Q

Q1: What is the difference between offensive, defensive, and nonintervention action options and objectives?

A

Offensive options include actions such as plugging a leak to control the incident, while Defensive options protect the surrounding area. The nonintervention option allows the incident to run its course, such as in the case of a BLEVE.
