e. Occupied space readings of carbon monoxide (CO) levels are less than 9.0 PPM.
Outdoor Air CO Reading: 0 both days
Highest CO Location: Several Rooms; 93, 306 Reading: .2; .1
Lowest CO Location: Several Rooms
Reading: 0
If the CO level is greater than 9.0 PPM in any space as measured with a handheld device or “leave-in”
monitor, the space must be cleared of all occupants and steps taken to correct the problem. The issue
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 + 436; 382 PPM = 1136; 1082 PPM
Assume outside CO2 is 350 if temperature is below 41 degrees and air is not stagnant with no- wind.
Record all occupied space CO2 levels on forms provided. Provide the outdoor CO2 level as well as
the high and low CO2 extremes below:
Outdoor reading: 436; 385 PPM
Highest CO2 reading – Location: 405; 405; Reading of 1332; 937 PPM
Lowest CO2 reading – Location: 106; 306; Reading of 436; 541 PPM
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

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.
If lead is present, required repairs should be done immediately using lead-safe methods and, if
necessary, a licensed lead contractor.
Location(s) of known peeling paint in building:
b. The following preventive measures are being taken to reduce lead exposure.
i. Play areas and toys are cleaned nightly.
