Tell me about a time you had to make a quick decision under pressure.

During a busy evening shift at my previous workplace, a piece of critical equipment began making an unusual grinding noise and vibrating heavily. It was not a complete failure, but it was clearly not operating normally, and we had a full workload to get through before the end of the night.

I needed to decide immediately whether to continue using the equipment, stop it, or find an alternative, all while ensuring safety was not compromised.

I stopped the equipment straight away and placed an out-of-service tag on it, following our isolation procedure. I recalled a similar scenario from our annual safety refresher training, which had emphasised that unusual noises should always be treated seriously. I reported the issue to my supervisor, switched to our backup process, and informed the team of the change in procedure so everyone could adjust their workflow.

The maintenance team discovered a worn bearing that could have caused a catastrophic failure if left running. My prompt action prevented potential injury and equipment damage, and the shift was completed using the backup method with only a minor delay. My supervisor used the incident as a positive example at the next all-hands meeting.
