Describe the situation, the potential hazards, and the steps you took to ensure that all safety protocols were followed. Emphasize any coordination with team members or other stakeholders, and the outcome of your actions.

Example: “On a project assessing soil contamination at an old industrial site, I noticed some team members were getting a bit too comfortable and not fully adhering to the safety protocols we had in place, especially around wearing PPE and managing hazardous materials. Recognizing that complacency can lead to accidents, I decided to take action.

First, I conducted a quick refresher meeting on the importance of our safety protocols, emphasizing real-world examples of what could go wrong if protocols were ignored. Then, I implemented a buddy system where each person was responsible for checking their partner’s compliance with safety measures throughout the day. This peer accountability made a noticeable difference; everyone became more vigilant, and the project’s safety record remained flawless. It reinforced that safety is a shared responsibility and can be integrated seamlessly into daily routines without hindering productivity.”
