Reactive airways dysfunction syndrome following exposure to a fluorocarbon. (1/5)

This report describes the case of a 43-yr-old male who developed reactive airways dysfunction syndrome after exposure to a high level of bromotrifluoromethane (CF3Br, Halon 1301), a fluorocarbon widely used in automatic fire extinguishing systems. The patient was a previously healthy, nonatopic male, who developed wheezing and intermittent and reversible obstructive ventilatory impairment starting immediately after a large accidental nonfire-related release of CF3Br in a confined space.  (+info)

Reactive airways dysfunction syndrome caused by bromochlorodifluoromethane from fire extinguishers. (2/5)

Although the neurological and cardiovascular effects of Freons have been extensively described, the respiratory effects have been less well documented. We report four cases of occupational asthma following accidental exposure to bromochlorodifluoromethane (Halon 1211) due to release of the contents of a fire extinguisher. All subjects developed an irritative reaction of the upper airways and lower respiratory symptoms immediately after exposure. Non-specific bronchial hyperreactivity was present for at least two months in all subjects and was still present more than two years after exposure in one case. The diagnosis of reactive airways dysfunction syndrome can be adopted in at least three of these four cases.  (+info)

A possible mechanism of halocarbon-induced cardiac sensitization arrhythmias. (3/5)

Cardiac sensitization is the term used for malignant ventricular arrhythmias associated with exposure to inhaled halocarbons in the presence of catecholamines. We investigated the electrophysiological changes associated with cardiomyocyte exposure to epinephrine and a halocarbon known to be associated with cardiac sensitization (halon 1301, CF3Br). Cardiomyocytes (CMs) were isolated from neonatal rats and grown on multielectrode arrays (MEAs). Upon exposure to epinephrine, the CM inter-spike interval (ISI) was decreased 14% at 10 microg/L (P<0.05) and 27% at 100 microg/L (P<0.05) as compared to baseline. Halon alone (50 mg/L) mildly prolonged the field potential (FP) duration (7%). CMs exposed to combinations of epinephrine (100 microg/L) and halon (50 mg/L) for 15 min showed a blunted increase in the ISI (35+/-12%) and a 38% decrease in conduction velocity (P<0.05) when compared to epinephrine alone. There was no change in field potential properties, but dephosphorylated connexin 43 (Cx43) was increased 60+/-16% with the combination as compared to epinephrine alone (P<0.05). Treatment with okadaic acid, a phosphatase inhibitor, prevented the Cx43 dephosphorylation and the reduction in conduction velocity upon exposure to halon and epinephrine. Moreover, the electrophysiological changes induced by epinephrine and halon were indistinguishable from those seen with the gap junction inhibitor heptanol. In conclusion, the combination of a halocarbon and epinephrine results in a unique electrophysiological signature including slow conduction that may explain, in part, the basis for cardiac sensitization. The slowing of conduction is most likely related to changes in the phosphorylation state of Cx43.  (+info)

Grand rounds: outbreak of hematologic abnormalities in a community of people exposed to leakage of fire extinguisher gas. (4/5)

CONTEXT: Although there are ample data on the respiratory effects of exposure to fire extinguisher gas, the potential hematologic effects have not been fully documented. We conducted this study to determine the possible etiologic agent(s) for a decrease in red blood cells among community residents in Taipei, Taiwan, after they were exposed to leakage of mixed fire extinguishants containing bromotrifluoromethane (CF3Br, Halon 1301), bromochlorodifluoromethane (CF2BrCl, Halon 1211), and dichlorodifluoromethane (CCl2F2, CFC-12). CASE PRESENTATION: We studied 117 exposed residents who came into one hospital for physical examinations. We also selected age- and sex-matched referents for comparison from residents who came to the same hospital for health examinations. Nine months after the exposure to mixed fire extinguishants, 91 of the exposed residents came back for a second physical examination. In the first examination of the exposed residents, we found a significant reduction in red blood cell count and hemoglobin and a relationship between dose and response. DISCUSSION: After excluding iron-deficiency anemia, thalassemia, and other possible agents, we suspected that the hematologic effects might have resulted from pyrolytic products of CFC-12 and Halon 1211, which may contain phosgene, among other products. RELEVANCE TO CLINICAL PRACTICE: The acute transient hematologic effects observed in the exposed residents were associated with the incident of leakage of mixed fire-extinguisher gases and were most likely caused by a small amount of pyrolytic products, probably phosgene. Nine months after the exposure, we found a significant improvement in the abnormalities without any specific treatment.  (+info)

Assessment of the reproductive toxicology of bromochlorodifluoromethane (BCF, halon 1211) in the rat. (5/5)

The effect of bromochlorodifluoromethane (BCF) on reproduction in the rat has been investigated in two studies. Pregnant female rats were exposed by inhalation to 1000, 10,000, or 50,000 ppm BCF for six hours a day on days six to 15 of gestation (day of mating = day 0). Exposure to 50,000 ppm BCF caused a reduction in maternal weight gain over the exposure period but there was no evidence of either teratogenicity or embryo/fetotoxicity at any concentration. In a study designed to assess the potential effect of BCF during a complete reproductive cycle male and female rats were exposed to 5000 ppm or 25,000 ppm BCF for six hours a day for five days a week for 10 weeks (males) or three weeks (females) before mating. Exposure to BCF continued during mating and up to day 20 of gestation for half the females which were subsequently allowed to litter and the development of their offspring monitored. The remaining females were removed from exposure to BCF after mating and killed on day 20 of gestation for examination of their uterine contents. There were no effects on adult fertility, pup numbers, survival, or pup development. It was concluded that BCF had no reproductive toxicity potential in the rat.  (+info)

If a fire broke out in your home or place of business today, would you automatically know which fire extinguisher to use? What would happen if you used a Class A fire extinguisher on a fire in the electrical service panel in your basement? Answer: youd possibly be electrocuted if the extinguishing agent is a liquid! A long time ago, the fire protection industry recognized the need to classify extinguishers according to the many kinds of burning materials encountered in a fire. For example, Class A, water-type fire extinguishers cannot be used on the electrical fires because the extinguisher operator could be seriously injured by the conduction of electricity by the stream of water from their extinguisher. Instead, a Class C fire extinguisher will work best. Another example, a raging fire in a manufacturing plant with flammable metals, such as magnesium, should be fought with a Class D fire extinguisher (see chart below). Fire Classifications ...

Commonly referred to as "Fast Flow" or "High Performance" extinguishers. Available in 13.2 lb (6.0 kg)., 20 lb (9.1 kg)., and 30 lb (14 kg). capacities and contain ABC Dry Chemical, Purple-K, or sodium bicarbonate. They are currently manufactured by Ansul in cartridge-operated form, along with Amerex, Badger and Buckeye stored pressure design. These extinguishers have a higher dry chemical flow rate then conventional extinguishers. In other words a fast flow extinguisher expels a higher volume of agent in less time than a standard compliance flow extinguisher. As a result fast flow extinguishers have lower UL class A&B ratings than compliance flow extinguishers(the class B numerical rating is the approximate square feet of burning fuel a novice operator could expect to extinguish). UL Class B tests are conducted on fuel in depth fires in what is known as a burn pan. Burn pans come in various sizes (square feet) in relation to what UL rating an extinguisher will receive for successfully ...

Are they fully charged, strategically located, accessible, and ready for use? Or, are they covered with dust and hidden in a corner where they create a false sense of security?. Fire extinguishers are often purchased with enthusiasm and then forgotten because they are not needed. It is a good thing that they have not been needed, but they still need proper inspection and maintenance. Not only is this a legal requirement, but ensures they are ready to use if needed! Remember, fire extinguishers are a first line of defense against fire. Fire extinguishers must be kept accessible and functional to eliminate lost time when they are needed. Inspect your extinguishers monthly to be certain they are charged and in ready to use condition. Annual maintenance inspections are required in accordance with NFPA 10. Other maintenance and inspection requirements are required based on the type of extinguisher. Check the manufacturer owners manual for these requirements.. Also, if staff will be expected to use ...

Vitamins C and E, zinc, selenium, and flavonoid-rich extracts-such as grape seed or pine bark extract (Pycnogenol)-are the most important antioxidants for fighting inflammation. Supplementation with fish oil products that provide a combined dosage of 3 grams EPA+DHA daily has also proved to be effective in reducing inflammation and producing positive changes in numerous trials.. Preparations of proteolytic enzymes-including chymotrypsin, trypsin, bromelain, papain, fungal proteases, and Serratia peptidase-have been shown to be useful in a wide range of inflammatory situations. Look for products that contain a combination, and follow label instructions. You can also find Serratia peptidase as a stand-alone product for inflammation.. MicroLactin, a special milk protein, is gaining recognition as a natural treatment for joint inflammation. During the inflammatory response, the "junctions" between cells that line the joint spaces increase, which allows white blood cells to enter the joint. Once ...
Have plenty of water available to fight fires. An accessible pond or water holding tank will augment available water from your well and tank trucks.. Many fires cannot be classified strictly as one type. They may involve a variety of flammable materials. For this reason, multirated extinguishers have been developed.. Owing to the variety of work conditions that exist on the farm, farmers are advised to use an all-purpose, ABC rated extinguisher. This extinguisher uses a dry chemical agent and is capable of extinguishing Class A, B or C fires. The extinguisher is available in a variety of sizes and is not susceptible to temperature extremes. All portable extinguishing equipment should be strategically located on the farm and checked regularly. Everyone on the farm should be trained in the safe us of extinguishers.. For many years, carbon tetrachloride (CC14) was a common type of extinguishing agent. Research has shown that CC14 is not a safe extinguishing agent because when it comes in contact ...
After taking several minutes to perform his walk-around check, the tall, lanky man returned to the flight lounge to ask if anyone would be available to stand by with fire extinguishers while he "flashed the old bird up, just to be safe." Though only 12 at the time I was allowed to stand by with an extinguisher after brief instruction on its use -- "If you see a fire, point, then pull this lever!", he said. (I later became a firefighter, but thats another story.) The air around the exhaust manifolds shimmered like a mirror from fuel fumes as the huge prop started to rotate. One manifold, then another, and yet another barked -- I stepped back with the others. In moments the Packard-built Merlin engine came to life with a thunderous roar. Blue flames knifed from her manifolds with an arrogant snarl. I looked at the others faces; there was no concern. I lowered the bell of my extinguisher. One of the guys signaled to walk back to the lounge. We did ...
Ansuls high-flow extinguishers are equipped with a special nozzle and nozzle tip to maximize agent flow rates. The nozzle handle is painted red to differentiate it from standard flow extinguishers.. Note: High flow extinguishers are designed for pressurized flammable liquids and pressurized gas fires and other special hazards where agent flow rate is crucial to extinguishment. (Reference NFPA 10, Paragraph 2-3.1 and 2-3.3.) The high flow extinguishers can also extinguish other type of fires but the shorter discharge times versus standard extinguisherss reduces the effectiveness of novice fire fighters. So choose carefully and be sure to train potential users!. ...

Our second installment for Safety Awareness Month is a yearly checklist for sprucing the safety of your home (for you and your baby). Think spring cleaning sans the dusting.. 1. Change the batteries in your smoke detector. Also, check your fire extinguisher to make sure its not expired (they really can expire!) Even if its not expired, get it inspected once a year by a professional. Contact your local fire department or check the yellow pages under fire extinguisher.. 2. Consider investing in a carbon monoxide detector. Babies and pregnant women are most vulnerable to carbon monoxide poisoning, and its good to have one in homes with gas stoves, a fireplace, central heating systems and/or gas water heaters.. 3. Clean out your medicine cabinet and throw away expired medications. The ones you keep should stay locked out of reach of crawling tots.. 4. Update your emergency contacts and post them somewhere visible. Make sure your list includes poison control, your family doctor, a local ...
See the file - Baking Soda Volcano for the chemistry behind the above reaction. Note that the reaction produces carbon dioxide gas (CO2). Unlike oxygen gas (O2), CO2 is not readily combusted by the flame. It is also *heavier* than the other gasses which make up our atmosphere. Nitrogen gas (N2 - ~75% of the atmosphere) has an atomic weight of 30; O2 - a weight of 32 (~20% of air). CO2 has a weight of 44 (C = 12 a.m.u + (2 O = 2X16 a.m.u) = 44). It thus *sinks* to the bottom of your jar when evolved from the vinegar/baking soda mixture. If enough is created, it will reach the level of the flame. When the candle can no longer continue combusting its material with oxygen, it goes out. Incidentally, for this reason, many fire extinguishers use compressed CO2 to put out fires. By filling the space around the fire with CO2, you essentially suffocate the fire. Unfortunately since we need oxygen gas to survive, breathing pure CO2 also suffocates us. ...
The story is this. A young family from Half Moon Bay was traveling south through Kern County on Highway 99 at about 3:15 pm when they got a flat tire just north of Highway 119. Driver Juan Rodriquez slowed to a stop in the center median divider, turned on his hazard signal, and got out of his 2002 Jeep to change the tire. Remaining in the car were his wife Karla and their children Zoey 3, and Emiliano, 5.. A 2017 Chevrolet speeding south, with an allegedly drunk driver at the wheel, drifted into the center median striking Juans parked Jeep. We can only imagine Juans horror as the Jeep holding his family was struck and slammed forward, ending up on its side on the center divider with his wife and children trapped inside. The Jeep then caught fire. Kind motorists stopped and rushed over with fire extinguishers to put out the fire and managed to remove Karla and the children from the burning vehicle.. Karla and Zoe were rushed to the hospital, but little Emiliano died at the scene. Kern Medical ...

One possible area of research may be with old fire fighting apparatus. The item is about the right size and shape for an early form of self-activating fire extinguisher - the bands supported an upside down tear-drop shaped glass globe filled with liquid. A trip-band of low-melting point babbit or wax restrained a spring fed plunger that extended through the hole in the bottom that, when released, fractured the glass globe, releasing the liquid. The cone that formed the bottom of the item was supposed to disperse the liquid over a broader area. There was also a small mallet or glass breaking bar that hung from a ring on the side that could be used to manually break the globe ...

In a gun fight in the hearing room the younger generation that would see Bond and the old M kindly on their way into some dignified retirement are all attempting to make killshots on Silva, who has come into to kill M for what he believes was her treachery toward him. As people like Mallory and the field agent who will turn out to be the famous desk agent Eve Moneypenny attempt to shoot to kill and fail Bond pulls out his gun. He shoots to confuse, using his famous Walther PPK to saturate the courtroom with fire retardants from the fire extinguishers in the room. Silva ends up being thwarted, of course, not by the youngsters who have said there are no shadows anymore and that M should step down, but by the man who is considered physically, mentally, and emotionally unfit to be in the fight, our dear old James Bond. As Q put it, eventually someone has to pull a trigger and Bonds reticence about his work is how often and why a trigger has to be pulled. Having been shown unable to make easy shots ...
2) OXO Candela Luau Portable Lamp: While many of us has different versions of what a portable lamp comes to mind, be it a hybrid radio/ lamp/flash light or a mere table top lamp, one should have at least this device to endure in lengthy hours of power interval. One thing that comes close to mind is the Oxooutdoor lantern that can light up your life up to 10hours, depending on the brightness setting. If your TVs out and DVD marathons not possible, then better grab this portable lamp and just commune with good books.. 3) Candles: But if you dont have $199 to boot for a portable lamp, then better get candles but youve got to be careful since it is one of the firemans hot list on the most common causes of fire. The most nifty design I have come across with is this beer-inspired candle. Now, if youre thinking of pleasuring your alcohol-drenched friends with Christmas presence, this might be the IT thing.. 4) Emergency Light: Known to be as common office must-haves as with fire extinguisher, ...

However, some people will use candles because its all they have, or because they run out of batteries for flashlights. If you do use candles, use ones in a sturdy jar with a lid because they are less prone to being knocked over. Be sure they are carefully supervised and never leave the room if a candle is burning! Dont put them close to anything burnable (like blowing curtains), and place them on a non-burnable surface just in case they get bumped. Dont forget the need for a dependable way to light them (matches or lighters, stored out of the reach of children), and have a fire extinguisher nearby, just in case something does catch ...
Federal regulators have found numerous safety violations on the states troubled commuter rail system, including the lack of on-board emergency tools and working fire extinguishers, trains stopping too close to each other and workers using cellphones when they shouldnt have.
A rubbish container with automatic compressing mechanism mainly including a housing, a plurality of rubbish bins positioned inside the housing to collect sorted rubbish, movement control channels provided in the housing to support a transversely extended top board, and an automatic compressing mechanism mounted on the top board. A motor is connected to one end of one of the movement control channels to rotate a threaded rod therein, so that the top board connected to the threaded rod and the compressing mechanism on the top board are brought to translate along the movement control channels to and fro in the housing over the rubbish bins. The compressing mechanism has a motor to drive a compressing member and a compressing plate connected to a lower end of the compressing member to move up and down, compressing rubbish collected in the rubbish bins to a reduced volume. Fire extinguisher and deodorizing units can be provided in the housing to permit the
Why does it afflict people so differently? My father and I both expect to see the Grim Reaper pointing his bony finger of damnation at us when we get a cold. Stipulating that Im giant baby about these things, its nonetheless true that everytime I get a cold I feel like I spent the night in a Bolivian jockey bar drinking tequilla-and-sewer water and fighting-off a dozen little dudes who eventually beat me about the head and chest with fire extinguishers. Meanwhile, the missus - of hardy Alaskan stock, to be sure - can function at about 50% efficiency. Do certain ethnic groups suffer more than others? Is it partly a male-female thing? It vexes me ...

Commonly referred to as "Fast Flow" or "High Performance" extinguishers. Available in 13.2 lb (6.0 kg)., 20 lb (9.1 kg)., and 30 lb (14 kg). capacities and contain ABC Dry Chemical, Purple-K, or sodium bicarbonate. They are currently manufactured by Ansul in cartridge-operated form, along with Amerex, Badger and Buckeye stored pressure design. These extinguishers have a higher dry chemical flow rate then conventional extinguishers. In other words a fast flow extinguisher expels a higher volume of agent in less time than a standard compliance flow extinguisher. As a result fast flow extinguishers have lower UL class A&B ratings than compliance flow extinguishers(the class B numerical rating is the approximate square feet of burning fuel a novice operator could expect to extinguish). UL Class B tests are conducted on fuel in depth fires in what is known as a burn pan. Burn pans come in various sizes (square feet) in relation to what UL rating an extinguisher will receive for successfully ...
Sensitizer-induced occupational asthma immunologic form of asthma which occurs due to inhalation of specific substances (i.e., high-molecular-weight proteins from plants and animal origins, or low-molecular-weight agents that include chemicals, metals and wood dusts) and occurs after a latency period of several weeks to years.[1]. Irritant-induced (occupational) asthma is a non-immunologic form of asthma that results from a single or multiple high dose exposure to irritant products. It is usually develops early after exposure; however can also develop insidiously over a few months after a massive exposure to a complex mixture of alkaline dust and combustion products, as shown in the World Trade Center disaster. Unlike those with sensitizer-induced occupational asthma, subjects with irritant-induced occupational asthma do not develop work-related asthma symptoms after re-exposure to low concentrations of the irritant that initiated the symptoms.[2] Reactive airways dysfunction syndrome (RADS) is ...
... is also used as a relatively strong base in various fields. As a common alkali, it is preferred in many chemical processes because it is cheaper than NaOH and far safer to handle. Its mildness especially recommends its use in domestic applications. For example, it is used as a pH regulator to maintain stable alkaline conditions necessary for the action of the majority of photographic film developing agents. For example, it is a common additive in swimming pools and aquarium water to maintain a desired pH and carbonate hardness (KH). In dyeing with fiber-reactive dyes, sodium carbonate (often under a name such as soda ash fixative or soda ash activator) is used to ensure proper chemical bonding of the dye with cellulose (plant) fibers, typically before dyeing (for tie dyes), mixed with the dye (for dye painting), or after dyeing (for immersion dyeing). Sodium bicarbonate (NaHCO3) or baking soda, also a component in fire extinguishers, is often generated from sodium carbonate. ...
... -Hanckwitz FRS (1660 - 15 January 1741), also known as Gottfried Hankwitz, also written Hanckewitz, or Ambrose Godfrey as he preferred to be known, was a German-born British phosphorus manufacturer and apothecary. He was one of the first phosphorus manufacturers and was one of the best and most successful in his time. He invented and patented a machine that acted as a fire extinguisher. Godfrey was born in Nienburg in Saxony. In 1679, aged 19, he and his wife travelled to London where he was to work as an assistant to Robert Boyle, trying to produce phosphorus. Boyle is remembered as the first chemist, but his earliest interests were in alchemy, and he wanted to learn about the then new phosphorus. Boyle had employed German alchemist Johann Becher who was in London looking for work. Becher recommended Ambrose Godfrey as an assistant. Boyle knew from hints given by Daniel Kraft (when he had demonstrated phosphorus) that it was made from human urine or maybe faeces, but neither ...
... (ADP), also and better known as monoammonium phosphate (MAP) in order not to confuse it with adenosine diphosphate (ADP), with formula NH4H2PO4, is formed when a solution of phosphoric acid is added to ammonia until the solution is distinctly acidic. It crystallizes in tetragonal prisms. Monoammonium phosphate is often used in the blending of dry agricultural fertilizers. It supplies soil with the elements nitrogen and phosphorus in a form usable by plants. The compound is also a component of the ABC powder in some dry chemical fire extinguishers. This substance is also supplied in an emerald green, amethyst, aquamarine and any other color available, crystal growing box kit for children. Solid monoammonium phosphate shows a dissociation pressure of ammonia of 0.05 mm Hg at 125 °C based on the decomposition reaction as follows: NH4H2PO4(s) ⇌ NH3(g) + H3PO4(l) ADP is a widely used crystal in the field of optics due to its birefringence properties. As a result of ...
In 1961, President John F. Kennedy accepted a modified, dark blue, 1961 Lincoln Continental that cost almost US$200,000 (equivalent to $1,676,837 in 2018). Assigned the Secret Service code name of X-100, it was the most sophisticated presidential state car yet built. The car included a "heavy-duty heater and air conditioner, a pair of radiotelephones, a fire extinguisher, a first-aid kit, and a siren." The exterior featured improved, retractable standing platforms and handles for Secret Service agents, and flashing red lights recessed into the bumper. Unique to the X-100 were three sets of removable roofs (a standard soft top, a lightweight metal one, and a transparent plastic one) and a hydraulic lift that raised the rear cushion 10 1⁄2 inches (270 mm) off the floor. Both of these feature sets were designed to make the president more visible to the public. Unfortunately, they were also contributors in the assassination of John F. Kennedy. After the Kennedy assassination, the X-100 was ...
The uses of carbon tetrachloride have diminished lately because it is known to be damage people's health. People think it might damage the ozone layer. Today, it is rarely used for anything.. Previously, was used in fire extinguishers. It was also used to make freon, used in dry cleaning and as a refrigerant.. ...
The details of polar ozone hole formation differ from that of mid-latitude thinning, but the most important process in both is catalytic destruction of ozone by atomic halogens.[1] The main source of these halogen atoms in the stratosphere is photodissociation of man-made halocarbon refrigerants (CFCs, freons, halons.) These compounds are transported into the stratosphere after being emitted at the surface.[2] Both types of ozone depletion were observed to increase as emissions of Halocarbons increased. CFCs and other substances contributing to this effect are referred to as ozone-depleting substances (ODS). Since the ozone layer prevents most harmful UVB wavelengths (280-315 nm) of ultraviolet light (UV light) from passing through the Earth's atmosphere, observed and projected decreases in ozone have generated worldwide concern. As a result, the Montreal Protocol has been adopted. The treaty bans the production of CFCs, halons as and other ozone-depleting chemicals such as carbon tetrachloride ...
The PhostrEx fire suppression system addresses many of the problems with halon, from system weight to environmental concerns. These concerns, including halon's ozone-depleting and global warming characteristics, prompted the Montreal Protocol to outlaw its use. The only exception allowed by this international treaty was in aviation applications, and only until a suitable replacement became available. PhostrEx meets the requirements of both the Montreal Protocol and the Clean Air Act, and is the first commercially viable Federal Aviation Authority and United States Environmental Protection Agency certified halon replacement fire extinguishing agent. The EPA awarded the company with a 2007 Stratospheric Ozone Protection Award for the development of its PhostrEx fire-suppression system.[2] PhostrEx reacts very quickly with atmospheric moisture, breaking down into phosphorus acid and hydrogen bromide. Neither of these harms the ozone layer. High concentrations of PhostrEx can cause skin blistering ...
... is the fourth generation of a series of NASA Earth-observing instruments, known as the Stratospheric Aerosol and Gas Experiment. The first SAGE III instrument was launched on the Russian Meteor (satellite) spacecraft. The recently revised SAGE III will be mounted to the International Space Station where it will use the unique vantage point of ISS to make long-term measurements of ozone, aerosols, water vapor, and other gases in Earth's atmosphere. The first SAGE instrument was launched February 18, 1979, to collect data on the various gases in the atmosphere, including ozone. The data collected on SAGE I and the following instrument SAGE II, which began taking measurements in October 1984, were critical to the discovery of the Earth's ozone hole and the creation of 1987 Montreal Protocol, which banned ozone-depleting substances, such as chlorofluorocarbon (CFC). SAGE III on ISS is a nearly exact replica of SAGE III Meteor-3M, sent into orbit in 2001 on a Russian satellite. SAGE ...

The haloalkanes (also known as halogenoalkanes or alkyl halides) are a group of chemical compounds derived from alkanes containing one or more halogens. They are a subset of the general class of halocarbons, although the distinction is not often made. Haloalkanes are widely used commercially and, consequently, are known under many chemical and commercial names. They are used as flame retardants, fire extinguishants, refrigerants, propellants, solvents, and pharmaceuticals. Subsequent to the widespread use in commerce, many halocarbons have also been shown to be serious pollutants and toxins. For example, the chlorofluorocarbons have been shown to lead to ozone depletion. Methyl bromide is a controversial fumigant. Only haloalkanes which contain chlorine, bromine, and iodine are a threat to the ozone layer, but fluorinated volatile haloalkanes in theory may have activity as greenhouse gases. Methyl iodide, a naturally occurring substance, however, does not have ozone-depleting properties and the ...
R-11 is assigned an ozone depletion potential of 1.0, and U.S. production was ended on January 1, 1996. Prior to the knowledge of the ozone depletion potential of chlorine in refrigerants and other possible harmful effects on the environment, trichlorofluoromethane was sometimes used as a cleaning/rinsing agent for low-pressure systems.[4] Trichlorofluoromethane was formerly used in the drinking bird novelty, largely because it has a boiling point of 23.77℃ (74.79℉). The replacement, dichloromethane, boiling point 39.6℃ (103.3℉), requires a higher ambient temperature to work. The substance was included in the production moratorium agreed in the Montreal Protocol of 1987. However, in 2018, its atmospheric concentration was noted to be declining more slowly than expected,[5] and it subsequently emerged that it remains in widespread use as a blowing agent for polyurethane foam insulation in the construction industry of China.[6] ...
