Alternate pathway defined by bollards and reflective tape.
Sufficiently skilled employees to complete task(competencies and Licences)
Adequate consultation with all relevant employees
Adequate competent supervision throughout the project

The workplace is adequately prepared for the incomingmobile crane, including where possible a clear predefinedarea/crane pad for the crane to position upon
Check and confirm exclusion areas - Barricades, witchesHats, Danger Tape, Warning Signs
Access road are available and soundly constructed withsuitable entry points to site
Crew should always inspect site prior to positioning cranein final position;
Elements to observe include
Load location and scope of lift
Location of any overhead obstructions including wires,trees, buildings, restricted airspace (i.e. near airport)
Location of any underground services and/or trenchesincluding utilities and drainage arrangements that mayaffect integrity of ground
Adequate room for rigging and erection of mobile crane
(i.e. support trucks, fly jibs) Adequate tail (counterweight/winch) swing clearance
Ability to cordon off area with suitable barricadingresources
Check slings for rips and tears and remove from service isfaults are found
Check chains, shackles, hooks and rings for cracks,
corrosion, wears, mechanism faults etc and remove fromservice if faults are found
Lifting gear/equipment inspected and tagged withappropriate monthly colour tag
Make certain personnel are sufficiently trained withappropriate certificates/ licences.

5. Locate crane inlifting position on site place timbers(pads) and setoutriggers
Crane overturning due tounstable ground conditions
Personnel being crushed byoutriggers
H
Outriggers must be positioned on a flat surface, usingtimbers or suitable material for pads to evenly distribute theload to the ground
Crane to be located within the radius for the loads beinglifted.
Outriggers should only be extended on the side where theoperator is positioned or with a suitable spotter.
Where space permits, outriggers shall always be fullyextended
Where space is limited, crane should be configured tomaximum capacity this may require the use of reducedoutriggers or on rubber; when permitted by themanufacturer
Outriggers shall always be extended to manufacturersprocedures and specifications, including the requirement tofit manual pins
All outriggers-jacks should be utilized at all time (i.e. Front
jack) Generally Standard Safe Working Load capacity charts are
based on all outriggers fully extended and set with wheelsclear of ground.
Outrigger Packing
Additional packing should always be utilized underoutrigger floats (exceptions may include engineered setupswhere other means of distributing loads are adopted)
Commonly used (steel fabricated or otherwise) OutriggerMats should carry design information and be subject toperiodic inspection
When timber packing is utilized, it should be in a pig-stypacking arrangement

Rule of Thumb formulae and calculations should beobserved;
Area (m2) = 0.65 x (Cm + L)
-------------

Cm = Total mass of crane (KN)
L = Total mass of load (KN)
V = maximum permissible bearing pressure of soil (kpa)
Follow W/H permit use appropriate attachment point &safety harness when walking along crane boom
Use an EWP or ladder for this task & follow safe workpractices
Wear correct PPE
Plant to be positioned in area clear of obstruction. roads
Traffic control in place if required
Once crane is elevated and level, a trial operation shouldbe completed by the operator; this may include
Luffing boom to high angle, and slewing 360 degrees withspotter in position purpose to review tail swing andoutrigger packing suitability
Executing dry-run where load is required to be picked upand placed Purpose to ensure crane is capable of taskand set required limits

Changes in weatherconditions
Changes in operators
Changes in ground suitability
Unauthorised person accesscrane site
Damage to crane
Injury to public
H

Continual safe operation can be aided by periodicinspection throughout the project of the following;
Outrigger Jacks Leaking oil/retraction of shaft
Outrigger Mats excessive settlement and/or sinking intoground; i.e., loadings increasing beyond estimated capacityof ground such as unknown back-filling
Outrigger Floats Cracking or cr itical damage
Evidence of water content in ground i.e. Potentialruptured pipeline
Should requirements change during operation, then crewshall re-assess and review crane capacity and widerenvironment to ensure revised work practice is within limitsand safe to continue operation
Upon completion of project, or specific stage the craneequipment and site shall be left in a secure and safe
manner
If the crane is to be left onsite;
Retract Boom, remove keys from the ignition andsecure/lock
Outriggers should be inspected prior to next use
Barricading should remain in place around the crane and
any work area deemed necessary

11. RISK ASSESSMENT MATRIXA B C D E
5 Critical Critical Critical Critical High
4 Critical Critical Critical High High
3 Critical High High Medium Medium
2 High High Medium Low Low
1 High Medium Low Low Low
Step 1 - People Consequences
5 = Fatality or Permanent Disability
4 = Lost Time Injury or Illness
3 = Restricted Duties Injury
2 = Medical Treatment Injury
1 = First Aid Injury
or Step 1 - Plant, Property, Process / Environmental Consequences
5 = More than $500K Damage or production disruption. . Catastrophic environmental impact.
4 = $100K - $500K Damage and/or production. Major environmental impact.
3 = $50K - $100K Damage and/or production disruption. Major environmental impact.
2 = $5K - $50K Damage and/or slight production disruption. Temporary environmental damage.
1 = Under $5k Damage and minimal productivity disruption. Minor environmental damage.
Step 2 Determine Probability
A = Common or frequent occurrence (daily)
B = Is known to occur or it has happened (weekly)
C = Could occur or Ive heard of it happening (monthly)
D = Not likely to occur (yearly)
E = Practically impossible (ten yearly)
Step 3 Calculate Risk
Once determining the probability and consequence, the risk level can be determined by using the matrix above. Thecategories within the matrix are categorised according to the level of risk as follows;
Critical Consider discontinuing operation
High Immediate correction required
Medium Correction needed
Low Risk is perhaps acceptable as is
