Hazardous Materials 6th Edition Practice Test

Defensive mode is about protecting people by keeping a safe distance from the hazard and avoiding direct contact with the material. The goal is to limit exposure and prevent the release from causing more harm, not to attack or manipulate the substance directly. In practice, responders set up perimeters, use remote containment and barriers, apply engineering controls like shutoffs or dikes from a safe distance, and deploy appropriate protective equipment while prioritizing evacuation and decontamination. This approach buys time, reduces risk to responders and the public, and preserves life and property by keeping the hazard at arm’s length rather than engaging it directly.
