The building's ____________ will contain instructions for how to respond in the event of an emergency?

The appropriate term that refers to the set of instructions detailing how to react in an emergency situation is the "Occupant Emergency Plan" (OEP). This plan is specifically designed to address emergency response procedures for building occupants, covering various scenarios such as fire, natural disasters, or hazardous materials incidents. The OEP typically outlines evacuation routes, emergency contacts, and responsibilities among staff, ensuring that individuals know exactly what actions to take to ensure their safety and the safety of others during an emergency.

In contrast, while a security plan may include some information related to emergencies, its primary focus is typically on overall security measures rather than specific emergency response procedures. The term "3155" does not provide relevant context to emergency instructions, possibly referring to a document or code number that is specific to a certain protocol or standard but lacks immediate clarity in this context. Similarly, "safe plan" is vague and not a recognized term in the realm of emergency preparedness, which does not provide a structured approach or detailed guidance specific to emergencies. Thus, the Occupant Emergency Plan stands out as the correct answer for providing comprehensive and actionable information for emergency situations in a building.
