静电复印机在工作时,可产生大量的臭氧(O_3)而O_3氧化能力很强,是一种高毒刺激性气体。可对人体产生直接的或潜在的危害作用。能刺激和损害深部呼吸道粘膜和组织,对眼睛亦有刺激作用。当空气中O_3浓度为0.5ppm时,肺部由于水肿而呼吸困难,可引起兴奋、眩晕、疲倦以及血压下降;在0.6～0.ppmg时,暴露2小时可引起胸骨下疼痛及气管刺激性疼痛。6～12小时后一氧化碳扩散能力降低25％。1ppm以上时,可引起肺气肿和肺水 Electrostatic copiers at work, can produce large amounts of ozone (O_3) and O_3 strong oxidizing power, is a highly toxic gas irritant. Can have a direct or potential harm to the human body. Can stimulate and damage the deep respiratory tract mucosa and tissue, but also stimulate the eyes. When the O_3 concentration in the air is 0.5ppm, the lungs have difficulty breathing due to edema, which can cause excitement, dizziness, tiredness and blood pressure drop. When exposed to 0.6 ~ 0.ppmg for 2 hours, it can cause sternal pain and tracheal irritation pain . 6 to 12 hours after the proliferation of carbon monoxide reduced by 25%. Above 1ppm, can cause emphysema and lung water
