Tell me about a time you made a mistake that could have compromised safety. How did you handle it?

At the end of a long shift at my previous job, I was securing equipment in the yard and inadvertently left one machine's safety guard unfastened. I was halfway to the car park when I realised what I had done.

I needed to correct my mistake immediately and report it transparently, even though no one else had noticed and I was tired and eager to go home.

I turned around and went back to secure the guard properly. The next morning, I told my supervisor what had happened, even though it was embarrassing to admit. I suggested we add a final walk-around check to the end-of-shift checklist so that no one could leave without a second pair of eyes verifying the equipment.

My supervisor appreciated my honesty and implemented the double-check suggestion. The new step became part of the standard closing procedure, and there were no similar incidents in the following months. It taught me that owning up to mistakes quickly earns trust and leads to better systems for everyone.
