易爆物質 : 很多生產場所都會(huì)產生某些可燃性物質。煤礦井下約有三分(fèn)之二的場所有存在爆炸性物質;化學工(gōng)業中,約有 80% 以上的生產車間區域存在爆炸性物質(zhì)。氧氣 : 空氣中的氧(yǎng)氣是無(wú)處不在的。點燃源 : 在生產過程中大量使用電氣儀表,各種磨擦的電火花 , 機械(xiè)磨損火花、靜電火花、高溫等不可避免,尤其當儀表、電氣(qì)發生故障(zhàng)時。客觀上很多工業現(xiàn)場滿足爆炸條件。當爆炸性物質與(yǔ)氧氣的混合(hé)濃度(dù)處於爆炸極限範圍內時(shí),若存在爆炸源,將會(huì)發生爆炸。因此采取(qǔ)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.
