How to identify contaminated area with NH3 gas and how to
address critical situation, in case of a huge amount of NH3 gas leak?
Our Solution: Real Time Dispersion Simulation
[Back grounds]
Your site has already installed gas monitoring system which covers indoor and
outdoor area in case when toxic/flammable gases leak will be occurred.
The key device of detecting toxic/flammable gases are sensors. Most parts of
your drills might be mentioned the countermeasures on how to prevent from
accidents.
[Reguratory Status in Thailand]
Department of Industrial Works, The Ministry of Industry is considering
issuing a ministerial regulation that will mandate factories to acquire an
insurance covering 3rd party protection against various accidents.

[Detecting Devices]
You know that there’re so many kinds of sensors developed such as;
l Metal Oxide Based Gas Sensors,
l Capacitance Based Gas Sensors
l Acoustic Wave Based Gas Sensors
l Calorimetric Gas Sensors
l Optical gas sensors
l Electrochemical gas sensors
Some detectors are damaged when high concentration dose will be induced to
the detectors. Take example for Ammonia [1], typical electrochemical
ammonia detector will be able to detect only up to 100 - 300 ppm.
Photoionization detector (PID) might be a solution to solve this problem.

Time Weighted Average: 25ppm
Short term Exposure Limit: 35ppm
Immediate Danger to life and Health: 300ppm
Lower Explosive Limit: 15% (150,000ppm)

[Identify Affected Area in Your Site After Accidents]
How to identify contaminated area with NH3 gas and how to address critical
situation, in case of a huge amount of NH3 gas leak in concentration of above
300 ppm at your site, according to your emergency drills?
