Statistics traps and a soft “warning”

In the Sydney Morning Herald on 17 July 2009, Kirsty Needham reported

“Total injuries rose by 2339 (2 per cent) to 142,542”

The media release from the Minister, Joe Tripodi on 15 July pointed out that the injury rate actually fell by 2%. An important point for the article and an error that has already been pointed out to Kirsty by others in New South Wales. Sadly, the error is understandable to those of us who dip into the statistical reports. (SafetyAtWorkBlog reported on the NSW stats previously)

However, this should not be case. Statistics should be supported by clear analyses that allow the layperson to understand, particularly, whether their government agencies’ efforts are providing positive results.

Business “warning”

The alert to New South Wales businesses Kirsty refers to is the regular WorkCover News sent out to businesses in hard copy but also available for download.

Below is an excerpt from the article “Safety matters in hard times”

“Many businesses in NSW and across the country are feeling the effect of the global financial crisis. Some employers are cutting costs and workers want to know what that means for them. For the good of your pocket as well as your people, it’s important you uphold safety at work.

Hard times can hit in a number of ways, and nowhere is this more evident than in the workplace. Some businesses might cut their stationery budget; some might put projects or recruitment plans on hold; others might consider a complete restructure. These decisions can affect more than the bottom line.

One thing to consider is the health and safety of your workers. Pressure and change can cause stress and anxiety. If your workers are distracted they may make mistakes or put themselves at risk. If your workers feel insecure, they may not tell you about new hazards. If you take on jobs you don’t have the capacity to deliver, your equipment and people may not cope. Any of these factors could take a human toll.”

As the newsletter is one of the few that Australian OHS regulators publish in hard copy nowadays it is worth registering for. For non-Australian readers, the site is worth bookmarking if overseas.

Occupational violence in fast food restaurants and petrol stations

The Australian media has been abuzz over the last couple of days on several issues concerning violence. Attention increases whenever there is video involved and the latest film of a bashing in Melbourne in a Hungry Jack’s store in the early hours of 13 July 2009 is getting a considerable run.

Most commentators are taking the bashing of 19-year-old Luke Adams as an example of “street violence”. SafetyAtWorkBlog believes that the fact that this event occurred between customers in a workplace, raises questions about the obligations of retail store owners towards health and safety.

The case of Luke Adams again illustrates the reality that surveillance cameras can assist in the apprehension of criminals but does little to reduce the harm to employees and customers. This seems to be contrary to the OHS principles in Australian OHS legislation.

SafetyAtWorkBlog would ask any retailers who choose to operate, particularly, during nighttime

Are the stores designed to reduce (hopefully eliminate) the risk of violent contact between customers and staff?
Are there restrictions on the age or gender of staff who work nightshift?
Is the first aid training provided to staff designed to accommodate the emergency treatment of severely injured customers?
Has the presence of a security guard been tried during nightshifts?
Would the company consider closing a store if the risks to staff and customers became unacceptable?

SafetyAtWorkBlog knows of at least one fast food restaurant in Melbourne that removed its public toilets because of the number of drug overdoses that occurred in the cubicles. This store eventually closed its 24-hour store, partly, because of the unacceptable risk that developed.

The unfortunate linking of fast food restaurants with violent attacks is an issue of all-night trading as much as any other reason. It was just over two weeks ago that a fight in the grounds of a Hungry Jacks restaurant in suburban Melbourne was reported and wrapped into the current topic of supposedly racist-based attacks against Indian students.

The attacks are not limited to Melbourne though. A 19-year-old Korean student, Lee Joon–yub, was killed in Sydney in 2008 after being stabbed at a fast-food restaurant

The risk of occupational violence, as it is more traditionally understood, is increasing according to findings released on 16 July 2009 by the Australian Institute of Criminology. Its report, which also received some media attention from radio, finds that

“The incidence of service station armed robbery has steadily increased over the past decade. ….. This opportunistic targeting of service stations has been attributed to their extended opening hours, their sale of cigarettes and other exchangeable goods, their high volume of cash transactions and their isolation from other businesses. Widespread adoption of crime prevention measures by service stations, such as transfer trays, could help reduce their risk of being robbed…..”

The full report is worth reading closely from an OHS perspective as it identifies the characteristics of services stations (and maybe other all-night retail outlets) that are attractive to the opportunistic robber. We should not dismiss armed robberies as only involving monetary loss to retailers as the study showed that “one-third of armed robbery victims…were individual”.

The AIC report also states that

“…minimal staffing on night shift is seen to increase the risk of armed robbery victimization for service stations.”

This brings in all the OHS advice and research concerning working alone or in isolation. However there must be some sympathy for employers trying to recruit night shift workers for industries where violence is an increasing risk.

The mention of the hazard control measure of transfer trays is gratifying as it fits with a higher order of control measure in OHS parlance by providing an engineering control. However this needs to be backed up by specific training for employees on what to do when required to render assistance outside the enclosed booth.

The application of transfer trays may be valid for fast food stores at nighttime by only offering a drive-thru service and further reducing the risk of customer violence against employees.

Regardless of the physical harm from work tasks arising from working in retail, WorkSafe Victoria advises of four control measures for what it describes as the psychological system of stress, bullying and harassment:

Your workplace culture and management should encourage open and effective communication.

Develop, implement and enforce clear policies and procedures that address bullying, occupational violence, harassment and work pressure in consultation with workers (including young workers) and management.

Where money is handled, put in place security measures to reduce the risk of occupational violence.

Training and procedures should include all staff at risk, including any casual or on hire workers.

What the next generation of graduates wants

A survey of graduates by GradConnection released on 15 July 2009 has important information for Australian companies and provides some optimism for the OHS profession and regulators.

A dominant element of modern employment is work/life balance. In some disciplines this is taken as workplace flexibility. In terms of workplace safety, work/life balance is a euphemism for psychosocial hazards of stress, bullying, fatigue, and workload amongst others. From this position, the survey findings showed that, when asked “What are the most important extra benefits?”, work/life balance scored the most support at almost 39%.

Companies that want to recruit graduates, often those companies which are looking to refresh their staff and workplace culture but also need to build sustainability and longevity, need to review their existing working conditions to match the desires of job seekers. This could be an enormous task for corporations that will take years but smaller companies can afford to be more reactive and flexible and may get the edge on attracting graduates.

It must be acknowledged that over 60% identified high salaries as the most important element in their salary packages. But the work/life balance indicates a growing reality that graduates are less likely to trade off wellbeing for dollars.

This is supported in terms of extra benefits where flexitime and flexible working arrangements gained around 24% and 22% support, respectively. Companies must operate within the time constraints of their industry, suppliers and customers but they should also identify those work processes that allow for flexibility. It may be useful to formalize start and finish times so that there remains a core set of hours within the working day where interaction of staff and clients can be maximised. Some of the social structures are already pushing in this direction with issues of public transport, schooling and childcare already accommodating this flexibility.

David Jenkins, the director of GradConnection, told SafetyAtWorkBlog that

The data we have extracted is drawn from contributions by about 10,500 graduates currently looking at their career options. It gives employers clear indicators as to what grads are looking for in their careers and helps potential employers adjust or increase their messaging about careers on offer at their companies.

Hope for OHS professionals and regulators comes from the fact that of the values that graduates wanted an employer to embrace, health and safety ranked third, behind equal opportunities and environmental sustainability.

This survey is the first generated through the website of GradConnections so the next survey should be able to provide some trend data.

New Australian workplace safety statistics

New South Wales Workcover has released its statistics for 2007/08 on workplace fatalities, injuries and diseases. Statistics are popular posts in SafetyAtWorkBlog and it is recommended that the full report be downloaded.

Statistical incompatibilities continue between Australian States so the NSW statistics should be kept within that State however the report says

A total of 109,835 workplace injuries were reported in 2007/08, a reduction of less than one per cent from 110,160 in 2006/07 and a two per cent reduction in the incidence rate of 37.4 per 1,000 workers in 2006/07 to 36.5 in 2007/08.

Any reduction is good news but over the long term, the government initiatives may be failing. A couple of aims of the National OHS Strategy 2002-2012, to which NSW is committed, are:

to sustain a significant, continual reduction in the incidents of work-related fatalities with a reduction of at least 20 per cent by 30 June 2012 (with a reduction of 10 per cent being achieved by 30 June 2007), and

to reduce the incidence of workplace injury by at least 40 per cent by 30 June 2012 (with a reduction of 20 per cent being achieved by 30 June 2007).

According to WorkCover’s Annual Report for 2002/03 the incidence rate “remained steady in 2001/02 at 20.3”. But the statistical report quoted above says the incidence rate is 36.5 in 2007/08. Clearly the incidence rate has increased by 16.2 over this period.

SafetyAtWorkBlog is, sadly in this case, written principally by an Arts graduate whose grasp of statistics has been illustrated before. But it seems curious that a percentage reduction is being applied to a non-percentage benchmark that is

“the number of injuries per 1,000 employees working in New South Wales”.

There is a lot of room for statistical wriggling in this definition.

SafetyAtWorkBlog is researching more statistical data on the National OHS Strategy to see who is going to meet the target and what will be done by those who do not.

But then again, the world is ending in 2012 which equates to good planning on the government’s part. Non-achievement of OHS targets? Who cares, it’s armageddon anyway.

New research on casino worker risks from secondhand smoke

The yet-to-be-released August 2009 edition of the American Journal of Public Health has an interesting report into the health risks of casino workers in Pennsylvania from second hand tobacco smoke. The research report is quite complex for the casual readerr but the increased level of risk to casino workers seems convincing.

According to the report, secondhand smoke

“in Pennsylvania casinos produces an estimated excess mortality of approximately 6 deaths per year per 10000 workers at risk”.

People in the casinos for 8 hours would be breathing air that would match the “unhealthy air” definition of the US Air Quality Index.

The reseacrh concludes

“It is clear, however, that Pennsylvania casino workers and patrons are put at significant excess risk of heart disease and lung cancer from SHS through a failure to include casinos in the state’s smoke-free-workplace law.”

Randy Dotinga wrote for the Health Behavior News Services on the research report and asked questions of a gambling industry representative:

“Holly Thomsen, a spokesperson for the American Gaming Association, a trade group for the casino industry, said its members are committed to “the highest level of safety and comfort” inside casinos.

Casinos serve both smoking and nonsmoking customers, she said, and “we realize that balancing the needs of these two distinct sets of patrons, as well as those of our employees who don’t smoke, is of paramount importance.”

Sleep disorders and workplace safety – new research grant

Recently, the Australian Government awarded some research grants of which at least one is relevant to workplace safety. $2.5 million was given for the establishment of a Centre for Clinical Research Excellence in Interdisciplinary Sleep Health (CRISH).

When the grant was announced Professor Ron Grunstein of the Woolcock Institute of Medical Research said,

“Adequate sleep is as important as exercise and diet. Sleep loss and sleep disorders contribute to mortality, chronic disease, mental health problems and the economic health burden.

“This funding will allow us to establish a network of leading sleep researchers and physicians in different specialties to investigate the biology of sleep, and look at ways to prevent and treat sleep disorders.”

Amongst several social benefits of the research, the issue of shiftwork health was mentioned. There are many contributory factors to the health of shiftworker and sleep disorders is only one, but an important one.

The most recent Australian data on the costs of sleep disorders was from 2004 by Access Economics, an organisation that the government often relies on for data. Its report, Wake Up Australia, estimates that sleep disorders such as obstructive sleep apnea and insomnia underlie 9.1 per cent of work related injuries.

The origin of this statistic needs to be closely examined in the body of the report (page 23) as there is quite a bit of statistical magic applied however the 9.1% figure has been referred to in relation to the potential benefit of the CRISH project. The statistic is not invalid but it is also not so simple.

Cheeky workers compensation premium statistic

“The premium has dropped eight per cent from last financial year. This is the third consecutive drop in the Commonwealth sector premium rate.” [my emphasis]

Fantastic news – eight per cent reduction in 12 months! The media release goes on:

“… this is a very pleasing result for Commonwealth agencies as it indicates injuries are continuing to fall due to effective prevention strategies that promote safer workplaces.”

The second quote is from Martin Dolan, CEO of Comcare in Australia, on his second-last day in the job.

But 8%? In one year?

The Comcare media release includes a table of premium figures for the five years. The overall premium rate in 2008-09 was 1.36%. For 2009-10 it will be 1.25%, that’s the 8% fall in Comcare media release terms. In reality it is a fall of 0.11%

The premium rate is indeed low and it may be justified in congratulating Comcare on a job well done but expressing such a fall as 8%? This is a cheeky farewell statistic for a CEO which should have said

“a 0.11% fall from 2008-09 and a decline of 0.5% over 4 years”.

This is surely a fairer statistic and a worthy achievement in itself, if not quite so sexy.

UPDATE: 1 July 2009

Martin Dolan is moving to the Australian Transport Safety Bureau.
