What happens if a CFL light bulb breaks?
Despite some alarming news reports, you don’t have much to worry about. If a CFL breaks, some of the mercury that’s contained in the bulb will evaporate into the air.
Can one broken CFL bulb cause mercury poisoning?
Persons in rooms after breakage of a CFL may be exposed to mercury by inhalation and by oral intake. After inhalation, more than 80% of inhaled Hg0 vapour is absorbed by the lungs. Ingested Hg0 is poorly absorbed in the gastrointestinal tract (less than 0.01%).
How much mercury is in a CFL?
about four milligrams
CFLs contain very small amounts of mercury On average, CFLs contain about four milligrams of mercury sealed within the glass tubing. By comparison, older thermometers contain about 500 milligrams of mercury – an amount equal to the mercury in over 100 CFLs.
Can you touch CFL bulbs?
Yeah, you might snap the tube if using it to screw or unscrew it (grab it by the base), but there’s not going to be any danger in touching the tube.
Do CFL bulbs contain mercury?
A CFL bulb is made of glass, a ceramic and metal base, a powder called phosphor, and a small amount of mercury. The mercury in the bulb is in the form of an invisible vapor or as part of the phosphor coating on the inside of the glass. CFL bulbs use less energy than a regular light bulb.
Can a broken CFL make you sick?
Is it harmful to be in the room where a CFL bulb has broken? The amount of mercury vapor that is released from one broken CFL bulb is not enough to make anyone sick. However, to avoid any exposure to mercury, we recommend that you leave the room for at least 15 minutes before cleaning up the broken bulb.
How long does mercury vapor stay in a room?
one year
They can go through small cracks or become strongly attached to certain materials. At room temperature, exposed elemental mercury can evaporate to become an invisible, odorless toxic vapor. This vapor has a very long life (up to one year) in the air.
What happens if I crack a light bulb?
If the glass breaks, then technically, the bulb will still work – for an extremely short amount of time (I mean a few seconds). And it would be dangerous due to the exposed high temperatures. In reality, a broken bulb will burn out almost immediately, and you’ll need to replace it.
What happens if I break a fluorescent tube?
When broken, mercury vapors may be released into the air. 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.
How far does mercury vapor travel?
At room temperature, exposed elemental mercury can evaporate to become an invisible, odorless toxic vapor. This vapor has a very long life (up to one year) in the air. Once released into the wider atmosphere, elemental mercury can travel thousands of miles and becomes part of a global pool of atmospheric mercury.
How do you remove mercury from a house?
Isolate the spill and ventilate the area Close all doors between the room with the spill and the rest of the house. Use fans to blow mercury-contaminated air outside. Close or cover all heat vents and cold air returns. Turn off fans that don’t vent outside.
How do you handle a broken CFL?
DO NOT VACUUM.
- DO NOT VACUUM. Vacuuming is not recommended unless broken glass remains after all other cleanup steps have been taken.
- Be thorough in collecting broken glass and visible powder. Scoop up glass fragments and powder using stiff paper or cardboard.
- Place cleanup materials in a sealable container.
How long does it take to get mercury after exposure?
Poisoning from methylmercury can take weeks or months to appear. A chemical spill with elemental mercury or inorganic mercury might give you symptoms more rapidly. Mercury poisoning is diagnosed by testing your blood and urine for mercury levels. Urine might be collected over a 24-hour period.
