how to report hazardous substance spills.

Mercury is a hazardous material that causes serious environmental and human health problems. Although it is found naturally, it is most often released from man-made products like thermometers and fluorescent lights, or produced as a by-product of energy production. Mercury is a bio-accumulative pollutant, which means that it does not break down over time and accumulates in animal tissues.

Report all mercury spills immediately by calling the 24-hour, toll free hotline at 1-800-943-0003.
