CETA Calculations Graded A+

1. Calculate Air Changes Per Hour (ACPH)

To calculate air changes per hour, you first need to determine the room's volume and the total airflow
from HEPA filters.



- Room Volume:

- \( \text{Room Volume (cubic feet)} = \text{Length} \times \text{Width} \times \text{Height} \)



- Total CFM from HEPA filters: Measure the airflow in cubic feet per minute (CFM) from all HEPA filters
in the room.



- ACPH Calculation:

- \( \text{ACPH} = \left( \frac{\text{Total CFM}}{\text{Room Volume}} \right) \times 60 \)



---



2. Calculate Air Changes Per Hour from Primary Engineering Control (PEC)

For PEC, the process is slightly different:



- Calculate CFM for PEC:

- \( \text{CFM} = \text{Length} \times \text{Width} \times \text{FPM} \)



- ACPH Calculation:

- \( \text{ACPH} = \left( \frac{\text{Total CFM}}{\text{Room Volume}} \right) \times 60 \)



---

, 3. Determine Minimum CFM Required from Ceiling HEPA Filters in Hazardous Drug (HD) Room

This calculation ensures you meet minimum air change requirements.



- Minimum ACPH Requirement: Start with the required ACPH for that ISO Class (e.g., minimum 30
ACPH).



- CFM Calculation:

- Convert ACPH to CFM:

\[ \text{Minimum CFM} = \frac{\text{ACPH}}{60} \times \text{Room Volume} \]



Example:

If the room volume is 500 cu. ft.

\[ \text{Minimum CFM} = \frac{30}{60} \times 500 = 250 \text{ CFM} \]



---



4. Calculate the Quality of Particle Counts in a Room

To assess the number of sample locations based on particle counts:



- Calculate Room Area:

- Total area in inches:

\[ \text{Area (in²)} = \text{Length} \times \text{Width} \]



- Convert to square feet:

- \[ \text{Area (ft²)} = \frac{\text{Area (in²)}}{144} \]



- Convert to meters:

- \( \text{Area (m²)} = \text{Area (ft²)} \times 0.093 \)
