Safeguarding Equipment and Protecting Employees from Amputations


Book Description

OSHA 3170-02R, Safeguarding Equipment and Protecting Employees from Amputation. Amputations are among the most severe and disabling workplace injuries that often result in permanent disability. They are widespread and involve various activities and equipment. (The U.S. Bureau of Labor Statistics 2005 annual survey data indicated that there were 8,450 non-fatal amputation cases - involving days away from work - for all private industry. Approximately forty-four percent (44%) of all workplace amputations occurred in the manufacturing sector and the rest occurred across the construction, agriculture, wholesale and retail trade, and service industries). These injuries result from the use and care of machines such as saws, presses, conveyors, and bending, rolling or shaping machines as well as from powered and non-powered hand tools, forklifts, doors, trash compactors and during materials handling activities. Anyone responsible for the operation, servicing, and maintenance (also known as use and care) of machines (which, for purposes of this publication includes equipment) - employers, employees, safety professionals, and industrial hygienists - should read this publication. Primary safeguarding, as used in this publication, includes control methods that protect (e.g., prevent employee contact with hazardous machine areas) employees from machine hazards through effective machine guarding techniques. In addition, a hazardous energy control (lockout/tagout) program need to complement machine safeguarding methods in order to protect employees during potentially hazardous servicing and maintenance work activities. This guide can help you identify and manage common amputation hazards associated with the operation and care of machines.




Handbook of Composites


Book Description

Today, fiber reinforced composites are in use • properties of different component (fiber, in a variety of structures, ranging from space matrix, filler) materials; craft and aircraft to buildings and bridges. • manufacturing techniques; This wide use of composites has been facili • analysis and design; tated by the introduction of new materials, • testing; improvements in manufacturing processes • mechanically fastened and bonded joints; and developments of new analytical and test • repair; ing methods. Unfortunately, information on • damage tolerance; these topics is scattered in journal articles, in • environmental effects; conference and symposium proceedings, in and disposal; • health, safety, reuse, workshop notes, and in government and com • applications in: pany reports. This proliferation of the source - aircraft and spacecraft; material, coupled with the fact that some of - land transportation; the relevant publications are hard to find or - marine environments; are restricted, makes it difficult to identify and - biotechnology; obtain the up-to-date knowledge needed to - construction and infrastructure; utilize composites to their full advantage. - sporting goods. This book intends to overcome these diffi Each chapter, written by a recognized expert, culties by presenting, in a single volume, is self-contained, and contains many of the many of the recent advances in the field of 'state-of-the-art' techniques reqUired for prac composite materials.

Process Selection


Book Description

The definitive practical guide to choosing the optimum manufacturing process, written for students and engineers. Process Selection provides engineers with the essential technological and economic data to guide the selection of manufacturing processes. This fully revised second edition covers a wide range of important manufacturing processes and will ensure design decisions are made to achieve optimal cost and quality objectives. Expanded and updated to include contemporary manufacturing, fabrication and assembly technologies, the book puts process selection and costing into the context of modern product development and manufacturing, based on parameters such as materials requirements, design considerations, quality and economic factors. Key features of the book include: manufacturing process information maps (PRIMAs) provide detailed information on the characteristics and capabilities of 65 processes and their variants in a standard format; process capability charts detailing the processing tolerance ranges for key material types; strategies to facilitate process selection; detailed methods for estimating costs, both at the component and assemby level. The approach enables an engineer to understand the consequences of design decisions on the technological and economic aspects of component manufacturing, fabrication and assembly. This comprehensive book provides both a definitive guide to the subject for students and an invaluable source of reference for practising engineers. - Manufacturing process information maps (PRIMAs) provide detailed information on the characteristics and capabilities of 65 processes in a standard format - Process capability charts detail the processing tolerance ranges for key material types - Detailed methods for estimating costs, both at the component and assembly level




Phenolic Resins


Book Description

This vastly expanded 2nd edition contains all the new developments since 1985. It describes significant new phenolic resin chemistry, new applications with up-to-date developments, and includes detailed standardized test methods important for ISO 9001 ff certification.




Microserfs


Book Description

From the era-defining author of Generation X comes a novel of overworked coders who escape the serfdom of Bill Gates to forge their own path. They are Microserfs—six code-crunching computer whizzes who spend upward of sixteen hours a day “coding” and eating “flat” foods (food which, like Kraft singles, can be passed underneath closed doors) as they fearfully scan company e-mail to learn whether the great Bill is going to “flame” one of them. But now there’s a chance to become innovators instead of cogs in the gargantuan Microsoft machine. The intrepid Microserfs are striking out on their own—living together in a shared digital flophouse as they desperately try to cultivate well-rounded lives and find love amid the dislocated, subhuman whir and buzz of their computer-driven world.
