About
The BG 4 Benching Trainer software is a supplemental tool used to assist mine rescue personnel in learning and retaining knowledge of the process of benching (inspecting, assembling, and testing) a Draeger BG 4 breathing apparatus. The training places the user in a 3D interactive environment where they can visually inspect the individual parts of a BG 4 breathing apparatus, assemble the parts, and test the assembled unit with the virtual RZ tester.
