HOFFMAN, LL.D. / v \ ygfegf *1 U p H s j M A Y , 1922 WASHINGTON GOVERNMENT PRINTING OFFICE 1922 Digitized for FRASER http://fraser.stlouisfed.org/ Federal Reserve Bank of St. Louis Digitized for FRASER http://fraser.stlouisfed.org/ Federal Reserve Bank of St. Louis PREFACE. In continuation of previous investigations into the dust hazard of certain trades/ the present investigation was originally undertaken in behalf of a committee appointed by the National Tuberculosis Association, and while the writer was chairman two preliminary reports were published during 1918 and 1919. It was found imprac­ ticable* however, on the part of the writer to continue his work as chairman of the committee and the investigation was therefore brought to a conclusion entirely on his own responsibility, the strictly medical and radiological work of the inquiry having been assumed by Dr- Edward R. Baldwin, whose report, dated June 11, 1921, is published in Appendix G. This report did not come to my attention until after my own investigations had been completed and on account of its brevity much of the material required for a conclusive opinion is for the time being not available.2 It is to be hoped that sometime in the future the National Tubercu­ losis Association will publish in full detail the results of this investi­ gation, which represents 427 physical and X-ray examinations of stone workers in the Barre district. Of particular interest is the statement that “ expensive silicosis might exist with little or no impairment of health and no manifest physical signs,” a conclusion suggestive of the great practical value of periodical X-ray examina­ tions as a means of disclosing the earliest possible indications of lung damage. My own investigations would have been quite impossible but for the whole-hearted cooperation of the Granite Cutters’ International Association of America and the correlated experience data obtained bulletins Nos. 79, 82, and 231 of the U. S. Bureau of Labor Statistics, Washington, D. C., 1908-1918. 2 Since this report was completed the Barre branch of the Granite Cutters’ International Association has made an agreement with the Presbrey-Leland Co. of Barre, V t., to go into effect Apr. 1,1922, and con­ tinue in force until Apr. 1, 1925. Article VI of this agreement provides as follows: S e c t io n 1. All dust-creating machines must be adequately equipped with dust-removing devices when proven practical, the practicability of such devices to be passed upon in accordance with provisions laid down in Article X X of this agreement [providing for an adjustment committee]. Sec. 2. Within one month from the signing of this agreement a body of six members, to be known as the ‘‘ health committee/’ shall be created. Of the committee three members shall be appointed by the employer and three by the local branch G. C. I. A. It shall be the duty of this committee to investigate, to assist in the development, the perfecting, and the introduction of dust-removing devices; to consider insurance against sickness and improve in every possible way general working conditions. Sec. 3. Funds for the development and experimental work of this committee shall be provided in the following manner: One-hal i o 11 per cent to be deducted weekly from the wage of each member of the local branch G. C. I. A. The employer to set aside each week an amount equal to the total sum derived from the above source. This fund shall be placed in the hands ofa treasurer elected by a majority of the health committee. Should the funds thus provided be either inadequate or more than sufficient for the desired purpose, any necessary modification may be made by mutual agreement. S e c . 4. The health committee shall make a written progress and financial report on or about Apr. 1 and Oct. 1 of each year to the employer and thel ocal branch G. C. I. A. Sec. 5. Should the members of the health committee be unable to agree, any subject in controversy shall be submitted to the adjustment committee in accordance with Article X X of this agreement. This provision is in entire accordance with the results of the present investigation suggesting similar action on the part of other firms or employers desirous of avoiding labor conflicts as the results of prevent­ able conditions affecting the health hazard in particular industries or occupations. The agreement is likewise applicable to other dusty trades subject to an excessive sickness or mortality rate. Ill Digitized for FRASER http://fraser.stlouisfed.org/ Federal Reserve Bank of St. Louis IV PREFACE. through the courtesy and liberality of the Journeymen Stone Cutters’ Association and the Glass Bottle Blowers’ Association. The field investigations were made by an experienced sanitary engineer, thoroughly familiar with occupational disease problems, and I am also obliged to Mr. Sylvester Schattschneider for the results of his corresponding investigations in the limestone districts of Indiana. Every possible opportunity for investigation was extended to me by the manufacturers of the Barre and Bedford districts, who readily granted permission for a complete inspection of their plants, at the same time giving much valuable advice in the furtherance of the inquiry. I am especially indebted to the United States Bureau of Mines, and particularly to Mr. E. A. Holbrook, assistant director, and to Mr. A. C. Fieldner, supervising chemist at the Pittsburgh Experimental Station, for their invaluable cooperation in technical matters largely outside of the plan and scope of my own investiga­ tions. Preliminary results of the work of the Bureau of Mines are included under Appendix E. It is not claimed for the present in­ vestigation that it has been exhaustive or final upon many important matters, which will require further consideration. But it may be questioned whether any corresponding industry has ever before been subjected to an equally extended inquiry, not only into the medical but also into the correlated social and economic facts affecting the welfare of the employees concerned. The results are certainly extremely suggestive 01 the direction in which it will be necessary to initiate radical reforms if a material reduction in mortality and a consequential improvement in health and longevity are to be brought about through the combined action of the employer, the employee, and the State.

  • Lithics, Landscape and People: Life Beyond the Monuments in Prehistoric Guernsey
    UNIVERSITY OF SOUTHAMPTON FACULTY OF HUMANITIES Department of Archaeology Lithics, Landscape and People: Life Beyond the Monuments in Prehistoric Guernsey by Donovan William Hawley Thesis for the degree of Doctor of Philosophy April 2017 UNIVERSITY OF SOUTHAMPTON ABSTRACT FACULTY OF HUMANITIES Archaeology Thesis for the degree of Doctor of Philosophy Lithics, Landscape and People: Life Beyond the Monuments in Prehistoric Guernsey Donovan William Hawley Although prehistoric megalithic monuments dominate the landscape of Guernsey, these have yielded little information concerning the Mesolithic, Neolithic and Early Bronze Age communities who inhabited the island in a broader landscape and maritime context. For this thesis it was therefore considered timely to explore the alternative material culture resource of worked flint and stone archived in the Guernsey museum. Largely ignored in previous archaeological narratives on the island or considered as unreliable data, the argument made in this thesis is for lithics being an ideal resource that, when correctly interrogated, can inform us of past people’s actions in the landscape. In order to maximise the amount of obtainable data, the lithics were subjected to a wide ranging multi-method approach encompassing all stages of the châine opératoire from material acquisition to discard, along with a consideration of the landscape context from which the material was recovered. The methodology also incorporated the extensive corpus of lithic knowledge that has been built up on the adjacent French mainland, a resource largely passed over in previous Channel Island research. By employing this approach, previously unknown patterns of human occupation and activity on the island, and the extent and temporality of maritime connectivity between Guernsey and mainland areas has been revealed.

  • Graveyard Geology
    GRAVEYARD GEOLOGY A Guide to Rocks in Graveyards and Cemeteries Wendy Kirk Department of Earth Sciences, David Cook University College London & Aldersbrook Geological Society London Geodiversity Partnership Introduction Walk around graveyards and cemeteries (in this case, those of London and the southeast of England) and it becomes apparent that, prior to the latter part of the twentieth century, many memorials were made out of just a few different rock types. These were chosen for reasons of appearance, cost, workability and ease of transport to the cemetery, as well as for resistance to weathering and dependence on local regulations. In the last few decades, a range of different, interesting and beautiful stones have appeared, many brought in from abroad, enhancing the diversity of materials used. The intention of this guide is to help a non-specialist identify the main rock types, to recognize some of the varieties and to know where some of these might have come from. Graveyards are a wonderful resource for those with an interest in geology at any level, wildlife, plants, history or sculpture. We hope you gain as much pleasure as we have done. First things first A useful place to start is to be able to distinguish between igneous, sedimentary and metamorphic rocks. Igneous rocks form from melted rock called magma. If this erupts at the surface, it is called lava. It cools and crystallizes quickly, so the grains are too small to see even with a hand lens (magnifying glass). If the lava erupt explosively to form a spray, the cooled fragments are known as volcanic ash.

  • Building Stones of the National Mall
    The Geological Society of America Field Guide 40 2015 Building stones of the National Mall Richard A. Livingston Materials Science and Engineering Department, University of Maryland, College Park, Maryland 20742, USA Carol A. Grissom Smithsonian Museum Conservation Institute, 4210 Silver Hill Road, Suitland, Maryland 20746, USA Emily M. Aloiz John Milner Associates Preservation, 3200 Lee Highway, Arlington, Virginia 22207, USA ABSTRACT This guide accompanies a walking tour of sites where masonry was employed on or near the National Mall in Washington, D.C. It begins with an overview of the geological setting of the city and development of the Mall. Each federal monument or building on the tour is briefly described, followed by information about its exterior stonework. The focus is on masonry buildings of the Smithsonian Institution, which date from 1847 with the inception of construction for the Smithsonian Castle and continue up to completion of the National Museum of the American Indian in 2004. The building stones on the tour are representative of the development of the Ameri­ can dimension stone industry with respect to geology, quarrying techniques, and style over more than two centuries. Details are provided for locally quarried stones used for the earliest buildings in the capital, including A quia Creek sandstone (U.S. Capitol and Patent Office Building), Seneca Red sandstone (Smithsonian Castle), Cockeysville Marble (Washington Monument), and Piedmont bedrock (lockkeeper's house). Fol­ lowing improvement in the transportation system, buildings and monuments were constructed with stones from other regions, including Shelburne Marble from Ver­ mont, Salem Limestone from Indiana, Holston Limestone from Tennessee, Kasota stone from Minnesota, and a variety of granites from several states.

    Economic and Small Business Analysis – Revisions to the Nonmetallic Mineral Processing Plants (Subpart OOO) NSPS EPA-452/R-09-003 April 2009 Economic and Small Business Analysis – Revisions to the Nonmetallic Mineral Processing Plants (Subpart OOO) NSPS By: U.S. Environmental Protection Agency Office of Air Quality Planning and Standards Research Triangle Park, North Carolina U.S. Environmental Protection Agency Office of Air Quality Planning and Standards Health and Environmental Impacts Division Air Benefits and Costs Group Research Triangle Park, NC 2 SECTION 1 INTRODUCTION To meet the requirements of section 111(b)(1)(B) of the CAA, the Environmental Protection Agency (EPA) is currently conducting the second review of the new source performance standards (NSPS) for non-metallic mineral processing plants (NMPP). The NMPP NSPS was promulgated on August 1, 1985 (40 CFR Part 60 subpart OOO, 50 FR 31328) and subsequently reviewed in 1997. Subpart OOO requires new, modified, or reconstructed affected facilities at NMPP to achieve emission levels that reflect the best demonstrated system of continuous emission reduction, considering cost, non-air quality health, environmental, and energy impacts. These emission levels, referred to as “best demonstrated technology (BDT),” are specified in subpart OOO. The purpose of this report is to provide economic and small business impact analyses for the requirements of this NSPS. We include revenue and other economic data for affected industries and businesses in the industry profile for this NSPS, and that profile is included in this report. The analysis will focus on estimating such impacts by providing annualized cost as a percent of sales or revenues for firms in industries likely to be affected by this NSPS.

  • The Implementation of Circular Economy in the Portuguese Natural Stone Sector
    The implementation of circular economy in the Portuguese natural stone sector Hans Ricardo Klünter Master in Management Supervisor: Professor Isabel Duarte de Almeida , Department of Marketing, Operation and Management, ISTCE Business School October, 2020 Department(s) of Marketing, Strategy and Operation The implementation of circular economy in the Portuguese natural stone sector Hans Ricardo Klünter Master in Management Supervisor: Professor Isabel Duarte de Almeida , Department of Marketing, Operation and Management, ISTCE Business School October, 2020 The implementation of circular economy in the Portuguese natural stone sector Hans Ricardo Klünter Abstract This Pedagogical Case project was created from an initial case study in a medium enterprise from the ornamental stones industry. The observation and perception of ornamental/natural stones sector processes, from extraction to processing, brought new approaches on the case. Thus, a decision was taken to develop a Pedagogical Case Study hoping to give an understanding of resource scarcity, sustainability, circular economy and the natural stone production. After introducing the terminology and basic concepts the Portuguese natural stone manufacturer Solancis is presented to underline its exemplary position of environmentally responsible operation. Key elements are highlighted and based on current research in the fields of environmental impact analysis of life cycle assessments and the construction sector with building information modelling in order to propose an innovative business strategy in the natural stone industry. Resulting benefits can be observed in all three dimensions of sustainability and guide to overcome the current challenges of implementing the concept. Energy intensive processes such as the quarrying could be smoothed through circular economy and lower environmental impacts, lower costs and benefit the surrounding communities.

  • Rajasthan Stone Quarries Promoting Human Rights Due Diligence and Access to Redress in Complex Supply Chains
    non-judicial redress mechanisms report series 11 rajasthan stone Quarries promoting human rights due diligence and access to redress in complex supply chains Dr Shelley Marshall MonaSh UniverSity Kate taylor inDepenDent reSearcher Dr Samantha Balaton-chrimes DeaKin UniverSity About this report series this report is part of a series produced by the non-Judicial human rights redress Mechanisms project, which draws on the findings of five years of research. the findings are based on over 587 interviews, with 1,100 individuals, across the countries and case studies covered by the research. non- judicial redress mechanisms are mandated to receive complaints and mediate grievances, but are not empowered to produce legally binding adjudications. the focus of the project is on analysing the effectiveness of these mechanisms in responding to alleged human rights violations associated with transnational business activity. the series presents lessons and recommendations regarding ways that: • non-judicial mechanisms can provide redress and justice to vulnerable communities and workers • non-government organisations and worker representatives can more effectively utilise the mechanisms to provide support for and represent vulnerable communities and workers • redress mechanisms can contribute to long-term and sustainable respect and remedy of human rights by businesses throughout their operations, supply chains and other business re - lationships. the non-Judicial human rights redress Mechanisms project is an academic research collaboration between the University of Melbourne, Monash University, the University of newcastle, rMit University, Deakin University and the University of essex. the project was funded by the australian research council with support provided by a number of non-government organisations, including core coalition UK, homeWorkers Worldwide, oxfam australia and actionaid australia.
