Figure 3-33.—Typical ESD ground work bench.Energized equipment provides protection from ESD damage through operating circuitry. Circuitcards with ESD sensitive devices are generally considered safe when installed in an equipment rack; butthey may be susceptible to damage if a "drawer" or "module" is removed and if connector pins aretouched (even putting on plastic covers can transfer charges that do damage). There must not be anyenergized equipment placed on the conductive ESD work surface. An ESD work area is for "dead"equipment ONLY.ESD protection is critical. If you should be assigned to 2M repair school, your education in ESDprevention will be quite extensive.PERSONAL SAFETYThroughout your career you will be aware of emphasis placed on safety. Safety rules remind you ofpotential dangers in work. Most accidents are preventable. Accidents don't happen without a cause. Mostaccidents are the result of not following prescribed safe operating procedures.This would be a good time to review the safety section in topic 5 of NEETS, Module 2, Introductionto Alternating Current and Transformers. That section covers the basics of electrical shock and how toprevent it.The 2M technician should be aware of other potential dangers in addition to the dangers of electricalshock. These dangers are discussed in the following paragraphs.3-43
