Can Air Ducts Hold Carbon Monoxide If Not Cleaned?
Carbon monoxide - CO - is an odorless, tasteless, colorless and toxic gas.
Carbon Monoxide poisoning symptoms
Low to moderate poisoning
- headache
- fatigue
- shortness of breath
- nausea
- dizziness
Severe poisoning
- confusion
- airsickness
- loss of muscle coordination
- unconsciousness
Carbon monoxide is a by-product from combustion processes. Any combustion process, fuel burning appliance, vehicle or other device has the potential to produce toxic carbon monoxide gas.
Carbon monoxide is dangerous because information technology inhibits the claret'southward power to carry oxygen to vital organs such every bit the heart and brain. Inhaled CO will combine with the oxygen carrying hemoglobin in the blood and will course carboxyhemoglobin (COHb) which is non usable for oxygen send.
Health furnishings of Carbon Monoxide
| Exposure (hours) | CO Concentration (ppm)1 | ||
|---|---|---|---|
| Perceptible | Sickness 3) | Deadly 4) | |
| 0.five | 600 | 1000 | 2000 |
| 1 | 200 | 600 | 1600 |
| 2 | 100 | 300 | thousand |
| iv | 50 | 150 | 400 |
| 6 | 25 | 120 | 200 |
| eight | 252) | 100 | 150 |
1) ppm - parts per million - is defined equally the mass of the component in solution divided by the total mass of the solution multiplied by x6 (i 1000000)
2) The maximum exposure allowed by OSHA in the workplace over an eight hour period is 35 ppm.
3) Typical sickness symptoms are mild headache, fatigue, nausea and dizziness.
4) A CO concentration of 12-13000 ppm is deadly after ane-3 minutes. A CO concentration of 1600 ppm is deadly after one 60 minutes.
| Concentration of CO in air (ppm) | Inhalation Time | Toxic Symptoms |
|---|---|---|
| 9 | Brusque term exposure | ASHRAE recommended maximum allowable concentration in living expanse. |
| 35 | 8 hours | The maximum exposure allowed by OSHA in the workplace over an 8 hr menses. |
| 200 | 2-3 hours | Slight headache, tiredness, fatigue, nausea and dizziness. |
| 400 | 1-two hours | Serious headache-other symptoms intensify. Life threatening afterwards iii hours. |
| 800 | 45 minutes | Dizziness, nausea and convulsions. Unconscious inside 2 hours. Death afterward ii-3 hours. |
| 1600 | twenty minutes | Headache, dizziness and nausea. Expiry inside 1 hour. |
| 3200 | 5-x minutes | Headache, dizziness, nausea. Death inside 1 hour. |
| 6400 | 1-2 minutes | Headache, dizziness, nausea. Death within 25-xxx minutes. |
| 12800 | i-3 minutes | Decease inside ane-3 minutes |
