This concept seems kind of obvious but also very effective. I have worked for a couple of major companies and have seen it put to use. One of the companies was in the Petrochemical industry. Safety is a huge part of their culture. They applied the principle of "Safety First" to every aspect of the company. It didn't matter if you worked in the field or in an office they took safety very seriously. One of the ways they did this was by having a "safety moment" before every meeting. In my group we would rotate the duty of presenting a safety topic every week before our meetings. I'm a skeptic at heart and it was hard for me to embrace this idea but in the end I appreciated the fact that we spent time discussing topics ranging from driving safety to ergonomics and many other things. The idea is that we cared about our coworkers and wanted to see them go home safe be safe there and come back to work in the same condition. It sounds kinda cheesy but in the end it made a huge impact on me, so much so that I have brought the concept of safety moments to positions I have held at other companies.
