What is sulfur dioxide?

Sulfur dioxide is a colorless pungent toxic gas formed by burning sulfur in the air. According to the EPA, short term exposures to SO2 can harm the human respiratory system and make breathing difficult. Those who suffer from asthma are particularly sensitive.

It is not known at this time how much of the gas leaked, or how it is being used on campus in the lab.
