课程名称：IEC ex 认证：危险区域分类培训 课程概述：电气和电子设备（如电动机、发电机、变压器、断路器、保险丝、开关、继电器、电磁阀和电阻器）在正常和异常操作过程中会产生大量热量、弧光和火花，这可能在化学品制造、加工或使用的场所引发火灾或爆炸的重大风险。为了最小化由于弧光、火花和热量释放造成的火灾或爆炸风险，至关重要的是，电气和电子设备必须被设计、测试并标识为适合于其安装区域使用。特别是在危险（分类）地点，即可能存在易燃、可燃或可点燃气体、蒸汽、液体、粉尘、纤维或飞扬物的地方，更要如此。危险区域分类是利用科学和工程原理对危险（分类）地点进行评估和分类，主要用于确保在这些区域内安装的电气/电子设备的安全和适当规范。 在本课程中，危害区域分类从IEC、NPFA、CENELEC等多个标准的角度进行研究。危险区域分类通常在设施的平面图（有时也包括立面图）上进行表述，这些图被称为区域分类图。根据区域分类图，可以对电气/电子设备进行正确的规范和安装，从而极大减少火灾或爆炸的风险。课程内容涉及如何简单易懂地阅读这些图示，确保绝对的初学者也能理解。 本课程主要遵循IEC 60079标准，涵盖以下保护技术： - IEC/EN 60079-0 - 一般要求 - IEC/EN 60079-1 - 防爆外壳 'd' - IEC/EN 60079-2 - 加压 'p' - IEC/EN 60079-5 - 填粉 'q' - IEC/EN 60079-6 - 油浸 'o' - IEC/EN 60079-7 - 增加安全性 'e' - IEC/EN 60079-11 - 本质安全 'i' - IEC/EN 60079-15 - 电气设备类型 'n' - IEC/EN 60079-18 - 封装 'm' 这门课程将有效帮助不同领域的人士： 1. 操作工程师：了解危险区域的重要性和范围。 2. 维护工程师：了解应采购哪种设备？如何进行维护？ 3. 安全与过程安全管理（PSM）：增加整体知识，有助于审核和过程危害分析（PHA）。 本课程为相关人员提供了必要的理论基础和实际应用技能，确保他们能够在危险环境中安全、高效地工作。
Electrical and electronic equipment such as motors, generators, transformers, circuit breakers, fuses, switches, relays, solenoids and resistors produce significant amounts of heat, arcing and sparking during normal and abnormal operation, which could pose a substantial risk of fire or explosion in facilities where chemicals are manufactured, processed or utilized. To minimize the risk of fires or explosions that could result from this arcing, sparking and heat dissipation, it is critically important that electrical/ electronic equipment be designed, tested and labeled as being acceptable for use in the areas in which they are installed. This holds especially true for hazardous (classified) locations, i.e. locations where flammable, combustible or ignitable gases, vapors, liquids, dust, fibers or flyings may be present.Hazardous area classification is the evaluation and classification of hazardous (classified) locations using scientific and engineering principles, within facilities where chemicals are manufactured, processed or utilized. Hazardous areas are classified solely for the purpose of ensuring the safe and proper specification and installation of electrical/ electronic equipment located within them. In this masterclass, the Hazardous Area Classification is studied from point of view of various standards like IEC, NPFA, CENELEC etc. A hazardous area classification is typically shown on plan view drawings of the facility (and sometimes on elevation drawings) that are commonly referred to as area classification drawings/diagrams. Based upon the area classification drawings, electrical/ electronic equipment can be properly specified and installed such that the risk of fires or explosions is greatly reduced. This course shows how to read these diagrams in a very easy way so that an absolute beginner is also able to understand.This course mainly follows IEC 60079 standards and following protection techniques are covered:•IEC/EN 60079-0 - General Requirements•IEC/EN 60079-1 - Flameproof Enclosure 'd'•IEC/EN 60079-2 - Pressurization 'p'•IEC/EN 60079-5 - Powder Filling 'q'•IEC/EN 60079-6 - Oil Immersion 'o'•IEC/EN 60079-7 - Increased Safety 'e'•IEC/EN 60079-11 -Intrinsic Safety 'i'•IEC/EN 60079-15 -Electrical Apparatus type 'n'•IEC/EN 60079-18 -Encapsulation 'm' This course will definitely help persons working in different domains in following way:1. Operation Engineer: Knows the significance and extent of Hazardous Area.2. Maintenance Engineer: Which type of equipment to be procured? How to do maintenance?3. Safety & PSM: Increase overall know how and will help in Audit and PHA.
