One of the worst hazards that I personally experienced in an office for one dozen years was polluted indoor air. There were many toxic chemicals from a material lab, repeated carpet glueing operations and fresh paints. In addition, so much fiberglass was also puffing out of the ceiling air registers that I could swipe up a mouse-sized wad from my desk top with one swipe.
However, worst of all, all of the fresh air intake louvers in the air handling units of our office building had been frozen in the closed positon for years and no ever changed the air filters
Years later, I am still suffering from this prolonged stupidity over which I had no control.
