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.

Depression and workplace stress rehabilitation

In January 2009, SafetyAtWorkBlog reported on the end of a political saga involving parliamentarian Paula Wriedt.  Ms Wriedt has since become a spokesperson for the treatment of depression and on 10 August she spoke with the Australian Broadcasting Corporation about more resources for the treatment of mental health issues in the young.

Do health professionals make the best OHS leaders?

David Michaels has been nominated by President Obama as the new Assistant Secretary for the Occupational Safety and Health Administration in the Department of Labor.  (A brief profile of Michaels is available HERE.)  A posting at a US Workers’ Compensation website links through to a discussion on the potential impacts of the Michaels’ appointment.

There are several telling quotes in the podcast.  Sidney Shapiro, a law professor at Wake Forest University, says that OHS achieves more when run by someone with a health professional background.

“…I think it’s important that we know that David Michaels is a health professional.  And I think OSHA’s done best when it’s had administrators from the public health community.  It is, after all, a public health agency.  More times than many of us would wish, it’s been headed by someone who’s been an adamant critic of OSHA and has come from industry or been an industry lawyer.”

Whether this position can be applied to regulators in other jurisdictions is an interesting question.

The Chair of the UK HSE Board, Judith Hackett,  has a background in petrochemicals.  The CEO of the HSE, Geoffrey Podger, has a background in the civil service, health and food safety.   The chair of the Safe Work Australia Council, Tom Phillips was the former CEO of car manufacturer, Mitsubishi, and has served on a range of industrial company boards in South Australia.  The Chair of WorkSafe BC board, Roslyn Kunin, harks from human resources and the labour market.   Greg Tweedly CEO of WorkSafe Victoria has a background in insurance and compensation.  Nina Lyhne of WorkSafe WA comes from road safety and compensation.

This unrepresentative sample shows a mix of experience and not all from health promotion.  If the list was comprehensive, it would be interesting to see if Shapiro’s comments stack up and to see how many trade union officials have moved to “the top” or will simply remain “on the board”.

The Living on Earth podcast includes the following quote from Michaels from some time ago:

“What polluters have seen is that the strategy that the tobacco industry came up with, which essentially is questioning the science, find the controversy and magnify that controversy, is very successful in slowing down public health protections.  And so the scientists who used to work for the tobacco industry are now working for most major chemical companies.  They don’t have to show a chemical exposure is safe.  All they have to do is show that the other studies are in question somehow.  And by raising that level of uncertainty, they throw essentially a monkey wrench into the system.”

This statement could generate optimism for OSHA’s future but there are many examples of the views of environmentalists changing once they move into the corporate world.  Politicians like Australia’s Minister for the Environment, Peter Garrett, is an obvious recent Australian example.  Harry Butler in the 1970s was roundly criticised for “selling out” to the petrochemical industry.

However, the appointment of David Michaels pans out, it will be an interesting one to watch, particularly if the US Democrats can stay in power for more than Obama’s two terms.

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.

Does a new mobile telephone equal productivity increases?

The largest Australian telecommunications company, Telstra, announced the release today of  a new service for mobile telephones aimed at the business sector.  Below are some excerpts from the media release:

Telstra-HTC-Snap-Front-hires“Telstra launches new smartphone to power workforce productivity

August 3, 2009 – Business professionals have a powerful new productivity tool at their disposal with the launch of the new HTC Snap on the Telstra Next G™ network.

Available from 11 August, the Snap is a Windows Mobile®-powered smartphone that helps users get the most out of every hour by connecting them with email, their office calendar and the mobile internet in real-time….

Telstra Business Executive Director, Cathy Aston, said the HTC snap was the ideal productivity device for busy business people who need to respond to clients and manage their email on the go.”

The email-ready HTC Snap lets users steal back otherwise lost work time by keeping them
connected to email on the commute to work, on the way to the airport or when waiting to attend a
meeting.

“The email-ready HTC Snap lets users steal back otherwise lost work time by keeping them connected to email on the commute to work, on the way to the airport or when waiting to attend a meeting.”

“Telstra Product Management Executive Director, Ross Fielding, said this remarkably slim smartphone set a new benchmark for productivity device affordability and would appeal to business people who demand always-on email, as well as consumers who are increasingly interested in messaging capabilities on the go.”

The words emphasised above indicate a dominant thought that business people are obliged to be contactable at all times of the week.  Research is beginning to show that this is becoming an unsafe practice, if it is not already (see below).  The “steal back otherwise lost work time” is of concern.  What time is being referred to going to the toilet, spending time with one’s family, countering fatigue and stress through sleep?

In December 2008, Telstra undertook a survey of small business operators.  The survey showed that many would be working over the Christmas break.  Telstra Business Group Managing Director, Deena Shiff said

“In 2008, Australian SMEs have been world leaders in the take up of mobile technology based on the Telstra Next G™ network – in fact businesses are now using mobile technology more than fixed line phones and data….

The key is to use technology not to intrude on personal time, but to manage the ongoing needs of the business in a more efficient way that doesn’t keep people away from family.” [my emphasis]

In 2006, the Chartered Institute for Personnel and Developmetn (CIPD) undertook research that said

“The phenomenon of “teleworking” has been overexaggerated, is unlikely ever to be a prospect for the majority of workers, and may be overshadowing far more effective means of improving work-life balance…”

The most important feature of modern mobile phones is the OFF button.
