The aim of this publication is to provide information for assessing and managing risks to people and property, and also to protect trees from unnecessary felling and disfigurement. Key features: Provides information for assessing and managing risks to people and property rovides information on protecting trees from unnecessary felling and disfigurement
"The practice and process of assessing trees for risk is detailed in ISA's Tree Risk Assessment Manual. This new manual is a valuable tool for both the expert and novice risk assessor, and will quickly become one of the most referenced resources on your bookshelf. As the companion publication for the Tree Risk Assessment Qualification course, the manual highlights the critical steps in the risk assessment process - from site analysis to risk evaluation and communicating risk to clients (and everything in between). This publication can be used as a resource to study for the qualification course, as a step-by-step guide to conducting a tree risk assessment, and as a desktop reference for writing reports. A Basic Tree Risk Assessment Form is included, along with a list of common wood decay fungi, and a useful glossary of risk assessment terms."--Publisher description
Dendrogeomorphology Beginnings and Futures: A Personal Reminiscence My early forays into dendrogeomorphology occurred long before I even knew what that word meant. I was working as a young geoscientist in the 1960s and early 1970s on a problem with slope movements and deformed vegetation. At the same time, unknown to me, Jouko Alestalo in Finland was doing something similar. Both of us had seen that trees which produced annual growth rings were reacting to g- morphic processes resulting in changes in their internal and external growth p- terns. Dendroclimatology was an already well established field, but the reactions of trees to other environmental processes were far less well understood in the 1960s. It was Alestalo (1971) who first used the term, dendrogeomorphology. In the early 1970s, I could see that active slope-movement processes were affecting the growth of trees in diverse ways at certain localities. I wanted to learn more about those processes and try to extract a long-term chronology of movement from the highly diverse ring patterns.
Explains in detail how to perform the most commonly used hazard analysis techniques with numerous examples of practical applications Includes new chapters on Concepts of Hazard Recognition, Environmental Hazard Analysis, Process Hazard Analysis, Test Hazard Analysis, and Job Hazard Analysis Updated text covers introduction, theory, and detailed description of many different hazard analysis techniques and explains in detail how to perform them as well as when and why to use each technique Describes the components of a hazard and how to recognize them during an analysis Contains detailed examples that apply the methodology to everyday problems
Defective trees are potential hazards to people and property in recreation areas. Most reported tree failures within recreation sites in the Rocky Mountain Region occur in lodgepole pine. Defective root systems account for the greatest percentage of failures. External indicators of defects are used to identify trees that may fail. Some tree species, particularly aspen, are highly susceptible to visitor damage; managers should restrict recreational development in such forest types. Old growth spruce-fir stands should also be avoided for developed sites. Systematic, annual, documented inspections of trees in recreation sites and corrective action are recommended to reduce hazards to the public.
Plant Hazard Analysis and Safety Instrumentation Systems, Second Edition serves as a comprehensive guide to the development of safety instrumented systems (SISs), outlining the connections between SIS requirements, process hazard analysis, SIS lifecycle, implementation, safety analysis, and realization in control systems. The book also explores the impact of recent advances, such as SIL, SIS, and Fault Tolerance. In addition, it facilitates the linkage between SIS requirements and process hazard analysis for the completion of SIS lifecycle implementation. The author, drawing from over 35 years of industrial experience, incorporates practical examples throughout the book. Other sections cover...
