3D VIEW OF HAZARDOUS AREA CLASSIFICATION USING OPEN SOURCE

This paper presents a development of 3D view of hazardous area
classification using the open source of 3D simulation software, Art of Illusion, for
minimum cost implementation. The 3D simulation is meant to complement the
existing 2D drawing for better hazardous area classification and visualization. The
3D simulation is developed based on the IEC 60079-10 hazardous area guideline. It
is intended as user friendly tools that can be easily used for area hazard analysis such
as identifYing the hazard level and the presence of ignition sources to keep the level
of safety at the highest level. The assessment for the process plant is focus on Crude
and Distillation Unit which typical product are gasoline, diesel fuel, asphalt base,
kerosene, and heating oil and liquefied petroleum gas. The area classification
visualization used the zone classification as the color code i.e. for Zone 0 is red,
Zone I is yellow and Zone 2 is green. The color code is developed based on the zone
in present of flash point, ignition temperature, explosive limit, and vapor density.
Finally the extent of the hazardous zones will be determined based on ideal spherical
ball dispersion. Currently case study have shown different gases with different
properties will give different value of release mass and extent of zone. Current works
have shown that the layout of the process plant can be view from 360 degrees or
from the 3D view. Thus user would be able to rotate the view to assess the overall
area of the hazard zones including the extent of the zones.
