will be immediately addressed by maintenance and the Fire Department. (Readings are noted on the
attached test data sheet)
f. CO2 levels in any occupied space are below threshold limits.
i. Perform CO2 check with Gray Wolf or other portable device. Measure four times yearly or more
often if needed. Measure only in fully occupied rooms. Reading should be less than 700 PPM plus
outside air CO2 PPM.
700 PPM + 383; 355; 373; 422 PPM = 1083; 1055; 1073; 1122 PPM

N/A
In North we have 1/2 of an Air Handling Unit (AHU) not operating correctly. This will be
repaired May 18 and 19. The air is moving but reduced by 1/2. We did increase Outside Air
settings to assist in improving air flow. On the fourth day a chiller was down causing the
temperatures to be higher. I will retest the high reading once the AHU is fully operational.
ii. If reading is above threshold, check univent and air handling dampers to ensure a value is set to
provide at least 15 cfm of fresh air intake per student based on average space occupancies. If
reading is consistently elevated, then use data logging to monitor CO2 concentrations over time and
look for other sources of problems.
iii. CO2 levels were checked three months ago.
iv. CO2 levels on “leave-in” devices, where present, where checked.
No Leave In devices
g. Offensive odors are not apparent.
If false, list problem areas:
h. Water damage is not evident.
Check for roof leaks, pipe leaks, spills, stained ceiling tiles, etc, visually and with moisture meter. Look
for the source of any water leaks and schedule repairs. Discard porous items such as ceiling tiles if wet
for more than 24 hours. For carpeting, if less than 9 square feet of wet area, shampoo with germicide
and fan dry. For areas greater than 9 square feet, replace carpet with tile in reasonable timeframe. If
carpet is over ACM tile, replace during next unoccupied break time (winter break, spring break,
summer).
If false, record findings and locations here: Water has been penetrating through the window in
Todd's office. We have not determined cause to date.

iii. CO levels in rooms with combustion appliances are measured and recorded with an IAQ monitor. CO
readings outside of normal CO range will result in an immediate response by maintenance to reduce
CO level or vacating the room/building, if necessary.

9. Other
a. Paint
No peeling and/or flaking paint found.
If planned building renovation will damage paint or if peeling paint is discovered, lead testing may be
necessary. If peeling paint is found, send email to the building Principal and the Facilities Director
alerting them of the problem. Staff and teachers need to pick up any flakes of paint to prevent
children from being exposed. The Facilities Director will advise the Facilities Coordinator (a Certified
Lead Paint Renovator) to test the paint for lead. Lead paint was discontinued in 1978. Buildings built
after 1978 are exempt from lead paint testing.
