Using a combination of the event escalation and damage limitation, Fig. 20.12
shows how minor events can gradually entail serious environmental damage, major
property damage, fatalities, or significant loss of production capacity.
If we examine Fig. 20.13, we can observe three layers of barriers, which can help
in minimising significant losses to the infrastructure provider. These barrier layers
should be strong, without being too rigid, to exercise a rigorous control on practices
which might seem prone to entail event escalation.
The maintenance process can be represented in four phases, explained in
Table 20.2.
Figure 20.14 below shows these four phases.
