Yes guys, carbon monoxide is CO and it is the stuff you should really worry about.
Carbon Dioxide CO2 is not nearly as dangerous. You'd know you're in danger if there is too much CO2.
Yes, seriously, be VERY careful of carbon monoxide. It got to me back in my younger days (early 20's) when I was restoring a car and didn't pay any attention exhaust fumes in the garage. Long story but basically it was young and stupid almost becoming young and dead.
The following are symptoms of carbon monoxide poisoning at low levels of exposure:
- Headaches
- Nausea or Vomiting
- Shortness of Breath
- Fatigue
- Dizziness
Chronic Carbon Monoxide Poisoning
If a person is exposed to low levels of carbon monoxide over a long period of time, they may experience symptoms for a long period of time - even after the exposure to carbon monoxide has ended. This exposure may result in difficulties in the following areas:
Memory and Attention: The person may have trouble recalling recent events, concentrating, or finding the right words to express themselves.
Physical: Headaches, nausea, vomiting, and chronic fatigue are symptoms of chronic carbon monoxide poisoning. In addition, the individual may complain of muscle and joint pain, tingling, and dizziness.
Vision and Balance: Blurred vision, difficulty keeping one's balance, and a buzzing in the ears may also be caused by exposure to carbon monoxide.
Personality Changes: When a person feels irritable or anxious, they may not necessarily connect it to carbon monoxide poisoning, but these symptoms have been linked to long-term exposure to the gas.
