【简答题】
2002年4月24日,在中建某局总包、广东某建筑公司分包的动力中心及主厂房工程工地上,动力中心厂房正在进行抹灰施工,现场使用一台CZ350型混凝土搅拌机,用来拌制抹灰砂浆、上午9时30分左右,由于从搅拌机出料口到动力中心厂房西北侧现场抹灰施工点约有200m左右的距离,两台翻斗车进行水平运输,加上抹灰工人较多,造成砂浆供应不上,工人在现场停工待料。此时身为抹灰工长的非常着急,到砂浆搅拌机督促拌料、因安全意识不足,趁搅拌机操作工去备料而不在搅拌机旁的情况下,私自违章开启搅拌机,且在搅拌机运转过程中,将头伸进料口查看搅拌机的情况,被正在爬升的料斗撞到头部后,人跌倒在料斗的下面,料斗下落后压在的胸部,造成头部大量出血。事故发生后,现场负责人立即将急送医院,经抢救无效,于当日上午10时死亡。 (1)事故的直接原因是什么? (2)事故预防及控制措施
