London Branch Early Career Professionals Presentation Event
Join us to hear from three early career Safety & Reliability professionals as they present on interesting safety and reliability projects from a variety of industries. Each 15 minute presentation will be followed by questions asked by the audience via the webinar chat system. After all three presentations and Q&A sessions, the audience will be invited to vote on which was the best presentation overall and the prize will then be awarded to the winner.

The three entries selected for presentation are:
Sophie Brown – Risk Consultant, Arup:
In Sophie’s presentation, we will learn about the Hy4Heat programme, the aim of which is to establish if it is technically possible, safe and convenient to replace natural gas with hydrogen in residential and light commercial buildings. As part of this programme, a comparative safety assessment that was focussed on risk within domestic properties was undertaken. This took into consideration a variety of factors and used quantitative risk assessment as well as a range of experimental tests to verify that the risks of conveying hydrogen are no greater than the accepted risk level associated with the current use of natural gas.
The assessment was independently reviewed by the Health and Safety Executive, culminating in a letter of assistance from that organisation.
Nic Bowler – HM Specialist Inspector of Railways (HF), Office of Rail and Road (ORR):
On 7th May 2020, a freight train passed two red signals. The second was protecting the junction ahead for the passage of a high-speed passenger train. Fortunately, the design of the signalling system, timing of both trains and the passenger train driver’s ability to identify the signal reversion, enabled the passenger train to stop in advance of the potential collision point.
In line with its Mandatory Investigation Process, ORR conducted an independent investigation to ascertain the causal and contributing factors of the incident and identify if there had been any breaches of the law. This involved gathering information from a wide variety of sources. In Nic’s presentation, we will hear about the investigation from the interesting perspective of someone within the regulatory body for the railways.
Hamzah Hussain – Junior Safety Engineer, AFRY:
Fault Tree Analysis (FTA) is a powerful technique that can be used to model a systems behaviour by decomposing it in a hierarchical manner, starting with an end effect and working backwards to identify causes. The analysis can be stopped at any level depending on the objectives. FTA allows the modelling of common mode failures that have the potential to undermine the integrity of the system.
Although FTA usually produces a numerical evaluation of the top event, more important that this is the failure logic that leads to the top event, i.e. the combination of events that have to occur to realise the top event.
Hamzah’s presentation will look at how FTA was applied in a Reliability assessment of an electrical distribution system for a high hazard facility, and will discuss the benefits of applying the technique despite imperfect data.
