Application of Inherent Safety in Improving the Hazardous Area Classification Framework of Process Plant

This project basically is done for hazardous precautions improvement. Hazardous area
classification (HAC) is one of the methods in analyzing hazards into specific class due to
the mode of the hazards occurred. Hazardous area can be defined as an area which an
unstable gas atmosphere is presents in quantities and needed some special safety
precautions.
From the early stage of designing a plant, HAC has been developed but unfortunately,
there is no improvisation consecutively to have a safer plant area. In order to attain a less
harmful plant area, this project would propose the Inherent Safety approach to the HAC
presented.
Inherent Safety concept is an approach to chemical accident prevention that differs
fundamentally from secondary accident prevention and accident mitigation. Encouraging
the industrial firm to perform an inherent safety opportunity audit to identify where
inherently safer technology is needed, a technology options analysis and to identify
specific inherently safer options will advance the adoption of primary prevention
strategies that will alter production systems so that there are less inherent safety risks.
Based on the HAC framework that has been developed earlier, any method of Inherent
Safety concept will then be implemented for a risky area improvement. The method
might not suitable to be applied to all area, but it could somehow be appropriate for
certain section only.
For the area that could have a safer zone, the technique to handle any installation would
be much better out of harm's way. With this way, certain plant region would be more
secured towards the plant personnel.
