What differentiates an Extended Safety Sweep (ESS) from an Initial Safety Sweep (ISS)?

The Extended Safety Sweep (ESS) differs from the Initial Safety Sweep (ISS) primarily in its scope and focus. The ESS is intended to be more comprehensive, as it expands the search beyond initial safety concerns observed during the ISS, which is primarily a quick assessment to determine any immediate dangers.

While the ISS is designed to quickly identify and mitigate any urgent safety threats in specific areas, the ESS takes a more thorough approach, concentrating on particular zones where potential hazards might exist—this allows personnel to conduct a detailed examination of those areas to ensure the safety of all individuals on board. This focused search aims to identify risks that may not have been immediately apparent during the initial sweep, such as improperly stowed gear, explosive materials, or other safety hazards that could pose a risk during further interactions with the vessel.

The other choices do not accurately capture the essence of what defines an ESS compared to an ISS. For instance, while the ESS does involve a broader search than the ISS, it particularly emphasizes examining areas of potential hazards rather than simply covering all parts of the vessel indiscriminately. Additionally, while the ability to arrest subjects may be a part of the operational protocol during any boarding situation, the ESS itself does not inherently provide a power for immediate arrest; rather
