Lost time injury (LTI): A work injury that results in an absence from
work for at least one full day or shift any time after the day or shift on
which the injury occurred
Serious injury: A lost time injury that results in the injured person
being disabled for a period of two weeks or more
Minor injury: A lost time injury that results in the injured person being
disabled for a period of less than two weeks
Disabling injury (DI): Work injury (not LTI) that results in injured
person being unable to perform his or her ordinary occupation (regular
job) any time after the day or shift on which the injury occurred,
regardless of whether or not the person is rostered to work, and where
alternative or light duties are performed or hours are restricted

Fatal accidents 2009-10
• A service crewman employed at an underground gold mine was
fatally injured when he fell through an ore pass grizzly onto the
muck pile 38 metres below. He had been attempting to cover
the grizzly to prevent dust coming out of the ore pass system
during tipping operations from higher levels in the mine. His
body was discovered in the early hours of the morning.

Fatal accidents 2009-10 cont.
• An employee of a high-pressure water de-scaling contractor
working at an alumina refinery was fatally injured in the early
hours of the morning when he fell at least 25 metres inside a
process vessel at height and struck the ground. The vessel
comprised two separate but adjoining chambers. The worker
apparently fell through an open manhole into the lower chamber
of the vessel and then to the ground via a discharge chute.

Fatal accidents 2009-10 cont.
• An underground loader operator employed at an underground
nickel mine was fatally injured when he drove a load-haul-dump
(LHD) machine into an open stope void and fell about 24
metres.
