Gas Detection System
Gas Detection System
The Gas Detection System with the gas detectors which have been developed and enhanced through years of research and development, play an important role in specialty gas and bulk gas application in many industries that utilises gases for operation, gas leak detection and gas leak isolations.
YHWH SHAMMAH CREATIONS as one of the main gas detection system design and solution provider, provides comprehensive gas detection system design based on the application of our clients.
Basic criteria which are given much consideration in the gas detection system design are:
- sensor technology selection
- design and review gas detection system (coverage, number of devices, serviceability, asset lifecycle and etc.)
- supply, install and testing & commissioning.
- periodic calibration
- predictive maintenance and asset lifecycle management.

Oxygen (O2)
Oxygen is vital to life on our planet. It’s also essential for a wide range of industries that support daily life, including steel manufacturing, chemicals, paper manufacturing, and medicine. However, it also poses certain hazards. Here we’ll present some potentially life-saving facts about oxygen.
Composition of air
Accounting for approximately 21 % of Earth’s atmosphere, oxygen is essential for humans and other creatures.
Definition of anoxia (oxygen deficiency)
Anoxia is the condition in which the concentration of oxygen in the air is below 18 %.
# Main causes of oxygen deficiency
- Oxygen consumption
Oxidation of metals, ore, and subsoil iron, human respiration, respiration by cereals, fruits, vegetables, and timber, oxidation of paints and solvents
- Influx of inert gases or coolants
Influx of N2 gas (including liquid nitrogen), argon gas, or CO2, influx or buildup of coolants such as fluorocarbons
- Release of combustible gases
Release of methane gas during excavation, gas leaks from fuel gas pipes.
# Excessive oxygen
Higher oxygen concentrations will increase the size and temperature of flames, lower the ignition temperature of combustible materials, and increase combustion speed. All this results in an increased risk of fire.
For humans, continuous inhalation of high oxygen concentrations can lead to convulsions, loss of consciousness, and, in the worst case, death.
Toxic gases (CO, H2S etc.)
Gases that are harmful to humans in the event of inhalation or exposure are called toxic gases. While these gases are dangerous, a wide range of industries depend on their characteristics. Stringent legal standards regulate the manufacture, transportation, use, and management of gases. Here, we’ll present information on the types and characteristics of toxic gases, which may prove useful in the unlikely event of an accident or disaster.
Definition of toxic gas
While the definition of toxic gas was revised through revision of the ministerial ordinance, according to the Exemplified standards relating to the Regulation on Safety of General High-Pressure Gas , the alarm setpoints for gas leak detection and alarm equipment remain unchanged and must be threshold limit values or lower.
Threshold limit value (TLV) In accordance with ACGIH (American Conference of Government Industrial Hygienists) recommended values
Workplace air concentrations below which it has been determined most workers suffer no ill effects
- TWA (time weighted average: threshold limit value for workers normally working eight hours a day, 40 hours per week)
- STEL (short-term exposure limit: value that the 15-minute mean cannot exceed)
- C (ceiling value: upper value that cannot be exceeded)
