Which statement describes how AMDQ is determined?

• A. It uses fixed values for all spaces
• B. It is adjusted by design factors
• C. It is the same as AMDQ for all systems
• D. It is based on weather conditions

Answer: (B)

AMDQ is not a fixed number; it is determined by applying design factors that reflect how a specific space will behave with the agent. These design factors include room volume, leakage through openings, anticipated distribution and mixing, target concentration, occupancy, and other conditions that influence how quickly and effectively the agent reaches the required concentration. Because these factors vary from space to space, the AMDQ must be adjusted accordingly to meet the design goals. Weather conditions are not part of the AMDQ calculation, so the correct statement emphasizes that AMDQ is determined by design factors.
