North Carroll High School students were dismissed early yesterday after a ventilation fan malfunctioned, leaving a foul odor in many of the school's classrooms, school officials said. Students were evacuated about 10:40 a.m. after several teachers called the office to report an unusual smell. Students remained outside - and were moved to the school's stadium - before being bused home about 1 p.m. The problem was fixed by early afternoon and the school will open on time this morning.

Sick buildingsGrowing numbers of Americans are discovering that their fatigue, irritated throats or runny noses may be caused or aggravated by working in office buildings with inadequate ventilation systems.The rise of "sick building syndrome" began in the 1970s, when there was a national push to make buildings more energy-efficient. But sealing them tightly caused air quality problems.The Environmental Protection Agency defines sick building syndrome as a situation when occupants experience acute health problems and discomfort that appear to be linked to time spent in a building.

My attic has natural ventilation. It has triangular vents at the top side walls of my home. How do I know whether I have enough attic ventilation? My attic gets so hot in the summer, you can barely breathe up there. It is impossible to stay up there more than a few minutes. How much soffit ventilation should I have? What is the best way to cool my attic naturally without any electric-powered fans? I applaud you for trying to ventilate your attic the old-fashioned way. But without moving large amounts of air in a short amount of time through your attic space, I doubt you will ever get its temperature cool enough to make it tolerable to spend much time there.

Health inspectors found no traces of the bacteria that cause Legionnaires' disease at Clarence M. Mitchell Jr. Courthouse, the city's health commissioner said yesterday. Dr. Peter L. Beilenson said that inspectors took samples throughout the building after the disease was diagnosed in a court employee two weeks ago, and that all test results were negative. "It should help to reassure staff members," Beilenson said. He said he was surprised that the courthouse tests were clean. Most institutions have traces of the bacteria somewhere, he said.

The Investment Building in Towson was reopened yesterday after final tests showed no significant levels of airborne asbestos fibers. The 700 county and state workers assigned to the building were asked to return to work today, although some said they had grave concerns because of the building's troubled history. "I want written assurance regarding the safety of the building from the state and county, given the absence of concern regarding the health and welfare of their employees," said Deborah Veystrk, a supervisor with the county's Department of Social Services.

Since Aberdeen Proving Ground cleared a stockpile of deadly mustard agent last year, the distant booms of guns and occasional flashes of light have been the only reminders of the weapons testing taking place beyond the gates of the sprawling military base. But in two separate yet strikingly similar incidents this week, the reality of APG's dangerous mission resurfaced when power failures in a pair of chemical testing laboratories prompted concerns that employees could have been exposed to deadly substances when ventilation fans failed.
