During a road transport emergency involving a severe Liquid Chlorine (UN 1017) or Anhydrous Ammonia (UN 1005) vapor leak, what is the correct technique for deploying water fog (水幕 / 喷雾水)?

1. Deploy water fog curtains downwind to absorb and dilute the airborne toxic gas cloud, but NEVER spray solid water streams directly into the liquid pool inside the breached container
2. Direct high-pressure solid water streams straight into the liquid chlorine pool to make it boil faster
3. Drink the chemical runoff water to prove it is non-toxic to bystanders
4. Use water spray to blow the toxic cloud directly toward nearby residential apartment complexes
