（三月二十六日）国旗下讲话：安全教育日
我是来自高二六班的xx，非常荣幸能在国旗下代表上周值周班高二六班演讲。今天我演讲的主题是：安全——教育的保障。大家知道吗，三月二十六日是“全国中小学生安全宣传教育日”。 据权威数据显示，我国现有18岁以下未成年人亿人，平均每年意外伤害人数约为4000万人次，医疗费用亿元，平均每年约有万名中小学生非正常伤亡。为推动中小学安全教育工作，降低青少年伤亡事故的发生率，保证青少年健康成长。1996年由国家教育部、公安部等七部委联合发文，确定每年三月份最后一周的星期一作为全国中小学生“安全教育日”，每年确定一个主题。 如果说学生是祖国的花朵，安全就恰如花朵下的土壤，是花朵生长的保障。我的班主任常常教导我说：“一定要注意安全，父母把自己养这么大不容易。”直到我把脚歪到之前，我还不曾意识到安全的重要性。

国旗下安全教育讲话：铭记责任 珍爱生命
老师们、同学们：大家早上好,今天我讲话的题目是“铭记责任，珍爱生命”。对于每个人来说，生命都只有一次。注意安全，就是善待和珍惜生命的一种有效途径，也是对家庭和社会负责任的表现。而在现实生活中，并非人人都具有较高的安全意识。校园安全涉及到的安全隐患有20多种：如食物中毒、运动损伤、网络安全、交通事故、火灾火险、溺水、传染病等。据了解，我国每年约有万名中小学生非正常死亡：中小学生因安全事故、食物中毒、溺水、自杀等死亡的，平均每天有40多人。数字是枯燥的，但它的背后是一个个鲜活的生命。这说明校园安全形势非常严峻。但有关专家认为通过教育和预防，学生意外伤害事故是可以避免的。在这里向全校同学提出如下要求：一、树立自我安全意识。我们要有高度的安全意识、文明意识，要时时想安全，事事讲安全，树立自我安全意识,让安全走进我们的生活，充分认识到安全工作的重要性和紧迫性。各班同学要协助班主任对本班教室里的各种教学设施、用电设备、住宿设施进行一次安全隐患的排查，若发现问题，请及时向班主任汇报，防患于未然。

3月28日国旗下讲话：全国中小学生安全教育日
同学们:早上好当你每天背着书包上学时，看到过指示行人过马路的斑马线吗？当你走到路口，看到过为安全站岗的红绿灯吗？当你乘坐火车、汽车时，听到过“为了您的安全，请不要把头、手伸出窗外”的热情关照吗？在我们记事时，就常听爸爸妈妈说“干什么事，都要注意安全”；走进校门，老师也教我们要注意安全；识字以后，在工地、路口等危险的地方都看到过“请注意安全”、“安全第一”的牌子。安全是我们生活中永恒的主题！只有一生平安，才有美好未来。根据国家教育部规定，从1996年起，每年三月的最后一周的星期一为全国中小学生安全教育日， 今天是全国第十五个校园安全教育日。今年的教育主题是“加强疏散演练确保学生平安”。5月12日四川汶川大地震惊醒了世人，这场灾难夺去了整整几万人的生命。在这场灾难中多少家庭支离破碎，多少亲人生死离别。也许有些同学说地震毕竟发生的概率小，那么我就说说我们身边最近发生的一些事吧。
全国中小学生安全教育日国旗下讲话稿
老师们、同学们，大家上午好!在全国第22个中小学生安全教育日来临之际，河南省教育厅和郑州市教育局今天联合在郑州市实验高级中学举行安全会议和学生的演练活动。我首先代表河南省教育厅向本次活动的承办单位表示衷心的感谢，向辛勤工作在教育一线的各位老师们表示崇高的敬意，向热爱生活，勤奋学习的各位同学表示亲切的慰问。今年的中小学生安全教育活动主题是“强化安全意识，提升安全素养”。我个人认为要想唱响活动，我们需要落实到每一个环节，需要大家做出以下“四个努力”：首先，校长要做出努力。大家知道，校长是学校安全的责任人，所以我们每一位校长在学校的各项工作当中，应该始终把学校的安全，师生的安全放在各项工作的首位。第二，要完善制度，明确责任。学校的教育教学活动、体育娱乐活动、社会实践活动，后勤保障、医疗服务等各方面，我们都要有完善的制度。要明确每一个单位、每一个部门，包括每一位教职工的责任。大家都知道，我这个岗位应该怎么做，防止出现漏洞。第三，我感觉到要根据各个学校的情况，及时全面的进行安全漏洞的排查，发现隐患及时处置，不留漏洞。校长如果把这些事情做好了，可以说，我们就是一个比较安全的校园，我们的责任就尽到了。
XX小学暑假安全教育国旗下讲话稿
XX小学暑假安全教育国旗下讲话稿各位老师，亲爱的同学们，大家好!紧张的一个学期接近尾声了，我们又迎来了盼望已久的暑假。怎样过好这个长假呢?我们有太多的设想与计划，我们有太多的欣喜与希望。可是，这一切，都是建立在安全的基础上的。因此在假期中，我们每一个同学都必须提高安全意识，学会自我保护。今天，我在这里要再三重申和提醒大家：安全是生命之水，文明是幸福之源!假期一定注意安全，希望大家不仅要记在脑子里，更要落实到行动上。希望同学们从以下几个方面做起：1、防溺水事故：溺水事故是夏季在安全方面存在的最大隐患，因为每年在这个季节里我们的周围都会发生许许多多令人惨痛的事故和教训，并且这些教训往往是以生命的失去而作为代价的;而对于一个家庭来讲，孩子生命的失去往往就意味着一个幸福家庭的破裂甚至毁灭。今天，我再次重申，绝对禁止到危险水域玩水。由于天气炎热，这个问题最容易出现，请同学们务必引起注意，坚决做到不在水库或深水区玩耍;不准与同学结伴到无安全设施、不熟悉，无救护人员的水域游泳。游泳时一定要有家长的陪同。
