A Hazmat team has closed San Jose Valley Medical Center's emergency room after an unknown chemical exposure. At least 37 employees, 47 patients were given Silkwood scrubdowns. The toxic mess, it seems, came from a nearby house. According to the Mercury News, "they don't know what kind of toxic substance was released around 8:05 a.m. inside a house on the 3000 block of Yucca Avenue. A barrage of hazardous materials crews are on scene trying to sort out the mess, police and fire dispatchers said." Also, the Merc is reporting that an 18-year-old man died this morning, possibly due to the spill. We'll update as soon as we know more.
