CHAPTER 1THE TECHNICIAN'S HANDBOOKHere, in one compact module, you will be able to find essential information and reference material.Whether you want to know safety precautions, first aid, or any number of helpful pieces of information,you will find it indexed.We have included electrical and electronic formulas, data tables, and general maintenance hints. Inmost cases you will find references to other more detailed sources included.We solicit your suggestions, maintenance hints, and constructive criticism. You will receive credit infuture editions of this handbook if your input is used.MISHAP PREVENTION AND AFTERCAREMost of us working with electricity take risks. Usually we get our jobs done without any harmfulresults. Mishaps or injuries usually result from not understanding a risk or danger.The first part of this handbook is designed to help you eliminate or minimize mishaps. It alsoprovides you with a good review of what to do in case of a mishap.SAFETY OBSERVATIONS FOR THE ELECTRICAL AND ELECTRONICS TECHNICIANWorking safely is the most important thing you can do. Because of their importance, severalprecautions are included as the first subject in this handbook. Of course there are more precautions, butthese are some you should think about. The keyword here is think. Think safety.• Never work alone.• Never receive an intentional shock.• Only work on, operate, or adjust equipment if you are authorized.• Don't work on energized equipment unless absolutely necessary.• Keep loose tools, metal parts, and liquids from above electrical equipment. Never use steel woolor emery cloth on electric and electronic circuits.• Never attempt to repair energized circuits except in an emergency.• Never measure voltage in excess of 300 volts while holding the meter wire or probe.• Use only one hand when operating circuit breakers or switches.• Use proper tag-out procedures for regular and preventive maintenance.1-1
