Confined Space CO₂ Risk Update for Maritime Operations
Complete your details below to receive the whitepaper instantly
Confined space entry remains one of the highest-risk operations in maritime environments. Recent fatal incidents linked to carbon dioxide (CO₂) exposure have prompted updated guidance under IMO MSC.581(110), introducing stronger expectations for atmospheric testing in enclosed and adjacent shipboard spaces.
Why This Update Matters
The updated IMO guidance reflects growing concern around CO₂ accumulation in confined shipboard spaces such as cargo holds, ballast tanks, and pump rooms.
Traditional oxygen-only testing may not be sufficient to identify hazardous atmospheric conditions, particularly in spaces where CO₂ can accumulate without visible warning signs.
Confined Space Gas Detection Considerations
Multi-gas detection systems such as the MSA ALTAIR 5X Multigas Detector can support confined space entry procedures by enabling detection of oxygen, flammable gases, toxic gases, and optional CO₂ sensing depending on configuration.
Equipment selection should align with vessel type, cargo risk profile, and regulatory requirements.
