Reply #1: Big Oil operates refineries like they operate everything else...

[skeptical cynic]

in run-to-fail mode. Consider the BP refinery fire resulting from a lack of process safety management, and their current legal troubles stemming from a failure to take the lessons of the first explosion and loss of life seriously. Or consider the oil spills on Alaska's north slope, caused by a failure to meet even the minimum requirements for corrosion control.

Big Oil will only protect human health and the environment when killing their employees and polluting the soil, water and air comes with a higher price-tag.

Expect a heartfelt public statement from a very sincere-sounding executive who probably just received a very big annual performance bonus for cutting costs.
