Q. Hazardous and Safe Areas in plant layout?
Plants implicitly involve identifiable hazards in respect to the environment, location and presence of potentially explosive materials and ignition sources that have an impact on the safety of personnel and the facility / plant. Areas within such facilities require designation in relation to the level of effective safety or absence of particular hazards, and subsequently spaces are allocated for design and operational purposes as being a "Safe Area" or "Hazardous / Explosive Area". The determination and classification of the latter are able to be formalized through the systematic application of hazardous area classification which is prescribed by a wide range of methods; many of which fall under the category of Region or Country specific standards or regulations.
