SFFMA Firefighter I (FF1) HazMat Operations Awareness Practice Test

Redirecting the flow of a hazardous liquid away from people or sensitive areas is a control tactic that aims to keep the hazard out of reach by changing where the liquid travels. This is known as diversion. By creating barriers or using trenches and berms, responders steer the spill toward a safer area or into a designated containment path, reducing exposure and potential damage. Absorption would involve the liquid soaking into a material, which removes but does not redirect the source flow. Dispersion means the liquid spreads out, often increasing the area affected. Retention is about keeping the liquid in one spot, which may still pose risk without moving it away. So diversion is the best choice because it actively changes the flow direction to protect people and property.
