Potential consequences evolution from minor to ultimate
Direct physical
losses
Health and safety
Environmental
Reputational
damages
Pipelines [tailings
and dewatering
(pond, polishing
ponds, ditches)]
Traffic (includes
contractors and snow
removal collisions)
G4, G5, P1
From very limited
(if caught in time)
to major dam
damages and
finally dam break
(interdependent
failure of dam)
From very limited
to harming
workers (dam
break
consequences
studied in dams)
From very limited
(if caught in time)
to major
environmental
damages and
finally dam break
(interdependent
failure of dam)
Generally limited
unless failure
evolves in dam
break
Freezing (includes
deformations at flanges)
G4, G5
Sabotage/vandalism,

P4, A1, A2, A3
Corrosion and intrinsic
mechanical failures
F1
Human (communication
between mill and tailings
operation), IT

Confining
structures (and

Geotechnical/geological

G1, G6
As above with
possible “sudden
failures”.
Additionally
inadequate storage
capacity may lead
to BI, costly
system alteration
requirements
From very limited
to harming
workers and
possibly general

From very limited
to major
environmental
consequences
outside of the
perimeter
We consider that
any dam issue
would be covered
by local and
provincial media
and further, with
great reputational
damages
Construction/building

Operation, maintenance
and monitoring during
service and record
keeping, IT
