Eliminate the hazards

The first control measure on the “hierarchy of controls” is to eliminate the hazard. OHS consultants and professionals should always consider ways to achieve this. It may prove to be impractical, or politically unpopular, but it should always be discussed or recommended. Reports and submissions that do not consider this control measure can be considered invalid.

In late-January 2009, the organic farmers in Australia reminded the media that its farming members are developing a safer industry for the customer and the producer. This industry has boomed in Australia since the 1970’s in as a result of a desire and commitment to “eliminate the hazard”.

Interviews conducted by Biological Farmers of Australia (BFA) to help discover why producers ‘go organic’ reveal a high number of farmers consider the switch for the health of themselves and their families.

Rob Bauer (Bauers Organic Farm, Qld), one of Australia’s largest organic horticultural growers, says he turned to organic farming 27 ago after farmers in his area became ill with cancer.

He says he wanted to decrease health risks associated with synthetic farm chemicals.

“I started thinking about farming differently after growing up in the Lockyer Valley (Qld) where friends and family passed away in their fifties after years of intensive agrichemical production.”

He says neurological problems, tumours, and cancer were among the chronic diseases he watched take their toll on his local farming community.

“I wasn’t comfortable with producing food using harsh farm chemicals for consumers,” he says.

Steve Skopilianos, commercial lettuce producer from Ladybird Organics in Keilor (Vic) looked into organics when he started a family.

“We had been applying pesticide blends with no understanding of their effect on people and employees. There were times prior to organic conversion where I would not take my own produce home for my family to eat.”

Biodynamic producers of macadamias are happy to avoid high levels of agrichemicals typically used on the nuts.

“Working without a high exposure to synthetic chemical farm products is a weight off your mind,” says Marco Bobbert, from Wodonga Park Fruit and Nuts macadamia plantation (Qld), certified biodynamic since 1987.

He says direct chemical exposure could easily occur on conventional farms from accidents in production. “All it takes is a broken spray pipe.”

He says it is not just organic farmers who are concerned – “All farmers try to minimise their contact with chemicals on-farm. But organic production actively works toward negating that risk”.

Research has shown there is good reason for producers’ concern – a high exposure to some farm chemicals can lead to major health problems.

Particularly problematic substances include organophosphate insecticides and pesticides, which have been connected to several types of cancer, sterility and cognitive deficits (1).

The agrichemical endosulfan is one example of a highly toxic organochlorine cyclodiene) insecticide still in use in Australia.

New research on behavioral safety

The New York Times (and other newspapers) reported on an article in the latest edition of the NSC Journal of Safety Research. It is worth considering when the behavioural-based safety advocates come a-knocking.

According the media reports the article reports on “knowledge gaps” in research into behavioural safety. It summarises the discipline, or alchemy depending on your experience with the advocates, very well.

“Behavioral safety” is becoming more popular as safety practitioners seek to better understand and develop strategies to prevent workplace injuries. Behavioral safety is the science of observing workers’ behaviors to determine where a different behavior or set of behaviors may have prevented or lessened the severity of injury. The study defines behavioral safety as an approach to improve safety performance through peer observations, goal setting, feedback, and celebrations or incentives for reaching safety goals.”

Thankfully it sensibly recommends that behavioural safety be applied as part of a broader safety management system. In fact broader than many others suggest. The study says that “psychological, social, engineering and organizational factors” should be considered and it acknowledges that how these factors affect behavioural safety is still poorly understood. It suggests these areas for further research attention:

“Impact of behavioral safety interventions on rates of injury, illness and fatalities.
Appropriateness of the basic elements of behavioral safety across different industry sectors.
Relationship between behavioral safety and a greater safety culture.
Role of performance feedback in creating behavioral change.
Effectiveness of tangible and non tangible rewards on behavioral change.”

Some of these factors would best apply through research by the OHS regulators – a rare commodity – but they indicate some of the areas which OHS professionals should consider more carefully.

Clearly behavioural safety is still a developing area of study and application. It reinforces the position that behavioural safety is still not a panacea, regardless of the claims of spruikers. Behavioural safety is one of the tools available to OHS professional and perhaps one that should not distract us from more effective and practical safety initiatives.

Possible cancer cluster at fish hatchery

For several weeks News Limited papers have reporting weird goings on around a fish hatchery in Queensland. In a small area of Cooloothin Creek people living on properties neighbouring the Sunland Fish Hatchery have been noticing an increase in cancers. The latest victim is a hatchery foreman who has been diagnosed with bowel cancer.

The issue has been bubbling along since a two-headed fish larva was discovered around 11 January 2009. On 26 January 2009, the foreman has formally requested an investigation into a cancer cluster. The 26 January quotes cancer expert, Bruce Armstrong.

Professor Armstrong said the fact there was more than one type of cancer would normally militate against a cluster. But the deaths and health problems among chickens, horses and dogs — as well as the fish — were extremely worrisome. “Clearly, there does seem to be an ecological issue here,” he said.

He suggested an investigation could help determine if the agrichemicals posed a threat to humans.

Local residents produced a video about the issue of crop spraying which is available on YouTube.

This current case will increase the pressure on government’s for increased regulation of farm chemicals and delivery systems.

UPDATE – 28 January 2009

Queensland’s Primary Industries and Fisheries Minister Tim Mulherin has established a taskforce to investigate the Noosa fish abnormalities. It’s first meeting will be on 28 January 2009.

It includes private aquaculture veterinarian Dr Matt Landos, who says the available evidence points to farm chemicals.

According to a ministerial media release Dr Landos said

“I am extremely pleased that the minister is keen to progress this issue and welcome the opportunity to work with the minister and the State Government. We need to consider interim alternative chemicals and farming practices in co-operation with macadamia farmers, to provide improved safety for aquatic animals and sustainable macadamia production.”

The ministerial release also said that

“claims of a cancer cluster in the area are a matter for Queensland Health to consider.

Queensland Health has said the need for an investigation into an alleged cancer cluster will be determined once specific information is received from the community about their health concerns.”

SafetyAtWorkBlog will be following the taskforce’s progress.

New potential carcinogen and occupational asthma

There are two reports of concern in the next edition of the journal of Occupational and Environmental Medicine. One (Cancer risks in chemical production workers exposed to 2-mercaptobenzothiazole – Online First Occup Environ Med 2009; 10.1136/oem.2008.041400) raises the increasing likelihood that 2-mercaptobenzothiazole, or MBT, could be carcinogenic.

The article reports on a study of workers in a rubber chemicals plant in North Wales. It found that

“Based on national statistics for expected death rates, workers exposed to MBT were twice as likely to die of gut (large intestine) and bladder cancers.

Based on national statistics for expected new cases of cancer, they were also twice as likely to be diagnosed with bladder cancer, and four times as likely to be diagnosed with multiple myeloma (bone marrow cancer).”

The other article (Occupational exposures to asthma among nursing professionals Online First Occup Environ Med 2009; 10.1136/oem.2008.042382) is similarly worrying. Moreso because the chemical products mentioned in the report are well-known substances, such as latex gloves and gluteraldehyde, and control measures are very well established.

“…those who regularly cleaned instruments were 67% more likely to report a diagnosis of asthma since starting their job.

And nurses who were regularly exposed to general cleaning products and disinfectants were 72% more likely to say they had been newly diagnosed with asthma, and 57% more likely to report symptoms similar to asthma.

Those nurses working with solvents and glues used in patient care were also 51% more likely to say they had symptoms similar to asthma.”

In both these circumstances occupational health and safety has established control measures that can reduce the harm from these products. What they illustrate is that OHS professionals may apply a consistent standard of expectations that often strengthen as clients remain in one specific industrial demographic but workplaces, decades after hazards are known, have a highly variable level of safety and compliance. This sounds obvious but specialisation can lead to complacency in advisers as much as customers.

It is also useful to note that the carcinogen research was in North Wales and the asthma study in Texas. Both these countries have strong OHS legislation and a good amount of OHS resources but still unacceptable levels of occupational illness. It is this level of resource and attention that has provided the chance for these studies to be undertaken.

A sort-of resolution for Paula Wriedt

Paula Wriedt, a Tasmanian Member of Parliament who attempted suicide in August 2008, resigned on 18 January 2009. According to her media statement

“I have made a significant recovery since my hospitalisation in August, but I believe it is in my best interests, and the interests of my family, to concentrate on improving my health away from the daily pressures of being a member of Parliament.

“This illness has had a significant impact on my life.

“The many demands I faced last year, on both a professional and personal level, meant I neglected to take stock of my health until it was too late.

“During this time, I made a mistake by forming an inappropriate relationship with a member of my staff. This had significant implications for the families involved, and I am not proud of my actions.

“I deeply regret the hurt that has been caused by this.”

She goes on to speak positively of undertaking meaningful work outside of politics. It is hoped that Paula does not feel obliged to follow other politicians into promoting depression support services. For most Australians Paula Wriedt will be associated with her affair and suicide attempt. Tasmanians should remember her as a good parliamentarian, as mentioned by the current Premier David Bartlett (who is only slightly older than Paula at 41), and for her achievements in the education portfolio.

Absence management survey results

On January 8 2009, the Mercer’s 2008 Pan-European Health & Benefit Report was released. It had some useful information about the causes of workplace absenteeism in Europe. The information was compiled in 2008 so is as current as can be but also occurred in a period of severe economic unrest.

As with all studies, the applicability to other nations and regions is up for debate but the data is a great starting point for discussion on managing these issues in workplaces.

According to the available report information

“Musculoskeletal conditions were identified by 78 percent of respondents as the cause of most long-term absences. Thirty-one percent specifically referenced lower back pain and 47 percent other musculoskeletal conditions. Stress and mental health issues (52 percent) and cancer conditions (20 percent) were also featured amongst the highest disability causes.”

By looking at policies and practices in the multi-jurisdictional structure of Europe, the demographic variations and management initiatives may be applicable elsewhere.

As Steve Clements of Mercer says

“Absence management remains haphazard at best. Targeted absence management policies and procedures are by no means universally applied, and even the ability to quickly and accurately measure absence remains fairly poor. Many employers offer a broad range of health-related benefits, but their presence is driven by recruitment and retention, and it appears there is only sporadic evidence of integration of these benefits within a broader employee health and wellness or absence management agenda. At a time when cost is under the microscope, employee absence remains under-managed and presents a great opportunity for savings and improved productivity.”

Workplace health – international response

Rory O’Neil, editor of Hazards magazine has written in response the SafetyAtWorkBlog posting on workhealth initiatives. His response was posted on one of the many safety-related Internet discussion forums and was brought to my attention by Andrew Cutz and others.

WorkHealth initiatives – it’s about the workers, isn’t it?

The Victorian system is not garnering the necessary support because it is lifestyle focussed and has not answered concerns raised by unions, who want the programme to also address conditions caused or exacerbated by work. Business is annoyed because unions had the audacity to require that workers have a say in measures relating to their health (the poor little things are supposed to be passive recipients, apparently, taking the medicine and behaving like good little children). Below is my little news summary from 1 November.

There’s a rash of these lifestyle related interventions around the industrialised world. The EU is pushing fruit into some workers’ mouths, for example, as part of the ISAFRUIT project. However, two apples a day don’t make a worker as happy and healthy as a pay rise or some constructive participation in decisions about how work is organised, how satisfying that work might be and at what pace and for what reward. Or wage levels that allow healthy dietary choices for the whole family, at home and at work.

The lifestyle-focussed projects tend to be couched in language about making the worker healthier but are frequently more concerned with reducing sickness absence costs and winnowing out all but the superdrones that can work long hours in bad jobs without complaint. If employers cared so much, sickness absence procedures would not include punitive elements and health and safety whistleblowers wouldn’t be an endangered species. The unionisation campaign at Smithfield is a pretty clear case in point – bad jobs, bad pay, runaway strains and injuries and victimisation for those would stood up against it.

I’ve nothing against been given free fruit, free gym membership or anything free for that. But the time to use the gym, eat the fruit and have a life both inside and outside work that is meaningful and fulfilling might make it easier to swallow. This issue is about good jobs, with good conditions of employment and good remuneration. If workplace health policy ignores these factors, then it is an irresponsible diversion.

This is my latest measured contribution on the issue:

You big fat liars [Hazards 104, October-December 2008]
Oh, they say it’s because they care. They’ll weigh us, keep tabs on our bad habits and ask questions when we are sick. And when we fall short of perfection, they label us shirkers, sickos and slobs. Hazards editor Rory O’Neill questions whether all this attention from employers is really for our own good. more
More on this theme: www.hazards.org/workandhealth

If ACOEM is developing policy, then it should consider how work factors dominate our working days and frames the comfort and health of our working lives and beyond. That means integrating better work into any health model and making sure workers are allowed to participate fully in – and influence the design and operation of – any workplace health system.

Rory also points to the Trade Unions Congress posting that quotes the Victorian union response to the WorkHealth program and says this about the major employer group’s position:

The employers’ group, meanwhile, is adamant it will not accept the changes under any circumstances. David Gregory, the head of workplace relations at the Victorian Employers Chamber of Commerce and Industry, said it amounted to making the programme an ‘industrial weapon.’
