Chemical & Response Details
| Also known as | Aerial flaresSignal flaresIlluminating flaresPyrotechnic aerial signals |
| Appearance | Solid pyrotechnic devices containing metal powders (typically magnesium or aluminum) and oxidizers in cylindrical cartridges. Designed to produce intense bright light when ignited. |
| Flash Point | Not applicable (pyrotechnic composition) |
| Boiling Point | Not applicable (pyrotechnic composition) |
| Vapor Density | Not applicable (solid pyrotechnic) |
| Water Reactivity | May react with water if composition contains reactive metals; some formulations contain water-reactive magnesium |
| Extinguishing | Use dry chemical, sand, or dry earth only; avoid water if metal-containing; CO2 and foam generally not effective on burning pyrotechnics |
