🛡️ Set the Perimeter

A fixed accidental-explosion civil-protection scenario — a fuel storage tank, an industrial site. Your job: set the safety perimeter radius to exactly match the required standoff distance. Too small and the threshold is exceeded inside the perimeter; too large and you've fenced off more land than needed.

🔒 Scope: Civil-protection / accidental-explosion planning only. No weapon-effects or penetration content — this game is about setting safe distances, not analyzing attacks.

Scenario

Accidental charge: 250 kg TNT-equivalent

Damage threshold: 7 kPa (minor structural damage)

Your Perimeter

Radius R 50 m

Correct Radius

This game runs the exact same overpressure formula (engine/blast.js → peakOverpressureKG) verified elsewhere on this platform. The correct answer (250 kg, 7 kPa threshold → R≈83.7 m) was independently computed and cross-checked before publishing.
