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 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”

Safety begins to converge to focus on the individual

If further information about the increasing inter-relationships between psychosocial health and physical health, organisational culture and a worker’s mental health was needed, a new study from Sweden provides convincing evidence.

The research, a study of 81 research projects into the links between psychosocial factors and musculoskeletal disorders, was reported in by Eurofound on 10 September 2010. It found, among other issues that

“… The link between an unfavourable psychosocial environment and the prevalence of MSDs is well established, with a number of studies demonstrating that high stress at work is connected to increased risk of developing a musculoskeletal disorder.

What is the OHS “public interest”?

On 7 May 2010 Judge Lacava of the County Court of Victoria increased the $A25,000 fine applied to A Bending Company to $A75,000.

WorkSafe’s Acting Director for Health and Safety, Stan Krpan, said in a media release:

“The fact that the Director of Public Prosecutions [DPP] found the original penalty inadequate, and the increase in the fine on appeal, demonstrates the courts’ attitude towards health and safety offences.”

The DPP made the appeal to the County Court after a request for review of the original fine was made by WorkSafe Victoria. According to the judge’s decision (not yet available online):

“The appeal by the Director is made pursuant to section 84 of the Magistrates’ Court Act 1989. The section gives the Director the power to appeal to this Court “if satisfied that an appeal should be brought in the public interest“.” [emphasis added]

So how was the public interest served by increasing the fine by $A50,000? Continue reading “What is the OHS “public interest”?”

Ergonomics of quad bikes – new research

While the New Zealand government is investigating agricultural safety issues, researchers from the University of Otago have looked at the ergonomic issues associated with the loss of control (LOC) of quad bikes by drivers.

According to a University of Otago media release, researchers Dr Stephan Milosavljevic and Dr Allan Carman published a paper in the current edition of Ergonomics. The researchers

“….set out to analyse the driving behaviour of people who regularly use quad bikes, recognising a need to find out why people lose control of them so frequently.

Of the 30 male rural workers and farmers studied, 19 of them, or 63 percent, had experienced loss of control on a quad bike. They were in their mid 40s on average, and about eight to nine years younger and less experienced than those who did not lose control. Continue reading “Ergonomics of quad bikes – new research”

Safety professionals must understand RTW in order to avoid unnecessary costs

The rationale for the Australian government’s evangelism of harmonisation is the reduction of “red-tape” on the logic, or assumption, that business costs will also be reduced. Dr Mary Wyatt, according to a report on ABC News Online, says that cost reductions may be possible be reducing over-servicing of injured workers.

Dr Wyatt says:

“We have an increasing focus on the medicine, and we have lots of scans that tell us there are things wrong with our bodies, and then when those scans are done it’s often labelled as a serious problem, and then the worker gets worried and we often go off on a tangent..” Continue reading “Safety professionals must understand RTW in order to avoid unnecessary costs”

If laptop design is hazardous, what does this say about the iPad?

Recently SafetyAtWorkBlog received some promotional material from a laptop accessory supplier, ErgoAustralia, which stated that laptops may be “the RSI of this decade especially for the growing bones and muscles of our children”. The aim of the information was to show how accessories can reduce the risk of using laptop computers.

There is no doubt that this is so. This blog is often written in a cafe through a fold away keyboard and back at the office, the laptop sits on a stand with a wireless keyboard and mouse but the laptop is not the principal PC on which work is performed. That is a desktop PC.

When laptops are the only computer option and the work tasks rely on laptops, the complications and hazards occur.

Rick Clancy of ErgoAustralia provided the following quotes in support of the dangers of laptops:

Alan Hedge from Cornell University says the following “Guidelines for laptop use are more difficult because laptop design inherently is problematic – Continue reading “If laptop design is hazardous, what does this say about the iPad?”
