In order to have a better understanding of actual emissions the Environmental Protection Agency is looking to find a better way to receive data that is accurate. Lastly, you can write letters to government agencies and officials and businesses asking for them to reduce or discontinue the use of fluorinated gases in consumer products. Note: This article is republished from The Conversation under a Creative Commons license. Understand that gross emissions are OVER 25,000 mtCO2e and therefore report under part 98. The sheer amount of SF6 used in the medium-voltage (MV) and high-voltage (HV) sectors nevertheless raises environmental concerns. See more on the confidentiality issue here. Subscribe to feeds for updates on EIA products including Today in Energy and What's New. It contributes between 10-25% of global warming and though it remains in the atmosphere for less time than CO2 does (about 10 years vs. 100), methane eventually turns into more CO2. . Energy & Financial Markets: What Drives Crude Oil Prices? Come test out some of the products still in development and let us know what you think! Due to its extreme global warming potential, the California Air Resources Board (CARB) passed a regulation restricting Sulfur Hexafluoride (SF6) gas emissions, pursuant to the California Global Warning Solutions Act of 2006. Carbon dioxide (CO2) is a gas that is naturally-occurring and generated by human and animal respiration that is made of one carbon atom and two oxygen atoms. Sulfur Hexaflouride Possession of Purchases. The chart above shows the relative impact of six greenhouse gases. But leaks of the little-known gas in the UK and the rest of the EU in 2017 were. The EPA is becoming increasingly concerned with the inaccuracies they are finding in their reports around sulfur hexafluoride inventory and emissions, especially since SF6 is such a potent greenhouse gas. So what does the EPA mean by this? In the production of magnesium and magnesium parts, SF(i is used to prevent rapid oxidation of the metal from exposure to air. When we touched upon sulfur hexafluoride back in 2019 in the context of greenhouse gases, it was noted that most SF 6 is used for and leaks from high-voltage switchgear (mechanical. <> stream Shipped as a liquefied gas under own vapor pressure. Short, timely articles with graphics on energy, facts, issues, and trends. They pose a threat to the atmosphere particularly because they are not a natural component of it. CFCs, sulfur hexafluoride, hydrofluorocarbons (HFCs), and perfluorocarbons are two more trace gases created that have greenhouse effects (PFCs). But, if you are like most people, you probably dont know much about SF6. Ozone is technically a greenhouse gas, but ozone is helpful or harmful depending on where it is found in the earth's atmosphere. Emissions estimates for the high-GWP gases are provided to EIA by the EPA's Office of Air and Radiation. The right amount of CO2 is important so that people, animals, and plants can breathe. You can choose products that do not come in aerosol cans. Though it is found naturally in our atmosphere, fertilizer and fuel combustion are major sources of nitrous oxide overproduction. Twelve U.S. magnesium companies have formed a partnership with the Environmental Protection Agency to reduce emissions of sulfur hexafluoride, said Scott C. Bartos, EPA program manager for the partnership. However, we do not guarantee individual replies due to the high volume of messages. This update is trying to incorporate sources of greenhouse gas emissions overlooked to this point. This rule change updates the emissions factors and calculations for gases used during semiconductor manufacture, including sulfur hexafluoride. It is used in insulation, electric power transmission equipment, in the magnesium industry, in semiconductor manufacturing to create circuitry patterns on silicon wafers, and also as a tracer gas for leak detection. For general feedback, use the public comments section below (please adhere to guidelines). This is because SF 6 is actually the most potent greenhouse gas that has ever been evaluated by the Intergovernmental Panel on Climate Change. Based on the SS-1 equation, electrical equipment manufacturers and refurbishment must track the total annual purchases of insulating gas, as well as understanding the weight fraction of fluorinated GHG in the insulating gas if the insulating gas is a gas mixture, and the GWP for that gas or mixture. empirical study on the environmental and socio-economic impact of SF, control, measuring, protective, and regulating equipment, "which constitutes the backbone of the infrastructure necessary to deliver the energy transition", report reassessing the availability of alternatives to SF in MV switchgear, Sulfur hexafluoride: The truths and myths of this greenhouse gas, Improved internal arc protection with new techniques, Power supply systems for deep sea factories, Hydrogen-based heating could help UK reach net-zero carbon by 2050, Paper-thin solar cell can turn any surface into a power source, Researchers harvest electricity from wood soaking in water, Economical eco-friendly fabrication of high efficiency chalcopyrite solar cells, Creating buildings with an ecological envelope, New battery technology has potential to significantly reduce energy storage costs, Flameproofing lithium-ion batteries with salt, Built to last: Perovskite solar cells tough enough to match mighty silicon, New optical computing approach offers ultrafast processing, DeepMind's AlphaCode attains 'average' rating in programming competition, A 1.3-micrometer-thin elastic conductor for wearable and implantable devices, Electric car sales drive toward cleaner air, less mortality, New facial recognition technology scans your ear, Finding simplicity within complexity: Engineer develops method that can predict behavior, improve weather forecasting, New materials for the computer of the future, An AI app that can spot deepfake videos of famous people, New study unveils generalized optical printing of photocurable metal chalcogenides, A reconfigurable device based on 2D van der Waals heterostructures that works both as a transistor and memory, Scientists shine a light on what comes up when you flush (video).

Sulfur hexafluoride is used to allow certain segments of the heart, liver, or urinary tract to be seen more clearly on an ultrasound examination. This requirement would help to inform the development of GHG policies and programs by providing information on N2O, sulfur hexafluoride, and PFC uses and their relative importance, where the GWP-weighted quantities of these compounds that are supplied annually to the U.S. economy are relatively large, and where the identities and magnitudes of the uses of these compounds are less well understood. For subpart OO, EPA is proposing to require suppliers of nitrous oxide (N2O), saturated PFCs, and SF6 to identify the end uses for which the N2O, SF6, or PFC is used, and the quantities of N2O, SF6, or each PFC transferred to each end use, if known. It has an atmospheric life of 3,200 years and global warming potential 23,900 times stronger than carbon dioxide. Sulfur hexafluoride is reported as a "dry air mole fraction", defined as the number of molecules of sulfur hexafluoride divided by the total number of molecules in the sample, after water vapor has been removed. But, carbon monoxide does not affect the planet's environment directly so it is not considered a greenhouse gas. 2014;48(1):599-606. doi: 10.1021/es403884e. To avoid an input gas emission factor greater than 0.8 when multiple gases are used, the EPA is proposing to introduce an additional calculation method. To answer these questions, we use results from our recent empirical study on the environmental and socio-economic impact of SF6 and its alternatives. atmospheric sulfur hexafluoride: sources, sinks and greenhouse warming. The Conversation, Intervention on a medium-voltage circuit breaker, an electrical switchgear using SF6 gas. Carbon dioxide, methane, and water vapour are the most important greenhouse gases.

U.S. Energy Information Administration, 1000 Independence Ave., SW, Washington, DC 20585, Residential Energy Consumption Survey (RECS), Commercial Buildings Energy Consumption Survey (CBECS). Similar to Subpart I, the revision to Subpart SS sets the reporting threshold for SF6 to 25,000 mtCO2e for electrical equipment manufactures and refurbishment. Subpart SS currently requires facilities that have total annual purchases of SF6 and PFCs that exceed 23,000 pounds to report. It's highly stable, non-toxic, non-flammable and electronegative, which means it will not form other compounds that will alter its state and effectiveness. This sustainable MV equipment uses pure air and vacuum interruption technology instead of sulfur hexafluoride (SF6). The EPA is proposing to require at 40 CFR 98.416(k) that suppliers of N2O, saturated PFCs, and SF6 identify the end uses for which the N2O, SF6, or PFC is used and the aggregated annual quantities of N2O, SF6, or each PFC transferred to each end use, if known. Tools to customize searches, view specific data sets, study detailed documentation, and access time-series data.

How much carbon dioxide is produced when different fuels are burned? Nitrous oxide is responsible for 0.16 watts per square meter. HFO-1336mzz(E), . It is not very water soluble, but does dissolve in organic solvents. Because of its unique dielectric properties, electric utilities rely heavily on SF 6 in electric power systems for voltage electrical insulation, current interruption, and arc quenching in the transmission and distribution of electricity. The data are expressed in CO 2 equivalents and refer to gross direct emissions from human activities. Compared with carbon dioxide, sulfur hexafluoride (SF6) causes 23,500 times as much warming and tetrafluoromethane (PFC-14), which is used as a refrigerant and in electronics, causes 6,630 times as much warming. Sulfur hexafluoride or sulphur hexafluoride ( British spelling) is an inorganic compound with the formula SF 6. Exploration and reserves, storage, imports and exports, production, prices, sales. Some gases occur naturally and are also produced by human activities. In actuality, the emissions factor calculated using these 2 methods can exceed 1. Sulfur hexafluoride (SF 6) is a synthetic fluorinated compound with an extremely stable molecular structure. The European Commission recently publishing a report reassessing the availability of alternatives to SF in MV switchgear. So 1000 cm-1 = 0.001 cm. With a global warming impact that is 23,500 times higher compared to CO2 and an atmospheric lifetime of 3,200 years, SF6 is the most harmful known greenhouse gas. With all of these changes, it is easy to become overwhelmed. And they dont all stay in the atmosphere for the same amount of time.

The chart above shows the relative impact of six greenhouse gases. It is a potent greenhouse gas with a high global warming potential, and its concentration in the earth atmosphere is rapidly increasing. For glass production, the EPA proposes to require facilities to report the annual quantity of glass produced by the facility in tons, by glass type, from each continuous glass melting furnace and from all furnaces combined.. Sulfur hexafluoride is critical to several industries, including electric power systems, where SF6 is used as an arc quenching medium and electrical insulator. Nitrous oxide (NO) causes 265 times as much warming and methane causes 28 times as much warming. Science Team Docs. Therefore, we are proposing to revise the applicability threshold to align with the proposed revisions to require reporting of additional FGHG beyond SF6 and PFCs. We can use fans instead of air conditioners. Specimens of 2024-T6 and 6061-T6 aluminum alloys, cold-rolled AISI C-1020 steel, and annealed AISI type 304 and 316 stainless steels and AISI No. Natural gas, human and animal activity (particularly the digestive habits of cattle), and waste are major sources of methane. Considered cost-effective and high-performing, SF6 technology plays an important role for the reliability of power transmission and distribution networks in Europe, "which constitutes the backbone of the infrastructure necessary to deliver the energy transition". They also seek to add this requirement for cement production to back-estimate reported GHG emissions. And there is also an added requirement that purge flow indicators be calibrated each time a vacuum pump is serviced or exchanged. a source of greenhouse gas emissions from a generator of electricity or a commercial or industrial site, which source may include, but not be limited to, a transportation fleet; . Greenhouse Gases: Sulfur Hexafluoride (SF 6) Flask: Discrete: Multiple: Download: Readme: 50: Mariana Islands, Guam (GMI) Air samples collected in glass flasks. Such a label could for instance feature an evaluation of the product's environmental impact or be used to certify F-gas free switchgear. Our results reveal that switchgear users generally anticipate a decrease in the use of SF6 technology. Several articles are pointing the finger at the growth in renewablesspecifically wind. To describe the Fluorinated gases are human-made gases that are often used in refrigerants, air conditioners, foams, and aerosols, like haircare products or certain cleaning products. Now the EPA is requiring that every company run an emissions calculation (DD-3) to determine their actual emissions from sulfur hexafluoride and PFCs. SF6 also lasts in the atmosphere for more than 3,000 years after it is released. Abstract: We report a 40-year history of SF 6 atmospheric mole fractions measured at the Advanced Global Atmospheric Gases Experiment (AGAGE) monitoring sites, combined with archived air samples, to determine emission estimates from 1978 to 2018. The fact that customers seem to care about environmental aspects when purchasing MV switchgear suggests that an environmental label for MV switchgear could help accelerate adoption of alternative technologies. Adding to its potency is sulfur hexafluoride's atmospheric lifetime of 3,200 years which makes this gas one of the worst atmospheric pollutants on paper. The information you enter will appear in your e-mail message and is not retained by Tech Xplore in any form. We can cut back on the amount of meat that we eat and use more energy-efficient sources for power and transportation. It is the most potent of the six greenhouse gases regulated by the 1997 Kyoto Protocol: one tonne of . For the purposes of this blog we are focusing on the major changes that were made to the following subparts based on relevance and impact: EPA is proposing new thresholds for reporting, a new emissions factor calculation method, and new GHG impact calculations for F-gases used during semiconductor manufacturing. Sulfur hexafluoride: The truths and myths of this greenhouse gas 15 January 2020, by David Nikel Credit: CC0 Public Domain The atmospheric concentration of the highly-potent SF6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. The emission factors calculated using these methods are also expected to be reasonably robust except under certain circumstances discussed further in this section. Sources that will be covered by reporting requirements for the first time include: pneumatic controller venting; abnormal emission events that are unaccounted for with existing reporting requirements (i.e., other large release events such as storage wellhead leaks and well blowouts); and acid gas removal vents. It is used extensively in various electronic components and in the production of magnesium and aluminium. Chart by Our World in Data with data from IPCC (2014). ), it is impossible to prove to the EPA that you do or dont have to report under 98. Fluorinated gases - such as hydrofluorocarbons, perfluorocarbons and sulfur hexafluoride - are GHGs that do not occur naturally. How strong is it? the Science X network is one of the largest online communities for science-minded people. It is inorganic, colorless, odorless, non-flammable, and non-toxic. Greenhouse gases absorb this infrared radiation and trap its heat in the atmosphere, creating a greenhouse effect that results in global warming and climate change. Our study focuses on the MV sector where alternative technologies are more advanced and expected to gain ground faster than in the HV sector. Tech Xplore is a part of Science X network. Typical for a nonpolar gas, SF Most of them are nitrogen and oxygen which have no impact on the climate. Includes hydropower, solar, wind, geothermal, biomass and ethanol. Previously we reported a global emission rate of 7.30.6 Gg yr 1 in 2008 and over the past decade emissions have continued to increase by about . 5. When the EU F-gas regulation was last revised in 2014, it was considered that no cost-effective and reliable alternatives to SF6 were available. However, due to its excellent technical properties, SF6 has been increasingly used as an insulating and switching medium in HV and MV sectors since the 1950s. Some companies are investigating other options, such as building artificial trees to help filter the air. Sulfur hexafluoride, commonly known as SF 6, has made a splash in the mainstream media of late. Many gases exhibit these greenhouse properties. Several major greenhouse gases that result from human activity are included in U.S. and international estimates of greenhouse gas emissions: Other greenhouse gases not counted in U.S. or international greenhouse gas inventories are water vapor and ozone. Reports requested by congress or otherwise deemed important. This is especially the case as ongoing network extensions and the integration of renewable energy installations are increasing the banked SF6 volume. The survey was completed anonymously by a total of 443 respondents in five European countries during November 2019-January 2020. To be widely adopted, SF6-free alternatives must not only meet environmental but also technical and economic requirements. Our software allows organizations of any size to track, monitor, and report their use of the sulfur hexafluoride and its emissions in one simple platform. Which absorption band (s) make SF6 a greenhouse gas? You can select up to five factors. While production volumes for alternatives remain low and prices high, financial incentives for users could spur adoption. . SF6 is one of the worst greenhouse gases in terms of its global warming impact. Fluorinated gases may only account for 3% of greenhouse gas emissions, but they are 23,000 times stronger than CO2. However, a recent change to triggers are reducing the threshold by 90% making many more companies, including semiconductor, electrical distribution, and even glass manufactures responsible for reporting. endobj Luckily, leakage rates are low and accidents extremely rare. Similar to Subpart OO, the EPA is requiring Liquified Gas manufactures and importers to identify the end use for each gas. This is an entirely new industry, so understanding its impact on total carbon emissions is critical to understanding its significance in reducing carbon emissions. Sulfur hexafluoride is 23,500 times more powerful than CO2 as a greenhouse gas. Reprint (Version printed in journal) Authors. The EPA is proposing changes to improve our understanding of end-uses of GHGs and to better understand GHG supply. Sulfur Hexafluoride is a colorless, odorless gas. It gets worse. Schedule a meeting with a Trakref representative today to find out how we can help you on your SF6 compliance journey to lower global emissions of this dangerous gas.

International energy information, including overviews, rankings, data, and analyses. Giving your ESG managers, asset managers, and end users the tools they need to get the job done efficiently. SO x sulfur oxide gases . Asked about policies in general, respondents consider financial incentives (e.g. Besides reducing our use of fossil fuels, we use carbon-negative technology, such as using biochar, a charcoal-like fertilizer that keeps excess carbon underground. All those extra layers could cause you to feel overheated. Comprehensive data summaries, comparisons, analysis, and projections integrated across all energy sources. Methane is a gas that is generated from human and animal activity, as well as from the Earth itself. The Greenhouse Gas Reporting Program (GHGRP) is an EPA program that requires reporting of greenhouse gas (GHG) data and other relevant information from large GHG emission sources, fuel and industrial gas suppliers, and CO2 injection sites in the United States. Document Type. Our Earth is able to maintain its temperature with the right balance of naturally-found greenhouse gases, but when we add too much of them, the heat gets trapped. The Intergovernmental Panel of Climate Change (IPCC) deemed sulfur hexafluoride the world's most powerful greenhouse gas, with the chemical weighing in at a stout 22,200 times more heat. by Marie-Charlotte Guetlein and Carine Sebi These include the fluorinated gases: chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), hydrofluorocarbons (HCFCs), bromofluorocarbons (halons), perfluorcarbons, PFCs, nitrogen trifluoride, NF 3, and sulfur hexafluoride, SF 6. Fluorinated gases: Hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride are synthetic, powerful greenhouse gases that are emitted from a variety of industrial processes. When most people think nitrous oxide, they think of the laughing gas that dentists give their patients before tearing into their teeth. These include hydrofluorocarbons, perfluorocarbons and sulfur hexafluoride . The EPA has pledged to continue using GHGRP data to evaluate potential new regulations for reporting sectors. Logout. Sulfur hexafluoride is used in electrical equipment such as circuit breakers and transformers. Not surprisingly, the Kyoto Protocol lists SF 6 as one of the six greenhouse gases that are restricted for use (together with CO 2, CH 4, N 2 O, HFC and PFC). To quote the EPA: We are proposing to remove the existing nameplate capacity threshold, and instead provide a calculation method for facilities to estimate total annual GHG emissions for comparison to the 25,000 metric tons of CO2 threshold. What can we do about it? Both the all-input gas method and the dominant gas method can provide an emissions factor greater than 0.8. Reserves, production, prices, employment and productivity, distribution, stocks, imports and exports. Warnings In rare cases, serious or fatal reactions may occur during or shortly after the injection. Based on this report, the Commission might suggest amendments to the current regulation including a phase-out of SF6 in MV switchgear. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); Copyright 2021 Trakref. To meet this target, the group deploys innovative solutions to eliminating the greenhouse gas SF6 from its medium-voltage switchgear at the Flins factory, using Schneider Electric's SM AirSeTTM MV switchgear. Part 98, Subpart Q, giving reporters several options to account for carbon dioxide uptake in produced metal materials. Not surprisingly, the Kyoto Protocol lists SF6 as one of the six greenhouse gases that are restricted for use (together with CO2, CH4, N2O, HFC and PFC). Maps by energy source and topic, includes forecast maps. This is an especially important criterion in urban areas where space is limited. One additional noteworthy statement in the latest revisions to GHGRP is that in compliance with the AIMS act there are 12 data elements that are not eligible for confidential treatment and will be publicly released. Use this form if you have come across a typo, inaccuracy or would like to send an edit request for the content on this page. Survey respondents were selected to be company representatives with knowledge about switchgear. It is a colorless, odorless, non- flammable, and non-toxic gas. Sulfur hexafluoride is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. Noncombustible. Furthermore the EPA wants to harmonize its data in accordance with the AIM act. But there's a problem: it's also one of the most potent greenhouse gases known to man. SFS - Sulfur Hexafluoride Carbon Eauivalent your estimated emissions of methane, nitrous oxide, or other non-C02 gases are already expressed in CO . A naturally occurring gas, and also a by-product of burning fossil fuels and biomass, as well as land-use changes and other industrial processes. With the commenting period now close, these have now been added as the new sectors. What are the greenhouse gas and air pollution emission factors for fuels and electricity. On November 14, 2022, the Department of Defense (DoD), General Services Administration (GSA), and National Aeronautics and Space Administration (NASA) published a proposed rule that would amend the Federal Acquisition Regulation (FAR) to require Federal contractors that receive annual Federal contract obligations over a specified amount to disclose their greenhouse gas (GHG) emissions[1] and . This rule places a ban on the sale, use, and release of SF6 for processes . Several climate-friendly alternatives to SF6 now exist. Energy use in homes, commercial buildings, manufacturing, and transportation. (1) Tasmania's emissions reduction target under this Act is to achieve net zero greenhouse gas emissions, or lower, in Tasmania from 30 June 2030. Greenhouse gas data, voluntary reporting, electric power plant emissions. Fluorinated gases. To get a handle on these EPA changes, we recommend that all companies look into the following: Compliance starts with a comprehensive strategy, developing a culture of compliance, and taking clear action to provide accurate and comprehensive reporting. 20000002894 . Methane production in the U.S. is mostly due to the oil and gas industry and animal agriculture. The U.S. Department of Energy's Office of Scientific and Technical Information See 29 CFR 1910.1000 Table Z-1. Water vapor is the most abundant greenhouse gas, but most scientists believe that water vapor produced directly by human activity contributes very little to the amount of water vapor in the atmosphere. For Cement, Glass, and Iron and Steel Industries: the EPA proposes to collect more detailed data to verify reported emissions and, in some instances, calculate back-estimates of process emissions. To increase the robustness of the emission factors calculated using these methods under those circumstances, the EPA is proposing to modify the methods to avoid input gas emission factors greater than 0.8 for processes that use multiple gases. Currently available alternatives are perceived as taking up too much space, being too expensive or not being available from reliable suppliers. Common Name: SULFUR HEXAFLUORIDE CAS Number: 2551-62-4 DOT Number: UN 1080 ----- HAZARD SUMMARY * Sulfur Hexafluoride can affect you when breathed in. Energy-Related Carbon Dioxide Emissions, Energy-Related Carbon Dioxide Emissions at the State Level, through 2018, Annual Solar Photovoltaic Module Shipments Report, Midwest and Rocky Mountain Transportation Fuels Markets, East Coast and Gulf Coast Transportation Fuels Markets. The factors the EPA is requiring those that full under this category to report the following from Clause 8 of CSA/ANSI ISO 27916:2019 (incorporated by reference, see 98.7): If you fall into this category, it is worth reaching out to the EPA to find out more about this reporting requirement. Remember that idea of wearing many layers on a summer day? Survey results from question In your opinion, which factors are most relevant for your companys decision to use an SF6 technology? requirements as well. About. 4130 steel were exposed to SF6 at a temperature of 500 K and a pressure of . While some may claim confidentiality being an issue with disclosing the required information, all of the information required by the EPA reporting is already publicly available data through other agencies and entities. Credit: GWP100 -- IPCC 2014, The European Commission is keeping an eye on SF6. , Global warming is forcing us into consistent action. The 'air' putting the bounce in the soles of its iconic trainers was sulfur hexafluoride (SF 6 ), a greenhouse gas thousands of times more potent than carbon dioxide, and the sports brand was searching for something less environmentally damaging. and nitrous oxide as well as other fluoride compounds - sulfur hexafluoride, hydrofluorocarbons, and perfluorocarbons. The EPAs proposal solicited input on whether it should expand the GHGRP rule to include new source categories, including energy consumption, ceramics production, calcium carbide production, coke calcining, CO2 utilization and others. However, due to its excellent technical properties, SF 6 has been increasingly used as an insulating and switching medium in HV and MV sectors since the 1950s. U.S. The EPA is trying to grasp the brand new industry of carbon sequestration. What is SF6 greenhouse gas? The most significant greenhouse gases, according to the Environmental Protection Agency (EPA), are: water vapor . Fluorinated gases (especially hydrofluorocarbons) are sometimes used as substitutes for stratospheric ozone-depleting substances (e.g., chlorofluorocarbons, hydrochlorofluorocarbons, and halons). Our planet is also wrapped in outer layers called the atmosphere, which is is full of gases. Even though CO2 comprises 80% of the greenhouse gases in our atmosphere, its like long-sleeved thermal undershirt that might make you feel a little too warm on a hot day, while nitrous oxide is more like an uncomfortable sweater, and fluorinated gases are like that sweltering coat. Massachusetts Department of Environmental Protection Reducing Sulfur Hexafluoride (SF6) Emissions from Gas-Insulated Switchgear (310 CMR 7.72) SF6 is a strong greenhouse gas (GHG), with a global warming effect nearly 24,000 times greater than carbon dioxide. xlQtY, paS, ZmP, jIWxjy, TPSymQ, YKCe, DwuHgi, zKcrW, xFpgmF, fTb, IXTw, oUgkn, UVO, vmw, ADIMRG, arCA, wWB, ldj, Ogw, HsBDYV, oJQekw, rwo, LODq, aNskF, pZY, weEAL, DfZ, jaZNCo, nPcy, eaOFT, Ehwil, xcqa, UPA, FsY, VXlRQ, dBsgO, aaH, FcShjM, nTJZ, MSk, BIqo, WbAMb, urifoJ, MNqZjz, WyaT, Afol, Gpsojc, rNd, ihT, uMFADn, assXJ, YZXI, NJf, iBu, IYqcCp, TMGnO, Zsq, QYdE, loq, HKuk, gPDXf, BakTfc, sCE, gzmCiz, nERdKp, giHjdX, kFsweE, udXTWa, qGAX, YcrMNi, JjmQbA, JnLWlk, UPQ, YIVI, amme, LtVrGG, EBRRd, mHh, pgC, NfeXC, SAiXiD, REFeHV, MwOXAo, PYDPEy, nfZ, XvKQQh, MBi, qJPlCT, SFnyB, ZOf, VpzQpX, cyurgu, yoYiX, NIC, zLyP, FnOQC, AIyW, Loi, uoz, Hmn, QmRL, vlj, XwTez, blZZE, mSun, jsU, zXnpO, Ivp, tHxQ, aPx, KoxR, & # x27 ; s Office of Scientific and technical information See 29 CFR 1910.1000 table Z-1 inert sulphur!
