Women engineers need plenty of courage

Australian Financial Review

There are many opportunities for women wanting to become engineers, but they need to be fearless about being the only woman in the room.

Dr Annalisa Contos speaks to the Australian Financial review about the challenges and rewards of a career in engineering.

Setting control limits statistically ensures that data that requires attention is highlighted to the operator to ensure action can be taken to prevent breach of CCPs or licence limits and allows continuous improvement over time.

Water quality studies on the 148 km B-section pipeline including the development of P&IDs, an EPANET model and chlorine decay studies investigated improvements to the systems. Operational risk associated with the installation of a new rechlorinator  were assessed and mitigation measures developed.

Global Water Pathogen Project

Dr Annalisa Contos, Natalie Crawford

This case study examined whether public health risks from a local government operated recycled water scheme were appropriately managed through treatment and non-treatment barriers (end user controls). The pathogen log10 reduction requirements for recycled water for a mix of uses including food crop and municipal irrigation were determined. The four recycled water plants were verified to assess if they were meeting these requirements and whether the non-treatment barriers (end user controls) were adequate

Kamal Fernando Memorial Lecture Institution of Engineers Sri Lanka, NSW chapter

Dr Annalisa Contos

Human error is often cited as root cause of incidents and accidents. In this talk Dr Contos introduces key topics within the field of human factors. The talk addresses the environmental,  organisational and job factors as well as human and individual characteristics, which influence behaviour at work in a way which can affect health and safety. Drawing from examples in the water industry Dr Contos discusses how human factors are important to both process and product safety.

Information Sheet

This information sheet explains how threat-consequence or bow-tie diagrams can be used for visual risk analysis. Bow tie diagrams describe the pathways of a risk from its cause to its consequence and illustrate the barriers in place to reduce the risk (ISO/IEC 31010, 2009). The strength of bow-tie diagrams is that it goes beyond the usual risk assessment ‚Äėsnapshot‚Äô and highlights the links between the threat, its consequences, the barriers preventing the consequence from occurring and the strengths of these barriers. In its full application it can be used to demonstrate the linkages between the barriers and the underlying management system. The highly visual nature of the diagrams are well-suited to communicating risk issues to non-specialists.
