What is the white stuff in a lightbulb?
The white powder that you see inside a fluorescent light bulb is called phosphor, which is a substance that emits visible light whenever it absorbs ultra violet energy waves. The phosphor used in a fluorescent light bulb is what determines both the color temperature and the color rendering index.
Is the stuff inside a light bulb toxic?
Broken fluorescent tubes and compact fluorescent bulbs DO contain mercury, a toxic metal. Follow the EPA’s guidelines for a safe clean up. Next, put all the broken glass, white powder from the tube, and the paper towel you wiped the area with, in a ziplock bag or sealed container.
What happens if you inhale mercury from a light bulb?

How long does it take for mercury to leave your body?
Mercury does not stay in the body forever. It takes about six months to a year to leave the bloodstream once exposure stops. Some researchers think mercury can permanently damage the nervous system in children.
What happens if mercury touches your skin?
Mercury is a very toxic or poisonous substance that people can be exposed to in several ways. If it is swallowed, like from a broken thermometer, it mostly passes through your body and very little is absorbed. If you touch it, a small amount may pass through your skin, but not usually enough to harm you.

How quickly does mercury evaporate?
Based on experiments conducted by the U.S. Environmental Protection Agency, the evaporation of mercury droplets in air was modeled as an exponential decay, and values for the decay constant, kd , were estimated; values for k −1d ranged from 0.7 days to 2.2 days over a temperature range of 302 K to 310 K.

Is mercury flammable?
Mercury is non-combustible. The agent itself does not burn, but it may react upon heating to produce corrosive and/or toxic fumes.
