Which term is associated with dangerous gaseous emission from incomplete burning in engines or heaters?

• A. Carbon Monoxide
• B. Concussion
• C. UV Rays
• D. PFD

Answer: (A)

Carbon monoxide is the term tied to dangerous gaseous emissions from incomplete burning in engines or heaters. When combustion isn’t complete, carbon monoxide is produced, and it’s particularly hazardous because it’s difficult to detect—it's colorless and odorless. It bonds with hemoglobin in the blood much more readily than oxygen, which means it prevents oxygen from being carried to tissues. That can lead to symptoms like headaches, dizziness, and confusion, and in higher exposures, it can be life-threatening. The other terms don’t describe gases from combustion: concussion is a head injury, UV rays are radiation, and a PFD is a personal flotation device.
