#explosion

• Explosion-proof — Preventing, hindering, or resisting deflagrations and explosions; structurally designed to isolate sparks, flames, or high temperatures inside an enclosure, thereby preventing the ignition of a potentially explosive atmosphere in the surrounding environment. It is a mandatory characteristic for electrical and lighting equipment used in hazardous industrial environments, such as refineries or coal mines.
• Firedamp-proof — Designed structurally or chemically treated to prevent the ignition, propagation, or explosion of hazardous underground mixtures of methane gas and air, commonly known as firedamp. In a technical sense, the term describes safety equipment, insulating materials, or sealed electrical devices intended for use in mining environments with a high risk of deflagration.
• Firedamp-resistant — Possessing structural properties resistant to the destructive action of firedamp gas or preventing its ignition; having the quality of being sealed or immune to methane explosions specific to mine galleries. It is used to describe construction materials, heavy machinery, or safety systems optimized for highly volatile underground environments.
• Self-explosive — Regarding substances, chemical mixtures, or devices: self-explosive; possessing the property to decompose violently and detonate spontaneously under the influence of internal factors or minor environmental variations, without requiring an external primer or dedicated detonator. In a technical sense, it describes a critical molecular instability where the thermal propagation reaction is self-sustained.
