How long must the Dangerous Cargo Manifest (DCM) be retained for?

The correct duration for retaining the Dangerous Cargo Manifest (DCM) is one year. This retention period is established to ensure that there is an accessible record of dangerous goods on board a vessel for safety and regulatory compliance. Keeping the DCM for one year allows for a sufficient timeframe for investigations, audits, or inspections that may occur after the vessel has completed its voyage. Such records are crucial for the safety of port operations and environmental protection, as they provide necessary information to emergency responders and port authorities regarding hazardous materials that may be present.

The one-year retention period aligns with various maritime regulations, ensuring that records of dangerous cargo are maintained for a practical duration without overburdening operators. This timeframe strikes a balance between accountability and operational efficiency while still upholding safety protocols.
