Methodology for Comparing Dangerous Goods Risk in Road Tunnels to Those on Alternative Routes

This webinar presents the work involved in developing a standardised comparative risk assessment method for assessing life safety risk of dangerous goods being routed through the tunnel or via an alternative surface route. The project was conceived to focus on new road tunnel projects, but the methodology developed could also be used for comparative assessment of alternative surface routes.

Dangerous goods are a wide variety of substances and objects that pose acute risks to people, property, and the environment due to their chemical or physical characteristics. The transport by road of such goods is necessary to achieve broad societal benefits, yet such transport has inherent risk of significant events adversely affecting people (road users, adjacent populations, and responders) and the environment.

The webinar describes the proposed methodology as well as providing a case study application of the methodology to aid practitioners. The session provides a summary of the legal context for undertaking such assessments and the responsibilities that lie with the various stakeholder parties. The authors also present the broader context in which the life safety assessment results should be considered and the other decision-making factors that should be applied.

The webinar is presented by Dr Conrad Stacey and Nigel Casey.
