What extinguishing tactic is required for fires involving Class 5.2 Organic Peroxides (e.g. Dibenzoyl Peroxide UN 3102) under JT/T 617.6?

1. Apply massive quantities of water spray/deluge from a safe distance or behind uncrewed monitors to provide continuous flooding and cooling
2. Smother with dry foam blankets and avoid any water cooling
3. Blow hot air across the packages to dry them quickly
4. Seal the container tightly to trap the internal pressure
