1.1 This guide covers the in-service care, inspection, testing, and use voltage of insulating plastic guards (cover-up) for the electrical protection of workers. 1.2 Units— The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 4.1 This guide covers care, storage, inspection, and testing. Work practices vary from user to user and are dependent on many factors. Factors may include, but are not limited to, operating system voltages, configuration of lines and equipment, work procedures, techniques, and weather conditions. It is the responsibility of the user to prepare complete instructions necessary to meet applicable regulations governing the use of insulating plastic guards. Instructions should include electrical testing and inspection procedures. The use of insulating plastic guards should be in accordance with the manufacturer’s instructions or recommendations.
