Sustainability Report 2021

Case Study: Exploration Safety IGO is one of the few exploration and mining companies in Australia that maintains a significant in-house geophysical team, with both technical specialists and field-based technicians. Traditionally, our field based geophysical team have used All Terrain Vehicles (ATVs), also known as quad bikes, to carry out most of our survey activities. During FY21, IGO had a number of high potential incidents involving ATVs, which thankfully did not result in any serious injuries, however, there was potential for more serious outcomes. IGO considers proactive safety management to be an essential part of injury prevention, so in October 2020 we suspended all ATV activities across our business. This included all geophysical surveys by our own teams, our contractors and other exploration activities using ATVs, such as soil sampling. IGO’s Exploration team undertook a comprehensive review of our ATV practices to achieve a step change improvement in our safety performance. This included: • a historical review of ATV incidents to understand common contributing factors • the completion of a detailed risk assessment, with subject matter experts • a knowledge sharing workshop with our industry peers that also use ATVs • an update of our ATV bow tie risk assessment and critical control checklist; and • an update of our internal procedures and engineering modifications to our vehicles and trailers. 1. Note: We have changed the way we calculate the TRIFR to align with our resources industry peers to include total reportable injuries and exclude those categorised as illnesses. These will now be reported in other data.
