UCLA’s Office of Environment, Health and Safety responded Friday morning to a mercury spill on the loading dock area of Young Hall after an unknown person illegally disposed of it in a campus dumpster. The mercury was cleared away by 5 a.m. Saturday morning. No health impacts are anticipated.

Before EH&S discovered and roped off the spill at 6:30 a.m. Friday, 45 UCLA employees may have walked in the area. They were tested and cleared for return to work. No mercury went into storm drains or otherwise drained away.

UCLA EH&S hazardous materials teams and a hazardous materials cleanup company cleaned approximately 50-100 milliliters of mercury on the dock area, and an estimated 50-100 milliliters more in the dumpster. UCLA is investigating who illegally disposed of the mercury and, in accordance with state policies, has notified California’s Office of Emergency Services.
