The interviewer wants to ensure that they could rely on you to be an asset in this regard rather than a liability and that you would uphold their safety practices and standards. Familiarize yourself with their safety standards and best practices. "We are committed to achieving the highest possible safety and security standards for our customers, their passengers, our employees and our facilities. At several of our locations, we've been the first provider to achieve the IATA Safety Audit Programme for Ground Operations (ISAGO) accreditation. Our safety initiatives, training and approach to people are industry-leading. Combine all these and we're well on track to achieving our safety vision of having a culture where all of our people possess the skills, knowledge and confidence to work safely, feel respected and are engaged in helping everyone stay safe." Mention any health and safety-related training you have taken, and bring any current certificates and tickets to the interview.
