Lub npe | Characteristic | Harm |
---|---|---|
Carbon dioxide (CO2) | Colorless and odorless | When the concentration is between 7% thiab 10%, it suffocates and causes death |
Dej (H2O) | Steam | |
Cov pa roj carbon monoxide (CO) | Colorless, tsw tsw, highly toxic, nplaim taws | Death caused by concentration of 0.5% hauv 20-30 feeb |
Sulfur dioxide (SO2) | Colorless and odorless | Short term death caused by 0.05% concentration |
Phosphorus pentoxide (P2O5) | Causing cough and vomiting | |
Nitric oxide (NO) and nitrogen dioxide (NO2) | Smelly | Short term death caused by 0.05% concentration |
Smoke and smoke | Varies by composition |

Tshaj dej vapor, Feem ntau ntawm cov byproducts los ntawm combustion yog detrimental.
Cov pa luam yeeb huab visibility, cuam tshuam kev khiav tawm thaum muaj hluav taws kub los ntawm kev pom tsis pom. Qhov khaus thermal convection thiab hluav taws xob los ntawm kev kub kub combustion tuaj yeem cuam tshuam cov nplaim taws ntxiv, spawning tshiab ignition cov ntsiab lus, thiab tej zaum yuav ua rau explosions. Residues from complete combustion exhibit flame-retardant properties. Combustion halts when carbon dioxide levels hit 30%.
