    Dr Dirk Pons of the Department of Mechanical Engineering at the University of Canterbury, Christchurch, and member of our executive committee, recently published the following article: Alignment of the Safety Assessment Method with New Zealand Legislative Responsibilities


    Need—National legislative health and safety (H&S) frameworks impose requirements but grant self-management to organisations. Consequently variability arises in management systems, and some organisations struggle to achieve successful implementation. The risk assessment process is key to the H&S management system, and could benefit from greater consistency and better external alignment with the legislative framework of the jurisdiction.

    Approach—The harm categories in the New Zealand (NZ) Act were adapted into a consequence scale. A non-linear scale was developed for the consequence axis to represent the disproportional nature of catastrophic harm outcomes compared to minor injuries. A hazard assessment process was devised based on systems engineering methods. Organisational decision-criteria were derived from the communications requirement in the Act, and these thresholds linked to expected treatments.

    Originality—A method is providing for aligning risk assessments with a national legislative framework, and integrating the technical aspects of risk assessment with the management processes. The approach also more explicitly includes recovery actions in contrast to existing methods where prevention dominates. Regarding the management aspects, it shows how thresholds may be defined relative to the legislation, to give clear expectations regarding treatment and internal communication, thereby assisting executives (‘officers’ in terms of the NZ Act) meet their duties.

    I have a PhD student who is interested in combining PLANT SIMULATION with SAFETY ENGINEERING. If you have suggestions for topics or firms that might be interested in learning more, please get in touch.

    Plant simulation is software modelling that creates a digital model of manufacturing/transport. It mathematically represents machines and humans, and includes variability in processes to determine production statistics.  See

    MBIE is reviewing some of the regulations that sit under the Health and Safety at Work Act 2015.

    Here is a link to their OVERVIEW - Implementing the HSWA 2015 - Better-regulation plant structures and working at heights

    The full paper is accessible here: Disscussion paper on options to improve regulations for work involving plant, structures, heights and excavations.

    We have been invited to work with MBIE and to  provide our views on their proposals.

    Members, please log in to this web-site and join the discussion on our members-only forum.

    From Worksafe's Media Release dated 1 May 2019:

    "A scaffolding company has been fined $150,000 after a poorly designed scaffold collapsed while seven people were working on it.

    Affordable Scaffolding (2010) Limited was sentenced at the Auckland District Court last month following the February 2017 incident involving a scaffold erected under the Panmure Bridge in Auckland. The scaffold collapsed while seven workers were completing maintenance work on the bridge. Six workers fell into the water and another was trapped on the scaffolding. No-one was seriously injured.

    A WorkSafe investigation found the collapse occurred due to overloading. It found Affordable Scaffolding (2010) Limited failed to ensure scaffolding was designed safely and load calculations and design drawings were not reviewed by an engineer prior to the scaffold being built."

    Breaking free. The Royal New Zealand Navy's largest ever vessel Aotearoa was formally ‘launched’ last week. Overseen by the Chief of Navy, Rear Admiral David Proctor, the ship lifted off the blocks as the dry dock opened and the sea flooded in.

    I am happy to announce that Stuart Wright, Principal Engineer, Health and Technical Services at WORKSAFE has been appointed as ex-officio committee member to the NZSSE.

    We welcome Stuart to our ranks and we hope that we can work together to achieve great results in the Safety Engineering field.

    Stuart takes over from Geoff Connor who has taken up a role at the New Zealand Space Agency. We wish Geoff the very best in his new role and thank him for his service to the NZSSE and the greater cause.
