-Evacuate area immediately, stop traffic, clear area of responders and publice for at least 1 mile in all directions, let it burn
Explosives:
Response objectives w/ no fire
Isolate area and establish perimeter of 1/3 mile in all directions, request assistance from bomb squad, do not touch, move, or disturb material until bomb squad is consulted, consider initial evacuation of 1/2 mile in all directions for larger spill

Clandestine Drug Labs:
Situation 1: Assisting law enforcement at clandestine drug labs
- Hazmat squad officer is liason
- Stay out of unsecured scenes
Clandestine Drug Labs:
Situation 2: Response to fires involving known or suspected clandestine drug labs
- Defensive strategy unless there is a vialbe life-saving rescue
- If no viable life-saving rescue, isolate area, protect exposures, let it burn
Clandestine Drug Labs:
Situation 3: Encountering Clandestine Drug Labs Unexpectedly
- Don’t touch anything
- Advise AFD dispatch and request PD
Suspicious Letters and Packages:
Situation 1: Response to suspicious letter or package with unknown powder and an articulated (explicit) threat.
- Tell people not to touch shit.
- Hazmat Recon Team, consisting of 2 Hazmat Technicians, will begin hazard assessment and conduct a preliminarty reconnaissance of the area.
Same for Situation 2, powder w/ no articulated threat, Situation 3, articulated threat with no powder may not require recon team
