My experience is actually just the opposite. My experience is that everyone who came to my office to make a report had an important idea to share or an important here-to-fore unreported risk to which to bring our attention.
By listening to the person reporting and taking time to clarify their concern, our safety programs achieved two important goals. First, we found risks that only one person recognized. Funny how in an organization of 300 people, that only one person will see and be willing to report a very valid hazardous risk. Not sure why that is so, but it is. Second, by listening to all who came in to report, and publishing all reports and recognizing the best each week, we developed the excellent reputation of being the “good listener.” You would be amazed at the things that really need to be fixed that no one else noticed or bothered to tell anyone about.
So, my suggestion is do not worry about “triviality.” In fact the report may be of quite some significance when you later understand its true potential for prevention.
Again that is my experience and I would add, that by doing so, our safety program achieved the goal of reducing losses due to injuries and deaths, property damaged or destroyed to zero. So, I would say that this program worked very well in four very different organizations.
