Operational waste, cargo residues and deck containment

RISQ 5.3Section 5 · Pollution Prevention and ControlSource marking: V

Applicability: Apply the vessel, equipment and operational conditions stated in this entry.

What is being checked

Personnel understand Annex V waste controls and maintain deck containment.

Ready on board

0 / 6 checked

Check the vessel’s actual procedures, equipment and records against these points from RISQ 3.2.

Have personnel distinguish operational waste from cargo residues using the source definitions and explain the applicable disposal arrangements.Include solid waste/slurries from maintenance, ship operation, stowage and handling, plus hold/external-wash-water cleaning agents and additives, in the operational-waste assessment.Distinguish grey water, bilge water and similar essential discharges, which the source excludes from its operational-waste definition.Identify wet/dry residues, loading/unloading spillages and residues in wash water; the source excludes deck dust remaining after sweeping and dust on external ship surfaces from the cargo-residue definition.Plug deck scuppers during operations with residues harmful to the marine environment (HME).Have manager procedures maintaining containment integrity, including drain valves where fitted and controlled drainage of accumulated deck water.

Practice questions

Preparation prompts derived from this entry, not an official inspector interview script.

1Does the definition include cleaning additives in hold wash water?

Yes. The source includes these in operational waste; their presence must be considered in the disposal arrangements.

2What deck control is specified for HME residue operations?

Plug scuppers and maintain containment, with procedures for drain valves and controlled drainage.

Where a finding may arise

Missing evidence, defects or operation inconsistent with the arrangements described above may prevent a satisfactory answer. These are preparation concerns derived from the question, not 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

This paragraph defines waste streams and containment controls; it is not a complete discharge-permission table. See 5.18 for the explicit HME-residue shore-disposal requirement.
