As an Association that
represents the interests of Victorian quarry owners and
employees, the CMPA
recognises the numerous
hazards faced by those employed in the extractive
industry. In response, the
CMPA invited the
Victorian quarrying industry to its second
Haza rd an d R i sk
Identification Workshop
in March.
Following on from the
Drilling Workshop in
2004 , the second workshop focused on
Mobile Plant and Equipment in
order to identify the hazards
involved and how, with the present technology, some of
these can be controlled.
On March 9 2005 over 70 emp loyers , emp loyees ,
regulators, educators and
manufacturers gathered in
Bendigo to meet the challenge.
After many discussions and a
site visit to either Allstone
Quarry or Mawson’s Lake Cooper Quarry, the groups
identified the following hazards
and controls.
To best incorporate these into
your business’ Occupational Health & Safety Management
systems, the following should
be undertaken.
It is recommended that a Job
Safety Analysis be conducted
at your site. This would need
to involve all persons involved
in mobile plant operations -
for example, the Quarry Manager, Operators, their
assistants and others. How to
conduct a JSA is thoroughly
covered through the Conduct Local Risk Control training
program.
Now that your company
has carried out a JSA, did
you identify any hazards
that were not listed on
the following pages? If so, drop the CMPA a line so
that others can benefit
from your experience.
When selecting controls,
always remember to
select in the following order:
1. Elimination
2. Substitution
3. Engineering
4. Administrative
5. PPE

Incident: A dump truck was being
loaded with overburden adjacent to an 18m highwall with a major fault zone.
A failure occurred with material falling
against and around the front of the
driver’s side, preventing the truck
from moving. The driver scrambled from the cabin uninjured. The toe and
crest area in the vicinity were
barricaded off and observed. About 30
minutes later a major fall completely
buried the truck.
Cause:
Failure to identify the full
potential of the hazard and thus
properly assess risk
Change in strategy without any
formal re-assessment of the risk
Comments: Due to the nature of
the overburden gradual failure of
sections of the pit walls was expected,
accepted and access controlled.
Regular inspections had not identified any change in geotechnical conditions.
The driver was placed in a vulnerable
position.
Recommendations:
Apply the risk management
process to all activities in the
vicinity of highwalls to ensure
adequate controls are in place
Ensure adequate geotechnical
analysis is carried out and incorporated into pit design and
extraction planning to minimise
the risk of wall failure and also
applied to any changes to ensure
hazards are not created that can destabilise the integrity of walls
Develop and apply monitoring
processes for walls that require a
response when changes are
detected to ensure the risk is at
an acceptable level.

HazardsIn Mobile Plant
Operations
Incident: An operator fell more than 2
metres from a bulldozer to the ground and sustained multiple injuries. The
incident had the potential to result in a
fatality.
Findings: The operator had just refuelled the dozer and was attempting
to climb down to the ground to return
the nozzle to the fuel tank.
He tried but failed to grab a safety rail and fell from a platform on the side of
the dozer cabin near the fuel tank. He
landed on the top of the brick wall
surrounding the diesel tanks and sustained concussion, lacerations to his
arms and legs, a bruised kidney and a
fractured rib.
The following factors contributed to the
incident:
The incident occurred in darkness;
The conditions were wet and
muddy;
The employer had not identified
access to and from the dozer fuel
tank as being a hazard; and
The supplier of the machine had
not provided sufficient controls to prevent falling from height.
Comment: The occupational health
and safety legislation in Victoria requires
quarry employers and the designers,
manufacturers and suppliers of mobile plant, to identify and control hazards
associated with the operation of plant.
Despite this, accidents caused by access
to and from mobile plant continue to represent a large proportion of the total
lost time injuries in mines and quarries.
Numerous improvements have been
made in the design of the means of access to and from mobile plant cabins
in recent years. However, equipment is
not always supplied with these
improvements as in some cases they are optional and require additional cost.
Access to and from mobile plant for
servicing and fuelling constitutes
additional hazards. Some of these hazards can also be engineered out.

Case Study 3: Dump Truck Rollover
Incident: The Department
carried out an investigation into another truck rollover
involving a 50 tonne rear
dumper. On this occasion the
truck rolled over after running into a stockpile of
rock on a bench in a quarry.
The operator sustained
serous injuries and was hospitalised for over a week.
The incident had the potential
to result in a fatality.
Findings: The operator drove the loaded truck
towards the haul road in
daylight. The truck veered off
course and into the stockpile of rock, causing the truck to
roll onto its side. The
operator fell a distance of
approximately 3 metres through the passenger door
opening of the cabin to the
ground. He sustained severe
concuss ion , a ser ious laceration to his head and
extensive burns to his leg
from the exhaust. The truck
was a s se s sed to be mechanically sound prior to
the incident. The haul road
was in good condition and the weather conditions were fine.
The site’s safe operating
procedure requires seat belts
to be worn. The operator was inducted, trained,
experienced and deemed
competent by an independent
assessor, however, was not wearing a seat belt at the
time of the incident.
Comments:
The Occupational Health
and Safety Act 1985 requires employees to
comp ly w i th sa fe
operating procedures
The operator could have
avoided injuries by wearing a
seat belt
Recommendations and
Preventative Action:
Employees must follow
s a f e o p e r a t i n g
procedures, remain on
haul roads and wear seat
belts when operating mobile equipment.
Designers of plant are
required to eliminate
risk as far as is
p r a c t i c a b l e . Consideration should be
given to design out this
hazard by immobilising
p l an t o r warn in g operators when seat
belts are not buckled.
Significant Incident Report #8-
2005 supplied by Victorian DPI
Case Study 2: Fall from Dozer Continued
For example, where possible all servicing
and refuelling should be performed from the ground.
Where improvements in the design to
the means of access to and from mobile
plant are not practicable, employers must rely on procedures and training to
reduce the likelihood of incidents
occurring.
R e c o m m e n d a t i o n s a n d preventative action: Employers and
the designers, manufacturers and
suppliers of mobile plant must ensure
that the hazards associated with access
to and from mobile plant cabins and servicing and refuelling locations are
eliminated, or minimised as far as is
practicable.
Employers must ensure that refuelling and servicing of mobile plant is
performed in daylight or with sufficient
auxiliary lighting.
For further guidance refer to the Occupational Health and Safety Act,
Occupational Health and Safety (Plant)
Regulations, Occupational Health and
Safety (Prevention of Falls) Regulations.
Note: The supplier of the above bulldozer proposes to design out this
hazard by modifying their new
equipment range to enable refuelling to
be performed at ground level.
Significant Incident Report #2-2005
supplied by Victorian DPI
* Following this incident, the dozer in
question was converted to fast fill to enable refuelling to occur at ground level.

Case Study 4: Rollover of Rear Dump Truck
Incident: An access ramp
was being constructed in an open cut mine using a truck
and shovel operation. While
reversing the first load of the
night shift to a dump area, an operator of a rear dump
truck drove over the rill
[bund wall] on the edge of
the dump resulting in the truck rolling and coming to
rest at the bottom of a 15m
drop. As the truck rolled
down the embankment, a rock entered the cab through
the window on the driver’s
side and smashed a hole
through the passenger side window when the truck came
to rest. The operator who
was restrained by his seat
belt, received no injuries.
Cause:
The height and size of
the rill was inadequate
and not identified as a
risk by the operators
The rill was constructed
of soft material that was unconsolidated
Lack of handover
between shifts led to
hazards in the workplace
not being communicated The dump face was not
square or detected while
reversing towards the
tip
The position of the
lighting plant meant that
the truck operator could not turn normally and
therefore was unable to
drive close to the dump
area to observe any potential hazards
The dozer operator on
night shift did not
inspect his work area for hazards prior to allowing
the trucks to commence
operating in the area
The dozer operator on
the previous shift had not worked to the
mine’s standard for a
dump area by allowing
the dump face to become misaligned

Recommendations:
D e v e l o p / r e v i e w
p r o c e d u r e s a n d standards for dump
design and set-up
particularly during hours
o f darkness . The standards must include
widths and grades,
