The Sick School

John had been a teacher in the same classroom for four years. He loved teaching but this was to be his last day, because he felt that he had become allergic to his classroom. The school was about 30 years old, and the classroom heating equipment had never been cleaned.

(Comment: The heating equipment contained large clumps of dust that had been there for decades. Much of the dust contained growing mold. John sealed all the openings and vents for the heating unit, and he was able to complete the year.)

Classroom heating and cooling units, called univents, always located at the exterior wall of a classroom, are rarely cleaned. During the hot and humid summer, when the classroom is closed up, mold often grows in the dust. When the blower operates in the winter, mold spores are blown into the classroom.
