  - (2) **A description of the dangers of asphyxiation from the inerting gases used on the vessel.**
  - (3) **The measures that mitigate embrittlement of steel structure in way of cargo leakage.**
  - (4) **The use of the firefighting systems on the vessel.**
  - (5) The features of the cargo containment system that affect its operation and maintenance, including pressure and temperature ranges and relief valve settings.
  - (6) **Pressures, temperatures, and liquid levels for all operations.**
  - (7) **General information derived from the first loading of the vessel.**
  - (8) **Alarm settings.**
  - (9) **Descriptions of the components of the cargo system, including the following—**
    - (i) **Liquid cargo system.**
    - (ii) **Liquid recirculating or condensate return system.**
