What is the purpose of training underground?
To provide Awareness level training in the areas of general confined spaces, specifically Abandoned Mines, certain Tunnels, and as a prerequisite for Cave SAR training.
What is the definition of something that’s intrinsically safe for underground use?
electrical design (for comms or other signal devices) that will not create a spark if external wires touch, metal strikes the device, or another device’s wires touch the device
What items are not intrinsically safe for underground use?
Typical headlamps & cell phones are not intrinsically safe so if there’s explosive/flammable conditions, they must be turned off or put in an explosion-proof case
What devices are permissible for use underground?
A device that has been cleared by MSHA (Mine Safety & Health Admin)
What is the definition of a lower explosive limit LEL?
a percentage of flammable gas concentration, if below this limit, the gas will not explode in air, if above this limit the gas can explode when exposed to air
When should gas monitoring equipment be used?
For ALL underground operations
Can CAMRA enter suspected HazMat environments?
No, a confined space HazMat team will be called and CAMRA will provide support
What should be done if unsafe O2 or gas readings are observed
Do not continue. Exit mine/cave
What should be done in case of loss of communication with surface team
Do not continue. Recover communications immediately
