Today, we’ll walk you through selecting the appropriate combustible gas detectors for your requirements. We will discuss the main elements to consider, the several kinds of detectors accessible, and the reasons this choice could be among the most crucial regarding safety. By the end of this, you will know exactly what to search for to maintain a compliant, safe, free from needless risk workplace.
What are Combustible Gases?
Combustible gases, such as methane, propane, butane, and hydrogen, are invisible, silent, and shockingly lethal. They could be present in your workplace at any time. Explosions can be easily triggered by a small spark from a broken wire, a thoughtlessly thrown cigarette, or even static electricity. The damage caused by these explosions extends beyond physical harm; companies can be ruined, lives lost, and the ripple effects can last for years. Here are brief explanations of why we all need to be aware of these gases:
- Methane: Methane is found in coal mines and oil platforms, so methane is extremely explosive when combined with air.
- Propane: Propane is safe for cooking and heating but can pose a lethal hazard in certain conditions.
- Hydrogen: Hydrogen is quite explosive and is used in industrial operations. Its tiny molecules can escape through microscopic gaps, making detection difficult without the correct tools.
- Butane: Common in fuel, butane may start fires immediately when combined with air in enclosed areas.
These gases don’t differentiate—they threaten any operation handling fuel, chemicals, or industrial waste. Whether discussing large-scale industries or smaller setups, these dangers remain the same.
Industrial accidents caused by gas leaks are not rare headlines; they’re common occurrences. According to Safe Work Australia, gas-related incidents threaten workers’ safety, highlighting the need for proper detection measures. When it comes to ignition, all it takes is a flicker, a misplaced tool, or even a slight temperature change to set off a chain reaction.
That’s why we need to be proactive. Installing a combustible gas detector is not just about compliance—it’s about taking control before the situation spirals out of our hands.
Types of Combustible Gas Detectors You Need to Know
- Catalytic Detectors
Catalytic detectors have been around for some time and are excellent at identifying flammable gases in oxygen-rich surroundings. The detector detects heat generated from a reaction between gas and the sensor. But here’s the catch—these devices need oxygen to function properly. In low-oxygen environments, their accuracy drops like a stone.
- Infrared (IR) Detectors
These are the sharp shooters. IR detectors use light to measure gas concentrations differently, making them suitable for environments with limited oxygen or where catalytic sensors are ineffective. They’re not affected by toxins and have a longer lifespan, but of course, you’ll pay more for the luxury of that reliability.
- Fixed Detectors
These stay in one place, continuously monitoring a specific area for gas levels. Consider them sentinels’ day and night, watching over your most sensitive areas. They are perfect for monitoring high-risk areas, including chemical manufacturers, refineries, and fuel storage. Once configured, they constantly provide real-time data to your control system, ready to set off the alarm upon the first smell of a threat.
- Portable Detectors
If fixed detectors are your stationary guards, portable detectors are the ones that travel with you. These handheld devices are essential for anyone working in high-risk environments who needs to move around. They’re small, lightweight, and designed to keep your team safe as they move from site to site, checking areas that may not be constantly monitored.
The Right Detector for the Right Job
You need a detector that matches your environment. Not all gases act the same way, nor should your detection systems. Here’s a quick recap:
- Catalytic for every day, oxygen-rich environments.
- Infrared for tougher, low-oxygen areas or where toxins could interfere with other sensors.
- Fixed detectors for constant monitoring in set locations.
- Portable detectors to keep your crew safe wherever they go.
Still unsure? That’s where our expertise comes in.

The No-Nonsense Guide to Choosing the Right Detector
The first step before buying a detector is understanding the battlefield. Ask yourself: What are we dealing with here?
- What gases are present? Whether it’s methane, propane, or hydrogen, different gases have different behaviours and risks.
- What’s the airflow like? Are we talking about a confined space where gas can quickly build up or an open area where it can disperse? These factors change everything.
- What’s the temperature? Some detectors won’t perform well under extreme conditions. If you’re working in cold or blistering heat, you’ll need something robust to handle.
Knowing your surroundings is the basis rather than only the initial step. If you get this incorrect, nothing else counts.
Sensitivity and Accuracy: Too Much or Too Little Can Kill
Let us now focus on sensitivity. You want a detector that misses the actual threat, not one that’s so sensitive, it’s always a crying wolf. It’s a balancing act.
- High Sensitivity: Excellent for situations where gas levels can rise rapidly but might cause more false alarms.
- Lower Sensitivity: You run the possibility of not capturing harmful levels in time, even if false alarms may be lowered.
Here, accuracy is vital. Detectors who know the difference between a minor leak that requires attention, and a full-on emergency are not only beeped at the first indication of problems. We recommend establishing reasonable thresholds based on your business rules and circumstances so that your detector works for you rather than against you.
Making the Call: Do Your Research
When it comes down to it, picking the right detector is about doing the legwork. Here’s a quick checklist to help you stay on track:
- Match the Detector to the Gas: Methane? Propane? Hydrogen? Ensure your detector is built to handle the specific gases in your workspace.
- Consider the Environment: Is it hot, cold, dusty, or damp? Choose a detector that can handle the local conditions.
- Think Long-Term: Don’t just settle for compliance. Invest in detectors that can grow with your business and adapt to future regulations.
We don’t believe in generic solutions. We offer tailored recommendations that match your environment’s specific needs. We assess your situation, examine the gases involved, and help you implement the right mix of technology to stay safe today and tomorrow.
4 Simple Steps to Extend Lifespan
Want to get the most out of your investment? Here are some simple ways to prolong the lifespan of your gas detectors:
- Keep sensors clean: Dirt and dust can clog up sensors, leading to inaccurate readings. Regular cleaning can help maintain accuracy.
- Store properly: When detectors aren’t used, store them in a clean, dry place. Extreme temperatures or wetness can shorten the lifetime of anything.
- Replace batteries: Sounds obvious, but low power can lead to faulty operation. Make sure you’re regularly checking and replacing batteries where needed.
- Schedule regular checks: Set up a calendar reminder for maintenance and calibration. Don’t rely on memory or assume someone else will handle it.
We have said that and want to reiterate that maintenance is not optional. You have to prioritise your gas detection system if you want it to guard your people and property. It’s as straightforward as that.
