ISSUES/HAZARDS & RECOMMENDATIONS FOR CRANE SETUP

The JHA study minutes are presented in the following pages. The table presents the task step, identified issue or hazard, initial risk, controls(where necessary), residual risk, to be actioned by, and completion sign off.

Sufficiently skilled employees to complete task(competencies and Licences)

Adequate consultation with all relevant employees

Adequate competent supervision throughout the project

Proper planning for equipment required for the task Site & work area inductions compulsory for all personnel

Desired setup area should also be level, unless priorconsultation has been made with the supplier of the crane

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)

-------------

V

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

9. Re-assessingSituation throughoutjob

10.Packing up and/or

leaving crane onsite

Changes in weatherconditions

Changes in operators

Changes in ground suitability

Unauthorised person accesscrane site

Damage to crane

Injury to public

H

M

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
