OK, this may be a reach, but this video of a shark turning into a snack for a grouper is a reminder of a fundamental flaw in a lot of our hazard analysis.
One of the mistakes we make in managing hazards is to confuse protection with prevention. Protection means workers are at risk and we take steps to keep them safe. Prevention means we remove the risk completely and workers are not at risk. The biggest difference is that when we protect, we can never forget that the risk didn’t go away.
But we make that mistake all the time. We do our bow-tie analysis, we create a barrier for all of the hazards and we convince ourselves (at least on a subconscious level) that we have prevented a catastrophic event. However, we haven’t. We hope we have protected workers, but the hazard never went away.
This is a pretty amazing video, if nothing else because it reminds us that, no matter how big your teeth are or how thick your armor, you are just bait for some other fish when things go wrong. The moral is: Big and mighty hazard controls protect, but they don’t prevent incidents. They can actually become their own weakness if they lull us into a false sense of security.
