Publisher's Synopsis
It is obvious that poor hazardous area classification or undermining the risk of flammable, explosive or toxic atmosphere has caused havoc in our societies and world at large. Human lives, oil & gas installations, chemical companies etc. have in the recent times burnt down due to negligence to acknowledge or not being aware of deadly hazards in form of gas, vapour, or dust within and around the area of operation. Also, many lives have lost due to inhalation of toxic gas like H2S, CO and their like because many are inadvertently not aware of the dangers of the deadly toxic gases in environment. This book "Awareness on Toxic, Flammable and Explosive Atmosphere" is authored to bridge the gap. It is a born out desire to solve one of the world's greatest challenges - sudden death and loss of Assets due to the presence of flammable, explosive or toxic atmosphere.Within the context of this book Hazardous Area Classification is defined as an assessed division of a plant or facility into hazardous and non-hazardous areas and the sub-division of hazardous area into zones. Hazardous zones include: 0, 1, and 2 for gas environment and 20, 21 and 22 for dust environment and their corresponding equipment category 1, 2, & 3 gas and M1 & M2 for dust respectively. These zones in relationship to types of explosive atmosphere they form give rise to types of protection the facility and environs requires taken cognizance the type of gas or dust detection equipment. Degree of Emission and ventilation affect the behaviour of hazardous atmosphere and plays a great role either to increase concentration or reduce concentration of flammable or explosive atmosphere."Awareness on Toxic, Flammable and Explosive Atmosphere" x-rayed zones of hazardous area classifications and equipment category making it easy to comprehend. It offers a great deal to understand hazardous atmosphere better and need to make a good assessment that would be suitable for a particular facility base on prevalent flammable, explosive and toxic gasses.Also, it considered the importance of Auto-ignition Temperature and flash points of materials and equipment as essentials keeping in mind the auto-ignition temperature of the expected hazards from the facility. This book state emphatically the essentiality of Temperature class of equipment & materials to avert installing equipment and materials that would end up generating spark or heat that could destroy the entire facility.Furthermore, it provides detail explanation on Ingress Protection and it significance in Hazardous Area Classification. Finally, let us keep our environment free from toxic, flammable and explosive atmosphere.
