Which of the following are general elements that should be reviewed in a systematic plans review?

• A. Occupancy classification and means of egress
• B. Fire resistance ratings
• C. Material finishes
• D. HVAC system efficiency

Answer: (A)

The main idea is that a thorough plans review centers on life safety by understanding how the space will be used and how people will move to safety. The occupancy classification tells you what type of occupants will use the building and drives all safety requirements, while the means of egress shows how people can exit safely in an emergency. Together, they determine necessary exit access, number of exits, exit widths, travel distances, doors, stairs, emergency lighting, and signage. Getting these right sets the framework for the rest of the review and ensures that people can leave promptly and safely.

Fire resistance ratings are important, but they pertain to how the building’s structural and fire‑separating elements resist fire, a detail that follows once the life-safety framework is established. Material finishes affect flame spread and smoke development, but they are evaluated after confirming appropriate occupancy use and egress provisions. HVAC system efficiency is not a primary focus of a broad life-safety plan review; it relates more to energy performance and comfort, though certain mechanical design aspects related to fire safety (like duct separation) can come into play separately.
