The implementation of this module contributes to mitigating the following risks:

a) compliance with legislation (LOLER, PUWER, COSHH, HASAWA);

b) damage to assets, e.g. OTM's incorrectly stowed equipment hitting a passing train during ALO operation;

c) runaway/failure to stop on demand, e.g. OTM running away on a gradient;

d) derailment, e.g. OTM being loaded incorrectly; and

e) staff injuries, e.g. Operator being trapped between machine and infrastructure or machine and machine.
