SOPs & IMS will be utilized, with a Unified Command involving other affected agencies. IC must notify Dispatch of the Command Post location as soon as it is established.
Role of a Chief Officer in the Papago Tunnel response.
First Chief should respond to the incident site with the flow of traffic, or as directed by the first due company and traffic coordinators. Consideration should be given to sending a Chief to the ADOT Traffic Ops Center to provide liaison for the IC.
Describe SOPs for responding to a major fire in the Papago Tunnel.”
Confirming the exact location of the incident, routing crews from the opposite direction into the tunnel, stopping traffic for emergency vehicle access, checking the tunnel for victims, positioning apparatus uphill from the drain system, ensuring adequate foam capacity, and addressing haz mat contamination.
Actions should be taken to address a haz mat problem in the Papago Tunnel?”
Watching for moving traffic, increasing tunnel lighting, adjusting exhaust fans’ direction and volume, and considering air contamination.
How should emergency personnel access the incident site in the event of a major fire in the Papago Tunnel?
Route crews from the opposite direction into the tunnel, against traffic when safe to do so, and have DPS stop traffic for emergency vehicle access.

Because of possible restricted access around the sides of a major incident, 2 or more may be required.
Measures to take to protect victims and rescuers during a major fire in the Papago Tunnel?
First attack lines should protect victims and rescuers, and second attack lines should address fire control and extinguishment. Additionally, stang guns may prove effective for reach and knockdown due to extensive debris and limited access to the seat of the fire.
