| Abstract | Gases, vapours, mists and dusts escape during the process of production, transportation and
storage of combustible / flammable materials in the chemical and petrochemical industries,
as well as in the production of mineral oil and natural gas, both onshore / offshore and in
many other sectors. These flammable gases, vapours, mists and dusts, form an explosive
atmosphere with the oxygen contained in the air. In case that the atmosphere is ignited by
some ignition sources, explosions will be taken place which can result in severe harm to
human life and property.
This report provides a brief survey of the essential aspects of explosion protection in term
of electrical and instrument equipments using in explosive condition, starting form basic of
explosion protection, explosion protection concept, type of explosion protection, including
installation and operation of electrical and instrument equipments installed in explosive
atmospheres.
Keywords: Explosion protection, Primary explosion protection, Secondary explosion
protection, Hazardous area, Type of explosion protection, Installation and operation of
electrical equipment in explosion areas, Marking of hazardous area equipment. |
