New engineering drawings and CAD requirements standard Potential benefits Consistency across transport organisations in TfNSW cluster ✓ Alignment with AS1100 and industry best practices ✓ First step toward digital engineering (BIM) ✓ No constraint on using a specific software ✓ Common title block formats for all disciplines including tagging and file ✓ naming conventions and other metadata requirements (pictured) zyxwvutsrqponmlkjihgfedcbaZYXWVUTSRQPONMLKJIHGFEDCBA Asset Standards Authority Applied human factors: Hazard analysis | 9

CHAIR – Application currently has limitations Construction Hazard Assessment Implication Review = CHAIR CHAIR 1 - is performed at the conceptual stage of a design, which is the best opportunity to make fundamental change, even though much of the design is still to be determined. CHAIR 2 - focuses on construction and demolition issues and is performed just prior to construction, when the full detailed design is known. CHAIR 3 - focuses on maintenance and repair issues and is performed at the same time as the CHAIR 2 study. Developed in the late 1990’s CHAIR is construction focused. CHAIR 3 studies do consider some issues regarding maintainability of the asset but zyxwvutsrqponmlkjihgfedcbaZYXWVUTSRQPONMLKJIHGFEDCBA not operability. Note: CHAIR is no longer supported on the NSW Work Cover website. Asset Standards Authority Applied human factors: Hazard analysis | 13

Safety In Design (SiD) Focuses on safety interventions early in design. This is the most cost effective opportunity to do this. SiD involves the use of: • Hazard identification registers (HAZID) • Risk registers • Risk is eliminated or controlled so far as is reasonably practical (SFAIRP) levels • Any residual risk is identified and managed by the client • SiD workshops that involve stakeholder representatives especially the client zyxwvutsrqponmlkjihgfedcbaZYXWVUTSRQPONMLKJIHGFEDCBA • Stakeholder consultation should include actual end-users!

SiD in practice - example zyxwvutsrqponmlkjihgfedcbaZYXWVUTSRQPONMLKJIHGFEDCBA Exterior flood light at the top of a Light fixture rotates inwards to three story building facilitate safe access for maintenance Asset Standards Authority Applied human factors: Hazard analysis | 15

Lessons learnt – Human factors integration and safety in design • For projects at the simpler end, broadening the Safety in Design (SiD) process can be sufficient for Human Factors Integration (HFI) – SiD (under the WHS Act 2011) requires consideration of the safety of people during:  Construction  Maintenance  Operations  Disposal – Broadening the process to include:  Operability  Maintainability (the ease with which the asset can be operated and maintained) Note: CHAIR is often provided as evidence of SiD.

The ASA’s objective The Asset Standards Authority’s objective: • Is to develop standards to enable AEO’s to deliver: – Assets are both operable and maintainable – Are safe to operate and maintain – Deliver required performance • Human factors and human interaction is significant in these activities zyxwvutsrqponmlkjihgfedcbaZYXWVUTSRQPONMLKJIHGFEDCBA Asset Standards Authority Applied human factors: Hazard analysis | 18

What are human factors? • It is the scientific discipline concerned with the understanding of the interactions among humans and other elements of a system and the profession, that applies: – theory – principles – data – methods to design in order to optimise human well- being and system performance. zyxwvutsrqponmlkjihgfedcbaZYXWVUTSRQPONMLKJIHGFEDCBA Asset Standards Authority Applied human factors: Hazard analysis | 19

Human factors Overall system performance improves when human capabilities and limitations have been addressed in the design zyxwvutsrqponmlkjihgfedcbaZYXWVUTSRQPONMLKJIHGFEDCBA Asset Standards Authority Applied human factors: Hazard analysis | 20

Human factors at the ASA is… “Human Factors is about ensuring the delivered asset is both operable and maintainable, safe to operate and maintain as well as deliver required levels of performance” Key points: • It’s about the delivered asset or service (lifecycle) • It starts with good design (at least HF considerations in design) • It’s not only about safety, it’s about delivering to required design expectations – getting value • To achieve a good asset HF should be incorporated at concept and design zyxwvutsrqponmlkjihgfedcbaZYXWVUTSRQPONMLKJIHGFEDCBA Asset Standards Authority Applied human factors: Hazard analysis | 21

Human factors in the asset lifecycle Good asset performance begins at design Good design Leads to good asset zyxwvutsrqponmlkjihgfedcbaZYXWVUTSRQPONMLKJIHGFEDCBA performance Asset Standards Authority Applied human factors: Hazard analysis | 22

Human factors in delivered assets Making operable : • The finished asset works well for end-users • The needs of the end-user been properly assessed during the concept and design stages Making it maintainable: • The finished asset enables maintainers to keep it working well • Access for maintenance been zyxwvutsrqponmlkjihgfedcbaZYXWVUTSRQPONMLKJIHGFEDCBA considered Asset Standards Authority Applied human factors: Hazard analysis | 23 23

Hazard analysis – general principles zyxwvutsrqponmlkjihgfedcbaZYXWVUTSRQPONMLKJIHGFEDCBA Asset Standards Authority Applied human factors: Hazard analysis | 24

Hazard analysis – definitions Hazard – AS 61508 ‘Potential source of Harm’ Hazard ‘A potential source of harm. A condition that could lead to an accident. A hazard should be referred to a system or product’. zyxwvutsrqponmlkjihgfedcbaZYXWVUTSRQPONMLKJIHGFEDCBA Asset Standards Authority Applied human factors: Hazard analysis | 25

Why perform hazard analysis • As an afterthought when we • To stop people getting killed have done the design or injured • Because it says so in the • To enable the development contract of a SFAIRP design • To keep people happy! • To enhance the performance level of the final product • To tick the box • To provide assurance in the overall quality of the design zyxwvutsrqponmlkjihgfedcbaZYXWVUTSRQPONMLKJIHGFEDCBA • To demonstrate compliance with legislation Asset Standards Authority Applied human factors: Hazard analysis | 26
