Gasoline Tanker Roll-over DOT Guide 128  Isolate 80 to 160 feet in all directions  Evacuate 1,000 feet for a large spill  Evacuate ½ mile for fire

Objectives  Rescue/EMS (Medic, E2)  Identify product (Dispatch, E2)  Isolate (E2, APD, T6)  Identify exposures (E2) and contain run-off (E6, Street & Highway Dept.)  Establish water (E5) & foam (E12, BT12) supply and provide protection lines & master stream capability (E5, E2)  Stabilized truck (Kelly-McKnight), stop leak (HM6)  Transfer product & clean-up (HM6, Eagle)

Negatives 1. Communications A. Crews put on lines for an operation that was then canceled - crews not told B. Changed game plan, but didn’t inform Rehab C. T6 didn’t understand what HazMat wanted to do D. T6 told dispatch to notify State- he wanted Highway Dept., got DPS. Be specific. 2. Contractors (and Chiefs) not in protective clothing in the Hot Zone

Negatives 3. Dome clamps didn’t work - they are applied to prevent the dome from failing as a standard precaution. They are not designed to stop leaks, but to reduce the severity. Only one dome was leaking at the beginning, all were at the end. 4. Foam nozzles not used - doubles the amount of foam needed, lack of air- entrainment and increased ¼ drain time.

Negatives 5. Class A foam is not AFFF!!! 6. Late getting clean-up contractor on-scene (Trucking Co. in denial) 7. Transfer of the incident to contractor - follow-up with the company (B-2)

Improvements 1. Communicate plan to all - stop operation and call a meeting if necessary. 2. Establish a formal ICS - most positions were assumed, not specifically delegated/appointed. 3. Understand the tactics, techniques and capabilities of the HazMat Team. 4. Communicate with the clean-up contractor early, and follow-up with them. Have HazMat relate special equipment needs to them.

Positives 1. Called for help early- TxDOT, TNRCC, Rothwell, Kelly-McKnight, Trucking Co., Pro- Tech, HazMat, APD, Pollution Control Officer from City of Grand Prairie. 2. No run-off to storm sewers, identified locations early, blocked for worst-case loss. 3. Water supply established (E-5), protection line in place for HM. 4. Driver self-extricated, and EMS on-scene quickly. 5. IC planned for worst-case scenario.

Positives 6. Foam available 7. Identified product, got shipping papers. 8. Rotated crews, set-up Rehab early, had lots of help. 9. PIO on-scene. 10. Met with all parties to establish plan prior to clean-up initiation (not response, clean-up) 11. PORTA-POTTIES!

Why we didn’t Foam 1. Stability of the tanker, wash-out of the supports. 2. Ground absorbed all liquid, small surface area,  200 gallons. 3. Creates slipping hazard for members in the foamed area. 4. Waited for sand to contain run-off.
