  • OCCUPATIONAL MEDICINE PROGRAM HANDBOOK October 2005
    U.S. DEPARTMENT OF THE INTERIOR OFFICE OF OCCUPATIONAL HEALTH AND SAFETY OCCUPATIONAL MEDICINE PROGRAM HANDBOOK October 2005 This Occupational Medicine Program Handbook was prepared by the U.S. Department of the Interior’s Office of Occupational Health and Safety, in consultation with the U.S. Office of Personnel Management and the U.S. Public Health Service’s Federal Occupational Health service. This edition of the Handbook represents the continuing efforts of the contributing agencies to improve occupational health services for DOI employees. It reflects the comments and suggestions offered by users over the years since it was first introduced, and addresses the findings, concerns, and recommendations summarized in the final report of a program review completed in 1994 by representatives of the Uniformed Services University of the Health Sciences. That report, entitled “A Review of the Occupational Health Program of the United States Department of the Interior,” was prepared by Margaret A.K. Ryan, M.D., M.P.H., Gail Gullickson, M.D., M.P.H., W. Garry Rudolph, M.D., M.P.H., and Elizabeth Odell. The report led to the establishment of the Department’s Occupational Health Reinvention Working Group, composed of representatives from the DOI bureaus and operating divisions. The recommendations from the Reinvention Working Group final report, published in May of 1996, were addressed and are reflected in what became this Handbook. First published in 1997, the Handbook underwent a major update in July, 2000. This 2005 version of the Handbook incorporates the updates and enhancements that have been made in DOI policies and occupational medicine practice since the last edition.

  • Hazard Analysis Fail-Safe Design Redundancy
    Fact Sheet #15 – December 2020 Revision: Five (Sample Posting Below with Downloadable Copy at the bottom of the document) Northeastern University Procedure For Running Unattended Equipment And Experiments Background Equipment and experiments that run unattended during the day and overnight have the potential of causing significant problems and harm to University personnel, facilities, and equipment. Although we discourage this practice as much as possible, particularly when hazardous substances are involved, we do recognize there is a need to run these experiments at certain times. The following procedures should be used as guidance when carrying out such experiments. Hazard Analysis Anyone considering running an experiment unattended should consider the possible hazards that could occur as a result of failures, malfunctions, operational methods, environments encountered, maintenance error and operator error. These hazards can be identified by looking at the system as a whole and identifying which failure(s) could occur. Some examples include: a) Water If water was suddenly interrupted or a hose pulled out or burst, would the system overheat, flood the laboratory, or cause some other problem? b) Signage If appropriate signage was not used, could someone mistake the containers or turn a switch that was intended to remain open/closed? c) Power Interruption If power was suddenly interrupted would the system or safety features for the system also be shut down? Fail-Safe Design Experiments must be designed so that they are “fail-safe”, which means that they will prevent one malfunction from propagating other failures. Fail-safe designs ensure that a failure will leave the experiment unaffected or will convert it to a state in which no injury or damage will occur.

  • Hazard Control Selection and Management Requirements
    ENVIRONMENT, SAFETY & HEALTH DIVISION Chapter 1: General Policy and Responsibilities Hazard Control Selection and Management Requirements Product ID: 671 | Revision ID: 1744 | Date published: 27 May 2015 | Date effective: 27 May 2015 URL: http://www-group.slac.stanford.edu/esh/eshmanual/references/eshReqControls.pdf 1 Purpose This document defines how a risk-based approach is used to determine the need for controls on facilities, systems, or components to protect the public, workers, and the environment. For controls necessary to prevent or mitigate serious events, specific devices and procedures will be formally credited as part of the approved safety envelope. How these controls are selected, evaluated, and approved, and the process for maintaining and modifying controls, are described in these requirements1. As used here, controls and hazard controls mean those engineered, administrative, or personal protective elements that are used to protect against a hazard. Normal process or operational controls are not included in these requirements except to the extent that their use is directly tied to safety. The concept of credited control is well established in the accelerator safety community. The concept of credited control is borrowed from DOE Order 420.2C, “Safety of Accelerator Facilities” (DOE O 420.2C), but this document neither extends the requirements of DOE O 420.2C to non-accelerator hazards nor modifies those requirements for accelerator hazards. The intent is to extend those robust principles to management of controls for non-accelerator hazards of similar risk. 2 Roles and Responsibilities 2.1 Associate Laboratory Director . Ensures that technical systems under his or her directorate’s management are properly analyzed to determine the type and level of controls necessary to control risk to an acceptable level .

  • Redundancy, Business Flexibility and Workers' Security: Findings of A
    International Labour Review, Vol. 140 (2001), No. 1 Redundancy, business flexibility and workers’ security: Findings of a comparative European survey Marie-Laure MORIN * and Christine VICENS ** ll over Europe, the past 20 years have seen profound changes in labour A markets, together with high levels of structural unemployment and growing insecurity. These developments bear witness to the persistent con- flict between an economic rationale — calling for ever-greater business flexibility — and a social rationale demanding a certain degree of job security for workers. Labour market flexibility is generally measured primarily in terms of the impact of employment protection legislation. Some authors consider that legislation hardly affects employment or unemployment in absolute terms (Freyssinet, 2000); others regard it as playing a part in inter-country dis- parities in these respects and emphasize the possible links between the strin- gency of employment protection provisions and the extent of labour turnover, on the one hand, and the average duration of unemployment, on the other (OECD, 1996). Others, again, argue in favour of rethinking the indicators used to measure the effects of employment protection legislation on levels of unemployment, in the light of enforcement procedures and the links between employment protection 1 and other labour market institutions (Bertola, Boeri and Cazes, 2000). In exploring ways of reconciling enterprise flexibility and job security, existing work reflects an obvious dichotomy between corporate management issues — i.e. research into changes in the production system, such as corporate 1 *Research director and studies engineer at the French National Centre for Scientific Research (CNRS). **Studies engineer at the Interdisciplinary Research Laboratory for Human Resources and Employment (LIRHE), University of Toulouse I.

  • Intrinsic Redundancy for Reliability and Beyond
    Intrinsic Redundancy for Reliability and Beyond Alberto Goffi, Alessandra Gorla, Andrea Mattavelli, and Mauro Pezze` Abstract Software redundancy is an essential mechanism in engineering. Different forms of redundant design are the core technology of well-established reliability and fault tolerant mechanisms in traditional engineering as well as in software engineering. In this paper we discuss intrinsic software redundancy, a type of redundancy that is not added explicitly at design time to improve runtime reliability, but is natively present in modern software system due to independent design and development decisions. We introduce the concept of intrinsic redundancy, discuss its diffusion and the reasons for its presence in modern software systems, indicate how it can be automatically identified, and present some current and future applications of such form of redundancy to produce more reliable software systems at affordable costs. 1 Introduction Reliability, which is the ability of a system or component to perform its required functions under stated conditions for a specified period of time [1], is a key property of engineered products and in particular of software artifacts. Safety critical applications must meet the high reliability standards required for their field deployment, time- and business-critical applications must obey strong reliability requirements, everyday Alberto Goffi USI Universita` della Svizzera italiana, Switzerland, e-mail: alberto.goffi@usi.ch Alessandra Gorla IMDEA Software Institute, Spain, e-mail: [email protected] Andrea Mattavelli Imperial College London, United Kingdom, e-mail: [email protected] Mauro Pezze` USI Universita` della Svizzera italiana, Switzerland and University of Milano-Bicocca, Italy, e-mail: [email protected] 1 2 Alberto Goffi, Alessandra Gorla, Andrea Mattavelli, and Mauro Pezze` and commodity products shall meet less stringent, but still demanding customer requirements.
