Reflections on Safety: Reasonably Practicable

In August 2016, I wrote a WHS Update about the High Court decision, Deal v Father Pius Kodakkathanath [2016] HCA 31 which considered the legal test of Reasonably Practicable in the context of Australian health and safety legislation. Shortly after that, one of my connections on Linkedin posted an article about Reasonably Practicable. The article offered an engineering perspective on “As Low as Reasonably Practicable” (ALARP), stating:

… recent developments in Australian workplace health and safety law place proactive responsibilities on senior personnel in organisations, so they must be fully informed to make proper decisions

This sentiment seemed similar to an earlier engineering publication which argued that ALARP and “So Far as is Reasonably Practicable” (SFARP) were different and that this difference was, in part a least as result of “harmonised”, WHS legislation.

In both cases, I believed the articles were misaligned with the legal construct of Reasonably Practicable and misrepresented that there had been a change in the legal test of Reasonably Practicable prompted by changes to WHS legislation.

This background caused me to reflect again on the notion of Reasonably Practicable and what it means in the context of legal obligations for health and safety.

To start, I do take issue with the suggestion that changes to WHS legislation have resulted in a shift in what Reasonably Practicable means. The basis of this idea seems to be an apparent change in terminology from ALARP to SFARP.

The term SFARP was in place in health and safety legislation before the introduction of WHS and jurisdictions that have not adopted WHS legislation still use the term. For example, the primary obligations under the Victorian Occupational Health and Safety Act 2004 are set out in section 20, and state:

To avoid doubt, a duty imposed on a person by this Part or the regulations to ensure, so far as is reasonably practicable, health and safety requires the person …

Indeed, the architects of WHS legislation[1] specifically retained the term Reasonably Practicable because it was a common and well-understood term in the context of Australian health and safety legislation:

5.51 Reasonably practicable is currently defined or explained in a number of jurisdictions. The definitions are generally consistent, with some containing more matters to be considered than others. The definitions ‘are consistent with the long settled interpretation by courts, ‘in Australia and elsewhere.

5.52 The provision of the Vic Act relating to reasonably practicable was often referred to in submissions (including those of governments) and consultations as either a preferred approach or a basis for a definition of reasonably practicable.

5.53 We recommend that a definition or section explaining the application of reasonably practicable be modelled on the Victorian provision. We consider that, with some modification, it most closely conforms to what would be suitable for the model Act.  [My emphasis added]

In my view, it is unarguable that the concept of Reasonably Practicable has been well-settled in Australian law for a considerable period, and the concept has not changed with the introduction of WHS legislation.

If we accept that Reasonably Practicable has been consistently applied in Australia for some time, the next question is, what does it mean?

Reasonably Practicable is a defined term in most health and safety legislation in Australia.  Section 20(2) of the Victorian Occupational Health and Safety Act 2004, for example, states:

(2) To avoid doubt, for the purposes of this Part and the regulations, regard must be had to the following matters in determining what is (or was at a particular time) reasonably practicable in relation to ensuring health and safety—

 (a) the likelihood of the hazard or risk concerned eventuating; 

 (b) the degree of harm that would result if the hazard or risk eventuated; 

 (c) what the person concerned knows, or ought reasonably to know, about the hazard or risk and any ways of eliminating or reducing the hazard or risk; 

 (d) the availability and suitability of ways to eliminate or reduce the hazard or risk; 

 (e) the cost of eliminating or reducing the hazard or risk.

In the High Court decision, Slivak v Lurgi (Australia) Pty Ltd [2001] HCA 6, Justice Gaudron described Reasonably Practicable as follows:

The words “reasonably practicable” have, somewhat surprisingly, been the subject of much judicial consideration. It is surprising because the words “reasonably practicable” are ordinary words bearing their ordinary meaning. And the question whether a measure is or is not reasonably practicable is one which requires no more than the making of a value judgment in the light of all the facts. Nevertheless, three general propositions are to be discerned from the decided cases:

• the phrase “reasonably practicable” means something narrower than “physically possible” or “feasible”;
• what is “reasonably practicable” is to be judged on the basis of what was known at the relevant time;
• to determine what is “reasonably practicable” it is necessary to balance the likelihood of the risk occurring against the cost, time and trouble necessary to avert that risk.[2] [my emphasis added]

Another High Court decision, Baiada Poultry Pty Ltd v The Queen [2012] HCA 14, emphasised similar ideas.

The case concerned that the death of a subcontracted worker during forklift operations.  Baiada was the Principal who had engaged the various contractors to perform the operations and in an earlier decision the court had concluded:

it was entirely practicable for [Baiada] to required contractors to put loading and unloading safety measures in place and to check whether those safety managers were being observed from time to time ((2011) 203 IR 396 at 410)

On appeal, the High Court framed this finding differently.  They observed:

As the reasons of the majority in the Court of Appeal reveal by their reference to Baiada checking compliance with directions it gave to [the contractors], the question presented by the statutory duty “so far as is reasonably practicable” to provide and maintain a safe working environment could not be determined by reference only to Baiada having a legal right to issue instructions to its subcontractors. Showing that Baiada had the legal right to issue instructions showed only that it was possible for Baiada to take that step. It did not show that this was a step that was reasonably practicable to achieve the relevant result of providing and maintaining a safe working environment. That question required consideration not only of what steps Baiada could have taken to secure compliance but also, and critically, whether Baiada’s obligation “so far as is reasonably practicable” to provide and maintain a safe working environment obliged it: (a) to give safety instructions to its (apparently skilled and experienced) subcontractors; (b) to check whether its instructions were followed; (c) to take some step to require compliance with its instructions; or (d) to do some combination of these things or even something altogether different. These were questions which the jury would have had to decide in light of all of the evidence that had been given at trial about how the work of catching, caging, loading and transporting the chickens was done.[3] [my emphasis added]

In light of these, and other decided cases it is possible to form a practical test to consider what is Reasonably Practicable.  In my view, it is necessary for an organisation to demonstrate that they:

• Have “Proper Systems” to manage the health and safety risks in their business; and
• Exercise “Adequate Supervision” to ensure that the Proper Systems are implemented and effective to manage the risks.

What constitutes Proper Systems and Adequate Supervision is a judgement call that needs to be determined with regard to the risks.  It requires an organisation to balance the risk against the cost, time and trouble of managing it.[4]

It is also worth noting at this point, that Reasonably Practicable is, generally speaking, an organisational obligation.  It is not an individual,[5] and in particular, it is not an employee obligation.

I often see, when working with clients, safety documents required be signed by employees that the state that risks have been controlled to “ALARP”.  This is not the employee’s responsibility and the extent to which an employee does or does not control the risk to ALARP does not affect an employer’s obligations.

In broad terms, it is the organisation’s (PCBU or employer) obligation to manage risks as low as, or so far as is, Reasonably Practicable.  The employee obligation is to do everything “reasonable”.  This includes complying with the organisation’s systems.

It is the organisation’s obligation to identify the relevant health and safety risks and define how they will be controlled, ensuring that the level of control is “Reasonably Practicable.  It is the employee’s obligation to comply with the organisation’s requirements.

So, what might Reasonably Practicable look like in practice?

I recently defended a case that involved a worker who was seriously injured at work.  Although the injury did not result from a fall from height, the prosecution case against my client was based on failure to meet its obligations about working at heights.

My client had, on any measure, a Proper System for managing the risk of work at heights.  They had a documented working at height Standard and Procedure both of which were consistent with industry best practice and regulator guidance material.  All work at height above 1.8 m required a permit to work and a JHA.  The documented procedures prescribed appropriate levels of supervision and training.

In the three years before the relevant incident, my client had not had a working at height incident of any sort nor had they had a health and safety incident at all.  Based on all of our investigations as part of preparing the case, there was nothing to suggest that the incident information was not legitimate.

The activity which was being performed at the time of the incident was conducted routinely, at least weekly, at the workplace.

In looking to construct a Reasonably Practicable argument to defend the case what would we be trying to do?  In essence, I would be trying to establish that the incident was an aberration, a “one off departure” from an otherwise well understood, consistently applied system of work that was wholly appropriate to manage the risk of working at heights.

In practice, that would mean:

• Producing statements from all of the workers who performed this task describing how it was performed in practice, and demonstrating that their understanding of the way the work was performed in practice was consistent with the requirements of the organisation’s documented systems;
• Producing completed documentation from when the job had been performed previously, and demonstrating that the documentation was consistent with the organisation’s requirements, and completed correctly;
• Producing statements from supervisors who approved the documentation and oversaw the performance of the work and demonstrating that their understanding of the way that the work was performed in practice was consistent with the requirements of the organisation’s documented systems;
• Producing completed documentation from when the injured worker had performed the work previously and demonstrating that the documentation was consistent with the organisation’s requirements and completed correctly.

There may be other information that we would seek, but in broad terms, the information outlined above helps to build a case that there was a proper system that was effectively implemented and that:

• All the workers understood the system,
• All the workers understood how it ought to have been applied, and
• It was applied in practice.

What happened?

Rather than be able to demonstrate that the incident was a one-off departure from an otherwise effective system, the evidence revealed a complete systemic failure.  While the documented system was a Proper System and complied with all relevant industry standards and guidelines, it was not implemented in practice.

Most compelling was the fact that, despite this being a weekly task, there was not a single instance of the working at height Standard and Procedure been complied with.  We could not produce a single example where either the injured worker or indeed any worker who had performed the task had done so under an approved permit to work with an authorised JHA.

All of the workers gave evidence that the primary risk control tool on site was a Take 5.  The Take 5 is a preliminary risk assessment tool, and only if that risk assessment scored 22 or above was a JHA required.  The task in question was always assessed as 21.  The requirement for a JHA, in the minds of the workforce, was never triggered and none of them understood the requirements of the Standard or Procedure.

To me, this case is entirely indicative of the fundamental failure of Reasonably Practicable in most workplaces.  In the vast majority of cases that I have been involved in the last 25 years, organisations have systems that would classify as Proper Systems.  They are appropriate to manage the risk that they were designed to manage.

Equally, organisations cannot demonstrate Adequate Supervision.  While there may be audits, inspections, checking and checklists – there is no targeted process specifically designed to test and understand whether the systems in place to manage health and safety risks in the business are in fact implemented and are effective to manage those risks.

In my experience, most organisations spend far too much time trying to devise the “perfect” Proper System.  We spend far too little time understanding what needs to be done to confirm that the System works, and then leading the confirmation process.

Reasonably Practicable has not changed.

Reasonably Practicable is not a numeric equation.

Reasonably Practicable changes over time.

Reasonably Practicable is an intellectual exercise and a judgement call to decide how an organisation will manage the health and safety risks in its business.

Reasonably Practicable requires an organisation to demonstrate that they:

• Have “Proper Systems” to manage the health and safety risks in their business; and
• Exercise “Adequate Supervision” to ensure that the Proper Systems are implemented and effective to manage the risks.

What constitutes Proper Systems and Adequate Supervision is a judgement call that needs to be determined with regard to the risks.  It requires an organisation to balance the risk against the cost, time and trouble of managing it.
