The mercury released from broken bulb is mostly in vapor form. If properly cleaned up, broken bulbs or CFLs do not pose a serious health risk. Though the amount of mercury released from a broken tube or CFL is small, proper disposal of the broken tube or CFL and minimization of personal exposure are necessary.
What happens if you break a fluorescent light bulb?
Compact fluorescent light bulbs (CFLs) use dramatically less energy than incandescent bulbs and reduce greenhouse gas emissions. But they also contain mercury – a dangerous toxin. If a CFL breaks, some of the mercury that’s contained in the bulb will evaporate into the air.
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.
How much mercury is in a 4 foot fluorescent bulb?
The average mercury content of a 4-foot-long bulb manufactured today is approximately 12 mg.
How much mercury is in fluorescent tubes?
The amount of mercury in a fluorescent lamp varies from 3 to 46 mg, depending on lamp size and age. Newer lamps contain less mercury and the 3–4 mg versions are sold as low-mercury types.
Can you get mercury poisoning from fluorescent bulb?
Why are fluorescent tubes hazardous?
Fluorescent tubes can be very harmful to the environment, wildlife and even humans. Any variety of fluorescent lighting contains mercury, a highly toxic metal. If incorrectly disposed of, mercury can dissipate into the atmosphere which allows it to contaminate water supplies and wildlife.
Do modern fluorescent tubes have mercury?
The amount of mercury in a fluorescent lamp varies from 3 to 46 mg, depending on lamp size and age. Newer lamps contain less mercury and the 3–4 mg versions are sold as low-mercury types. A typical 2006-era 4 ft (122 cm) T-12 fluorescent lamp (i.e. F34T12) contains about 5 milligrams of mercury.
Do all fluorescent bulbs contain 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.
