cause BLEVE and directly affect the human life’s nearby and working communities
[4]. The release of compressed gases gives rise to be cryogenic stresses and thermal
stresses, which can also impact the surrounding structure and damage to property,
compounding the damage.
Chemical units incorporate a wide scope of risks emerging from the procedure
itself, properties of the synthetic concoctions and their taking care of, for example,
fire, blast and presentation to poisonous substances. Be that as it may, there is a still
genuine capability of major modern mishap with disastrous impact26. In expansion to
the death toll, the significant outcomes of concoction catastrophes remember to sway
for domesticated animals, greenery/fauna, nature (air, soil, and water) and misfortunes to industry27. A little mishap happening at the nearby level might be an earlier
cautioning sign for looming and the catastrophe. Compound catastrophe, through
low in recurrence, can possibly cause noteworthy prompt or long haul damage9.
Frequency and seriousness of synthetic calamities have expanded in the most-recent
couple of years [5].
In addition to loss of human life and property during chemical disaster, the dire
consequences include the impact on livestock, flora fauna, environment (air, water,
land) Chemical accidents depending upon the number of casualties injuries damage
to property, and environment can be categorized as a major accident or a disaster. A
major accident is defined in environment protection act 1986, and disaster is defined
in disaster management act 2005.

2.1 Gas Sensor
Semiconductor-based gas sensor helps in detection of presence of gas in environment.
The MQ-6 sensor primarily used in detection of gases in industries as well as it has
home applications. SnO 2 metal oxide coated gas sensor is used for its sensitivity.
When Sno 2 gas sensor is heated at a threshold value, the oxygen on a crystal surface
gets absorbed with a negative charge. Sensor resistance to electric flow recognized
by the potential barrier in gas deoxidising atmosphere. There is a direct relationship
with the sensor resistance and barrier height.
2.2 LCD Screen
A 16 × 2 LCD display with green LED backlight. Each panel displays symbol in
a 5 × 7 pixel matrix. A 16 × 2 means it can display 16 symbols in a line and with
2 displays lines. It has a two registers, namely data register and command register.
Command register helps/register commands such as clear screen, shift line whereas
