If breathed in, carbon monoxide blocks oxygen in the blood from being
delivered to the rest of the body. Prolonged exposure can lead to brain damage
and even death.
It is released by the incomplete combustion of fuels such as natural gas,
charcoal, gasoline, and tobacco.
Sometimes referred to as the “silent killer”, carbon monoxide can for instance
be released in homes by heating systems that do not work properly, claiming many
lives every year.
