Concern: River Hill High School: September 26th, 2018 (CXRHHS2018000054)

Room 148
Date of IEQ Report Form
Date of Report
December 20th, 2018
This is the only science room in the building that has carpet. I have been in the room for 9 years out of the 13 years its been used as a science classroom. Every year at the end of the year I ask them to remove the carpet and tile the floor like every other science room in the county and the answer is always no. In the morning there is a very potent smell. As the day goes on the smell decreases due to the air circulation. People from the county, head custodians, and administrators in charge of the building have all smelled the odor. The had the custodians shampoo the carpet and the smell is still there. The only reason I resubmitting this again is today students said that this classroom smelled like mildew in the morning. The students were sitting in the back of the room. We do science demos in this classroom. It should be tiled like every other science class in the county.
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)

The Office of the Environment visited the room early in the morning. No odors were identified.

No elevated moisture was detected in the carpet.

No thermal anomalies indicative of moisture intrusion were identified.

No mold growth was observed.

The plenum was assessed and was acceptable.

The ventilation unit that services the room was assessed and was acceptable.

Carpeted classrooms canĀ  have a nuisance odor early in the morning. The odor then becomes diluted by outside air, which is introduced through the ventilation system.

Removing the carpeting for the purposes of science demonstrations should be discussed with the school's administration.
