4.3 Transition from the M-20 to EBA 6.5
It is critical that the overall escape strategy is complete and accounts for
mining personnel reaching the surface. If the escape time is greater than
the duration of the self-rescuer, provision must be made to further protect
the mining personnel. Storing the Ocenco, Incorporated EBA 6.5 within
reach of the M-20 allows an extension of escape time.
Transition from the M-20 to EBA 6.5 should first be illustrated by use of the
training video and then practiced,
“hands on”, by the trainees. The training
video shows the donning of the M-20 and then shows the following
transition to the EBA 6.5:
