Which of the following NISPOM chapters may NOT apply to all facilities?

Chapter 7, which pertains to subcontracting, may not apply to all facilities because not every facility engages in subcontracting activities. Some facilities may operate independently and not have subcontractors involved in their processes. This chapter specifically outlines the responsibilities of prime contractors regarding the management and oversight of subcontractors who handle classified information, which means if a facility does not partake in subcontracting, these guidelines do not apply to them.

In contrast, the other chapters address fundamental security principles that are typically relevant to all cleared facilities. Chapter 6 focuses on visits and meetings involving classified information, which is universally significant as all facilities handling classified data need to manage how such information is shared and discussed with visitors. Similarly, Chapter 5 emphasizes safeguarding classified information, a core requirement for any facility that has access to classified materials, thereby making it applicable universally across all such facilities.
