Can you get mercury poisoning from broken light bulb?
Compact fluorescent light bulbs (CFLs) contain small amounts of mercury. A small percentage of this mercury can be released into the air if the bulbs are broken. Mercury can cause poisoning in some circumstances. Even so, people are encouraged to replace their “old fashioned” incandescent bulbs with CFLs.
Is mercury from a light bulb dangerous?
Overexposure to the elemental mercury in certain types of light bulbs can be fatal. Extended exposure to mercury can result in respiratory or kidney failure. Death can also be a side effect of overexposure to elemental mercury. People that have been exposed to any level of mercury should seek medical help immediately.
What happens if you break a mercury light bulb?
If you break a mercury thermometer or light bulb, a small amount of liquid mercury may spill out. Liquid mercury can separate into small beads, which can roll some distance away. The mercury may also evaporate into vapour. However, this small amount of mercury is extremely unlikely to cause problems for your health.
Do light bulbs emit mercury?
On average, CFLs contain about four milligrams of mercury sealed within the glass tubing. No mercury is released when the bulbs are intact (i.e., not broken) or in use, but mercury vapor and very small beads of mercury can be released when a CFL is broken.
How much mercury is toxic?
Symptoms include tremors, insomnia, memory loss, neuromuscular effects, headaches and cognitive and motor dysfunction. Mild, subclinical signs of central nervous system toxicity can be seen in workers exposed to an elemental mercury level in the air of 20 μg/m3 or more for several years.
Is it bad to inhale a broken light bulb?
Once broken, a compact fluorescent light bulb continuously releases mercury vapor into the air for weeks to months, and the total amount can exceed safe human exposure levels in a poorly ventilated room, according to a new study.
How much mercury vapor is dangerous?

Why is mercury used in light bulbs?
Mercury is useful in lighting because it contributes to the bulbs’ efficient operation and life expectancy. Fluorescent and other mercury-added bulbs are generally more energy efficient and last longer than incandescent and other equivalent forms of lighting.
What happens if mercury is swallowed?
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.

CFLs contain mercury, a potentially dangerous substance that escapes from broken CFLs into the immediate surroundings, and therefore the breakage of a CFL bulb should be handled by carefully removing the broken bulb and its contents from a home.
What are the facts about broken light bulbs and Mercury?
The Facts about Light Bulbs and Mercury. Some news reports have raised concerns that broken CFLs could result in harmful air concentrations of mercury in the room where the bulb is broken, but these reports are based on worst-case situations, assuming common sense measures (such as ventilating the room) are ignored.
