Quick Answer: Is the gas in a fluorescent light bulb poisonous?

Can you get mercury poisoning from a fluorescent 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. … (By contrast, a mercury-containing fever thermometer contained about 500 mg.) Mercury can cause poisoning in some circumstances.

What happens if you breathe in a broken fluorescent bulb?

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%).

Are the chemicals in fluorescent lights toxic?

Compact fluorescents, like their tubular fluorescent precursors, contain a small amount of mercury—typically around five milligrams. … As effective as it is at enabling white light, however, mercury—sometimes called quicksilver—is also highly toxic. It is especially harmful to the brains of both fetuses and children.

What happens if you break a fluorescent light tube?

Fluorescent bulbs contain a small amount of elemental mercury, typically between 2 and 5 milligrams in common four-foot tubes and about the same for most compact fluorescent lamp (CFL) bulbs. When broken, mercury vapors may be released into the air. The mercury released from broken bulb is mostly in vapor form.

What happens if you inhale mercury from a light bulb?

Mercury in CFLs are present as elemental (or metallic) mercury. Once inhaled, the mercury vapor can damage the central nervous system, kidneys, and liver. These toxic effects are why any mercury spill should be handled carefully, including one that results from a CFL breaking.

Is the inside of 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.

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 is in a fluorescent bulb?

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.

Do fluorescent lights give off radiation?

The compact fluorescent industry says the bulbs are safe but admits they do emit UV rays. … In a statement they insist, “the levels of UV radiation emitted are acceptably low” and are safe under normal use.

Do fluorescent lights cause health problems?

Fluorescent lighting may increase UV-related eye diseases by up to 12% and, according to our calculations, may cause an additional 3000 cases of cataracts and 7500 cases of pterygia annually in Australia. Greater control of UV exposure from fluorescent lights is required.
