Is fluorescent light bulb a hazardous substance?
Fluorescent Lamps, including compact fluorescent lights, contain mercury, a toxic metal. When a lamp is broken or placed in a landfill or incinerator, the mercury can contaminate the airs, surface water, and ground water. UNC promotes recycling of fluorescent bulbs, and has a system in place to recycle them.
What do you do if a fluorescent tube breaks?

Some communities require that trashed fluorescent bulbs (broken or unbroken) be taken to a local recycling center.
Can you get mercury poisoning from 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.
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.
What hazardous material do fluorescent light bulbs contain?
mercury
The danger with these bulbs is that they contain small amounts of mercury, a potent, developmental neurotoxin that can damage the brain, liver, kidneys and central nervous system, especially in infants and young children.
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. A typical 2006-era 4 ft (122 cm) T-12 fluorescent lamp (i.e. F34T12) contains about 5 milligrams of mercury.

Can a light bulb start a fire?
Yes, it can! Any kind of light bulbs, from fluorescent to incandescent to halogen, can cause fires if they are not used correctly.
Why do fluorescent lights burn out?
Every time a fluorescent lamp is turned on in a cold state, more emission mix is used to get it going. That means lamps that are turned on for lesser periods of time — usually less than a three-hour time period — will find themselves burning out due to less emission mix than those that are kept on for a longer time.
Are fluorescent bulbs regulated waste?
Under the federal UWR, spent fluorescent bulbs and lamps that are intact and are going to be recycled have relaxed regulatory requirements. Like RCRA’s hazardous waste rules, generators of universal waste are divided into categories. Small quantity handlers accumulate less than 5,000 kg of universal waste at any time.
How to dispose of fluorescent light bulbs?
Fluorescent tube bulbs can generally be recycled at the same sites that take used CFL bulbs, but some retailers may not accept larger ones. Check Earth911 for your area and call ahead to be sure, or take your used fluorescent tube bulbs to your nearest household hazardous waste site.
How do you recycle a fluorescent bulb?
Businesses now manage mercury-containing lamps and tubes as universal wastes for recycling.
How should you recycle your old fluorescent light bulbs?
– Some light bulbs have risky materials that can pollute water and the earth. – Your curbside recycling facility might get light bulbs; however, do your study to find out the right site to recycle light bulbs. – Some countries and local jurisdictions implement laws that order light bulb disposal.
