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

 

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.

Prosecution results from fall through roof

On 22 October 2007, a commercial premise in Southbank, Victoria, was to undergo renovations which included replacing the asbestos roof with an iron roof.   Two men were employed as project managers and during the roof replacement, according to WorkSafe Victoria.

“…the dogman fell [through an unguarded shaft] a total distance of 8 metres and as a result he broke 3 bones of his right wrist and a fractured scapula as well as sustaining bruising to the body and serious lacerations to the head.”

On 16 October 2009, the Magistrates’ Court fined the specialist roofing company contracted for the task $A15,000.  The prosecution summary says that as the company specialised in roofing, the hazards of working on an asbestos roof, and unprotected edges, would have been well-known.

The two project managers were fined $A7,500 each as they were not sufficiently experienced for their project management roles.  The lack of fall protection for those working on the roof was of particular note according to the Prosecution Summary from WorkSafe Victoria.

More details on the prosecution are available from the WorkSafe hyperlinks in this article.

It would be interesting to run this prosecution summary as a hypothetical under the proposed National OHS Model law to provide a contrast between the old and new laws particularly on the following matters, although many more could be considered if further details were available:

  • who controls the workplace
  • competence
  • suitably qualified
  • role and enforcement of JSA’s
  • contractor management

Road worker seriously injured at worksite

The Ambulance Service of Victoria, Australia reported the injury to a roadside worker on 19 October 2009.  Below is part of their report:

A road worker is in a serious condition after being hit by a car in a road works area this morning.

Advanced life support paramedics from Jackson’s Creek were called to Derby Street in Pascoe Vale at 11.40am.  Paramedic Chris Collard said they arrived within six minutes to find the man lying on the road being helped by an off duty nurse.

‘It appeared the car had been driven into the road works area and hit the man,’ he said. ‘The 33-year-old man suffered a head injury, deep cut to the back of his head and some leg pain…. We encourage drivers to slow down while driving through road works, obey the signs and be wary of the workers on the road.’

Working only a metre or two from traffic, even in a domestic area, like the case above, presents well-known hazards, at least well-known to the workers.

WorkSafe Victoria undertook an education campaign on the issue several years ago.  The remaining website continues some good information although it is a little out-of-date.

In 2005, the Roads and Traffic Authority in New South Wales reported

“… there were 603 crashes at roadwork sites in NSW.  Ten people were killed and 356 were injured.  Injuries to road workers in NSW cost more than $100 million a year, but the financial and human toll could be much lower if drivers slowed down and observed road work speed limits.”

In around 2006, the Highways Agency in the UK began a short campaign on improving the safety of roadworkers,  Some background and the action plan is available online.  As with many government campaigns and plans, it is difficult to quantify the success.

Comments from a spokesperson for the Minister for WorkSafe, Tim Holding, in 2005 illustrate the dominant political position on anything related to road safety be it level crossings or roadworker safety – change behaviour and save the world – and yet behaviour is probably the hardest (and costliest) element in this equation to change :

“…people should stay within posted speed limits. “. . . people should concentrate at driving at or below the speed limit and . . . spend less time worrying about how many kilometres they can drive over the speed limit without getting fined…,”

In 2005 there was a minor political kerfuffle when it was revealed that speed cameras could not be recalibrated to lower speeds for application in roadwork sites.

From experience, Australia is yet to use the portable traffic light systems widely that have been applied in the UK for decades and yet the advantages are that it formally establishes buffer zones, removes flagmen from the role of frontline control and builds on a cognitive language that almost everyone has retained from early childhood – the red, amber, green signage.

Changing weather conditions can present unexpected hazards

In the south-east corner of Australia, a drought has existed for over a decade.  This week in Melbourne, it has rained on and off for several days, changing the way the community is feeling.  Farmers are happy, owners of rain water tanks are happy, gardeners are happy, even commuters who have to relearn how to drive in the wet are less complaining.

Some months ago, I spoke to a mother whose two-year-old daughter had never seen a heavy rainstorm, thunder or lightning.  Early last year, a colleague and I looked out of an office building window on a 13th floor and saw smoke swirling round the city.  It turned out to be rain but we had not seen rain for so long that we mis-identified it.

This morning, I was removing money from an automatic teller in the street and I was dripped on from the leaking roof of the bank for the first time ever.  A local chemist had buckets on its floor to catch drips from the ceiling that they had never seen before.

Yesterday, 15 October 2009, a concrete pumper at a housing development site in Coburg sunk in some mud just enough to swing the pump’s hose into a worker, killing him.  Other media reports say that a stand of the pumper may have malfunctioned.

There are always many lessons from workplace deaths but one to be taken from this incident is that external factors to the actual tasks in hand must be considered.  Those factors, in this case weather and soil stability, can change within a work period and this variability of environment must be watched and anticipated.

Mud on a construction site is not a new hazard.  But if a hazard is not always  present or regularly encountered, it is easy to give it less attention.

Who is advising John Holland?

The person, Sir John Holland, died in May 2009.  The company, John Holland Group (JHG), is in danger of a shortened life if it continues to make bizarre decisions.

John Holland Group has been widely criticized by the union movement, principally for its decision to jump out of State OHS jurisdictions to the Commonwealth (Comcare) structure.  This was seen as a purely financial response to a politically sensitive  opportunity that was presented by the Liberal government of then-Prime Minister John Howard.  Comcare was seen as the insurer of the defence forces and public servants and, unions claimed, enforcement of OHS to an acceptable level was beyond the skills and resources of the administrative agency.

Due to union pressure, John Holland Rail was dropped from the finalists for a national safety award in early 2009.  JHG probably came in for more criticism than other companies who also jumped because it is in the highly-unionised construction sector and their construction work is so public.

One of the advantages of moving to the Federal OHS scheme was that any prosecutions would occur in that jurisdiction and JHG has been prosecuted there.  JHG had several OHS breaches in 2005 and 2006.  It came under the Federal OHS law in March 2007.  In September 2008, Worksafe Victoria charged the company over one of the 2006 breaches.

According to a report in The Age on 14 October 2009, JHG

“issued a High Court challenge, claiming the charges were ”incompetent” because it was not liable for conviction under Victorian workplace law for offences committed before it came under the Commonwealth jurisdiction.”

John Holland v Vic Workcover Authority  John Holland v Ins_High Court challenges are not cheap and the wisdom of the decision to contest the State actions was always questionable, doubly so now the High Court unanimously decided against JHG’s arguments.

The High Court challenge confirmed for many the impression that John Holland Group will try to avoid safety obligations, if possible, and that the move to a “softer” regulatory scheme was one of the reasons behind the move to the Comcare scheme.  The legal action undermines all of the positive safety culture messages that the corporation has issued.

JHG is involved with many new infrastructure and construction projects.  Harmonised OHS laws are set for 2011 which include the federal OHS laws under which Comcare operates.  Within a decade of taking up an opportunity for a “softer” regulatory regime, the advantage may be gone and the John Holland Group Board should ask themselves “was it worth it?”

Business commentator is concerned over OHS and IR overlap

Respected business commentator, Robert Gottliebsen, has commented on the political and ideological challenge that Julia Gillard, Australia’s Minister for Workplace Relations, faces over the introduction of OHS model legislation.

Gottliebsen says there is a risk that the combative OHS structures in New South Wales could spread to the national context and that resisting this movement, funded and promoted by the trade unions, will be a substantial test for the Minister. In his Business Spectator article he says

“To make it tougher for Gillard, the draft [legislation] has clauses that will give unions around Australia NSW-style prosecution powers and clauses that water down training requirements.  This will mix IR issues and safety and may well increase the injury rate.”

There is a persistent debate about the IR context of OHS and vice versa, which is the tail and which is the dog.  Gottliebsen clearly sees the NSW experience as illustrating IR having too much influence over OHS management.  (For those readers outside Australia, NSW is seen widely as a failure economically and politically)

“The sad thing is that once occupational healthy and safety becomes merely a tool of industrial relations, it is politicised and linked to wage claims and is not taken seriously.  More workers go home injured or worse.  So not only do we need English-style law, but we need law that isolates safety from industrial relations skirmishes.”

This is reminiscent of the days when industrial employment awards provided allowances for dangerous or unhealthy tasks, what was universally considered “danger money”.

Robert Gottliebsen is no fool and the significance of his article is the fact that the issue was covered by a finance and business commentator at all.  It indicates the significance of what the Federal Government is proposing, politically, industrially and socially.  the foundations of OHS legislation have remained basically the same since Lord Robens’ recommendations in England in the 1970’s.  Australia has had OHS legislation since the early 1980’s.  The new model OHS legislation should similarly be seen in such longevity and broad impact.

OHS may be a niche consideration for most people but how the government handles the negotiations leading to this law’s implementation will be a good indication of their political nous and their commitment to Australians.
