  • Never use a vacuum cleaner to clean up mercury. The vacuum will put mercury into the air and increase exposure. Never use a broom to clean up mercury. It will break the mercury into smaller droplets and spread them. Never pour mercury down a drain. It may lodge in the plumbing and cause future problems during plumbing repairs. If discharged, it can cause pollution of the septic tank or sewage treatment plant.
  • Never wash clothing or other items that have come in direct contact with mercury in a washing machine, because mercury may contaminate the machine and/or pollute sewage. Clothing that has come into direct contact with mercury should be discarded. By "direct contact," we mean that mercury was (or has been) spilled directly on the clothing, for example, if you break a mercury thermometer and some of elemental mercury beads came in contact with your clothing. Never walk around if your shoes might be contaminated with mercury. Contaminated clothing can also spread mercury around.
  • NOTE: these instructions also apply to spills from other sources, if the amount spilled is less than or similar to the amount in a thermometer (see specific information about how to clean up broken fluorescent bulbs)
  • Put on rubber, nitrile or latex gloves.
  • If there are any broken pieces of glass or sharp objects, pick them up with care. Place all broken objects on a paper towel. Fold the paper towel and place in a zip lock bag. Secure the bag and label it as directed by your local health or fire department.
  • Locate visible mercury beads. Use a squeegee or cardboard to gather mercury beads. Use slow sweeping motions to keep mercury from becoming uncontrollable. Take a flashlight, hold it at a low angle close to the floor in a darkened room and look for additional glistening beads of mercury that may be sticking to the surface or in small cracked areas of the surface. Note: Mercury can move surprising distances on hard-flat surfaces, so be sure to inspect the entire room when "searching."
  • Use the eyedropper to collect or draw up the mercury beads. Slowly and carefully squeeze mercury onto a damp paper towel. Place the paper towel in a zip lock bag and secure. Make sure to label the bag as directed by your local health or fire department
  • it makes the mercury easier to see since there may be a color change from yellow to brown and (2) it binds the mercury so that it can be easily removed and suppresses the vapor of any missing mercury. Where to get commercialized sulfur? It may be supplied as mercury vapor absorbent in mercury spill kits, which can be purchased from laboratory, chemical supply and hazardous materials response supply manufacturers
  • OPTIONAL STEP: It is OPTIONAL to use commercially available powdered sulfur to absorb the beads that are too small to see. The sulfur does two things: (1
  • Alternatively, use duct tape to collect smaller hard-to-see beads. Place the paint brush or duct tape in a zip lock bag and secure. Make sure to label the bag
  • as directed by your local health or fire department.
  • After you remove larger beads, put shaving cream on top of small paint brush and gently "dot" the affected area to pick up smaller hard-to-see beads.
  • Note: Powdered sulfur may stain fabrics a dark color. When using powdered sulfur, do not breathe in the powder as it can be moderately toxic. Additionally, users should read and understand product information before use.
  • If you choose not to use this option, you may want to request the services of a contractor who has monitoring equipment to screen for mercury vapors. Consult your local environmental or health agency to inquire about contractors in your area. Place all materials used with the cleanup, including gloves, in a trash bag. Place all mercury beads and objects into the trash bag. Secure trash bag and label it as directed by your local health or fire department.
  • Contact your local health department, municipal waste authority or your local fire department for proper disposal in accordance with local, state and federal laws.
  • Cleanup Instructions 1. Have everyone else leave the area; don't let anyone walk through the mercury on their way out.2. Open all windows and doors to the outside.3. Turn down the temperature.4.

  • CFL containing 5 mg of mercury breaks in your child’s bedroom that has a volume of about 25 m3 (which corresponds to a medium sized bedroom). The entire 5 mg of mercury vaporizes immediately (an unlikely occurrence), resulting in an airborne mercury concentration in this room of 0.2 mg/m3. This concentration will decrease with time, as air in the room leaves and is replaced by air from outside or from a different room. As a result, concentrations of mercury in the room will likely approach zero after about an hour or so.

      Very Very Dangerous!!!!!!!!!!!!! :( DONT INHALE!!!!!!!!!!!!
  • elemental mercury vaporizes readily (essentially becomes a gas) and can thus be inhaled into your lungs. Breathing elemental mercury into your lungs is generally more dangerous than if you ate the mercury or absorbed it through your skin. 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
  • This is because CFLs contain relatively small amounts of mercury -- EPA estimates this amount to be 4-5 milligrams (mg) in a typical CFL
  • . A spill of this amount of mercury is not likely to present any excess risk to you or your family
  • Under these relatively conservative assumptions, this level and duration of mercury exposure is not likely to be dangerous, as it is lower than the US Occupational Safety and Health Administration (OSHA) standard of 0.05 mg/m3 of metallic mercury vapor averaged over eight hours. [To equate these values, we could estimate the average indoor airborne mercury concentration for 8 hours, beginning post-spill at an estimated starting value of 0.2 mg/m3 and decreasing from there. If one assumes the the air exchanges completely in one hour (a fairly standard assumption), then the 8-hour average concentration would be 0.025 mg/m3.]
  • Even though mercury from the broken CFL is not likely to be dangerous, it would be wise to take extra precautions to minimize mercury exposures
  • The US EPA publishes guidelines about the specific steps that you should take to clean up mercury in the event that a CFL breaks in your home
  • Briefly, EPA recommends that (1) you immediately open windows to reduce mercury concentrations inside your home; (2) you do not touch the spilled mercury; (3) you clean up the broken CFL glass carefully and immediately (but not with your hands or a vacuum cleaner), and (4) you wipe the affected area with a paper towel to remove all glass fragments and mercury. EPA further recommends that you place the paper towel and glass fragments in a sealed plastic bag and bring the sealed bag to your local Household Hazardous Waste (HHW)Collection Site.

  • Elemental (metallic) mercury: shiny, silver, odorless liquid used in thermometers. It is absorbed by the body through vapors. Organic mercury: mercury combined with carbon. Methyl mercury is a common form of organic mercury. These forms of mercury are soluble in lipids and cross the blood brain barrier and placenta easily. Organic mercury is absorbed through the digestive tract and also through vapors.
  • Mercury is a natural material found in the earth. Some mercury vapors are given off during volcanic eruptions. Mercury is a by-product of coal-burning power plants. Mercury is released into the air, then it falls back to the earth. Mercury is used by mining operations to separate gold from impurities in ore. Mercury is used during the manufacture of various products. For example, before 1990, mercury was added to paint.

  • Eat food (especially fish) or drink water that has been contaminated by mercury
  • Absorb mercury through the skin. Glass thermometers contain mercury that should be cleaned up properly
  • Eat objects that contain mercury. For example, small children may eat batteries that contain mercury. Broken high power lights and long fluorescent tubes can also contain mercury. Small amounts of mercury from these sources may be ingested accidentally.
  • Minamata Bay (Japan): Organic mercury was dumped into Minamata Bay in the 1950s. Fish in the bay were contaminated and about 2,000 people who ate these fish became poisoned. About 7% of the children born to mothers who ate contaminated fish had neurological problems. Symptoms in these children included uncoordinated movement, abnormal reflexes, seizures and speech problems. Some adults also had neurological problems such as visual disorders, shaking (tremors), weakness, nausea, hearing loss, depression, confusion, loss of appetite and memory problems. A total of 46 people died as a result of mercury exposure.
  • Iraq: In 1972, approximately 6,500 people fell ill and 459 people died after eating bread baked with wheat contaminated with a mercury-based fungicide.
  • Faroe Islands (North Atlantic): A study started in 1984 investigated the effects of methyl mercury exposure on children born to mothers who ate contaminated whale meat. Researchers found that children (seven years old) who were born to mothers with a 10-20 ppm mercury count had lower language, attention and memory scores than those children born to mothers with lower mercury levels. Interestingly, a study performed in the Seychelles Islands (Indian Ocean) did not reveal any effects on children born to mothers who had mercury hair levels of 10 ppm.
  • Take off any jewelry so you don't contaminate it. Scoop up the mercury with a sheet of cardboard. Place the mercury in a small bottle or vial. Cap the bottle or vial. Dispose of the bottle or vial properly. Many communities have special hazardous waste disposals or pick-up locations. Wash your hands! NEVER use a vacuum cleaner to clean up mercury spills. A vacuum cleaner will get contaminated and will spread mercury vapors into the air.

  • Common symptoms include peripheral neuropathy (presenting as paresthesia or itching, burning or pain), skin discoloration (pink cheeks, fingertips and toes), edema (swelling), and desquamation (dead skin peels off in layers).
  • Because mercury blocks the degradation pathway of catecholamines, epinephrine excess causes hyperhidrosis (profuse sweating), tachycardia (persistently faster-than-normal heart beat), mercurial ptyalism (hypersalivation) and hypertension (high blood pressure).
  • Mercury poisoning is caused by sufficient exposure to elemental mercury or mercury compounds. The consumption of fish is by far the most significant source of ingestion-related mercury exposure in humans, although plants and livestock also contain mercury due to bioaccumulation of mercury from soil, water and atmosphere, and due to biomagnification by ingesting other mercury-containing organisms.[3] Exposure to mercury can occur from breathing contaminated air,[4] or from improper use or disposal of mercury and mercury-containing objects, for example, after spills of elemental mercury or improper disposal of fluorescent light bulbs.[5]

  • A 1987 report described a 23-month-old toddler who suffered anorexia, weight loss, irritability, profuse sweating, and peeling and redness of fingers and toes. This case of acrodynia was traced to exposure of mercury from a carton of 8-foot fluorescent light bulbs that had broken in a potting shed adjacent to the main nursery. The glass was cleaned up and discarded, but the child often used the area for play.

Some Comfort About Broken CFLs - Science News - 0 views

  • one of those highly efficient CFLs I’d installed all over the house. She didn’t shatter the whole bulb, just a roughly 3-inch segment of the swirly glass, which (naturally) embedded in the fibers of her carpet. Having heard me warn endlessly of how we should be careful in handling these bulbs — since they contain mercury — she wanted to know what kind of damage control was called for. I only wish I knew then what I do now. It wouldn’t have changed how we cleaned up the mess, but we would have slept a bit better that night.
  • New data from Yadong Li and Li Jin of Jackson State University in Mississippi help put concerns about mercury from broken bulbs in perspective. They measured the mercury present in both new and used CFLs and recorded the continuous emissions from ones that they intentionally broke.
  • Keep in mind, Li notes, a CFL's elemental mercury is not in vapor form unless the lamp is on with a current running through it. Otherwise, the mercury resides along the inside of the glass. And it's from there that the mercury will slowly volatilize once exposed to air. So another lesson: Breaking a CFL while it's turned on can initially disperse a bigger puff of mercury vapor into the air than if its glass is damaged while the bulb is off, Li says
  • ...10 more annotations...
  • A more disturbing finding was how long a broken CFL can continue to release toxic vapors: a minimum of 43 days (which is how long Li and Jin ran their tests with bulbs from three different manufacturers). The engineers computed how much of each bulb’s starting mercury had been lost during that time (which wasn’t easy, since starting values and release rates both varied broadly between bulbs). Their calculations indicate that each CFL still contained enough residual elemental mercury at the end of their testing to continue releasing the toxic substance into the air for at least 10 more days, and in one instance, for 85 more days
  • If not cleaned up, the bulb with the largest initial store of mercury could have spewed 1 milligram of the toxic metal into a room's air within 25 days; another could have reached that level within about 40 days. Li and Jin cited data by others indicating that the release of 1 milligram of mercury vapor into a 500 cubic meter room can yield air concentrations 10 times the current recommended limit for a child. Breaking a CFL can thus cause

  • These steps include airing out the room, putting all debris and cleaning materials into a sealed jar or double plastic bag, and avoiding the use of brooms or vacuum cleaners that might stir mercury into the air.
  • Protection website recommends disposing of the carpet, rug or bedspread on which a CFL breaks. It also suggests that CFLs might not be appropriate in rooms used by infants, small children or pregnant women, who are more susceptible to mercury poisoning.
  • Many hardware stores and local disposal sites accept CFLs for recycling, and some companies now sell pre-paid shipping boxes addressed to recycling plants. Unfortunately, not everyone has easy access to these options, so about three out of four CFLs end up in landfills, where the mercury gets leached into the soil and groundwater.

  • Sealed within the glass tubing of CFLs, is a very small amount of mercury. On average, CFLs contain four milligrams of mercury – about the same amount that would fit on the tip of a ballpoint pen. This may seem high to some, but keep in mind that old thermometers contained about 500 milligrams of mercury. Mercury  allows the bulb to be an efficient light source. No mercury is released when the bulbs are intact or not being used.
  • Thanks to a commitment from members of the National Electrical Manufacturers Association (NEMA), most makers of light bulbs have reduced mercury in their products
  • This has been made easier by advances in technology. Based on these two factors, the average mercury content in CFLs dropped at least 20 percent in the past few years. Some manufacturers have gone as far to have dropped their CFLs’ mercury content to 1.4 to 2.5 milligrams per light bulb.

Fluorescent Lights' Mercury Poses Dim Threat - 0 views

      energy saving but deadly
  • They're breakable, contain toxic material, and are becoming increasingly commonplace. But fears of mercury poisoning from new energy-efficient fluorescent bulbs are overplayed, experts say.
  • But CFLs' cool-burning illumination is made possible by a pinch of poison—about five milligrams of mercury sealed inside every glass tube—and the need for the element is unlikely to change anytime soon. Mercury is a potent neurotoxin and long-lived environmental contaminant, and even the small amount present in CFLs poses a problem. When the bulbs break, either in the house or at a waste disposal site, their mercury content is released. According to a few vocal CFL opponents, such as Fox News Web site's "Junk Science" correspondent

  • These critics have charged environmentalists with being uncharacteristically "pro-mercury" when it comes to the lights. The critics often cite the recent story of a resident of Ellsworth, Maine, who amassed a clean-up bill of more than 2,000 U.S. dollars by shattering a single CFL in her home. The story originally appeared in the Ellsworth American and quickly spread to other newspapers, such as Canada's National Post and the Washington Times.
  • But the enormous bill came about as a result of bad advice—a fact often omitted in follow-ups to the original article. "There's a lot of misleading information out there," said Joel Hogue, president of Elemental Services and Consulting, an Ohio-based company specializing in the cleanup of sites contaminated with mercury. "But when people learn the facts
  • dies down."
  • Like with many other household products, Hogue said, the use of CFLs requires some commonsense precautions. But if a bulb breaks, his company's clean-up services are not required.
  • There's an extremely small amount of mercury in those bulbs," Hogue said. "It's a very minimal risk" and can easily be cleaned up at home. One CFL contains a hundred times less mercury than is found in a single dental amalgam filling or old-style glass thermometer, according to the U.S. Environmental Protection Agency (EPA).
  • Long billed as a "green" product for environmentally conscious consumers, compact fluorescent light bulbs (CFLs) are quickly becoming the norm in household lighting—and may soon replace traditional incandescent bulbs altogether.

Never use vacuum cleaners or brooms.
  • Consumers – especially those with young children –need to know what to do when a CFL breaks and the proper way to dispose of used bulbs. It’s no longer as easy as changing a light bulb
  • If practical, continue to air out the room where the bulb was broken and leave the heating/air conditioning system shut off for several hours.http://www.epa.gov/cfl/cflcleanup.html
  • All of this needs to be done to protect people from the tiny amount of mercury in one fluorescent light bulb. Which begs the question, are these lights really safe and are the risks worth it? Another equally important concern is what happens to the environment – the air, soil and water – when tons of discarded bulbs, along with the mercury, are dumped into local landfills?
  • The threat posed by billions of broken CFLs lying in landfills has resulted in some communities requiring their citizens to discard used and broken CFLs in designated recycling centers or in a hazardous-waste collection facility.
  • Given the known deleterious effects caused by mercury, it would seem logical to assume there will be some unintended consequences resulting from the switch to compact fluorescent lights. Only time will tell how significant those consequences will be.
  • If you are concerned about the possible health risks associated with CFLs, LED or halogen lights are good alternatives. Both cost a little more but are as efficient as CFLs and can be recycled easily. For more information about mercury and compact fluorescent light bulbs go tohttp://www.epa.gov/cfl/

  • Compact fluorescent light bulbs, long touted by environmentalists as a more efficient and longer-lasting alternative to the incandescent bulbs that have lighted homes for more than a century, are running into resistance from waste industry officials and some environmental scientists, who warn that the bulbs’ poisonous innards pose a bigger threat to health and the environment than previously thought.
  • Fluorescents — the squiggly, coiled bulbs that generate light by heating gases in a glass tube — are generally considered to use more than 50 percent less energy and to last several times longer than incandescent bulbs

  • Break a bulb? Five steps for cleanup That was the wrong answer, according to the EPA. It offers a detailed, 11-step procedure you should follow: Air out the room for a quarter of an hour. Wear gloves. Double-bag the refuse. Use duct tape to lift the residue from a carpet. Don’t use a vacuum cleaner, as that will only spread the problem. The next time you vacuum the area, immediately dispose of the vacuum bag.
  • In general, however, the EPA endorses the use of fluorescent bulbs, citing their energy savings. Silbergeld also does not discourage their use because of their energy savings, but she said the EPA could be sending mixed signals to confused consumers.
  • “It’s kind of ironic that on the one hand, the agency is saying, ‘Don’t worry, it’s a very small amount of mercury.’ Then they have a whole page of [instructions] how to handle the situation if you break one,” she
  • “I think there’s going to be hundreds of millions of [CFLs] in landfills all over the country,” said Leonard Worth, head of Fluorecycle Inc. of Ingleside, Ill., a certified facility. Once in a landfill, bulbs are likely to shatter even if they’re packaged properly, said the Solid Waste Association of North America. From there, mercury can leach into soil and groundwater and its vapors can spread through the air, potentially exposing workers to toxic levels of the poison.

Will a Broken CFL Bulb Kill Me? - Planet Green - 3 views

  • The main concern with CFLs is that they contain mercury, a toxic metal, sealed within its glass tubing. Mercury could lead to sickness if you come in direct contact with enough of the substance. But if you didn’t feel sick or aren’t sick now, it’s probably a good chance you are fine, especially since CFLs only contain a small amount

Compact Fluorescent Light Bulb Mercury Warning - 1 views

  • What to Do if a Fluorescent Light Bulb Breaks Fluorescent light bulbs contain a very small amount of mercury sealed within the glass tubing. EPA recommends the following clean-up and disposal guidelines: Open a window and leave the room (restrict access) for at least 15 minutes
  • Remove all materials you can without using a vacuum cleaner. Wear disposable rubber gloves, if available (do not use your bare hands). Carefully scoop up the fragments and powder with stiff paper or cardboard. Wipe the area clean with a damp paper towel or disposable wet wipe. Sticky tape (such as duct tape) can be used to pick up small pieces and powder
  • Place all cleanup materials in a plastic bag and seal it. If your state permits you to put used or broken fluorescent light bulbs in the garbage, seal the bulb in two plastic bags and put into the outside trash (if no other disposal or recycling options are available).

The Problems with Compact Fluorescent (CFL) Bulbs - 0 views

  • Mercury content Like all fluorescent lamps, CFLs contain a small amount of vaporized mercury. Mercury is poisonous even in small amounts. If a bulb is broken, then there is the risk being exposed to dangerous mercury vapors. Though the bulbs are meant to be recycled, many are almost certain to end up in landfills and dumps – polluting the grounds, air, and water with small amounts of the poisonous substance
  • CFL bulbs are often hailed as the green replacement of the older incandescent bulbs. CFLs use less energy and can have a lifespan of around ten times that of incandescents if not turned on and off repeatedly over short periods of time. These are all well and good, but there are some drawbacks to the CFLs that people should know about before making the switch
