This work outlines the experimental conditions and tests results for a cylindrical carrier submitted to a large (>20 m2) and powerful (>40 MW) pool fire to assess its compliance with safety regulations for transporting hazardous materials. Data from thermocouples placed around the carrier, above the pool fire, in the fire plume, and from plate thermocouples at the edge of the pool fire are provided. The temperature criteria of 800 °C were met both close (10 cm) and away (50 cm) from the tank. Furthermore, a validation analysis was performed using Fire Dynamics Simulator code to assess its predictive capabilities for simulating large-scale pool fires with engulfed tanks. Numerical results demonstrated good agreement with the experimental data, highlighting its potential to assist in the dimensioning or design of such large-scale tests. •Detail of experimental conditions and results for a carrier submitted to a large (>20 m²) and powerful (>40 MW) pool fire.•Dedicated to tanks or objects transporting dangerous goods, namely a full engulfment into a pool fire and at least 800°C.•Can be used to help dimensioning or designing such large scale test, for pre-test or package sizing.•This work can also be used as a reference for large pool fires with numerous experimental data.•Validation case of CFD tools for large-scale application with details on fuel, geometry, and consequent instrumentation.
