E. McCracken Middle School (SIC-8211), Hilton Head Island, South Carolina. The school was opened in the fall of 1991, serving grades 6 to 8. Approximately 1,100 persons occupied the building including students, faculty and support staff. The concern at the school was due to mold and mildew problems, and health symptoms reported by employees. Many persons reported fatigue, nasal congestion, headache, tension or nervousness and back, neck, or shoulder discomfort. Many of these same persons reported that their symptoms disappeared when they left the building. Too little air movement was a frequent complaint and temperature control was also a problem. Carbon-dioxide (124389) measurements used to asses the capabilities of the air handling system suggested that too little outside air was provided to occupied spaces. The authors conclude that a health hazard did not exist at the time of the survey. The authors recommend that the ventilation system be modified to provide additional outside air to occupied spaces.

The building was occupied by 280 persons, 17% of which were staff. Occupants reported a history of respiratory problems among teachers and students in the 5 year period before the current study. Respiratory problems included severe colds, bronchitis, and bouts of pneumonia. On site sampling revealed a significant disparity between the design of the ventilation system and the measured volumetric air flow values. Carbon-dioxide (124389) levels in most areas of the school increased over the course of the day. No significant levels of fungi, bacteria or thermoactinomycetes were located in the building. However, bulk carpet samples from select classrooms revealed varying concentrations of gram negative bacteria and yeasts characteristic of microbial proliferation due to elevated moisture conditions. The authors conclude that the higher prevalence of lower respiratory tract symptoms reported among workers in carpeted areas may be related to microbial contamination of the carpet. The authors recommend that the ventilation system be properly balanced, and microbially contaminated areas be remediated by removal of carpets.

Workers had expressed concern over poor air quality, temperature extremes, fire/electrical hazards, excessive noise, and other safety and ergonomic issues. Environmental measurements were made in the Toll free Telephone Area on the eighteenth floor and the tax collection area on the twenty first floor. Measurements of carbon-dioxide (124389) levels, temperature and relative humidity, and noise levels were made on the two floors over 3 days. The levels monitored were common for office buildings. Interviews and questionnaires were used to collect data from workers on the two floors. No significant elevations in the number of complaints were received when compared to other similar buildings and work forces. The authors conclude that there were no specific environmental concerns identified that would explain the reported symptoms. The authors recommend that specific measures be taken concerning ventilation, humidity, noise, safety and employee communications in the building.

(SIC-3442), Macedonia, Ohio, an environmental survey was conducted in the 700 and 720 office buildings of Patio Enclosures. Personnel working at the site had complained of eye problems, burning of the throat, and sinus problems. Patio Enclosures consisted of a large manufacturing area with two story office areas at the east and west ends. Average temperatures in the office ranged from 69.2 to 74.9 degrees-F during the morning and from 69.1 to 75.3 degrees in the afternoon. Average relative humidity ranged from 15.0 to 21.2% during the morning and 18.0 to 23.3% in the afternoon. Average carbon-dioxide (124389) concentrations ranged from 375 to 850 parts per million (ppm) in the morning and 500 to 850ppm in the afternoon. Visible microbial growth was present in some of the air handling unit drip pans. Analysis revealed several species such as Penicillium, Cladosporium, Aspergillus, Alternaria, yeasts, Ulocladium, and Fusarium. Smoking was permitted in the private offices which then circulated to other areas served by the same units. The author concludes that a potential health hazard existed due to the recirculation of environmental tobacco smoke throughout the offices. Microbial growth in the ventilation system could be aerosolized and distributed throughout the building. The author recommends that a no smoking policy be established, and cooling coil condensate pans and drains be cleaned.

The school building housed about 2,000 students and 200 staff. Faculty and students reported allergy and asthma problems, along with irritation of the nose, throat, and eyes. When not in the building, their symptoms subsided. A medical questionnaire was distributed and an environmental evaluation was begun of two areas in the school, the office area and one of the classroom wings. One or more symptoms, which decreased when absent from the building, were reported by 57% of those completing the questionnaire. Carbon-dioxide (124389) levels exceeding 1,000 parts per million were noted in the evaluated classroom wing, suggesting an inadequate supply of outside air. Inspection of the air handling equipment revealed a significant amount of microbial growth on the drain pans. The author concludes that some environmental deficiencies were identified, as well a major problem with ventilation system maintenance. The author recommends that the air supply system be cleaned up, and its performance improved.

Concern was expressed regarding high humidity levels, breathing problems, burning eyes, and a lack of air conditioning. Based on a visual inspection of the air conditioning and heating system, increased maintenance was needed. An abundance of visible microbiological growth was noted on the interior of the air handling unit (AHU) mixed air plenum, and the pneumatic linkage for the return air damper was disconnected. An abundance of fungi and bacteria were noted in the analysis of bulk material samples collected from the AHU mixed air plenum. In some cases the measured airflow volume was less than 50% of the adjacent slot diffusers, indicating the air distribution was not balanced, perhaps resulting in the comfort complaints. Temperature measurements exceeded suggested comfort ranges for winter months. Some carbon-dioxide (124389) measurements exceeded the 1,000 parts per million ceiling recommendation. The author concludes that there were significant deficiencies in the indoor environment that may be related to reported symptoms and comfort complaints. The author recommends that improvements be made in the ventilation system, and that a system maintenance program be implemented.

Environmental monitoring studies were conducted approximately 18 months after the lead abatement activity had been completed. No lead was detected in any of the twelve general area samples taken for airborne lead. Two bulk samples of residue abrasive blasting and paint chips material contained 3,300 and 120,000 micrograms of lead/gram of material. Forty wipe samples obtained from surfaces in the office ranged from 9 to 200,000 micrograms of lead/square foot. The authors conclude that a potential health hazard existed due to the presence of lead contaminated dust. The authors recommend that manual cleaning and vacuuming of these areas using a high efficiency particulate air filtering system be conducted.

The original study had been made at this site 2 years earlier. In some sections of the school the carbon-dioxide (124389) levels had decreased by 52% from levels recorded during the previous survey. The major recommendation of the earlier study was to increase the induction of outside air. Relative humidity levels were still below the recommended range, averaging below 30% at the 1994 study. Formaldehyde (50000) levels ranged from 0.02 to 0.04 parts per million (ppm) in 1992 and 1993, and had dropped to less than 0.002 to 0.007ppm in the current study. Total volatile organic compounds (TVOCs) arising from the use of photocopiers, ranged from less than 0.08 to 11.4mg/m3, down from 1.6 to 18.3 mg/m3 in 1992. The rate of symptoms experienced by the employees dropped from 26% in 1992 to 10% in 1994 since the installation of an auxiliary ventilation system. The authors conclude that a health hazard was not identified during this follow up evaluation. The authors recommend that TVOC levels be further reduced, and that the auxiliary ventilation systems be tested and balanced.

Complaints about air quality had begun shortly after the building was first occupied in 1991. Major complaints from the workers were centered on comfort related issues such as too hot, too stuffy, and noticeable odors being present. Health problems included headache, stuffy or runny nose, burning or itchy eyes, and several miscellaneous symptoms. The three story office building had about 50,000 square feet of office space and 200 occupants. The ventilation consists of a central system providing heated and cooled air to 78 zones. The system was shut down overnight. After occupant complaints, the system was set to operate with 100% outside air. At the time of the study, humidity and carbon-dioxide levels were all within the recommended limits. However, there have been occasions where the humidity levels were as low as 10%. The only deficiencies noted were the finding of standing water in the condensation drip pans and the fact that the ventilation system might be turned off while workers are inside the building outside normal working hours. The author concludes that no airborne contaminants were identified which would constitute a health hazard. The author recommends measures to help alleviate worker complaints.

Chronic respiratory illness and the presence of mold in the building were two of the most frequent complaints. The windowless building was arranged in pods. The school had 806 students in kindergarten through sixth grade, and employed 69 workers. Moisture from a chronically leaking roof has long been a problem at this school, causing mold and mildew. Interviews were conducted with 24 teachers and one cafeteria worker concerning environmental symptoms. Moldy odors were noted in many of the classroom pods and the source was thought to be wall board on the interior side of the outside walls. Considerable mold growth and water damage was visible on removal of wall paper in selected areas. Relative humidity levels were at the high end of acceptable. Insufficient outside air was being provided as evidenced by the carbon-dioxide (124389) levels, exceeding 1,000 parts per million (ppm) in most areas. Air flow measurements were less than adequate. The authors conclude that the presence of mold contaminated wall board and ceiling tile is a potential source of microbial contaminants. Insufficient outside air and high relative humidity levels were found. The authors recommend that steps be taken to improve the quality of indoor air and address the environmental concerns.
