| Hingoa | Characteristic | Harm |
|---|---|---|
| Carbon dioxide (CO2) | Colorless and odorless | When the concentration is between 7% mo e 10%, it suffocates and causes death |
| Vai (H2O) | Steam | |
| Kaponi kaponi (CO) | Colorless, odorless, highly toxic, velangofua | Death caused by concentration of 0.5% ʻi loto 20-30 miniti ʻe 10 |
| Sulfur dioxide (SO2) | Colorless and odorless | Short term death caused by 0.05% tokanga |
| Phosphorus pentoxide (P2O5) | Causing cough and vomiting | |
| Nitric oxide (NO) and nitrogen dioxide (NO2) | Smelly | Short term death caused by 0.05% tokanga |
| Smoke and smoke | Varies by composition |
Mavahe mei he mao ʻo e vai, Ko e konga lahi ʻo e byproducts mei he afi ʻoku fakatuʻutamaki.
ʻOku fakatokangaʻi ʻe he ngaahi ʻao ʻo e kohu, faingataʻa pupula e ngaahi ngaue ki hono fetukutuku lolotonga e afi ʻaki hono ʻufiʻufi e mata. ʻE lava ʻe he convection lahi mo e hulu mei he afi ʻoku maʻolunga ʻo fakaulo ha ngaahi flammables kehe, spawning ha ngaahi poini ignition foʻou, pea fakatuʻutamaki lolotonga. Residues from complete ʻa e afi exhibit flame-retardant properties. Combustion halts when carbon dioxide levels hit 30%.
