Concern
At times there is a mechanical odor in the air or there is another odor to the room, MANY ants have been observed in the back corner near the vent and I am coughing/ sneezing/ congested. Last night I found that after being in the room I have a skin rash.
IEQ Investigation Process

Identify deficiencies that may impact IEQ and/or sources of odor concerns. Typically includes the following depending on the nature of concern, but not limited to:

  • interview/questionnaire of concern individual(s)
  • inspection above drop ceiling (condition of roof deck, pipe insulation, return air plenum)
  • inspection of ventilation system (operation of variable air volume box and outdoor air dampers, check controls, measurements of carbon dioxide, temperature and relative humidity, sources near outdoor air intake, measure return and supply air volume, cleanliness of coils, liner and condensate pan)
  • inspection of exterior
  • inspection below drop ceiling (housekeeping, sink and floor drain traps, signs of past and present moisture concern via visual and/or moisture meter, mold growth, ensure connection of current and capping of abandoned sanitary vents, odorizers, excessive plants and fabric items, identify potential pathways, and measure volatile organic compounds, carbon monoxide, and lighting)
Findings

Date(s) of Assessment: August 28, 2024

The temperature (75.8 degrees Fahrenheit (F)), relative humidity (51.6%), carbon dioxide (474 parts per million (parts per million)), and carbon monoxide (0.0 ppm) were acceptable. 

Surfaces were assessed for visible mold growth. No visible mold growth was observed. 

An odor consistent with fiberglass was present (prior to Heating Ventilation and Air Conditioning (HVAC) operation). This is consistent with the room having fiberglass ceiling tiles. This odor would be diluted once the HVAC begins operation. 

The carpet was probed in various locations with a moisture meter. No elevated moisture was detected. 

While assessing near the teacher desk, a gap was observed between the wall and concrete slab. This gap could serve as a way for pests to travel. 

The space was screened with a thermal infrared camera. No thermal anomalies indicative of moisture intrusion were present. 

The supply diffusers were assessed. dust was observed on the topsides of the diffusers. 

The cabinets were locked and were not accessible at the time of the assessment. 

The HVAC unit that serves the space was assessed. The following was noted:

  • The outside air dampers were open.
  • The filters were in place and in good condition.
  • No concerns were identifed with coils or condensate drain. 

While on the roof assessing the HVAC system, missing caulk was noted in a location near the HVAC unit. 

Corrective Actions
August 30th, 2024

A work order was created for Building Maintenance (HVAC) is to assess the rooms VAV box to ensure proper operation. 

August 30th, 2024

A work order was placed to Building Maintenance to address the dust on the top sides of the supply diffusers in the space. 

August 30th, 2024

Although no pests were observed during the visit, an IMP work order was placed to further assessment of the reported ants. As part of this, the gaps between the slab/wall is to be sealed. 

August 30th, 2024

Although likely unrelated to the concern, a work order was placed for Building Maintenance to re-caulk and area of the roof. 

September 20th, 2024

A request to perform a deep cleaning of the carpet using wet methods was submitted to Custodial Services. The cleaning was reported to be conducted on September 24, 2024.
