and a first aid kit neatly stowed on-board.

Strata Safety Refuge Chamber Wheel and 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 hitch package to be added during construction of the unit or retrofitted later. These additions will significantly reduce wear and tear during movement.
Metal/Non-Metal Refuge Chamber with Wheel and Hitch Package
Each chamber is fitted with four smooth, solid rubber wheels and six wheel mounts (three on each side). The choice of wheel mountings is relevant to the direction the chamber will be pulled. Placing the wheels next to each other on each side facilitates easier turning and placing the wheels on the end most mounts allows the Chamber to balance itself. The wheel location can be changed while underground. Standard ground clearance is 5 ½”. Custom set up to increase or decrease ground clearance is available.
The chamber hitch is a removable drawbar supplied at varying lengths. The hitch can be used on either end of the chamber to facilitate pulling in either direction.
