Crane Collapses onto Jaguar XKR

Graham Marshall - Saturday, December 01, 2012

This crane was being used to lift a new petrol storage tank for a service station being constructed in Gits, Belgium.

Unfortunately, the operator did not pay enough attention to the triggering-mechanism of the potential for round subsidence.

The ground was in fact, unstable, and two of the crane’s supporting legs sank into the soil causing the kinetic energy in the crane and its load to go out of control.

The resulting crane collapse incident caused this Jaguar XKR to meet an untimely end.

The Jaguar XKR was one of two cars damaged, the other being a BMW 630, when the crane fell onto the parking lot at B & D Automobiles. 

The company building the petrol station will now have to return the fuel tank to the manufacturer to check for damage to the tank. 

All in all, not a great day for safety!

Magnetic Lifting Device Safety Alert

Graham Marshall - Tuesday, October 23, 2012

Featured below is another of the latest safety alerts from APPEA showing information on a dropped object resulting from a failure to adopt a robust procedure when using a magnetic lifting device.

As with any lifting operation, it is imperative that crane operators and/or load riggers check and verify the status of slinging and rigging equipment; and that attachment methods are sound.  Furthermore, as always with any lift, no person should ever enter the "fall zone" in line-of-fire of the load which is why tag-lines of adequate length should be in use.  Read the alert for further information on this specific incident and for more information on the key learnings.

Careful with Unstable Loads

Graham Marshall - Monday, October 08, 2012

Enclosed here is a safety alert from the Marine Safety Forum regarding the dangers associated with lifting of unstable loads. 

The Safety Alert makes some good points and should be read by anyone involved in lifting operations.



Danger of Falling Scaffolding Tubes

Graham Marshall - Thursday, September 20, 2012

The dangers associated with not having, or not following proper procedures and not undertaking a "Stepback" using our unique Think 6, Look 6 hazard identification process are highlighted again by this safety alert from Woodside and APPEA.

The alert shows how a length of scaffolding tubing was allowed to fall between decks when procedures were not followed, supervision was not appropriate and Stepback was not being done.

Thankfully no one was harmed during this high-potential incident so luck was on the side of Woodside today.

Without a good use of Think 6, Look 6, they might not be so lucky next time.

Woodside Pedestal Crane Failure

Graham Marshall - Thursday, September 13, 2012

Here is a safety alert from APPEA regarding a pedestal crane failure involving Woodside Energy in Australia. 

The safety alert highlights the need to perform preventative maintenace checks on all cranes at regular periods.

Safely Operating Extendible Equipment Under Powerlines

Graham Marshall - Thursday, August 02, 2012

Working with mobile equipment below powerlines can be inherently hazardous and requires very good planning.

A Job Safety Analysis (JSA) should always be prepared whenever mobile equipment is to be used below overhead powerlines.

Enclosed here is a free example JSA for use in helping to plan work with extendible mobile equipment. 

The JSA is a "printer-proof" example of the types of JSA which are available in our award-winning JSA Manual.

The manual has an additional 46 JSAs for a range of higher-risk jobs and is ideal for supervisors and managers working in mining, construction, transportation, utilities, shipping, manufacturing and oil and gas.

Managing Hazards During Construction

Graham Marshall - Wednesday, July 25, 2012

According to the WA Department of Mines and Petroleum, there is more than AUD $180 billion worth of resource projects in development in Western Australia.

These mega-projects are expected to create more than 50,000 new construction jobs.

But the construction phase is a dangerous time for workers.

Accident statistics for the minerals sector have shown a consistently high proportion of fatalities and injuries associated with construction activities.

This is mainly because construction workers undertake such a high-number of potentially higher-risk tasks and jobs.  Examples of these higher-risk jobs include:

• Lots of driving of light-vehicles and heavier mobile-equipment;

• Scaffolding;

• Tilt up or precast construction;

• Electrical work;

• Working at height;

• Using cranes;

• Work in excavations;

• Working with hazardous substances; and

• Using elevated work platforms (EWPs).

The requirement to perform such a high number of potentially higher-risk jobs is also then compounded by other management issues.  These include:

• Tight deadlines for project completion;

• An inexperienced workforce;

• Large numbers of workers concentrated in relatively small area's; and

• The potential for poor contractor management systems.

Risk management during the construction phase of project development has always been a priority target for  the Risk Management Tool Box.

For almost 15-years we've been reviewing and revising customer management systems to improve compliance capacity and capabilities, and add value by raising awareness of the hazard and risk management process.

Our experience and expertise during the construction phase is focused on the following:

• Improving the internal systems and processes deployed to manage risk by our customers, especially focussed on procedures, job safety analysis and appropriate risk assessments and planning;

• Empowering construction workers with the required safety competency needed to effectively promote OHS requirements during construction;

• Helping workers, supervisors and managers to identify and manage common construction hazards; and

• Providing behaviour-based hazard observation programs to ensure everyone is involved in managing the hazards they face at work.

JHA for Work Under Power Lines

Graham Marshall - Tuesday, July 10, 2012

Enclosed here is a free Job Safety Analysis for use when work is being done below over-head live electrical lines.

The free JSA shows the format of all the other JSAs which are included in our JSA Manual

You'll see the JSA highlights the hazards, triggers, incidents, consequences, prevention controls and escalation controls which may be required when working underneath live lines.

The JSA also highlights the various risk management responsibilities when co-ordinating such work tasks.

Our award-winning JSA Manual is available for purchase from the website.  Simply click this link to find out more.



Sling Inspection Audit Checklist

Graham Marshall - Sunday, June 17, 2012

Whenever any type of lifting sling is to be used for rigging-up a load, whether it be a nylon or polyester sling, or a chain or wire rope sling, the sling should always be inspected for damage and removed from service if there is any doubt about its capacity to sustain the lift.

At the Risk Tool Box, we recommend that a systematic approach to sling inspections be adopted, and the checklist below can be used to audit and verify that inspections are being done as part of a rigging procedure.

For further information about our approach to procedure development and audit checklists against procedures, feel free to get in touch.

Removal Criteria for Wire Mesh Slings

Graham Marshall - Saturday, June 16, 2012

Prior to the start of any lifting activity involving the use of a wire mesh sling, the sling should be inspected for damaged, and removed from service if conditions such as the following are present:

  • Missing or illegible sling identification;
  • Broken weld or a broken brazed joint along the sling edge;
  • Broken wire in any part of the mesh;
  • Reduction in wire diameter of 25 per cent due to abrasion or 15 per cent due to corrosion;
  • Lack of flexibility due to distortion of the mesh;
  • Distortion of the choker fitting so the depth of the slot is increased by more that 10 per cent;
  • Distortion of either end fitting so the width of the eye opening is decreased by more than 10 per cent;
  • A 15 per cent reduction of the original cross-sectional area of any point around the hook opening of the end fitting;
  • Visible distortion of either end fitting out of its plane;
  • Cracked end fitting;
  • Slings in which the spirals are locked or without free articulation shall not be used;
  • Fittings that are pitted, corroded, cracked, bent, twisted, gouged, or broken;
  • Other conditions, including visible damage, that cause doubt as to the continued safe use of the sling; and
  • If in doubt – remove the sling from service.
