Many these days will decry the concept/practice of “Cardinal Rules” as if they are a bad thing and then suggest that workers go out and identify “Stuff That Kills you” (STKY) which is at the very heart of the Cardinal rules administrative control approach. The belief is that once the serious hazard is identified that a group of workers who perform these high-risk tasks will have the knowledge and skills of how to best mitigate the risks this hazard poses.
