Know About The Ins and Outs of LPG Gas Detection in Factory

LPG or liquified petroleum gas, is a versatile and globally used fuel that consists of butane and propane. It is a flammable hydrocarbon gas liquefied by putting pressure for ease of storage, use and transport. LPG is widely derived from petroleum refining and gas processing. Its prevalent use in factories is for heating applications, industrial processes, power generation, catering and cooking facilities, forklifts and material handling, and so on. 

In LPG factories as well as homes and business areas safety plays a huge role and it is necessary that better safety systems are to be put in places like these. We as the leader in the industry are creating awareness through our LPG gas agency dealership across the nation. Hence, based on their insights we have created a blog that focuses on modifying the existing safety model that has been implemented in industries. One of the measures that should be taken to avoid the danger linked with gas leakage is to install a gas leakage detector at vulnerable locations. 

The Hidden Danger of LPG

LPG may leak as a liquid or a gas. If the liquid leaks then it can quickly evaporate and form a huge cloud of gas which will drop to the ground, as the evaporated gas is heavier than air. On the other hand, if it leaks like a gas it can spread to a large distance, splitting themselves on the ground as well, as a result, they can collect in drains or basements. The most dangerous part of this gas leakage occurrence is when it meets a source of ignition it can burn or explode. 

This dangerous occurrence can lead to

  • Asphyxiation Hazard 
  • Inhalation Risks 
  • Skin and eye irritation
  • Leaks and gas buildups 
  • Environmental Impact 
  • Inadequate ventilation 
  • Corrosion and material damage 

To avoid these dangerous situations it is essential to install gas detectors in the factory area. 

A gas detector is a device that helps the experts to detect any presence of gases in a space. Gas detector signals through a sound more like an alarm to operators in the area where the leak is occurring, giving them the time to fix or leave the scene. This device is essential as there are gases that can cause harm to humans and animals that are not familiar to human or animal noses. 

Why gas detection is Crucial? 

Toxic Gas Monitoring

Gas detection devices are mainly used to observe indoor and outdoor air for toxic gases such as carbon monoxide (CO), Sulphur dioxide (SO2), Nitrogen dioxide (NO2) and Hydrogen Sulphide (H2S). by continuously looking for these gases helps the experts and workers to protect human health and ensure the safety guidelines. 

Industrial Emissions Monitoring 

In factory settings, gas detection systems are placed to look at the emissions of pollutants into the atmosphere. This helps factories to maintain environmental compliance and safeguard from harmful gases from mixing into the air. 

Workplace Safety 

Gas detectors are important for making sure of the safety of the workers in the factory where exposure to harmful gases can happen. These devices offer early warnings of gas leaks to enable proper evacuation and prevent accidents or health issues by inhalation. 

Hazardous Material Handling 

Gas detectors are crucial in facilities where hazardous materials are sorted. They help in monitoring the presence of toxic gases that have the potential to get released during the transportation, and storage of these materials. 

Confines Spaces 

These gas detector devices are used to safeguard workers in contained spaces like tanks, tunnels or storage vessels where there is a possibility of gas buildup. These devices are therefore essential for letting know the presence of gases that can displace oxygen or are a health risk. 

Different Technologies for Gas Detection 

Catalytic Bead (CB)

The operating principle of Catalytic gas detectors shows their combustion for measuring combustible gases in air at lower explosive level concentrations. A heated catalyst which is a coated wire coil burns the selected gas. As the temperature of the wire rises, as well as its electrical resistance, a standard Wheatstone bridge circuit makes use of two-wire coil elements to transform the raw temperature change to alert the presence of combustible gas. 

Electrochemical (EC)

These detectors can be considered transducers that convert gas concentration to an electrical current. They make use of an electrolyte and electrodes for producing an electrochemical reaction while generating a current proportional to the gas concentration. Various cells develop for specific toxic gases like carbon monoxide, hydrogen sulfide etc. 

Point Infrared (PIR)

Infrared gas detectors make use of two wavelengths, one at the gas-absorbing which is termed “active” and the other at a wavelength not absorbed by the gas termed “reference”. In point IR detectors, the concentration of hydrocarbon gas is measured through the infrared absorption of an optical beam also known as an active beam. The second optical beam known as the reference goes through the same optical path as the active while containing radiation at a wavelength not absorbed by the gas. 

Open Path Infrared (OPIR)

This detector is similar to the principle of the point IR technology, except for the detection path where the distance of the IR beam is stretched to 100 meters. OPIR detectors can make use of a retro-reflector or different IR transmitters and receivers that are housed in different enclosures to look for a gas cloud in the IR beam path. 

Laser-Based Gas Detection Technology (ELDS)

The enhanced laser diode spectroscopy gas detector is an open-ath non-contacting way of detecting certain toxic gases. When a gas leak takes place the ELDS sensor’s laser optical technology recognizes and goes through the gas’s specific harmonic fingerprint. Some of the technologies give false alarms but in the case of ELDS detectors, it has a highly selective harmonic fingerprint technology. These detector’s sensors are also immune to sensor poisoning. 

Ultrasonic (UGLD)

When compared to traditional gas detectors that only focus on % LEL (lower explosive level), ultrasonic gas leakage detectors answer to the ultrasonic movie created by the pressure of a gas leak. This noise provides insight into the leak rate and establishes warning and alarm thresholds. Gas does not have to reach the sensing element as the detector “hears” the gas leak. 


There you go with the Ins and Outs of LPG Gas Detection in a Factory, and the awareness spread through this blog by the leading LPG gas agency- Shivgas. LPG is used in various industries for various reasons, but workers working there also can face gas leakage for which gas detectors are a must in factories. It can save lives. Being the leader in the LPG gas industry, working alongside the initiatives to set up gas detectors in places where it is necessary is our concern as well. Hence, we are doing our best to save lives and contribute more towards a greener planet.
