Summer heat, fatigue and UV – a speculative solution

Let’s pull together several workplace hazards and suggest one control measure that may address all of them at once.  Of course, the control may generate other work hazards or management challenges.

In Summer, work occurs throughout daylight hours.  The long days, and possibly daylight savings, maximise the window of productivity for workers, particularly those who work outside – building construction, housing, rail maintenance, roadworks…..  Such work can lead to the workplace hazards of excessive exposure to ultraviolet radiation (UV), fatigue, and heat stress.

Each of these hazards has its own separate advocates for safe practices, as well as the OHS regulator that provides guidance on all hazards.  This complicates the management of OHS because sometimes there are conflicting control measures or at least measures that are incompatible with the needs and desires of the workforce.  If we think of this combination of hazards as a Gordian Knot, we could solve the problem by splitting the working day into two sessions on either side of a sleep break or, as the November 2009 edition of the Harvard Health Letter calls it, a nap.

The Harvard article, “Napping may not be such a no-no”, discusses the good and bad of napping and the tone of the article seems to look at this control measure mainly for office-based or administrative tasks.

“[Robert Stickgold, a Harvard sleep researcher] says his and others’ findings argue for employer policies that actively encourage napping, especially in today’s knowledge-based economy.  Some companies have set up nap rooms, and Google has “nap pods” that block out light and sound.”

The article suggest a couple of suggestions

“Keep it short. A 20- to 30-minute nap may be ideal. Even just napping for a few minutes has benefits. Longer naps can lead to grogginess.

Find a dark, quiet, cool place. Reducing light and noise helps most people get to sleep faster. Cool temperatures are helpful, too.

Plan on it. Waiting till sleepiness gets so bad that you have to take a nap can be dangerous if you’re driving. A regular nap time may also help you get to sleep faster and wake up quicker.

Don’t feel guilty! A nap can make you more productive at work and at home.”

But sometimes SafetyAtWorkBlog likes to extend a solution to the bigger picture.

In Australia, the peak period for extreme levels of UV is between the daylight savings hours of 10.00am and 1.00pm, or 3.00pm in some instances.  If an outside work site suspended work for three hours, the employees could have lunch and rest, or sleep, in the shade.  Depending on the location of the work site, some could even go home for that period.

The work day could still be as productive by starting early and finishing late, basically inserting a rest break of several hours into the middle of the daytime shift.  There is evidence in the Harvard article that productivity could be increased as a result of the rest break.

On quick reflection, this scenario is a fantasy because the ramifications of such a change are huge, and OHS is unlikely to achieve any structural cultural change of this magnitude, but it remains an attractive fantasy.  The attraction is the logical simplicity but, of course, logic is often bashed around by reality and below are some of those realities:

  • Expanded work hours for a construction adjacent to a residential area working on the 9 to 5
  • Deliveries of supplies to be rescheduled to the two work periods
  • Would the split shift continue on cloudy and cool days or during Winter?
  • Would the portable/temporary lunch sheds now need to include a bunk room for all employees on a work site?
  • In a bunk room, would one person’s snoring becoming an occupational hazard for everyone?
  • Can plant be “paused” for the lunch break?
  • Can a concrete pour be interrupted for a lunch?

Lists of other problems or challenges are welcome through the blog’s comments field below.

Such a structural or societal control option (or fantasy) should be discussed, debated or workshopped as what may not work in the grand scheme may allow for changes, or tweaks, on a smaller scale.  Often the best OHS solutions come from speculation which can lead to the epiphany of “why do we do it that way?”

Of course, some countries are way ahead of the rest of the world in managing these workplace hazards by already having a culture that embraces the “siesta“.

ng may not be such a no-no

 

Management – the importance of what comes before

A special guest for the Safe Work Australia events in Queensland was Matthew Gill, former Beaconsfield Gold mine manager.  According to a media statement from the Government

“Matthew Gill who was the public face of the Beaconsfield mine rescue will speak about how he immediately took control of the emergency and then implemented rescue operations for the three missing miners,” [Workplace Health and Safety Queensland Executive Director, Dr Simon Blackwood] said.  “Mr Gill maintained an unwavering commitment to the safety of the people conducting the rescue and to the trapped miners.

“He oversaw the rescue teams which battled 24 hours a day for 14 days to release the two miners trapped almost 1km underground. Mr Gill will relive the emotional story of finding Larry Knight’s body and having to talk to his family afterwards.

“Previously he has been involved with mine rescue at rock falls at Mt Lyell in Tasmania and in Papua New Guinea, but Beaconsfield was the first time that he had such ‘hands on’ involvement.”

Matthew Gill has a lot of skills to share on disaster management and media handling but a lot of that skill seems to come about after the rockfall in 2006 that killed Larry Knight.

Cover KNIGHT,_Larry_Paul_-_2009_TASCD_25Prior to that time, in 1995 to 1997, Matthew Gill was the Responsible Officer for the mine.  From 1997, Gill appointed other people to undertake the role that is required by legislation.  Sometimes there were three people in the role at the same time.  Professor Michael Quinlan was quoted in the Coroner’s report saying that

“……….the very notion of appointing a Responsible Officer would have little meaning unless that person so appointed exercised overall control of the workplace and could therefore make critical decisions in relation to OHS not simply recommend them, be part of them, or make decisions but not others than might affect safety. For example, as Responsible Officer Mr Ball was a participant in decisions on mine design and mining methods – decisions that have a critical effect on the safety of underground workings – but he was not the only or final decision maker.”

The Tasmanian coroner Rod Chandler,agreed that there should be only one Responsible Officer and that the legislation be amended to reflect this.

Media reports of the inquest into Larry Knight’s death reported that after rockfalls in October 2005 and various risk consultants’ reports Matthew Gill undertook some remedial work on the mine and in February 2006, Gill declared the mine safe to restart mining.  The decisions made on the basis of those consultants’ reports came under close scrutiny in the coronial inquest.

On 10 November 2008, AAP’s Paul Carter reported the following:

Lawyer Kamal Faroque [representing the Knight family and the Australian Workers’ Union] told Coroner Rod Chandler in Launceston that Allstate’s management failures contributed to Mr Knight’s death…. Mr Faroque said mine manager Matthew Gill was ultimately responsible for deficiencies in the mine’s ground supports.  “It is submitted that deficiencies in ground support contributed to the Anzac Day rockfall which killed Mr Knight,” he said.

He also said there was no reasonable basis for Allstate to conclude that it was safe for workers to return to the area after two earlier rockfalls.

“Mr Gill accepted responsibility for the decision to recommence stoping in the western zone following the October (2005) rockfalls,” Mr Faroque said.  Stoping is a mining method in which underground chambers are opened up deep beneath the surface.

Mr Faroque said the risk management process conducted following the October 2005 rockfalls was inadequate.  “It is submitted that these failures are a sound foundation for a finding that Allstate contributed to the death of Larry Knight,” Mr Faroque told the court.

There is no doubt that Matthew Gill was integral to the successful rescue of Brant Webb and Todd Russell but Gill had been employed at the mine for over a decade before the fatal rockfall and therefore was also involved with the decision-making leading up to the rockfall.  The decisions made by the company over many years should be analysed to see the combination of bad, poor, or short-term decisions that ultimately led to Larry Knight’s death and the entrapment of his colleagues.

The rescue of Webb and Russell is an exciting tale with a happy ending and at least one book and several long articles (even a school lesson plan) have been written about this.  The most lasting lessons for safety professionals, mine managers and business operators would be what contributed to the bad decisions leading to Larry Knight, Brant Webb and Todd Russell being in an unsafe working environment during a rockfall.

This is a more complex story that requires knowledge of geology, the stock markets, corporate accountability, OHS and mine safety regulations.  If this story had been Matthew Gill’s presentation during Safe Work Australia Week, it would have been worth travelling to Queensland to hear.

Amputations, shocks and burns – court cases

In late October 2009, there were several OHS court cases in Australia that raise issues that need to be kept at the forefront of the thoughts of safety managers, safety professionals, workers and business owners.

Amputation

One case in South Australia identified the need to have sufficient detail in policies and procedures for workers to be safe.  The comment of Industrial Magistrate Michael Ardlie is particularly important.

Beerenberg Pty Ltd was fined $A9,000 dollars for breaching OHS law

“The incident happened in May 2007 at the company’s Hahndorf premises. A female employee was operating a mincer as part of the process of producing green tomato chutney.

The court was told that at the conclusion of the task, the employee switched off the machine but noticed a piece of tomato hanging from the mincer plate. She went to flick the piece off, but in doing so lost the tip of her index finger.

SafeWork SA’s investigation concluded that the woman’s finger had gone through one of the holes in the mincer plate and come into contact with the cutting blade behind, which was still winding down after the machine was switched off.

The fingertip could not be reattached, but the woman returned to work with the business after five weeks. Aside from the cosmetic appearance, there remains some numbness in the finger.

In his penalty decision today, Industrial Magistrate Michael Ardlie acknowledged that while there was a safe operating procedure written and a warning sign in place, these measures alone were insufficient.

“(The measures) did not specifically warn employees of the dangers presented by the moving parts of the mincer after the mincer had been turned off… the procedures in place did not go far enough.”

Since the incident, the company has fitted a purpose-built distance guard as well as an interlock that shuts the machine down once the guard is removed.”

Magistrate Ardlie fined the defendant $9,000 this being its first offence.

Crushed Fingers and Guarding

The same Industrial Magistrate as above, McArdlie, had to deal with a very different case.  Whereas Beerenberg was facing its first offence, OE & DR Pope are on their fifth.

“SafeWork SA prosecuted OE & DR Pope Pty Ltd after investigating an incident at its Wingfield printing plant in March 2007.

A 34-year-old male employed as a machine operator, suffered crush injuries to three fingers of his right hand, which were caught between moving rollers.  While he returned to work after three weeks, he suffered residual sensitivity problems, and left the business in December 2007 for unrelated reasons.

The court was told that the operator had attempted to clean dry spots from a roller without stopping the machine, and was able to gain access to the moving parts through a 70mm gap in the guarding.  Furthermore, the employee’s usual assistant was not available leaving him to perform two roles on the machine.  The supervisor who also should have been present was elsewhere on the premises at the time.

In his decision on penalty handed down today, Industrial Magistrate Michael Ardlie noted that the machine involved had replaced another involved in a previous injury, but that a risk assessment failed to identify the problem which ultimately occurred:

“Whilst the defendant prior to the incident did assess the machine, installed a guard and introduced a Standard Operating Procedure, the steps it took were inadequate.”

The court was told that this was the company’s fifth offence dating back to 1998, and all previous incidents resulted in similar injuries from similar circumstances.

Therefore, being a subsequent offence under the Occupational Health Safety and Welfare Act 1986, the defendant faced a maximum fine of $A200,000. Magistrate Ardlie fined the company $A40,000.”

Fifth incident in just over ten years – “similar injuries from similar circumstances”.  The reduced fine of $A40,000 seems a little odd in this context.

There are several elements that are disturbing in this case – ineffective guarding, excessive or conflicting workload and absent work supervisor.

Overhead Hazards

Just as falling in some workplaces is as “easy as falling of a log”, so it is that many people forget to look up.  A court case in Western Australia has fined Shrigley Drilling Contractors $A40,000 after one worker was shocked and another burnt when their drilling rig tilted into high-voltage overhead powerlines in 2006.

“Laurence Victor Shrigley – trading as Shrigley Drilling Contractors – pleaded guilty to failing to ensure that the workplace was safe and, by that failure, causing serious harm to another person and was fined in the Perth Magistrates Court this week.

In May 2006, Western Power had contracted Outback Power Services to perform works and construct a voltage regulator at Eneabba. Outback Power had contracted Mr Shrigley to perform drilling works.

On May 17, Mr Shrigley and an electrical contractor were engaged in drilling holes with a drilling rig underneath power lines. The position in which the drilling contractor chose to place the rig required him to raise the mast very close to the power lines.

In repositioning the rig, the left-hand outrigger was raised and the mast tilted towards the power lines. The mast touched the power lines and Mr Shrigley received an electric shock and was thrown backwards from the drilling rig.

Another man, who was driving the truck that carried the drilling rig and was working with Mr Shrigley on a voluntary basis, also received an electric shock serious enough to set his clothing on fire. He sustained burns to around 60 per cent of his body.

The court heard that no formal pre-start meeting had been held before the work commenced, and no directions were given for the work, with the exception of where the holes were required to be placed.

Mr Shrigley had not checked whether the power lines were live, or attempted to make any arrangements for the power in the area to be isolated.”

The features in this case include contractor management, using a volunteer,  inadequate preparation, and inadequate number of workers (apparently, no spotter).

It is understandable that cynicism is rampant in the safety profession when the same work practices lead to injuries in the 21st century just as they did in the 20th and sometimes in the 19th.

Workplace falls continue even during a safety week

Several years ago while visiting a local council with an OHS mentor, a call came through that a worker had fallen over 10 metres through a skylight into a plant room at a commercial swimming pool.  It was the first time I had been on site shortly after a workplace incident and was party to the negotiations and advice between OHS advisers, health & safety representatives and quickly after the event, the CEO.

I am reminded of that day too often when reports come through of workplace falls and deaths.  Workplace incidents do not take a holiday even during Safe Work Australia Week and this year was no different.  Below are a couple of short reports of incidents from last week.  As they did not result in a death, they were unlikely to be reported in the mainstream press.

“A man has fallen through a warehouse roof, dropping eight metres onto concrete at Brunswick [on 30 October 2009].

‘The 24 year old man landed on the concrete and some bicycles that were on the floor,’ according to Intensive care paramedic Kate Cantwell. ‘Even though he had fallen about eight metres, he is extremely lucky that he landed on his arm and side, and not on his head. He has quite a severe fracture to his arm, and possibly a fractured pelvis.”

“A 62-year-old man fell nearly three metres to the ground when he slipped off a ladder in Heidelberg Heights [on 26 October 2009].  Advanced life support paramedics from Oak Park and Epping were called to the residential building site at 11.05am.

Paramedic Haley McCartin said they arrived within eight minutes to find the man lying on the ground in a significant amount of pain.  ‘He suffered a suspected fractured hip and wrist,’ she said.”

Both these cases were posted by the Ambulance Service in Victoria and reinforce that falls in workplaces continue to occur.  Not all falls cause death but falls invariably result in serious injuries.

It is fair to say that gravity continues to be the number one contributory factor to workplace falls.

Gov’t responds to insulation installer’s death

Recently SafetyAtWorkBlog reported of the death of a worker installing insulation in a domestic home.  A staple for the foil insulation apparently pierced an electrical cable and electrocuted the worker.

The Queensland Government has introduced mandatory provisions to avoid the hazard in the future.  In a media release on 1 November 2009, the Industrial Relation Minister, Cameron Dick,

“… issued a ministerial notice under the Electrical Safety Act 2002 to prohibit the use of metal fastenings for ceiling insulation.”

The ban is effective from 1 November 2009.

It may already be the case, elsewhere in the world, that non-conductive fasteners are used for installing metallic insulation.  If not, the rules introduced by the government should prove useful references.

“The ministerial notice means that installers will have to use nylon or plastic fasteners (which are already in use within the industry), glue or tape to fix foil insulation in ceilings.

As well as banning metal fasteners, the notice also:

  • forces insulation installers to comply with the Wiring Rules with respect to the placement of any type of insulation near recessed downlights
  • makes electrical safety risk assessment training mandatory for all installers
  • forces installers to document their on-site electrical safety risk assessments and keep a record f or five years.”

Such a mandatory rule is clearly a necessary short-term fix but it does little to address the concerns of the Master Electricians Association.  Training and enforcement are the long-term solutions but policymakers must also anticipate the applications of their policies more closely.  New policies should not be announced in an industry that does not have the resources to meet the policy’s aims.

Grandad’s disease

Almost as a follow-on from the Matt Peacock podcast the UK’s Health and Safety Executive has given asbestos the feature slot in its October 2009 podcast that has just been released.

The podcast and accompanying campaign is aimed at the recent tradespeople who may be under the impression that, as asbestos was banned in the UK in 2000, that the hazard no longer exists.  This is not the case and the podcast pushes this point.

The podcast also mentions how people panic when  there is any risk of exposure to asbestos.  Strangely, the speakers say that harm from asbestos is more likely to come from prolonged exposure than from a single fibre.  This seems to contrast with the asbestos campaigns of the past and given that symptoms of asbestos-related diseases can appear “out-of-the-blue” decades later, the statement sounds odd.

Revealing podcast on asbestos in Australia

On 15 October 2009, Matt Peacock, a journalist with the Australian Broadcasting Corporation and author of a new book on asbestos and the James Hardie company, “Killer Company: James Hardie Exposed” spoke publicly at Trades Hall in Victoria.

Killer Company cover 001Peacock has allowed an edited version of his presentation to be used as a SafetyAtWork podcast which can be downloaded.  In the podcast he discusses the conduct of the James Hardie boss of several decades, John B Reid; the pervasive nature of asbestos throughout the Australian community; the surveillance of opponents by the company; the immoral public relations campaigns and, generally, the conduct of a corporation that knowingly sold a product that was toxic and harmful.

One blogger reviewed the book and said

“Killer Company” clearly shows that JH directors were criminally negligent and showed no humanity or compassion for their victims and no remorse for their crimes.

Peacock produced several reports on asbestos recently.  Video and transcripts of his reports can be accessed HERE.

Peacock has also been interviewed extensively about his book.  A video interview is available HERE
