What is the primary requirement for the Declaration of Inspection (DOI)?

The Declaration of Inspection (DOI) serves as a crucial document in marine safety, particularly in the context of transferring oil or hazardous materials. The primary requirement for the DOI is that it must be signed by all persons in charge before the transfer takes place. This requirement ensures that all responsible individuals are aware of the operation's safety protocols and emergency procedures. By having all key personnel sign the document, it promotes accountability and communication among those involved in the transfer process. This is essential for minimizing the risk of spills or accidents.

The intent behind this requirement is to ensure a comprehensive review of safety measures and procedures, fostering a culture of safety that permeates through the ranks of personnel involved in the dangerous task of transferring potentially harmful substances. By mandating that all persons in charge acknowledge the DOI, it reinforces the importance of shared responsibility in maintaining safety during these operations.
