When a transport vehicle carrying Class 1 Explosives is involved in an incident where a fire has spread directly to the explosive cargo, what is the critical emergency tactical rule under JT/T 617.6 and public security protocols?

1. Do NOT attempt aggressive close-range manual firefighting; immediately establish a cordon of at least 800 to 1,000 meters, sound evacuation alarms, and retreat to safe blast shelter immediately
2. Have the driver climb on top of the burning dynamite with a handheld 1-liter extinguisher to smother the flames
3. Pour small cups of engine oil onto the explosives to lubricate the chemical bonds
4. Lock all cargo doors and stand 5 meters away to film the explosion for social media
