[Data] Glossary of Terms for Explosion-Proof Areas
A technical guideline covering everything from the basics of explosion protection to design! A reference document summarizing safety technology.
The document "Glossary of Terms for Explosion-Proof Areas" is a technical guideline that covers the fundamentals of "explosion protection," a safety technology that prevents explosions and fires both physically and electrically, from design to implementation. In environments where flammable gases, vapors, and dust are present, it is essential to have knowledge as a legal requirement to protect human lives and equipment in plants and chemical factories, as sparks from electrical equipment or high-temperature parts can become ignition sources, leading to large-scale explosions or fires. This document explains various explosion-proof structures based on the three fundamental principles of explosion protection and the classification of hazardous locations. [Contents] ■ Classification of hazardous locations ■ Major explosion-proof structures ■ Explosion and temperature ratings ■ Equipment protection levels (EPL) *For more details, please download the PDF or feel free to contact us.
basic information
【Main Explosion-Proof Structures (Partial)】 ■Intrinsic Safety Explosion-Proof Structure (i): Safe circuit that does not reach ignition energy from sparks or heat (ia: Zone 0, ib: Zone 1/2, ic: Zone 2) ■Flameproof Structure (d): Container withstands internal explosions and does not ignite external gases (for power equipment such as motors) ■Increased Safety Explosion-Proof Structure (e): Structure with enhanced safety through insulation reinforcement, etc. ■Pressurized Explosion-Proof Structure (p): Protective gas is pressurized inside the container to prevent the intrusion of external gases (such as large control panels) ■Others: Resin-filled explosion-proof (m), non-ignition explosion-proof (n), oil-filled explosion-proof (o), dust explosion-proof (t) *For more details, please download the PDF or feel free to contact us.
