What is the responsibility of the first due engine in a post-blast scenario?

In a post-blast scenario, the responsibility of the first due engine includes a cautious approach to the scene, specifically maintaining a distance of 500 feet. This is crucial for ensuring the safety of the personnel responding to the incident and to assess any potential hazards that might still be present, such as secondary explosions, structural instability, or the presence of hazardous materials.

By staying at a safe distance, responders can evaluate the situation without putting themselves at unnecessary risk. This precautionary measure allows for a thorough understanding of the scene before committing to any further action, which is essential in emergency response situations where conditions can rapidly change.
