One characteristic of most major process safety incidents is that before they occurred, there were noticeable indications that a problem was developing. It is good practice for teams to discuss examples of weak signals that they have seen in their facility. Weak signals can be a vital opportunity to act early to avoid an accident, so it is important that they are persistently explored to understand the cause.

🔺 We persistently explore the causes of changing indicators or unusual situations.
