家庭防震準備：把知識變成東西

一、先修屋子，再修包

多數室內傷亡不是房屋倒塌造成的，而是家具傾倒和物品墜落。這部分風險最容易消除，成本也最低。

• 高柜必須固定。 書柜、衣柜、冰箱、電視柜,凡是高度大于寬度兩倍的，用 L 型角碼或防傾倒帶固定到承重墻的實體部位——注意避開石膏板空腔，要打到龍骨或磚體上。
• 重物放低處。 重箱子、行李箱、大件家電不要放柜頂。廚房櫥柜加裝門扣，防止震動中柜門彈開、餐具傾瀉。
• 床頭是重點區。 床頭上方不要掛畫框、鏡子、空調外機支架、吊燈。睡眠中人反應最慢，這是最不該省的一處。
• 留出逃生路徑。 門口和主通道不堆雜物；玻璃隔斷、落地鏡貼防爆膜。

二、應急包：夠撐 72 小時

放在玄關或床邊隨手可取的位置，全家一包，另在車里備一份小的。

必備：飲用水(每人每天 3 升，備 3 天)、壓縮餅干或能量棒、手電筒(優先手搖或備用電池)、哨子(比呼喊省力得多，是關鍵物品)、充電寶、備用現金與零錢、常用藥與個人處方藥、急救包(紗布、繃帶、消毒用品)、厚手套、口罩(防粉塵)、多功能刀、保溫毯。

容易被忽略但很重要：身份證與重要證件復印件、家庭成員照片與聯系方式寫在紙上(手機可能沒電或損壞)、一雙結實的鞋放在床底(震后地面全是碎玻璃)。

每半年檢查一次，更換過期的食品藥品，測試電池。

三、約定與演練

約定一個集合點。 震后手機網絡往往擁堵，全家事先說好：小范圍在小區哪個位置集合，大范圍去哪個應急避難場所。這類場所通常設在公園、學校操場、廣場，有專門標識，值得提前實地走一次，確認路線上有沒有可能垮塌的老墻或狹窄通道。

約定一個"異地聯絡人"。 災區內部的通信可能癱瘓，但打給外地親友常常還能通。全家統一向這位聯絡人報平安、匯總信息，比彼此互找更高效。優先發短信或網絡消息，而不是打電話——占用帶寬小，成功率更高。

實際演練一次。 至少讓家里每個人做一遍"伏地、遮擋、手抓牢"，找到各自房間里最合適的躲避位置。有孩子的家庭尤其重要——震時沒有時間講道理，只有肌肉記憶管用。

最后，打開手機的地震預警功能。 國內多數安卓機型在系統設置的安全或應急功能中自帶該選項，iPhone 用戶可安裝官方或權威機構的預警應用。幾秒鐘的設置，換的是幾秒到幾十秒的反應時間。

結語

防震準備的悖論在于：做得越好，越顯得多余；而它顯得必要的那一刻，已經來不及做了。

但它真正的成本，也不過是一個周末下午。
