Chemical & Response Details
| Also known as | Shaped charge perforating gunsOil well perforatorsWireline perforating chargesWell completion explosivesDownhole shaped charges |
| Appearance | Metal cylindrical assemblies containing multiple shaped explosive charges arranged in a tubular carrier. Typically steel construction with explosive-filled conical liners designed to penetrate well casing and formation rock. |

| Extinguishing | Do not apply foam or water directly; use distance and protective barriers; explosives 1.1D require no fire suppression in immediate area |
| PPE | ⚠️ Level B minimum with fragment-resistant protection; SCBA required; maintain maximum distance; specialized EOD personnel for emergency response |
