Chlorine Safety

This online Chemical Safety course will help learners understand the risks of exposure to chemicals in the workplace and how to work safely in these environments.


Because the use of chlorine is so widespread, you may not think of chlorine as a dangerous chemical. However, in 2005, an incident in Graniteville, S.C., resulted in 18 freight train cars derailing and releasing 120,000 pounds of chlorine gas. 1,400 people were exposed, resulting in 550 hospitals visits, many with serious lung injuries. 5,000 people were evacuated from the surrounding area. Nine were killed.
