"The Correlation of Clinical and Environmental Measurements for Workers Exposed to Vinyl Chloride." May 2229, 1970. WebVinyl chloride is a chemical belonging to the family of compounds called organochlorides, which include other highly toxic chemicals including trichloroethane and the infamous pesticide DDT. Supplement 7, 1987. Often, the storage containers for the product vinyl chloride are high capacity spheres. Sherrod Brown (D) and J.D. "For reasons I don't know.". Hence, to save the processing cost for manufacturing ethylene, numerous attempts have been made to convert ethane directly to vinyl chloride. Both pyrolysis and incineration of plastic waste are difficult, complex and multifaceted processes due to several physical and chemical phenomena occurring during their performance. EXPERTS SAY THIS IS AN URGENT MATTER AS DIOXINS DO NOT DEGRADE EASILY. The direct feed of ethane to vinyl chloride plants could thus considerably decrease the raw material costs and make the plants less dependent on cracker capacity. 2016 Mar 5;304:26-39. doi: 10.1016/j.jhazmat.2015.10.014. Vance (R) sent a joint letter to the directors of the Ohio EPA and the U.S. EPA, urging them to monitor East Palestine for dioxins.James Fabisiak, director of the Center for Healthy Environments and Communities at the University of Pittsburgh School of Public Health, first mentioned dioxins to Pittsburgh's Action News 4 on Feb. 7.Fabisiak's thoughts about possible toxins generated by the controlled release included the toxic gases phosgene and hydrogen chloride, both of which were later detected at the site in low quantities.But those two combustion products were not the only harmful chemicals Fabisiak mentioned. Mike DeWine. Inhibited vinyl chloride may be stored at normal atmospheric conditions in suitable pressure vessels. WebThis laboratory investigation aimed at reducing the emissions of pollutants from the batch combustion of three major waste plastics, polyethylene (PE), polystyrene (PS), and poly (vinyl chloride) (PVC). Historically, prior to the 1970s, when the newly Because the combustion of vinyl chloride that They obtained it by treating 1,2-dichloroethane with a solution of potassium hydroxide in ethanol. Study on the Physical, Thermal and Mechanical Properties of SEBS/PP (Styrene-Ethylene-Butylene-Styrene/Polypropylene) Blend as a Medical Fluid Bag. Web1.1 WHAT IS VINYL CHLORIDE? Disclaimer. Abstract. US study establishes link between dioxin and cancer, Video: Residents of East Palestine speak out on poisoning of their town by Norfolk Southern, The East Palestine disaster: A crime of capitalism. And Janet Hill, who lives 1.4 miles away from the derailment, also called for expanded air testing in homes within the evacuation zone. Dioxin formation from waste incineration. Both pyrolysis and incineration of plastic waste are difficult, complex and multifaceted processes due to several physical and chemical phenomena occurring during their performance. Results from those studies of the air in and around East Palestine were released publicly as they became available between Tuesday and Friday. It also led to rare forms of liver cancer called hepatic angiosarcomas and has been labeled a human carcinogen by the International Agency for Research on Cancer (IARC). It can also irritate the eyes, skin, mucous membranes and respiratory tract. Its bread and butter are train crashes and derailments. On Feb. 15, officials held a town hall meeting in the high school gym featuring representatives from the U.S. EPA and other agencies. An analysis of the combustion gases from VCM reveals the following composition: HCl 27,000 ppm, CO2 58,100 ppm, CO 9,500 ppm, phosgene 40 ppm and VCM trace. Do you live in East Palestine or a neighboring community? "Working Conditions and Measures for Their Improvement in Production and Use of Vinylchloride Plastics" (1949). Last Saturday, Ohio Sens. The chemical industry's secrets,", National Emission Standards for Hazardous Air Pollutants (NESHAP) for Vinyl Chloride Subpart F, OMB Control Number 2060-0071, EPA ICR Number 0186.09 (, EPA Toxicological Review of Vinyl Chloride in Support of Information on the IRIS. 1. We highly suspect these chemicals were generated, Gao said. Since it is a gas under most ambient conditions, primary exposure is via inhalation, as opposed to the consumption of contaminated food or water, with occupational hazards being highest. He did not say whether the methods being used would effectively test for dioxins. J Extra Corpor Technol. The most toxic form, 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), is the contaminant found in the herbicide used during the Vietnam WarAgent Orangeand at Love Canal, New York, and Times Beach, Missouri (December 1982). If vinyl chloride starts to leak from the internal sphere or if a fire is detected on the outside of the sphere then the contents of the sphere are automatically dumped into an emergency underground storage container. Vinyl chloride yields average 2050% per pass. "Because we're getting close to planting season around here and there are crops that will take this stuff up. 1971 Mar;32(3):153-6. doi: 10.1080/0002889718506429.

EPA is working with our federal and state health partners to determine if additional sampling is needed and is prepared to assist. Theres another class of chemical called dioxins, Fabisiak said Feb. 7, explaining that dioxins have been found to form when organic chemicals burn, for instance when garbage or medical waste is incinerated. Before For some residents living in and around the area evacuated due to the train derailment a week after the derailment, concern about toxic contaminants lingering in the environment continued. Role of chlorine in combustion field in formation of polychlorinated dibenzo-p-dioxins and dibenzofurans during waste incineration. US SECRETARY OF TRANSPORTATION PETE BOOTED JUDGE MADE HIS FIRST TRIP TO EAST PALESTINE TODAY TO TOUR THE DERAILMENT SITE. Vinyl chloride is also produced as a combustion product in tobacco smoke. EPA did monitor for phosgene and only had a short-term detection of around 3 parts per billion immediately downwind and at the initiation of the control burn, he wrote. [37] Vinyl chloride monomer, a component in the production of poly(vinyl chloride) (PVC) resins, is a halogenated hydrocarbon with acute toxic effects, as well as chronic carcinogenic effects. Vinyl chloride is a dangerous chemical, so the recent derailment and fire of a train carrying a large quantity of it is bad news. The major uses of polyvinyl chloride are as follows:-. CTEH, which merged three years ago with the Montrose Environmental Group, has a dubious past of conducting inaccurate testing with the protection of the company hiring them in mind. Wilson, Rex H et al. 2005 Dec 15;39(24):9452-6. doi: 10.1021/es050707r. Studies of populations exposed in Taiwan in 1979 during pregnancy or breast feeding found that babies had impaired cognitive development, chronic behavioral issues and infertility. Vinyl chloride monomer is among the top twenty largest petrochemicals (petroleum-derived chemicals) in world production. FOIA "This has to be tested for fairly quickly," Caggiano said. Thats why that controlled burn the other night was so important to get right. It is also called vinyl chloride monomer (VCM) or chloroethene. Rail workers: What are your working conditions like, and what do you think is necessary in order to win this struggle? 2nd edition. All submissions will be kept anonymous. [11][12], Ethane is readily available, particularly on the U.S. Gulf Coast. WebFour methods of decomposition were studied: (1) thermal degradation of PVC in a resistively heated furnace, (2) electrical overloading of a PVC clad wire, (3) electrical arcing sharing sensitive information, make sure youre on a federal Many of the workers developed a rare skin condition known as chloracne caused by exposure to these toxic agents. In contrast to ethylene, which easily undergoes chlorine addition, ethane must first be functionalized by substitution reactions, which gives rise to a variety of consecutive and side-chain reactions. Viola, P L. "Carcinogenic Effect of Vinyl Chloride" Presented at the Tenth International Cancer Congress. [3] Vinyl chloride is a flammable gas that has a sweet odor and is carcinogenic. But without more data, Gao said, it is impossible to know if these chemicals had ever formed in the fire at all, much less whether they remained in the air or water. Conversely, with its high content of chlorine, PVC is frequently branded as a major chlorine donor and spitefully leads to substantial formation of dioxins during poorly controlled or uncontrolled combustion and open fires. "They haven't [tested] yet," said Stephen Lester, science director at the Center for Health, Environment, and Justice. Do you work at Norfolk Southern or another Class I railway? In the very first study about the dangers of vinyl chloride, published by Patty in 1930, it was disclosed that exposure of test animals to just a single short-term high dose of vinyl chloride caused liver damage. "[44], The bacteria species Nitrosomonas europaea can degrade a variety of halogenated compounds including trichloroethylene, and vinyl chloride.[45]. Several of those combustion products of vinyl chloride are potential health dangers, he said. [5][6], Vinyl chloride, also called vinyl chloride monomer (VCM), is exclusively used as a precursor to PVC. Active Sr substituted LaMnO 3 perovskite type catalysts were prepared by sol-gel method and further modified by acid, and the catalytic activity for vinyl chloride (VC) combustion were investigated. Clipboard, Search History, and several other advanced features are temporarily unavailable. In the 1970s and 1980s, the Great Lakes waters were polluted with PCBs, leading to significant declines among lake trout and minks. Sil Caggiano, a hazardous materials specialist who was also sitting on the panel, echoed Lester's warning. (PVC is not a known or suspected carcinogen.) Due to its hazardous nature, vinyl chloride is not found in other products. The article analyzes the thermal degradation in the inert and oxidative atmosphere of waste vinyl panels, the main component of which is PVC. (4) The odor threshold for vinyl chloride ranges from 260 ppm to 4,000 ppm. Countless animals have been found dead in the vicinity of the spill. Questions surrounding the highly toxic air pollutants emerged Feb. 23 at an informational meeting for residents, hosted by River Valley Organizing. When vinyl chloride producers shifted to using the thermal cracking of EDC described above, some used byproduct HCl in conjunction with a colocated acetylene-based unit. Partway into the question-and-answer session one woman in the crowd asked if agencies had tested for dioxins. EDC thermally converts into vinyl chloride and anhydrous HCl. TheNational Priorities Listupdated and kept by the EPA added two additional sites in the December 22, 2022 Federal Register, bringing the total to 1,336 uncontrolled hazardous waste sites across the country. Partway into the question-and-answer session one woman in the crowd asked if agencies had tested for dioxins. US EPA considers future tests for dioxins in East Palestine, ANGER AND FRUSTRATION WERE PALPABLE AT THIS MEETING ON MARKET STREET, WHERE BOTH RESIDENTS AND EXPERTS ALIKE WERE MYSTIFIED THAT THERE APPEARS TO BE NO TESTING BEING DONE FOR DIOXINS, WHICH ARE HIGHLY TOXIC AIR POLLUTANTS THAT CAN CAUSE CANCER AND POTENTIALLY LEAD TO DEVELOPMENTAL AND REPRODUCTIVE PROBLEMS. On Friday, Charles Rodriguez, a community involvement coordinator for the EPA, said in an email that the EPA did detect some phosgene, but not enough to be dangerous. Midland Michigan. WebVinyl chloride had a biodegradation rate of 1.456 ug/g soil/hr in soil. "Pathology of Vinyl Chloride" International Congress on Occupational Health. This dates back to the late 1970s Love Canal disaster, in which long-term exposure to then undisclosed dumping of more than 22,000 tons of chemicals by Hooker Chemicals and Plastics Corporation had been happening since the 1940s and 1950s. Product purity and yields are generally very high. Keywords: Although residents of East Palestine were given the all clear sign, as soon as they entered their homes they faced a barrage of strong acrid odors which led to fits of coughing, reddened eyes and inflamed nasal passages and throats, all from inhaling the air. Unable to load your collection due to an error, Unable to load your delegates due to an error. Vinyl chloride (vi-null klor-ide) is a gas at room temperature that burns easily. 2022 Oct 30;15(21):7636. doi: 10.3390/ma15217636. [27] In 1954, B.F. Goodrich Chemical stated that vinyl chloride caused liver injury upon short-term exposures. Tribukh, S L et al. [2] The United States remains the largest vinyl chloride manufacturing region because of its low-production-cost position in chlorine and ethylene raw materials. I couldnt predict but I would find it an interesting question to know whether things like dioxins are being produced.. "Lester was one of several environmental and health experts who sat on a panel to answer residents' pressing questions at the meeting Feb. This colorless compound is an important industrial chemical chiefly used to produce the polymer, poly(vinyl chloride) (PVC). Pittsburghs Action News 4 first reached out to Fabisiak, who directs the Center for Health Environments and Communities at the University of Pittsburgh, on Tuesday evening in hopes of understanding what chemicals may be lingering in the air or water surrounding the train derailment in East Palestine. Meanwhile, the citizens of East Palestine and Darlington Township have been assured: the air in their community is safe to breathe. [2], The thermal cracking reaction is highly endothermic, and is generally carried out in a fired heater. Indeed, the controlled release and burn have created an environmental disaster and the residents of East Palestine and surrounding regions are the guinea pigs in what is shaping up to be another historic example in a series of environmental disasters that have afflicted the working class populations who reside by the railways and roads that transport these toxic substances unbeknownst to them. With, I hope, at least some measure of follow-up on community health, Fabisiak wrote in an email. [2], Until 1974, vinyl chloride was used in aerosol spray propellant. The U.S. Environmental Protection Agency detected what one expert called significant levels of fine particles in the air during the hours following the controlled release of vinyl chloride from train cars that derailed in East Palestine, Ohio. More than two weeks after the "controlled release" of vinyl chloride in East Palestine, Ohio, the U.S. Environmental Protection Agency was still considering whether to test for dioxins. MIKE VALENTE, PITTSBURGH, ACTION NEWS 4. On standing[clarification needed], vinyl chloride can form peroxides, which may then explode. Atmospheric chemists have said the environmental pollutants are possible byproducts of the fire on Feb. 6. Unauthorized use of these marks is strictly prohibited. SOMETHING THAT FROM OUR PIECE OF THE PUZZLE DOT WE WERE WORKING ON FROM DAY ONE AND MAKING SURE WE DO SOMETHING FOR THE FUTURE. The case of dioxin poisoning of Ukrainian politician Viktor Yushchenko in 2004 with TCCD is a textbook case of this disease. Lester warned that dioxins do not degrade easily and can accumulate in the soil, noting that dioxins can lead to cancer, as well as developmental and reproductive problems. The reaction must, therefore, be kinetically controlled in order to obtain a maximal vinyl chloride yield. Japan. Reprinted from Industrial Medicine and Surgery. It must be kept away from sparks, flames and other ignition sources. In a recent opinion piece for theGuardian,Lester adamantly insisted that testing for dioxin should be mandatory. The consultants have backed the railroad on two other occasions, including in a 2012 $18.5 million settlement where two cleanup workers were burned in a fire. PITTSBURGH ACTION NEWS FORCE QUESTIONS TO THE EPA THURSDAY ABOUT DIOXINS. It is therefore impossible to know for sure which byproducts are created without experimentation. Vesel A, Zaplotnik R, Primc G, Paul D, Mozeti M. Nanomaterials (Basel). "I'm not quite sure if we're testing for dioxins yet. It is used in solvents in closed systems for various extraction and cleaning purposes in organic synthesis. Thehistory behind dioxin productionand dioxin poisoning is two centuries old, going back to the early industrial manufacture of various chemicals. PMC Particularly, much more attention should be drawn to liver changes. [15][bettersourceneeded], In addition to its toxicity risk, transporting vinyl chloride also presents the same risks as transporting other flammable gases such as propane, butane, or natural gas. Vinyl chloride exists in both gaseous and liquid forms, and has a faint, sweet odor, according to the Agency for Toxic Substances and Disease Registry. "[41], The Houston Chronicle claimed in 1998 that the vinyl industry manipulated vinyl chloride studies to avoid liability for worker exposure and hid extensive and severe chemical spills in local communities. Some processes use an absorber-stripper system to separate HCl from the chlorinated hydrocarbons, while other processes use a refrigerated continuous distillation system.[2]. The coupled TG PVC; Polyvinylchloride; additives; dioxins; emissions; flame retardation; thermal decomposition; uncontrolled combustion. CVOC pollutants mainly include chlorinated aromatic hydrocarbons, chlorinated alkanes, and chlorinated olefins, among which vinyl chloride (VC) is one of the pollutants associated with the highest emissions because of BUT IT JUST IS FACED CRITICISM FOR NOT VISITING THE SITE EARLIER TODAY, HE SAID HE WAS TRYING TO STRIKE THE RIGHT BALANCE BETWEEN SHOWING SUPPORT ON THE GROUND AND ALLOWING THE SAFE. At very cold temperatures, vinyl chloride becomes a liquid, but it evaporates (changes WHO Regional Publications, European Series, No. How the EPA tested for phosgene and hydrogen chloride. EPA HAD TO KNOW THAT THEY HAD A CLAIM BY A QUARTER THAT DIOXIN WOULD BE FAR. Gao, separately, also brought up the possibility of dioxins in the environment. But chemicals that could have posed much greater risk to human health were not detected at dangerous levels, a University of Pittsburgh scientist who reviewed the EPA data confirmed. AN ATTORNEY WAS ALSO ON THE PANEL THURSDAY NIGHT. In 1949, an explosion at Monsantos chemical plant in West Virginia led to exposure of workers to dioxin-contaminated herbicide. We did not detect anything of significance on site, Justice said that evening.But when asked to specify what chemicals they were measuring, and what levels of those chemicals they were looking for, he did not provide specifics.Were still developing those from our subject matter experts at the health agencies, Justice said Tuesday.Information released later in the week made it clear there were already several chemicals the EPA had known to look for, including phosgene and hydrogen chloride.Roughly 24 hours later the evacuation ended, Justice joined a press conference led by Ohio Gov. China is also a large manufacturer and one of the largest consumers of vinyl chloride. Combustion of vinyl chloride can produce dioxins, which are hazardous pollutants. ITS CRIMINAL THAT THEY DIDNT COME FORWARD WITH THAT. The main reaction which yields VCM and HCl is a homogeneous, first order free-radical chain mechanism. Among the dangers are gases called phosgene and hydrogen chloride. Fabisiak explained that vinyl chloride, which is a gas at room temperature, also transforms into other chemicals when it catches fire. Several of those combustion products of vinyl chloride are potential health dangers, he said. Among the dangers are gases called phosgene and hydrogen chloride. I couldnt predict but I would find it an interesting question to know whether things like dioxins are being produced. And Fabisiak wasnt the only one asking about them. My guess is because they know they will find it. It is therefore impossible to know for sure which byproducts are created without experimentation. Several inches of space separate the inside sphere from the outside sphere. J Environ Sci Health A Tox Hazard Subst Environ Eng. Forms highly toxic combustion products such as hydrogen chloride, From the air, he said spectral readings taken from a plane were likely insignificant from a health point of view. Quantification was conducted via combustion ion chromatography (C-IC). Environ Sci Technol. The explosive limits are: lower 4.0%, upper 22.05% by volume in air. A few days later, a spokesperson for the U.S. EPA confirmed his conclusion, issuing this statement to Pittsburghs Action News 4 on Feb. 19: Combustion of vinyl chloride can produce dioxins, which are hazardous pollutants. Any dioxins from the controlled burn would have been dispersed in the atmosphere since February 6. The mechanism of action of dioxins on vertebrate species is through the activation of the Aryl hydrocarbon Receptors (AhR), which are highly conserved proteins thought to be involved in key early development of the embryo, aging, low oxygen states and biological circadian rhythms. Quantification was conducted via combustion ion chromatography (C-IC). Containers used for handling vinyl chloride at atmospheric temperature are always under pressure. Viola began his research looking for the cause of liver and bone injuries found in vinyl chloride workers. Several of those combustion [29] Also in 1963, a Romanian researcher published findings of liver disease in vinyl chloride workers. It can be formed in the environment when soil organisms break down chlorinated solvents. Vinyl chloride that is released by industries or formed by the breakdown of other chlorinated chemicals can enter the air and drinking water supplies. Vinyl chloride is a common contaminant found near landfills. In the past VCM was used as a refrigerant. It is also added to leaded gasoline as a lead scavenger. "Dioxin" is a term for a family of persistent chemicals (i.e., substances that do not break down chemically or break down very slowly) that are created through various natural and synthetic processes including incineration, forest fires, metal smelting and certain industrial operations involving 2005. Porous Carbon-Carbon Composite Materials Obtained by Alkaline Dehydrochlorination of Polyvinyl Chloride. Phosgene, Fabisiak said, had the potential to be immediately dangerous if it was present. Vinyl chloride exists in liquid form if kept under high pressure or at low temperatures. As the World Health Organization notes, 90 percent of human exposure to dioxins comes through the food chain, mainly meat and dairy products, fish and shellfish. Webto form vinyl chloride with the application of heat. I know that it's under discussion. In other words, the data obtained by CTEH is being used to head off any legal claims or actions against the railroad. To give a sense of scale, globally approximately 40 million tonnes of PVC resin are produced per year,[14] requiring a corresponding amount of vinyl chloride monomer. J Environ Sci Health A Tox Hazard Subst Environ Eng. Epub 2015 Oct 22. WebDioxins and polyvinylchloride in combustion and fires. Poly(vinyl chloride) (PVC) is an important synthetic polymer accounting for ca. Lyon. This review on polyvinylchloride (PVC) and dioxins collects, collates, and compares data from selected sources on the formation of polychlorinated dibenzofurans (PCDFs) and dibenzo-p-dioxins (PCDDs), or in brief dioxins, in combustion and fires. This review summarises available dioxin emissions data, gathers experimental and simulation studies of fires and combustion tests involving PVC, and identifies and analyses the effects of several local factors of influence, affecting the formation of dioxins during PVC combustion. TiO 2 MnO x catalyst samples with different Ti/(Ti + Mn) molar ratios (2:3, 3:4, 4:5, 5:6, 6:7 and 1) prepared by the citric acid (CA) sol-gel method were studied in the catalytic combustion of vinyl chloride (VC) emission. Combustion products from vinyl chloride monomer Am Ind Hyg Assoc J. Reducing the Impact of Perfusion Medical Waste on the Environment. Kurt Kohler, a representative for the Ohio Environmental Protection Agency, said that surface water testing was being conducted consistent with established water quality standards. WHO Regional Office for Europe. 2020 Jun;52(2):135-141. doi: 10.1182/ject-1900023. But the question was: how much?We never burn things very efficiently, Fabisiak said Tuesday. A decade later, feed contaminated with TCDD led to a mass die-off of commercially farmed poultry. The hazards of storing and shipping acetylene meant that the vinyl chloride facility needed to be located very close to the acetylene generating facility. The site is secure. Thats why that controlled burn the other night was so important to get right. Were still developing those from our subject matter experts at the health agencies, Justice said Tuesday. 1969. Vinyl chloride.". On Feb. 14, Pittsburghs Action News 4 asked Fabisiaks colleague Peng Gao, an associate professor of environmental and occupational health at the University of Pittsburgh School of Public Health, to put the communitys water contamination into perspective. Vinyl chloride is a gas under most conditions, so exposure to it comes about through inhalation. 91. More than two weeks after the "controlled release" of vinyl chloride in East Palestine, Ohio, the U.S. Environmental Protection Agency was still considering whether to test for dioxins. The Ohio EPA has not yet answered follow-up questions about whether the agency is testing for dioxins or plans to do so in the future. Tell us what you know about the Norfork Southern disaster by filling out the form at the bottom of this article. Many surveys of the voluminous literature have been performed. This production method has become the major route to vinyl chloride since the late 1950s. Vinyl chloride monomer is among the top twenty largest petrochemicals (petroleum-derived chemicals) in world production. Quantification was conducted via This page is no longer being updated as of February 28, 2023. After a lengthy lawsuit by 1,300 former residents of Love Canal, the companies agreed to a $20 million settlement. Bottom line: nothing immediately stands out as threatening or concerning and these findings do support a decision to allow people to return home. The remainder goes into the production of chlorinated solvents, primarily 1,1,1-trichloroethane (10 000 tonnes/year). He revealed there that the EPA had, in fact, been searching for vinyl chloride, along with its toxic byproducts. They published an inventory of dioxin sources and devoted an enormous amount of time to studying dioxins. PVDC has a CAS number of 9002-85-1. We highly suspect these chemicals were generated, Gao said. It can be easily evaluated under laboratory condition using a mixture of nitrogen and oxygen. I definitely do not recommend the residents consume the food produced close to the accident. Results are reported herein on the emissions of CO, light aliphatic hydrocarbons, polycyclic aromatic hydrocarbons (PAHs), and particulates. Prolonged exposure can lead to liver damage. Acetylene reacts with anhydrous hydrogen chloride gas over a mercuric chloride catalyst to give vinyl chloride: The reaction is exothermic and highly selective. It can be formed when other substances such as trichloroethane, trichloroethylene, and tetrachloroethylene are broken down. PEMA launches dashboard on East Palestine train derailment, NTSB releases preliminary report on East Palestine train derailment, Buttigieg visits East Palestine train derailment site, included the toxic gases phosgene and hydrogen chloride. Vinyl chloride was first reported to induce angiosarcoma of the liver in 1974[33] and further research has demonstrated the carcinogenicity of VC to other organs and at lower concentrations,[34][35] with evidence now extending to jobs associated with poly(vinyl chloride) exposure, indicating the need for prudent control of PVC dust in the industrial setting.
