Forest not required – indoor air quality and plants

Ever since modern offices have relied on air conditioning for ventilation, indoor air quality has been a contentious occupational issue from other people’s smells to thermal comfort to photocopier toner dust.

The prominence of air quality in offices as an OHS issue can be illustrated by a paragraph from the 1997 edition of Officewise when cigarette smoke remained a real hazard.  No mention was made of plants.

Air in offices may be contaminated by several different
sources, including odours and micro-biological and
chemical contaminants. In an office environment, the
quality of the air is often controlled through an air
conditioning system. A building’s air conditioning
system may be considered as its lungs. The function
of such a system is to draw in outside air, filter, heat,
cool or humidify it and circulate it around the building.
The system expels a portion of the air to the outside
environment and replaces this expelled portion with
fresh or outside air.

Another mining death in Western Australia

Rarely have workplace fatalities gained as much political attention as the current spate of deaths in Western Australia.  Most have related to the iron ore operations of BHP Billiton but, according to one media report, on 8 August 2009

“New Zealander Daniel Williams, 26, died … at the Kanowna Belle mine site near Kalgoorlie, operated by Barrick Gold, after falling from an iron ore path into a hole.”

The media report clearly indicates that there are wider issues in the enforcement of OHS in that State other than just the operations of Barrick Gold.

Not surprisingly the unions are calling for a broader inquiry into safety of the industry.

SafetyAtWorkBlog has heard that Daniel Williams fell over 30 metres while checking a blockage in an ore pass grizzly shortly after midnight.  Perhaps, this should be considered an example of a fall from height moreso than a mining death.

Barrick Gold has been contacted for any additional information

Learning Lessons from the Santika Nightclub Fire

For many years SafetyAtWorkBlog and its forerunner Safety At Work magazine reported on various tragic fires in crowded nightclubs around the world.  Several in recent memory include the 2003 Rhode Island fire that killed 100 patrons and for which, according to an Associated Press report from the time,

Superior Court Judge Francis Darigan Jr sentenced 29-year-old Daniel
Biechele to 15 years, but suspended 11 years of that sentence, and
also ordered three years of probation.

“Superior Court Judge Francis Darigan Jr sentenced 29-year-old Daniel Biechele to 15 years, but suspended 11 years of that sentence, and also ordered three years of probation.”

A brief report on the Rhode Island fire is in the OSHA media archives.

In March 2006, Safety At Work included an AFP report saying

“The municipal council has impeached Buenos Aires Mayor Anibal Ibarra after finding him guilty of dereliction of duty following a December 30, 2004 nightclub fire that killed 194 people.”

An earlier report on the mayor’s response is include at the CrowdSafe website.

Engineering and design company ARUP have provided SafetyAtWorkBlog with an article that analyses recurring elements of nightclub fires using the Santika fire in Bangkok from 1 January 2009 as a most recent incident.  Below is the introduction to the article which can be found in full in the pages listed above.

Our thanks to ARUP for the terrific article.

LEARNING LESSONS FROM THE SANTIKA NIGHTCLUB FIRE

by Dr Marianne Foley and Travis Stirling, Arup Fire, Sydney

In the early hours of New Years Day 2009, fire engulfed Bangkok’s Santika nightclub, killing 64 people and injuring more than 200.  Our knowledge of the events of that night is based on media reports and publicly available information, and the precise cause of the fire is still unclear.  However, we do know that there are strong correlations between this and many similar tragedies at entertainment venues dating back as far as the first half of the twentieth century.  While we wait for the results of the official investigation and coronial enquiries, it’s timely to ask questions about these fires.  Why do they happen over and over again?  Why do so many people lose their lives?  What lessons can be learnt?  And what practical measures can be implemented to stop them happening?

RECURRING MISTAKES

Arup’s analysis of case studies has revealed six themes that commonly contribute to the severity of high-fatality nightclub fires: insufficient exits, the presence of highly flammable materials, a lack of good fire safety systems, confusing environments, pyrotechnics and open flames, and buildings used inappropriately and maintained poorly.  By addressing each of these themes, we aim to provide design solutions that could mitigate the risk of future nightclub disasters.

[The themes in the full article are

  • Insufficient exits
  • Highly flammable materials
  • Fire safety systems
  • Confusing environments
  • Pyrotechnics and open flames
  • Buildings used inappropriately or maintained poorly]

Firefighter trauma

A major element of risk management  is business continuity.  This requires considerable planning, disaster recovery resources, and a long-term focus.

In early 2009 parts of Victoria, some not far from the offices of SafetyAtWorkBlog, were incinerated and across the State over 170 people died. In a conservative western culture like Australia, the bush-fires were the biggest natural disaster in living memory.

The is a Royal Commission into the Victorian Bushfires that is illustrating many of the disaster planning and community continuity needs in risk management.

The Australian Broadcasting Corporation’s “7.30 Report” provided a report on 5 August 2009 which originates from the views of the community and the volunteer firefighters.  One of the issues relevant to safety professionals and risk managers is the psychological impact on volunteer workers.  Many in the report talk of trauma.  Many in the disaster areas have not returned and their are many who remain psychologically harmed.

When a workforce is so closely integrated with a community, rehabilitation is a daunting task and changes a community forever.

Overseas readers may have experienced their own natural disasters such as hurricane Katrina, earthquakes, floods and wildfires.  Many of these stories are reported around the world.  In the recovery phase of any disaster, businesses need to rebuild but are often rebuilding with damaged people.  It would be heartening to see the OHS regulators and OHS professions becoming more involved over the long recovery period.

Heimlich maneuvre has no scientific evidence

The Heimlich manoeuvre is an established first aid technique for removing a blockage, commonly from food.  First aid courses in Australia do not teach the technique as the evidence for the efficacy of the technique is lacking.  The Australian recommendation is to relax the person so that they can cough and to dislodge the blockage through solid thumps on the back.

First aid instructors need to spend time in almost every first aid class to counter the cultural dominance of the Heimlich manoeuvre.

The Australian Broadcasting Corporation’s “The Health Report” investigates the evidence for and against the Heimlich manoeuvre with interviews with Dr Henry Heimlich and with one of Dr Heimlich’s critics, his son Peter.  Peter describes his father as a celebrity doctor.

A Wikipedia article on choking includes the following quote from a 2005 article in the Cincinatti Magazine:

“According to Roger White MD of the Mayo Clinic and American Heart Association (AHA), “There was never any science here. Heimlich overpowered science all along the way with his slick tactics and intimidation, and everyone, including us at the AHA, caved in.”

The relevance of this podcast is very important for OHS professionals as an indication of the competence and validity of first aid training providers.

The podcast also raises other relevant issues concerning evidence-based decision-making, the manipulation and power of the media, and the credibility of subject-matter experts.

The podcast is a fascinating medical tale, a family saga and, perhaps, a case study for media students, but mostly as a precautionary tale for OHS professionals.

Three OHS case studies

The South Australian Industrial Court made three decisions in late July 2009 that are useful cases to look at in order to promote improved health and safety practices but also, in one particular case, to note the approval and endorsement of the judge in the post-incident actions of the employer.

As the SafeWork SA media notice states

“All received 25 per cent discounts from their fines in recognition of their guilty pleas, cooperation, contrition and remedial action to improve their safety systems.”

Case 1

“Bluebird Rail Operations Pty Ltd was fined $30,000 over an incident at its Kilburn workshop in March 2007.  A worker’s arm was crushed beneath a 1,500 kilogram sidewall, which broke loose when a lifting lug failed as it was being lifted to a rail freight wagon under construction.

The court heard that SafeWork SA’s investigation revealed deficiencies in the equipment used, the work processes and the communication channels.

While the worker suffered permanent and debilitating injuries, his employer provided ongoing support including education and training. The employee returned to work after several months and has been promoted within the organisation.”

This case reports a surprisingly short rehabilitation period for a crushed arm.  The words of Magistrate Lieschke should be of considerable note to those OHS professionals who want their clients and companies to go beyond compliance.

“I accept that Bluebird Rail facilitated Mr Sewell’s return to work, in accordance with its legal obligations to provide vocational rehabilitation.  I accept that Bluebird Rail has gone beyond its minimum legal obligations and has provided further re-education support to Mr Sewell, sufficient for him to complete a Diploma in Project Management and for him to now be studying an engineering degree at university. The degree course is being funded by Bluebird Rail.  That is commendable support. Mr Sewell has been promoted and is now working as an assistant project manager.”

Case 2

“International Tastes Pty Ltd was fined $20,250 today after an incident in which an employee had his arm caught in the rotating blades of a pasta-making machine at the company’s Glynde premises in January 2007.

The court was told that the employee was taught to operate the machine with the safety guard open, the interlock switch which would have stopped the machine from operating in such cases was not working, and no safety checks or procedures were in place for either the machine or the tasks involved with its use.

The 24 year old victim suffered fractures, lacerations and nerve damage resulting in a number of operations and considerable pain and suffering.  He has since returned to work interstate with a related company.”

Safety professionals constantly argue for interlocks that cannot be bypassed.  This case shows that the relatively young worker suffered considerably from the incident and has moved interstate to continue with his career.

The judgement raises issues of deep concern to OHS professionals in relation to the level of supervision and induction required for workers and the perennial issue of machine guarding.  The judgement reports the circumstances of the incident:

“On 23 January 2007 [Mr B] suffered serious right arm injuries while operating a pasta making machine in accordance with a method he had recently been taught.  He had received on the job training only and was not given the benefit of any written work procedures.  He had been taught to work in close proximity to unguarded rotating blades.

While using a two litre plastic container to collect pasta mix from the machine the container came into contact with the exposed rotating blades of the adjacent mixing bowl, which in turn dragged his right arm into the blades.”

Case 3

“Central Glass Pty Ltd was fined $9,375 having been prosecuted over an incident in February 2007 at its Salisbury factory, where it makes aluminium window components.

Two workers were manually lifting a slippery steel die weighing 95 kilograms to place it in a press.  In doing so, the die slipped crushing the fingertip of one worker and narrowly missing their feet as it fell to the ground from about waist height.

SafeWork SA told the court there were no safety procedures for the task and the injury could have been averted through the use of mechanical lifting gear, which was later purchased.”

This case can relate to the concept that existed for some time in Australia of a “safe lifting weight”.  This concept has been shown to be a myth as it focuses on only one part of the work process and assumes that the particular lift is outside the other lifting actions that a worker may have been performing previously. It also assumes that everyone has a similar lifting capacity.

The judgement of this case provides more detail

“On 16 February 2007 Central Glass Pty Ltd unnecessarily exposed its employee [Mr R] to a risk of serious injury at work.

With the help of another worker [Mr R]was required to manually lift an oily 95kg steel die from ground level and place it in a close fitting slot in a press at about waist height.  While doing so the die slipped and crushed one of [Mr R’s]fingers.  The die then fell to the ground narrowly missing the feet of [Mr R]and of his colleague. [Mr R] suffered a crush injury to the tip of his left middle finger.

Central Glass had not previously carried out any hazard identification and risk assessment process in relation to changing and fitting dies.  It did not have any safe work procedure for this task and did not provide adequate safety control measures such as mechanical lifting assistance.”

New old US research into driving and talking

The New York Times has revealed research on the hazards of driving and using mobile phones that was withheld since 2003.   The newspaper understandably focuses on the intrigue that prevented the report from being released but the content of the report has the potential to substantially change how companies “manage” the hazard of their staff using mobile phones whilst driving. Pages from original

The report, obtained through Freedom of Information and made available on the newspaper’s website, was a  substantial project for the National Highway Traffic Safety Administration and, according to NYTimes:

“The research mirrors other studies about the dangers of multitasking behind the wheel. Research shows that motorists talking on a phone are four times as likely to crash as other drivers, and are as likely to cause an accident as someone with a .08 blood alcohol content.”

The full report is available by clicking on the image in this post.
