The apparatus includes a proximity sensing portion disposed in the explosion-proof housing having a magnetic field source which produces a magnetic field that is used to sense a location of the miner relative to the machine. The apparatus includes a wireless communication portion disposed in the explosion-proof housing through which the magnetic field produced by the magnetic field source is changed remotely and wirelessly from outside the explosion-proof housing. A method for protecting a miner from injury by a machine.
