•
In case of Emergency, Who will do what:
– Maintenance Manager will remain in his office (safe heaven) and coordinate
with MCC for any further action.
– UM will remain in their offices (if located in Safe heaven) or come to nearest
Assembly area and get in touch with Operation UM for any maintenance
support required.
– Maintenance staff will stop their work safely, gathered at nearest Assembly
area and informed their supervisor about their location so that they can be
called in case of any emergency job.
