35; 38.9; 36.9; 47.4; 59.8 %
Readings not within acceptable standards will result in the creation of a work order, requesting
maintenance to address. (Readings are noted on the attached test data sheet)
e. Occupied space readings of carbon monoxide (CO) levels are less than 9.0 PPM.
Outdoor Air CO Reading: 0
Highest CO Location: Cafeteria Reading: .2;
Lowest CO Location: All 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 + 375; 364; 380; 348; 360 PPM = 1075; 1064; 1080; 1048; 1060

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: There has been a report of natural gas in the building. We are
investigating with a consultant to rectify as the situation appears to involve the direction of wind
and air intakes.
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).
