Many areas around the world suffer from frequent loss of electrical power.
People often must use other sources of power, such as gasoline or diesel fuel.
But these other power sources can be deadly if people do not ventilate the area in which they are used.
The U.S. Centers for Disease Control and Prevention, or CDC, says that about 430 people die every year in the U.S. from accidental carbon monoxide poisoning.
Carbon monoxide is a colorless and odorless gas. All fuel-powered engines produce carbon monoxide.
Recently, carbon monoxide killed eight family members as they slept in their home in the U.S. state of Maryland.
An electric company had cut power to their home because the family owed the company money.
They used an electric heater connected to a small gas-powered generator inside the house.
Patrick Breysse is the director of the CDC Agency for Toxic Substances and Disease Registry. He spoke to VOA on Skype.
He says the signs of carbon monoxide poisoning can be difficult to notice. The gas is colorless. It has no odor or taste.
世界上很多地区经常停电,
人们通常只得使用汽油或柴油等其他能源,
但如果人们在不通风的地方使用这些能源很可能会致命。
美国疾病控制与预防中心(CDC)称美国每年有大约430人死于意外的一氧化碳中毒,
一氧化碳是无色无味的气体,所有以燃料为动力的引擎都能产生一氧化碳。
最近,美国马里兰州一家8口在家中睡觉时死于一氧化碳中毒,
电力公司以欠电费为由切断了这家人的电力,
他们使用连接到小型发电机上的电热器取暖。
帕特里克・布耶西是
美国疾病控制与预防中心有毒物质与疾病登记处主任,他通过Skype接受了美国之音的采访,
他说一氧化碳中毒的迹象很难发觉,这种气体没有颜色,也没有味道。
