Gas leaks at Esso’s Longford plant

WorkSafe Victoria is investigating two gas leaks that occurred on 6 November 2009 at the Longford gas plant owned by Esso. This plant was subject to a fatal explosion in 1998 and was recently written about on SafetyAtWorkBlog.

According to an ABC news report on 11 November 2009, repairing one leak led to a consequent leak and a “plant operator suffered minor injuries when he fell during the incident.”

A WorkSafe Victoria spokesperson told SafetyAtWorkBlog that inspectors have been on site for several days, the area of the incident is still not operational and that any restitution work in the area will need WorkSafe’s approval.

Asbestos is an example of immoral economic growth

The financial newspapers often refere to a BRIC group of countries or, rather, economies. This stands for Brazil, Russia, India and China and is used to describe the forecasted economic powerhouses for this century. But there is also the risk of economic growth without morality. India is a case in point and asbestos can be an example.

The health hazards of asbestos have been established for decades but only officially acknowledged more recently. One would expect that when some countries ban the import, export and manufacture of a product that other countries may suspect that something may be amiss.

In the introduction to the September 2008 book “India’s Asbestos Time Bomb” Laurie Kazan-Allen writes

“Historically the burden of industrial pollution has reached the developing world much faster than the fruits of industrial growth” writes Dr. Sanjay Chaturvedi. This statement is well illustrated by the evolution of the asbestos industry in India. In the frantic rush for economic development, there has been a pervasive lack of concern for the health of workers and the contamination of the environment. Sacrificing the lives of the few for the “good” of the many, the Indian Government has knowingly colluded in this sad state of affairs.”

Kazan-Allen is a longtime campaigner on asbestos. In 2001 she put this question to the Canadian Medical Association Journal.

“Chrysotile has caused and is continuing to cause disease and death worldwide. It is hypocritical for Canada to continue to produce chrysotile when it is not prepared to use it domestically. If chrysotile is unsuitable for Canadian lungs, how does it become suitable for Korean, Indian and Japanese lungs?”

A foundation of public health and workplace safety management is that bad practices, immoral practices, are corrected, not accommodated. At some point the exploitation of others for the financial betterment of a few must end. Could that lead to a “compassionate capitalism” or is that just another term for “socialism”? These semantics are being argued at the moment in the United States over health care but the question needs to be asked globally, just as it is on climate change and on the financial markets.

The global implications of poor OHS management and practices needs to be placed on the policy agenda not only of the ILO, United Nations and trade union movement, but the business groups, and professional associations who need to develop their social charters. If those voices are not added to the debate, safety will also be a fringe issue and it is too important for that.

EHS workshop report and Australian nanoparticles reports

In October 2009 a workshop was held on worker safety by the Worker Education and Training Program (WETP), a part of the US National Institute of Environmental Health Sciences. Many of the topics raised in the workshop – REACH, Globally Harmonized System (GHS) of Classification and Labeling of Chemicals, and nanotechnology would be issues or hazards familiar to most SafetyAtWorkBlog readers.

This report on the workshop, released in November 2009, is highlighted here because it is a very good example of a basic report on a workshop that makes the reader regret that they couldn’t be there. This respond encourages readers to make the extra effort for the next set of workshops – a major benefit of such reports and, sometimes, the main reason.

The mention 0f nanotechnology is a good link to two new reports on the issue released by Safe Work Australia on 4 November 2009.

Engineered nanomaterials: Evidence on the effectiveness of workplace controls “explores the effectiveness of workplace controls to prevent exposure to engineered nanomaterials.” According to a media release on the reports this report found:

“current control and risk management methods can protect workers from exposure to engineered nanomaterials

enclosure of processes involving nanomaterials and correctly designed and installed extraction ventilation can both significantly reduce worker exposure to nanomaterials, and

a precautionary approach is recommended for handling nanomaterials in the workplace.”

The lack of available health effects data has directly led to the precautionary position in recommendations but it is good to see that the hierarchy of controls (old technology) is being applied to new technology. The report gets to a point of recommending a combination of

“…controls [that] should provide a robust regime through which nanomaterials exposure to workers will be reduced to very low levels.”

The bibliography in this report is also excellent and includes a comparative table of the research reports and papers analysed.

Engineered nanomaterials: A review of toxicology and health hazards was a literature review that reports:

“there is no conclusive evidence to suggest that engineered nanomaterials have a unique toxicity. However, sufficient toxicity tests have not yet been conducted for most engineered nanomaterials

nanoparticles tend to be more bio-reactive, and hence potentially more toxic, than larger particles of the same material, and

carbon nanotubes are potentially hazardous to health if inhaled in sufficient quantity.”

Nanotechnology is a difficult area of OHS study as there is so much research material coming through that it is (probably more than) a full-time job just to stay current. The literature review into toxicology makes a point that it is important to remember in this field.

“A wide variety of in vitro and in vivo experimental protocols have been used to assess biological responses to NPs, some of these yield more useful data for occupational risk assessment than others. Some are potentially misleading.” [emphasis added]

The second of these reports was a good introduction to the general issues of health risks but must be stressed that these reports deal with engineered nanoparticle(s) (ENPs) which are defined as

“A nanoparticle with at least one dimensions between approximately 1 nm and 100 nm and manufactured to have specific properties or composition. “

Increasing research into any issue almost always leads to a fragmentation of the discipline into subsets. That research into engineered nanoparticles is different from regular nanoparticles needs to be remembered. As the report itself says

“…the major thrust of the research is in relation to identifying potential hazards for assessment of occupational safety since working with ENPs is likely to be where most exposure occurs. In contrast to ambient particulate air pollution, where health effects have been observed and research has been aimed at discovering the causative agents and mechanisms, the reverse is true for ENPs.”

Tom Phillips AM, chair of the Safe Work Australia Council said , in a media statement,

“Safe Work Australia has requested that the National Industrial Chemicals Notification and Assessment Scheme undertake a formal assessment of carbon nanotubes for hazard classification to clarify regulation of these nanomaterials.

“We have also requested that CSIRO develop guidance for the safe handling and disposal of carbon nanotubes, which will be a useful resource for OHS managers.”

It is good to see Safe Work Australia (now an independent statutory body) take one of the ACTU recommendations from its 2009 factsheet.

Good corporate advice tainted by poisonous product

In Matt Peacock’s book, “Killer Company“, an entire chapter is devoted to the legacy of the James Hardie chairman, John B Reid. In Peacock’s talk at Trades Hall in October 2009, he mentioned that Reid had once published a book called “Commonsense Corporate Governance”. The apparent hypocrisy of an executive of a company that knowingly sells toxic material while advising others on how to manage their corporation responsibly generated chuckles of disbelief in the Trade Hall audience.

Reid book cover 001 SafetyAtWorkBlog obtained a copy of John Reid’s book to see first-hand that someone could do such a thing. A sad part of all this is that the advice in the book is sensible but Reid’s “legacy” now taints all he does and all he says.

One random example of the advice he provides concerns dealing with consultants:

“Where, as with solicitors and auditors, it is imperative for the company to retain them, company staff need to be reminded that the professional advisers are paid for on the basis of the time that they spend on the company’s business. This is not predetermined by the nature of the task. In large measure it is affected by the decisions made and by the homework done within the company. What does this mean?

First, the imposition of new and more demanding, and frequently less precise, legislation on all manner of subjects has made management and, as a result, directors, nervous about things that directors 50 years ago would have dealt with very quickly-and inexpensively. Further, the increasing number of specialists necessary within a company’s own payroll is a result of this legislative epidemic, and has produced a reinforcement of this culture of caution and, occasionally, of fear.”

Safety professionals may want to take particular note of this corporate imperative.

Peacock points to the strict confidentiality clauses that Hardie included in any settlements in the 1970s. Peacock writes (p 156)

“Secrecy indeed was Hardie’s byword, one endorsed by the chairman, who would later advise aspiring directors to ‘remain silent where there is criticism’.”

Reid recommended this in a bulleted list of ways to handle the media.

John B Reid, whose personal wealth was estimated at $A181 million in 2004, is not unique in advising companies while also having a tarnished corporate reputation. Some argue that the adjective “good businessman” is a tautology.

There is no doubt that Reid was an active philanthropist and corporate citizen. He was awarded an Order of Australia for “service to industry” – no citation is available to explain the decision. In 2006, he received the Goldman Sachs JBWere Philanthropy Leadership Award.

Greek tragedies were full of hubris and examples of the single flaw that made good men do bad things. If the plays of Euripides, Aeschylus and Sophocles have yet to be analysed for their advice to corporate executives, they should be, for not only do they show human flaws but human corporate flaws.

John B Reid’s book on corporate governance is an easy read and has valuable lessons but it is now a book that makes the reader feel dirty.

Evidence of heart attacks due to secondhand smoke

According to a media release from the Institute of Medicine (IOM) in the United States, a new research report says:

“Smoking bans are effective at reducing the risk of heart attacks and heart disease associated with exposure to secondhand smoke, says a new report from the Institute of Medicine. The report also confirms there is sufficient evidence that breathing secondhand smoke boosts nonsmokers’ risk for heart problems, adding that indirect evidence indicating that even relatively brief exposures could lead to a heart attack is compelling.”

The report claims to have undertaken “a comprehensive review of published and unpublished data and testimony on the relationship between secondhand smoke and short-term and long-term heart problems”. It has looked at “animal research and epidemiological studies” and “data on particulate matter in smoke from other pollution source”.

The study was sponsored by the U.S. Centers for Disease Control and Prevention which has summarised the report on a new webpage. SafetyAtWorkBlog has been unable to obtain a copy of the full report.

The report is unlikely to help those safety professionals who need to control the hazard of secondhand smoke in the workplace. Legislation has been in some States of America for over thirty years identifying where people cannot smoke and around the world the major control measures are moving smokers outside and encouraging them to quit.

The IOM report seems to confirm the seriousness of the issue but provides no new ideas for control. This would be like producing a new research report that says mercury, lead or asbestos are harmful – like duh?

US OSHA provides some data on legislative interventions on tobacco smoke but new information on this hazard in the workplace setting is thin. The US Cancer Institute issued a monograph in 1999 defining ETS as

“…an important source of exposure to toxic air contaminants indoors. There is also some exposure outdoors in the vicinity of smokers. Despite an increasing number of restrictions on smoking and increased awareness of health impacts, exposures in the home, especially of infants and children, continue to be a public health concern. ETS exposure is causally associated with a number of health effects.”

More recent monographs are available at the Tobacco Control Research site.

The UK Health & Safety Executive provides this specific environmental tobacco smoke advice

Employers should have a specific policy on smoking in the workplace.
Employers should take action to reduce the risk to the health and safety of their employees from second hand smoke to as low a level as is reasonably practicable.
Smoking policy should give priority to the needs of non-smokers who do not wish to breathe tobacco smoke.
Employers should consult their employees and their representatives on the appropriate smoking policy to suit their particular workplace.

The status of workplace smoking and secondhand smoke in most westernised countries seems to have plateau-ed or perhaps got to the point where every control measure that is reasonably practicable has been done.

That people continue to die directly and indirectly from tobacco smoke illustrates the flaw in the reasonably practicable approach to safety legislation and management which is “so what do we do next?” Perhaps the attention being given to nano particles may help but is it the particulates in secondhand smoke that is the problem or the fumes themselves? Regardless, a new approach is needed to control this persistent workplace hazard. Shoving smokers onto the streets and balconies is not enough.

GHS is coming to the United States

On 30 September 2009 the Occupational Safety and Health Administration in the United States said in a media statement:

A proposed rule to align the Occupational Safety and Health Administration’s Hazard Communication Standard (HCS) with provisions of the United Nations Globally Harmonized System of Classification and Labelling of Chemicals (GHS) will be published in the September 30 Federal Register.

Jordan Barab, acting Assistant Secretary of Labor for OSHA said

“The proposal to align the hazard communication standard with the GHS will improve the consistency and effectiveness of hazard communications and reduce chemical-related injuries, illnesses and fatalities…… Following the GHS approach will increase workplace safety, facilitate international trade in chemicals, and generate cost savings from production efficiencies for firms that manufacture and use hazardous chemicals.”

On 6 October 2009, Safe Work Australia released the draft “Australian Criteria for the Classification Hazardous Chemicals”.

The closing date for comments is 18 December 2009.

Safe Work Australia stresses what the draft is not and the web page on the issue is very important to read.

Safe Work Australia says it

“…will be preparing guidance material for different audiences on the GHS and introducing two training courses (as basic and an expert one) to understand GHS classification.”

It should also be noted that the draft Classification Criteria is being revised in the context of the OHS harmonisation program of the Federal Government.

Increasing risk of silicosis in the majority world

Australian safety expert and activist Melody Kemp reported from the annual meeting of the Asian Network for the Rights of Occupational Accident Victims (ANROAV) that was held in late September 2009 in Phnom Penh.

The meeting featured many stories about the increasing risk of silicosis in Asia. Melody writes in the 27 September edition of the blog “In These Times”:

“Silicosis afflicts workers working with gems, ceramics, rock blasting, drilling and crushing, and mining. It haunts unprotected workers in glassworks, mines and foundries, as well as those who live within reach of the dust. It’s usually fatal by the time it is diagnosed.

Largely eradicated in the economic North, silicosis is now the scourge of the Global South. Millions die from the illness each year.”

The size of the growing occupational and community threat is frightening.

“China alone reports over 100,000 new cases of industrial lung disease per year, and has more than 4 million existing cases. And those are just the official figures. Even industrially advanced South Korea sees over 1,000 new cases of occupational chest disease each year, reported Dr. Domyung Paek, a pulmonary specialist from Seoul National University.”

Melody has contacted SafetyAtWorkBlog asking for assistance in attracting occupational medical experts to Cambodia and other countries undergoing rapid industrialisation. She can be contacted by clicking HERE.
