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: .2; 2.5; 0; 1.1; 0
Highest CO Location: All rooms each day Reading: 0
Lowest CO Location:
Reading:
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 + 350 PPM = 1050 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: 397; 385; 360; 426; 395 PPM

Lowest CO2 reading – Location: F106; B115; E201; PA131; PPS102; Reading of 471; 441;
556; 499; 565 PPM
Work orders were written to respond to high readings above the base line. We are currently
upgrading our operating system and as a result will be able to better see problems. Also we are
going room by room and identifying specific issues with each room.
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.
The Food Lab now has 2 leave-in CO devices.
g. Offensive odors are not apparent.
If false, list problem areas: There several reports of rotten egg type smells particularly in the B
Wing. This was the result of dry floor drains and it was addresssed by appropriate treatments.
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).

No peeling and/or flaking paint found.
If planned building renovation will damage paint or if peeling paint is discovered, lead testing may be

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
