Document type: Process / Standard Operating Procedure (SOP)
Vertical: LFP (Lithium Iron Phosphate) battery energy storage systems (BESS)
Scope: One cross-border transit leg, People’s Republic of China → Czechia (EU)
Document owner: Tradvolt Operations, HSE desk
Last reviewed: 2026-09-21
Define a reproducible drill sequence that the escort driver, customs broker, and Tradvolt HSE duty officer execute when a vertical LFP cabinet registers a thermal runaway event during the CN→CZ road transit leg. The procedure is calibrated for LFP chemistry and is exercised at least once per quarter per corridor.

| 2 | Pull BMS telemetry from the cabinet and confirm: cell temperature > trigger threshold, pack voltage drop, smoke sensor trip. | Driver + OEM monitor (per OEM service manual) | OEM BMS LIVE FEED | INCIDENT-T0-REPORT | All three signals have a timestamp and a unique cabinet serial on the log. |
| 3 | Vehicle stops at the next safe pull-off; ignition off; parking brake; wheel chocks fitted (per ADR cab-side checks). | Driver | INCIDENT-T0-REPORT | INCIDENT-T1-REPORT | GPS pin recorded and 50 m isolation perimeter visually verified by the escort. |

| 10 | Replace vehicle, recover the shipment, or reroute to a bonded warehouse — decision recorded by Tradvolt Operations and signed by the client. | Tradvolt operations lead | CHAIN-OF-CUSTODY | DECISION-RECORD | One of three outcomes is logged: safe to continue / replace / reroute. |
| 11 | Post-drill debrief (max 4 hours after the live event); corrective actions raised in Tradvolt CAPA queue. | HSE duty officer | DECISION-RECORD | DEBRIEF-NOTES | Each correction has an owner, due date and an ISO 2859-1 AQL reference where applicable. |
| 12 | Update the corridor runbook and notify the OEM service desk if the BMS firmware revision quoted a thermal runaway signature. | Tradvolt operations lead | DEBRIEF-NOTES | RUNBOOK-REVISION | New revision number and effective date posted to the corridor file. |
