Coal monitoring instruments and response records
Applicability: Coal carriage. Apply the actual coal schedule, ship arrangements and cargo-specific monitoring/response procedures.
What is being checked
Coal monitoring detects and prompts action on gas and heating risks.
Ready on board
0 / 7 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.
1Does a sounding-pipe temperature represent the whole cargo?
No. The source warns it only detects heating near the pipe.
2Should ventilation always be stopped on high CO without considering methane?
No. The source also prioritises explosion risk from rising methane. Use the cargo procedure and expert advice for the combined condition.
Where a finding may arise
The RISQ paragraph identifies incomplete monitoring records and failure to act where CH4 reaches/exceeds 20% LEL or CO exceeds 50 ppm as finding concerns. Maintain both complete records and evidence of the response; the thresholds are not safe-entry limits.
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.

Source clarification
Source cautions: CO is an indicator of self-heating, not its cause, despite the PDF’s causal phrasing. The PDF quotes roughly four hours without ventilation before gas measurement and closure for CO above 50 ppm or a three-day rising trend, but also prioritises methane ventilation at rising levels above 20% LEL. These excerpts are not a stand-alone ventilation sequence; use the approved cargo procedure and expert advice, considering both hazards. The source’s probe-depth comment is equipment-dependent.
