INFORMATION
We extended our deepest condolesences to a victim.
A victim had fatal damage on his head due to explosion.
Jennie Runevitch, WTHR reporter said that victim as 48-year-old Jim Gibson, died of blunt force trauma to his head due to multiple skull fractures.
and
According to OSHA and the U.S. Department of Labor, the plant has been fined twice for violations in the past ten years in 2009 and 2004.
The Marion plant was ranked at the very bottom of GM for safety in terms of lost workdays and near-miss accidents.

[NOTE]
Overpressure is one of the key parameters to estimate severity to the body.
Metal stumping factory in General Motors, Indiana USA, was exploded and one person killed due to chlorine related chemicals etc. July 1, 2014
We extend our deepest condolences to a victim and his/her family.
Some media said that chlorine chemical was Chlorine Dioxides.
Please review your manufacturing processes to avoid any repetition.
- HS-TECH ENGINEERING is able to simulate explosion in a confined or semi-confined sapace, using fluidyn VENTEX, a 3D simulation software.

Characteristics of Chlorine Dioxide from Source A
Chlorine Dioxide is a powerful OXIDIZER and EXPLOSIVES on contact with CARBON MONOOXIDE, HYDROCARBONS, AMINES, MERCURY, ORGANUC MATERIALS, POTASSIUM HYDROXIDE, PHOSPHORUS, CHLORINE, SULFUR, HEAT, METALS and ALCOHOLS.
Chlorine Dioxide is sensitive to SHOCK and FRICTION and unstable in LIGHT and SUNLIGHT.
Storage of Chlorine Dioxide from Source B
Fiberglass Reinforced vinyl ester Plastic (FRP) or High Density Linear Polyethylene (HDLPE) tanks with no internal insulation or heat probes are recommended for bulk storage of 25 to 38 percent solution sodium chlorite.
Storage and chlorine dioxide systems typically include the following;
- Avoid storage and handling of combustible or reactive materials, such as acids or organic materials, in the sodium chlorite area.
- Inert material should be used in contact with the strong oxidizing and/or acid solutions involved in chlorine dioxide systems.
- Chlorine dioxide solution concentrations below about 10 g/L will not produce sufficiently high vapor pressures to present an explosion hazard under most ambient conditions of temperature and pressure.
- Adequate ventilation and air monitoring.
- Air contact with chlorine dioxide solutions should be controlled to limit the potential for explosive concentrations possibly building up within the generator.
- Chlorine dioxide concentrations in air higher than 8 to 10 percent volume should be avoided. Two methods can be applied: operation under vacuum or storage under higher positive pressure (45 to 75 psig) to prevent buildup of gas-phase ClO2 in the head space. Bulk storage (batch) tanks containing ClO2 should be suitably vented to atmosphere.

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.
[1] NIOSH Pocket guide to Chemical Hazards [http://www.cdc.gov/niosh/npg/]
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?
[Our Solution]
We propose to use Real Time Dispersion Simulation Method in identifying
critical area in your site. Please visit the web site at;

RISK COMMUNICATION SEMINAR for INDUSTRIAL CHEMICALS was held on June 20th at Interchage 21 Buiding, Bangkok
Risk communication was a key item for Pollutant Release/ Transfer and Register (PRTR) system and it is a good chance for pollutant generators to review their production lines drastically to reduce input materials and to reduce pollutants from the end of pipes.
PRTR initiatives will be a chance to accelrate competitiveness of Thai industries.
HS-TECH ENGINEERING would like to take a role as a Thai local provider
not only for EHS (Environment, Health and Safety) burden mitigation
solution but also for explosion/fire evaluation methods as well as
productivity enhancement solution provider in keeping strong relationships
with various sectors.

A gas (sulphur dioxide, SO2 etc.) leak and explosion caused fire from IRPC, Rayong Thailand at around 18:00 in June 9th 2014.
Fire broken out at IRPC's combined gas and oil plant.

HS-TECH ENGINEERING is able to evaluate explosion/fire and leakage risks, caused by petro-chemical industries, using 3D software 'fluidyn-ASSESS-RISK [1] ' in collaboration with fluidyn.
You might cut down on damage insurance fee drastically by evaluating risks with fluidyn-ASSEE RISK software.

fluidyn-ASSESS-RISK is a software tool for the analysis of accident scenarios on industrial sites. The software uses the latest UFIP(French Union of Petroleum Industries) risk assessment methodology (Blue Book) for petrochemical refineries to analyse all possible accidental scenarios on petrochemical sites by analytical and empirical methods. This UFIP methodology has been validated by INERIS (French National Institute for Environment and Risks).
fluidyn-ASSESS-RISK is a software developed by TRANSOFT International in collaboration with the UFIP (French Union of Petroleum Industries), a major organisation of French petroleum industry.
