Npe | Characteristic | Harm |
---|---|---|
Carbon dioxide (CO2) | Colorless and odorless | When the concentration is between 7% Thiab 10%, it suffocates and causes death |
Water (H2O) | Steam | |
pa roj carbon monoxide (CO) | Colorless, tsw ntxhiab, highly toxic, qhov khuv | Death caused by concentration of 0.5% tsis pub dhau 20-30 Feeb |
Sulfur dioxide (SO2) | Colorless and odorless | Short term death caused by 0.05% concentration |
Phosphorus pentoxide (P2O5) | Causing cough and vomiting | |

Tshaj ntawd dej vapor, Feem ntau cov byproducts ntawm combustion yog detrimental.
Pa luamyeeb huab visibility, complicating evacuation kev siv zog thaum hluav taws kub los ntawm obscuring pom. Cov khaus thermal convection thiab tawg ntawm high-kub combustion yuav ignite ntxiv flammables, spawning tshiab ignition ntsiab lus, thiab uas ua rau muaj explosions. Residues from complete combustion exhibit flame-retardant properties. Combustion halts when carbon dioxide levels hit 30%.
