Chemical Factory, Petroleum Refinery Industry, Medical Drugs Factory, Rubber and Synthetic Resin Factory, Ignitable Gas manufacturing plant, Liquefying Gas Packing Factory and the Campus Semiconductor and Photo electricity relating electronic industry…and so on, must use or produce massive flammable materials, which enable the creation of Explosive Mixture Gas. As a result, if installation of explosion-proof equipments was not adopted in this sort of manufacturing plants, the fire and explosion accidents would be happened easily and suffer damage and loss significantly such as facilities, equipments, people and cost. TFT-LCD (Thin Film Transistor-Liquid Crystal Display) manufacturing industry has invested heavily in building new factory, also in Taiwan becomes the primary technical industry following by the semiconductor industry in twenty-first century. With the large-scale and automation of production equipments, the setting cost had exceeded semiconductor factor gradually. According to the “Enforcement RULES of LABOR SAFETY AND HEALTH FACILITY LAW ARTICLE 177”, it is responsibility of the employer to provide explosion –proof constructions for electronic setting and facility, which must be appropriate to the partition of damage areas, with the vapor of inflammable liquid、 combustible gas or combustible dust except for the detention of deflagration dust, but have potential explosion and fire consideration. However, with the observation of the explosion-proof equipment setting in domestic high technical plants, most of them are more emphasize on the safety of facility area, but less on entire assessment of the manufacture machinery. The purpose of this article is to address how to assess the explosion-proof equipments setting and integrates the principles regarding the chose of explosion-proof equipments. Meanwhile, it shows accuracy and the fastest way to select safe and appropriate explosion-proof electrical facility while establishing machinery, to provide information, which might useful in the TFT-LCD manufacturing field, and provide the documents for learners in the future.
Key words:Hazardous area、electrical apparatus、explosion protection
