Calcium-hypochlorite hazard awareness
Applicability: Section 8D applies only to cellular container ships. It must not be used for non-cellular ships carrying containers. Calcium hypochlorite or mixtures in containers.
What is being checked
Officers understand heat-release hazards and cargo-specific stowage.
Ready on board
0 / 3 checkedCheck the vessel’s actual procedures, equipment and records against these points from RISQ 3.2.
Practice questions
Preparation prompts derived from this entry, not an official inspector interview script.
1Is calcium chloride the same substance as calcium hypochlorite?
No. The source’s water/calcium-chloride example illustrates an exothermic reaction involving a different substance; it is not a calcium-hypochlorite handling instruction.
Where a finding may arise
Missing evidence, unsafe arrangements or gaps in familiarity against these checks may prevent a satisfactory answer. These are derived preparation concerns, not additional explicit finding criteria or reported past observations.
Past observations for practice
Anonymised reports, manually reviewed before publication. These are reported experiences, not additional inspection requirements.
No reviewed observations have been added for this entry.
Share an observation for private review
Remove vessel, company and inspector names, report numbers, exact dates and confidential information. Do not paste a complete inspection report.
Source clarification
The extract does not provide a complete chemical-response procedure. Do not infer extinguishing or water-application instructions from its general chemistry example.
