Are we really going to intentionally ignore the new Australian Standard AS5327:2019?
Paul Dean | Founder, Technical Director
The short answer is, yes we are. The reason why is set out in the slightly less short answer below.
After a long time in the draft, comment and review phases AS5327:2019 Earth-moving machinery – Access Systems was released on the 29th of July 2019.
AS5327:2019 is as I mentioned in previous articles a modified version of ISO2867:2011 Earthmoving Machinery – Access Systems. My previous articles (see links below) have focused on the differences between the draft Australian standard and ISO2867:2011 as well as one other differences between ISO2867:2011 and ISO14122-3:2016 Permanent means of access to machinery – Stairs, stepladders and guardrails.
The main focus has been the height above the ground or nearest platform at which a platform requires a guardrail. The draft version of AS5327 required guardrails on platforms above 1m from the ground or nearest platform.
The newly published Australian Standard AS5327:2019 has changed to be in alignment with ISO2867:2011 by requiring a guardrail on platforms above 2 or 3m depending on the distance from the edge of the walkway/platform to the edge that you can fall from.
The 2 or 3m height is in stark contradiction to AS4024-1201:2014 General principles for design – Risk assessment and risk reduction which is identical to ISO14122-3:2016 Permanent means of access to machinery – Stairs, stepladders and guardrails which require a guardrail on any platform above 0.5m.
The relevant extracts from each standard are below.
AS5327:2019 & ISO2867:2011 state the following –
AS4024:2014 & ISO14122:2016 state the following –
WHS laws weigh in on the management of risk from falls as well. Regulation 78 & 79 of the WHS Regulations require that a person conducting a business or undertaking manage the risks to health and safety associated with a fall by a person from one level to another. These regulations talk about risks and suggest risk controls but do not specify the exact risk control.
It is important to note that Regulation 78 & 79 are laws where as all of the standards referenced are guidelines. Guidelines are there to help us determine what compliance could/should look like.
In summary there are 3 relevant pieces of information for consideration –
- AS5327 & ISO 2867 which are both specific to earthmoving machinery require guardrails above 2 or 3m
- AS4204 & ISO14122 which are applicable to all machinery require guardrails above 0.5m
- Regulations 78 & 79 require the most practicable risk control to be in place, which is a guardrail in most circumstances, but do not specify a height
So the question then becomes – How do we reconcile these 3 pieces of information, particularly the obvious contradictions between the standards?
The answer lies in the risk assessment process. The risk assessment process has 4 steps –
- Identify hazards
- Assess the risk – consequence vs likelihood
- Control the risk – hierarchy of risk control
Plant Assessor uses this process, in particular steps 2 & 3 to determine how to apply the available information from the various laws, standards, codes of practice and so on to each machine.
As a result of our interpretation of the available information and our application of the risk assessment process from August 26th 2019 onwards Plant Assessor will require all platforms above 0.5m from the ground or nearest platform on all machines that may have such a platform to have a guardrail unless certain criteria can be constantly maintained.
The new question will be –
Do all operator work platforms that are either –
a. above 0.5m and below 2.0m from the ground or nearest platform, where three points of contact cannot be constantly maintained by any person
on the platform performing expected tasks or
b. above 2.0m from the ground or nearest platform
have an approved handrail that meets the following requirements:
- All handrails are at least 1.1m high
- All handrails have a mid rail
- All sides and ends have a kick plate which is at least 100mm high?
(answer n/a if there are no platforms where the operator’s feet are above 0.5m & below 2.0m where a constant 3 points of contact is possible during access performing expected tasks)
The constant three points of contact requirement allows for operators checking fluid levels etc on machines such as motor graders where the operator’s feet may be in excess of 0.5 m above the ground, however three points of contact can be maintained because the operation is a single handed operation. An appropriate hazard warning label should be adjacent to advise that 3 points of contact is required in these areas.
