易爆物質 : 很多生(shēng)產場所都會產生某些可燃性物(wù)質。煤礦井下約有三分之二的場所有存在爆炸性物質;化學工業中,約有 80% 以上的生產車間區域存在(zài)爆(bào)炸性物質。氧氣 : 空氣中的氧氣是無處不在的。點燃源 : 在生產過程中大量使用(yòng)電氣儀表,各種磨擦(cā)的電火花 , 機械(xiè)磨損火花、靜電火(huǒ)花、高溫等不可避免,尤其當儀表、電氣發生故障時。客(kè)觀上很多工業現場滿足爆炸條件。當爆炸性(xìng)物(wù)質與氧氣的(de)混合濃度處於爆炸(zhà)極限範圍內時,若存在爆炸源,將會發生爆炸。因此采取防爆就顯得很必要了。

Explosive substances: Many production sites produce certain flammable substances. About two-thirds of the underground mines contain explosive substances; in the chemical industry, more than 80% of the production workshop areas contain explosive substances. Oxygen: Oxygen in the air is everywhere. Ignition source: In the production process, a large number of electrical instruments are used, various frictional sparks, mechanical wear sparks, static sparks, high temperature, etc. are inevitable, especially when the instrument and electrical malfunction. Objectively, many industrial sites meet explosion conditions. When the mixed concentration of explosive substances and oxygen is within the explosion limit range, if there is an explosion source, an explosion will occur. Therefore, it is necessary to adopt explosion protection.
