家是温馨、安全的港湾,同时也可能存在一些致命的危险:有毒气体、触电、火灾等,都可能对家人的健康和安全构成威胁。近日,美国老房子网站**载文,提醒大家注意家居中可能存在的6个致命危险。
1.下水道臭气含甲烷(沼气)。不少人都为家里厨卫下水道发出的气味而苦恼。下水道发出的臭气主要为含甲烷的沼气,不仅难闻,污染居室,而且有害健康,会导致人**、头晕,注意力不集中,严重的可能导致人动作不协调、四肢发软乏力。如果空气中甲烷含量超过45%就会导致人因缺氧而呼吸困难、心悸、昏迷,甚至窒息而亡。一旦室内甲烷浓度聚集到一定程度,遇到明火还可能引发火灾。专家建议,应定期检查厨房和卫生间的下水管道,遇到接头松动或者漏水,应及时修理、封堵或更换零件。通风管道也应经常检查。
