Passive mitigation is defined in § 68.3 as "equipment, devices, or technologies that function without human, mechanical, or other energy input." Passive mitigation systems include building enclosures, dikes, and containment walls. Measures such as fire sprinkler systems, water curtains, valves, scrubbers, or flares would not be considered passive mitigation because they require human, mechanical, or energy input to function.
What measures qualify as "passive mitigation"?
