BPI BA StandardsRespirators with filter cartridges must be worn when there is a danger of
exposure to what 5 substances? - correct answer ✔mold, asbestos, lead,
fiberglass, or formaldehyde
Maximum permissible level of CO in ambient air. - correct answer ✔35 ppm
3 recommended scope items that mandate pre- and post- blower door tests. -
correct answer ✔1. air sealing
2. enclosed cavity insulation representing 15% or more of the total building
shell area.
3. sealing of the ducts outside the thermal envelope.
Blower door results must be compared to _______ to determine if mechanical
ventilation is required. - correct answer ✔The Building Airflow Standard--
ASHRAE 62-89.
When are pre- and post safety inspections of all combustion appliances
required? - correct answer ✔Whenever changes to the building envelope or
heating system are recommended.

, When air sealing or other shell tightening measures are recommended, what
must be given highest priority? - correct answer ✔leakage paths to the attic
What are the 3 steps for calculating the minimum Building Airflow Standard
(BAS)? - correct answer ✔1. Calculate the ventilation required for the
building:
(.35 x volume) / 60
2. Calculate the ventilation required for the people:
15 cfm x # of people
3. Using the higher airflow requirement, covert to CFM-50 using the LBL "N"
factor (WI = zone 2) and the height correction factor.
When must mechanical ventilation be recommended? - correct answer

correct answer ✔+/- 10%
What are the 4 components of a heat loss and savings calculation? - correct
answer ✔1. R-values of installed insulation shall be determined based on
acutal measurement of the insulation depth and R-value per inch for that
product.
2. Voids in insulation must be accounted for.
3. Gaps between batt insulation and framing must be accounted for using the
Effective R-value for Batt Insulation Chart.
