It is poisonous and can be lethal

Carbon monoxide (CO) is a colorless, odorless gas that can be produced during the combustion process in boilers, particularly when the fuel is not completely burned. The primary danger of carbon monoxide is its poisonous nature; it interferes with the body's ability to carry oxygen. When inhaled, carbon monoxide binds to hemoglobin in red blood cells more effectively than oxygen does, leading to suffocation at the cellular level. High levels of CO exposure can result in serious health effects, including headaches, dizziness, confusion, and even death.

Understanding the health implications of carbon monoxide is crucial for anyone working with boilers, as proper ventilation and regular maintenance are essential to prevent the accumulation of this harmful gas. This knowledge highlights the importance of safety measures in boiler operations to safeguard against the poisonous effects of carbon monoxide.
