Every woodworker knows that dust is dangerous to health; this book provides the professional guidance required to manage it. It covers all facets of dust control so that the process is truly demystified. This is required reading (and viewing) for all woodworkers who care about health and safety.
Dust Control and Air Cleaning covers various areas of concerns in the management of airborne particles and air sanitization. The title provides a comprehensive coverage of the methods in regulating air quality The coverage of the text includes airborne particles and health; the dynamics of particles; and sampling methods. The selection details various air purification methods and technologies such as removal of particles by wet scrubbing; cyclone dust separators; and filter materials and practical filters. The book will be of great use to student and professional building services engineers and technicians.
The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.
Throughout the mining and processing of minerals, the mined ore undergoes a number of crushing, grinding, cleaning, drying, and product sizing operations as it is processed into a marketable commodity. These operations are highly mechanized, and both individually and collectively these processes can generate large amounts of dust. If control technologies are inadequate, hazardous levels of respirable dust may be liberated into the work environment, potentially exposing workers. Accordingly, federal regulations are in place to limit the respirable dust exposure of mine workers. Engineering controls are implemented in mining operations in an effort to reduce dust generation and limit worker exposure.
A former Senior Partner and Global Managing Director at the legendary design firm IDEO shows how to design conversations and meetings that are creative and impactful. Conversations are one of the most fundamental means of communicating we have as humans. At their best, conversations are unconstrained, authentic and open—two or more people sharing thoughts and ideas in a way that bridges our individual experiences, achieves a common goal. At their worst, they foster misunderstanding, frustration and obscure our real intentions. How often do you walk away from a conversation feeling really heard? That it moved the people in it forward in some important way? You’re not alone. In his practice as a designer, Fred Dust began to approach conversations differently. After years of trying to broker communication between colleagues and clients, he came to believe there had to a way to design the art of conversation itself with intention and purpose, but still artful and playful. Making Conversation codifies what he learned and outlines the seven elements essential to successful exchanges: Commitment, Creative Listening, Clarity, Context, Constraints, Change, and Create. Taken together, these seven elements form a set of resources anyone can use to be more deliberate and purposeful in making conversations work.
