What distinguishes an Extended Initial Safety Sweep (EISS) from a BISS?

The Extended Initial Safety Sweep (EISS) is designed to conduct a thorough and comprehensive assessment of the vessel's safety and operational condition. What distinguishes it from a Basic Initial Safety Sweep (BISS) is its broader scope in identifying potential hazards. The EISS places a greater emphasis on specific hazards that may not have been adequately covered in a BISS. It allows trained personnel to assess various areas of concern in detail, ensuring that all critical safety aspects are addressed.

While other options may touch on elements present in either an EISS or a BISS, the core feature of the EISS's focus on specific hazards fundamentally sets it apart. The inclusion of crew interviews and the additional duration are components that may enhance the sweep but are not defining characteristics that differentiate the EISS from the BISS in terms of hazard recognition and assessment. Similarly, while covering areas not previously inspected can occur during an EISS, it is not the primary distinguishing factor, as the focus remains on the thorough identification of specific dangers.
