一氧化碳中毒,习惯称之为煤气中毒,在工业生产和日常生活中都可发生。当含碳有机物,如煤炭、石油、木材等在不完全燃烧的时候都能产生一氧化碳,特别是在空气不够流畅和不充足的情况下,一氧化碳形成就更多。像机械工业的铸造工序,冶金工业的炼焦、炼钢、炼铁业,加热窑炉的焙烧过程,矿下作业、煤制气作业等都可能接触到一氧化碳气体。一氧化碳是一种无味、无臭且不易看见,而比空气又轻的一种毒性很强的窒息性气体。因此国家规定生产作业场所空气中的浓度最高不得超过30毫克/立方米。一氧化碳可以通过人的呼吸进入血液,与血液中的血红蛋白结合成碳氧血红蛋白,使血
Carbon monoxide poisoning, habitually called gas poisoning, can occur both in industrial production and in everyday life. Carbon monoxide is produced when carbon-containing organic substances, such as coal, petroleum, wood, etc., are not completely burnt, and carbon monoxide is more formed, especially when the air is not flowing and inadequate. Like the casting process of the machinery industry, metallurgical industry coking, steelmaking, ironmaking, heating furnace roasting process, mining operations, coal gas operations are likely to come into contact with carbon monoxide gas. Carbon monoxide is a highly toxic asphyxiant gas that is odorless, odorless and hard to see, and lighter than air. Therefore, the state regulations require that the concentration of air in the workplace should not exceed 30 mg / m3. Carbon monoxide can enter the blood through the human breath, combined with hemoglobin in the blood into carboxyhemoglobin, blood
