Hi Tom, Michael, Martin, and James,
Thank you all for your thoughtful reflections. It's inspiring to see this conversation unfold because it touches on the very heart of what makes engineering such an important profession. I believe engineers bring a unique and essential two-pronged contribution to safety:
-
Our technical and systems knowledge across the full asset lifecycle, and
-
Our ethical obligation to protect life, property, and the environment.
First, our technical training allows us to think holistically, not just about isolated hazards but about how systems behave over time - through design, construction, operation, and and decommissioning. We understand how materials fatigue, how people interact with systems, and how design decisions made early on can either build resilience or embed latent risks. This systems perspective allows us to create environments where safety is engineered in - not bolted on as an afterthought.
Second - and equally important - our professional ethics compel us to advocate for the protection of life and well-being, even when this conflicts with short-term commercial pressures. Engineers are not just technical experts; we are stewards of societal trust.
I would also like to build on Martin's important point regarding the hierarchy of controls.
While many focus on administrative controls and PPE once risks materialise on the frontline, engineers have a unique opportunity to intervene much earlier - through influencing investment decisions related to systems and infrastructure. By influencing feasibility planning, front-end design, detailed design and procurement choices, we can pursue elimination and substitution strategies that remove or reduce hazards before they ever reach workers or the public.
For example, selecting inherently safer materials, automating hazardous processes, or designing infrastructure to withstand extreme events are all ways that engineers can shift safety outcomes decisively. These decisions often require strong technical analysis combined with ethical leadership - weighing not just what is cheapest or fastest, but what protects people and future-proofs the system.
In this sense, engineers sit at the critical junction between technical possibility and ethical responsibility. When we embrace our dual identity - as technical custodians and ethical advocates - we amplify our impact far beyond compliance, contributing to a safer, more resilient world.
Thank you again for initiating this important discussion. Conversations like these remind me why I am proud to be part of this profession.
Best regards
Laurie Bowman

A very nice case study, thanks Martin. I have archived a copy.

Hi Tom / Michael / James
I thought I would attach a practical example of how I try and communicate the interaction (in the built environment) between the responsibilities / capabilities of the design engineer and the end user. This example refers to minimizing respirable crystalline silica dust emissions during building.
kind regards
Martin

Within the Engineered Safety Group we have discussed for years the role of engineers in keeping people from harm. We single out things like safe design and the use of safety processes with an engineering context that improve safety for workers and the public. Architects, medical staff and safety professionals can positively impact safety of course, but engineers, through the use of maths and sciences, bring a different approach to both personal safety and process safety.
We are interested in what other engineers think about this topic? In your experiences, what are the special things, attitudes, thinking processes or even behaviors do engineers bring to the safety table that other disciplines or professions do not?
