Independent research into quad bike ROPS safety

In early 2009, Australian engineer, Shane Richardson, completed his thesis into the “Performance Criteria For Effective Structural Rollover Protective Systems For Light Passenger Vehicles”.  Part of his thesis included an evaluation of the New Zealand Department of Labour’s ROPS guidelines for ATVs or quad bikes.

Richardson points out that the guidelines have strong similarities to the Australian Standard for protective Structures on Earth-moving Machinery (AS2294) although quad bikes may tipover or undergo a multi-directional tumble, the latter action is not one considered by AS 2294.  Richardson believed that the earth-moving machinery “origin” of many of the basic concepts and calculations in the NZ DoL guidelines made them useful but inadequate.

NZ Farmers rep enters quad bike safety debate

An opinion piece was published in the New Zealand Herald on 12 January 2011 concerning quad bikes.  There are several points raised by Donald Aubrey, vice-president of Federated Farmers and chairman of the Agricultural Health and Safety Council that can be disputed.

“In the hands of the untrained or the over-confident they can be deadly. And quad bike safety is far from being a problem exclusive to the agricultural sector.”

From the outset Aubrey’s position is clear, the problem with quad bike safet is not design-related, it is lack of training and over-confidence.  Training for quad bike riding has existed for many years and injuries continue to occur.  At what point should more effective controls be introduced?

NZ Coroner presses for changes in quad bike safety

One of New Zealand’s coroners, Ian Smith, has set a safety challenge to the OHS regulatory and quad bike distributors.  In the coronial findings (not available online) into the 2008 death of 21-year-old beekeeper, Jody Santos, Coroner Smith has recommended to the Ministers for Transport and Labour:

“The Court endorses the new educational and enforcement programme being proposed by the Department of Labour, but considers that both Ministries undertake an immediate investigation to consider the mandatory installation of:

(i) The compulsory wearing of helmets when operating ATVs in any circumstances; and

(ii) The installation of a roll bar on all A TVs/quad bikes; and

(iii) The installation of lap belts on all ATVs/quad bikes.”

The Department of Labour (DoL) specifically requested that the Coroner remove the mandatory installation recommendation.   Continue reading “NZ Coroner presses for changes in quad bike safety”

Quad bike safety issues continue with no end in sight

SafetyAtWorkBlog has been following the discussions about safety of all-terrain vehicles and quad bikes for some time.  This is because the use of these vehicles encapsulate so many of the issues that workplace safety needs to deal with:

  • Safe design
  • Personal protective equipment
  • Hierarchy of controls
  • The line between private activity and work activity
  • Personal responsibility
  • The “nanny state”
  • Regulatory safety guidance
  • Industry-based codes of practice

On 19 December 2010, the New Zealand Sunday Star Times ran a feature article on quad bikes, written by Amanda Cropp (I can’t find the article online but please send a link if you can) entitled “Risky Business”.  The article is a fair summation of many of the perspectives and attitudes to quad bike safety.

For those readers who like statistics, Cropp writes that

“The annual ACC [Accident Compensation Corporation] bill for quad bike-related injuries is around $7 million, and Hobbs’ claim was among 2533 in 2009, a sizeable increase on the 457 new claims accepted in 2000.” [link added] Continue reading “Quad bike safety issues continue with no end in sight”

West Australian farmer found dead under his quadbike

WorkSafe WA has reported on a quad-bike related death of a 68-year-old man in the evening of 12 December 2010.  Details are scarce as OHS inspectors have only been able to attend the scene this morning.

The WorkSafe media release (soon to be available online) states:

“WorkSafe is investigating the work-related death of a 68-year-old man on a farm at Crooked Brook, near Dardanup south of Bunbury, last night.
The farmer was believed to have left his house to move cows from one paddock to another.  When he did not return, a family member went to look for him and found him under an upturned quad bike.”

Details of the type of terrain, safety features of the quad bike and the type of PPE on site were not available at the time of writing. Continue reading “West Australian farmer found dead under his quadbike”

Of stunning, short-lived cactus flowers and quad bikes

The smoke from the mine:

It has been a frighteningly bad month in the mining industry internationally.  OHS meetings I attended during this period have been hushed as a result of the New Zealand tragedies.  Discussions about OHS have become more pertinent and more accurate – for the time being.  But this, like stunning but short-lived cactus flowers, will quickly disappear.

Because I’ve had close involvement with the Beaconsfield Gold Mine rockfall that killed Larry Knight, and years earlier with the Esso Longford explosions and fires in Victoria, the CrossCity tunnel fatality in Sydney… and many other tragedies or near misses, such events, like a sudden cramp, re-focus my thinking on current issues.  Another OHS failure that we didn’t stop.

Quad bike safety:

One such issue I’ve been involved in for some time has been the quad bike safety issue. The fatality statistics I have on these machines in Australia show that over the last 10 years 13 people (on average) are killed per year.  130 people, most of whom, the industry will have you believe, were ‘mis-users’ of the machines (see below).  The trend is up not down.

I have just resigned from the TransTasman Quad Bike safety committee created by the regulators last year.   The OHS and quad bike interest group in the community may be interested in some of the difficulties I see with the current work on this issue.

The obvious and useless in practice:

I think a much greater degree of transparency and openness – including a high level public conference – ought to take place.  And neither the regulators nor industry will be interested in that; Continue reading “Of stunning, short-lived cactus flowers and quad bikes”

Computer simulations of quad bike risks do not reflect reality

Guest contributor David Robertson discusses the  differences between risk simulations and real risk data in relation to quad bike safety:

“The motion picture blockbuster “Avatar”, for the time we are in the cinema, would have us believe that Sam Worthington can turn into a giant blue man on a faraway planet.  James Cameron used computers to deliver us this illusion. In science (and particularly with safety) we must be able to distinguish between computers that are valuable tools and computers that don’t represent reality.  Dynamic Research, Inc.(DRI) chose 113 actual quad bike (ATV) accidents to simulate in a computer model.

The first table below shows the injuries DRI record as what really happened from all the 113 cases, but represented as approximate normalized injury cost (ANIC)*.   When DRI’s computer runs the same cases, one would expect a similar result.  The results are shown in the second table (ANIC), note the scale on the left has had to be changed (table 2 should be about 10 times taller if the same scale in table 1 was used) because head injuries rose from 360 points to well over 3000. Equally astonishingly is that abdomen injuries have vanished altogether and chest injuries dropped from 266 to a next to nothing (23). Asphyxiation was not even included in the computer model.
