Question: What To Do When A Fluorescent Bulb Breaks

Wipe up the broken glass and powder, seal them in a container and dispose of them. Check with your local government about disposal requirements. Some communities require that trashed fluorescent bulbs (broken or unbroken) be taken to a local recycling center.

Is it dangerous if a fluorescent bulb breaks?

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 dangerous is a broken compact fluorescent bulb?

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.

What happens if you inhale mercury from a light bulb?

Mercury vapor is released when the bulb is broken. Inhaling mercury vapor is hazardous to your health. Breathing in mercury vapors may cause symptoms such as cough, fever, difculty breathing, nausea, vomiting, headaches, increased salivation and an acute metallic taste in the mouth.

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.

What’s inside a fluorescent tube?

A fluorescent lamp consists of a glass tube filled with a mixture of argon and mercury vapour. The inside of the tube is coated with phosphors, substances that absorb ultraviolet radiation and fluoresce (reradiate the energy as visible light).

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. Bulbs manufactured in the mid-1980s and earlier con- tained 40 mg or more. Low-mercury bulbs, containing 4 mg or less, are currently produced by at least one manufacturer.

What is the dust in fluorescent bulbs?

The white powder coating inside the glass tubing of a CFL contains a fluorescent coating. When electricity enters a CFL, mercury and argon fumes inside the bulb produce invisible ultraviolet (UV) light. This UV light reacts with the fluorescent coating to produce the white, visible light you see when you turn on a CFL.

What is the white powder in fluorescent tubes?

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.

How long does mercury vapor stay in the air?

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 you breathe in fluorescent?

The parts of the body most affected by mercury inhalation are the kidneys and the central nervous system. People who have accidentally inhaled relatively large quantities of vapours – for instance at certain workplaces – often show inflammation of the lungs, kidney damage, gastroenteritis, restlessness and shaking.

How long does it take for mercury to dissipate?

A pea-sized drop of mercury that goes undetected can take up to 384 days to fully vaporize. In that amount of time, it can cause severe neurological damage—especially in infants and children.

Can you touch fluorescent light bulbs?

YES! You should not touch halogen capsule bulbs with your fingers. Halogen bulbs, tubes and capsules are made of quartz, rather than ordinary glass, so they can withstand the higher temperatures.

What is the normal life of a fluorescent lamp?

Typical Average Rated Life for Various Types of Bulbs Incandescent 750-2,000 hours Fluorescent 24,000-36,000 hours HID 10,000-24,000 hours Compact Fluorescent Plug-in 10,000-20,000 hours.

Why do fluorescent lights flicker?

In your lighting system, the ballast regulates the current flowing to the fluorescent lights and provides the voltage needed to start the lamps. The ballast takes in electricity and then regulates current throughout the bulbs. This is why a degrading ballast will cause the fluorescent lights to flicker.

Can a fluorescent light work without a starter?

Can a fluorescent lamp work without a starter? Some modern fluorescent lights do work without a starter because they come pre-equipped with a ballast that has extra windings. It constantly supplies a small amount of voltage to give heat to the filaments.

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 regular 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.

Is fluorescent light good for plants?

Fluorescent lights are ideal for plants with low to medium light requirements, like African violets. They are also good for starting vegetables indoors. In addition to this, fluorescent bulbs use 75 percent less energy than incandescent lights.

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.

Are fluorescent lights a fire hazard?

Overheated fluorescent lights can cause fires! Overheating of the ballast could result in the following: Ignition of nearby combustible materials. Explosion of the ballast due to the generation of gases inside.
