Introduction
Hazards involving the use of electricity at work in potentially explosive atmospheres are of great significance to many industrial situations. The legislation and approach taken by different countries may be different but the overall goal is the prevention of explosions and fires caused by electrical equipment where flammable gas, dust or metals are present.
The course looks at the historical development of zones (Europe) and Divisions (USA) and the work of the International Electro-technical Commission, the NFPA, OSHA, ATEX and IEC Standards IEC 79 and how this affects the certification of an electrical installation in a hazardous atmosphere of a plant.
The sources of ignition, flammability of gases and the high costs of fires and explosions will be discussed. Area classification and how it is decided upon together with the consideration of factors like ventilation and rates of release will also be dealt with.
