Every scientific discovery has its watershed moment. In indoor air quality, one of the great watershed moments in the awareness of indoor ozone came in 1983 when a student at the University of Colorado in Boulder wrote a paper for his science class about his summer job.
He titled it “Ozone Toxicity – How Copier Machines Made Me Sick.” The student had worked in a small windowless room in the university library. His job was to run off copies for the school’s professors. Soon, he developed headaches, a cough, irritated sinuses, and a myriad of other symptoms. Somehow, he got steered in the direction of what was making him sick. The copier machines were creating the lung irritant ozone, the main component of smog.
What no one could have expected was the domino effect that came next. The student took his paper to the local copy shop to have copies printed for his class. The copy shop workers saw the paper and made copies for themselves. Many of them had been experiencing the same problems, but they didn’t know what had caused their symptoms.
Soon, copies of the paper started to circulate to other shops that were part of the same national chain of copier stores. As awareness of the issue grew, the copier machines were fitted with ozone filters, ventilation was added to the shops, and copier maintenance companies began to stress the need to maintain the filters properly. The problem was corrected quietly – very quietly.
OZONE is a pollutant.. NOT a good thing..
