Why Are Gas Detectors Important?
Gas detectors play a critical role in safeguarding lives and property by detecting potentially harmful gas leaks before they become hazardous. Whether in industrial settings, commercial kitchens, or residential areas using Liquefied Petroleum Gas (LPG) and Natural Gas (NG), having the right gas detection system in place is essential.
In this guide, we explore why gas detectors are important, how they work, and where they should be installed, helping businesses and homeowners stay compliant with safety regulations.
Types of Gas Detectors: Portable vs. Fixed
Gas detectors come in two primary forms, each serving a specific purpose:
1. Portable Gas Detectors
Portable gas detectors are used by technicians and engineers to monitor air quality in real-time when working in hazardous environments. They help detect gas leaks instantly and trigger an alarm to prevent potential disasters.
How Portable Gas Detectors Work:
Use Cases:
2. Fixed Gas Detectors
Fixed gas detectors are installed in locations that require continuous gas monitoring, such as commercial kitchens, industrial plants, gas storage rooms, and burner areas.
How Fixed Gas Detectors Work:
- Continuously monitor enclosed environments where gas leaks can accumulate.
- Triggers alarms and notifies security or maintenance teams when gas levels reach dangerous concentrations.
- Prevents explosions and health hazards by ensuring early detection.
Use Cases:
- Commercial kitchens and restaurants
- Industrial factories and manufacturing plants
- Gas storage facilities and boiler rooms
Installation Guidelines for Maximum Efficiency:
- Carried by technical personnel to ensure the workspace is safe before performing maintenance.
- Detects leaks in gas pipes by running a sensor along the pipeline.
- Alerts the user via buzzer and alarm in case of a gas leak.
- More reliable than traditional methods like using a naked flame or soapy water.
- Maintenance of industrial gas pipelines
- Safety inspections in confined spaces
- Emergency response for gas leaks
The effectiveness of fixed gas detectors depends on proper placement based on gas density:
- Natural Gas (NG): Lighter than air → Install 30cm below the ceiling.
- Liquefied Petroleum Gas (LPG): Heavier than air → Install 30cm above the floor.
Improper placement can render the detector ineffective since gas accumulates at different heights based on its specific gravity.
Understanding Lower Explosion Limit (LEL) and Why It Matters
One critical factor when choosing a gas detector is its LEL detection capability. LEL (Lower Explosion Limit) refers to the minimum gas concentration needed to ignite an explosion.
For example, Comet Integrated’s gas detectors have an LEL detection of 20%, meaning:
- If gas concentration reaches 20% of the explosive threshold, an alarm is triggered.
- This provides enough time to locate and stop the leak before a potential disaster occurs.
- At 100% LEL, even a small spark could ignite a massive explosion.
Industries in Malaysia That Require Gas Detectors
In Malaysia, gas safety is critical for multiple industries.
Here are key sectors that must have reliable gas detection systems:
Industrial & Manufacturing Plants
Factories that utilize combustible gases, chemicals, and solvents are at high risk of gas leaks, which can lead to explosions and poisoning.
Commercial Kitchens & Restaurants
Food businesses using LPG must install gas detectors to prevent kitchen fires and carbon monoxide poisoning.
Construction & Engineering
Workers dealing with underground gas pipes or confined spaces need portable gas detectors to ensure air quality before entering hazardous areas.
Oil & Gas Industry
Petroleum refineries and gas processing plants require fixed gas detection systems to monitor volatile compounds like methane, propane, and hydrogen sulfide.
