Who is affected most easily by carbon monoxide?
The following people are at highest risk in the workplace. This is because of their greater need for
oxygen or an impaired ability of their bodies to provide an adequate supply:
pregnant women
the physically active
older workers
heavy smokers
sufferers from respiratory diseases
sufferers from heart disease
What long-term effects are caused by exposure to carbon monoxide?
Effects produced by exposure to carbon monoxide are generally reversible. That is, the effects disappear
following removal from exposure. In addition, effects produced during one exposure are usually
independent of those produced during any other. Massive overexposure can cause permanent damage.
Damage is most likely to occur in the nervous system. These effects can include:
loss of memory
increased irritability
impulsiveness
mood changes
violent behavior
verbal aggression
personality changes
learning disabilities
mental deterioration
instability when walking
What should be done if overexposure is suspected?
Ensure your own safety before attempting a rescue (wear protective equipment).
Be aware of potential of confined space areas and follow appropriate procedures for entering a
confined space.
Move the victim to clean, fresh air or remove the source of carbon monoxide.
Call the emergency number for help (911 in many cases).
