Carbon monoxide poisoning can kill without warning, often when occupants are asleep. Because CO gas has no warning properties even at toxic or life-threatening levels, it is considered a silent killer.
And because so many deaths occur as the result of defective or poorly operated home heating equipment, CO-related deaths make it a cold weather killer.
Although not always experienced, the initial symptoms of CO poisoning are similar to those of the flu but without the fever. These symptoms include dizziness, fatigue, headache, nausea and irregular breathing.
It is critical to note that death from CO poisoning can result with some or a lot these symptoms never being experienced, in which case the victim simply falls asleep and never regains consciousness.
To avoid CO poisoning, follow these tips:
• Appliances designed to be vented should do so properly and according to manufacturers'' instructions.
• Adequate combustion are should be provided to ensure complete combustion.
• All combustion appliances should be installed by professionals.
• Chimneys and flues should be kept free of blockages, corrosion, and loose connections.
• Kerosene and gas space heaters (vented or unvented) should be cleaned and inspected to ensure proper operation.
