Conflicting answers help. toddler broke cfl, we vacuumed, in room for 10 min before evacuating/venting. is this a big deal?

Maybe: The amount of mercury released by one bulb can temporarily exceed U.S. Federal guidelines for chronic exposure. Chronic, however, implies exposure for a significant time, and it remains unclear what health risks are from short-term exposure to low levels of elemental mercury. Despite following epa guidelines on broken cfls, researchers were unable to remove all mercury from carpets.

Not likely: Look, these protocols are in place to be as safe as we can with exposure to bad materials like mercury. However, an isolated, minor exposure is highly unlikely to cause any issues. Remember, your grandparents likely opened thermometers to play with pure mercury as children, like mine did. They are good rules to protect people as best we can but one small exposure is unlikely to be any risk for you.
