Tankerman · Chemical — Compatibility
Before loading a chemical cargo, the tankerman must check a compatibility chart to ensure the cargo is compatible with:
- AThe previous cargo/tank coating, adjacent cargoes, and construction materials (gaskets, valves)✓ Correct
- BOnly the weather forecast
- CThe crew's preferences
- DThe vessel's paint color
Explanation
Chemicals can react dangerously with incompatible prior cargoes, tank coatings, gasket/seal materials, or neighboring cargoes (heat, gas, polymerization). The 46 CFR 150 compatibility chart and the cargo data sheets are consulted to confirm safe stowage and segregation before loading.
Authority: USCG Compatibility Chart (46 CFR 150); IBC Code
