1989年2月4日,陕西秦岭发电厂失火,参加灭火的工人田某,使用手提式干粉灭火器时,因灭火器喷不出粉,突然爆炸,下封头从与简体对接的焊缝处断开飞出,击中胸部倒地,致使右胸多发性肋骨骨折,造成气胸、血胸,经抢救无效死亡。分析这次事故的原因主要是: (1)灭火器制造质量低劣。灭火器下封头与筒身对接的焊缝,焊透部分只占全部焊缝的9.08％。 (2)干粉结块。事后检查发现,灭火器出粉管被坚硬的粉柱堵塞(造成结块堵塞原因不明),致使筒体充压后无处释放。如果焊接质量合格,即使出粉管堵塞,灭火器也不至于爆破。 (3)灭火器的维修不认真。这台灭火器曾送西安某灭火器维修单位装修,重新装了
February 4, 1989, Shaanxi Qinling power plant fire, to participate in firefighters Tianmou, the use of portable dry powder fire extinguishers, because the fire extinguisher spray powder, a sudden explosion, the next head from the butt with simplified butt off Fly out, hit the chest fell to the ground, resulting in multiple fractures of the right rib fractures, resulting in pneumothorax, hemothorax, death by rescue ineffective. The main reasons for the analysis of this accident are: (1) The manufacturing quality of fire extinguishers is poor. Fire extinguishers under the head and barrel docking weld, penetration of only 9.08% of the total weld. (2) dry powder caking. After the inspection found that the fire extinguisher powder tube is blocked by a hard powder column (resulting in caking blockage for unknown reasons), resulting in the release of pressure cylinder nowhere. If the welding quality, even if the powder tube is blocked, the fire extinguisher will not burst. (3) Fire extinguisher maintenance is not serious. This fire extinguisher had to Xi’an fire extinguisher maintenance unit renovation, re-installed
