It starts with the idea of the inherently safer design principle and that involves elimination. You can take out one hazard but are you increasing the presence of other hazards? What's better? What's worse? This is a judgment call that needs to be made on an engineering basis.

This episode reiterates that process safety requires constant vigilance. The challenge is when it works well, nothing goes wrong. People then question if you really need to spend all that money on safety efforts. The reason nothing is going wrong is because you’re doing it right.
