The recent tragic gas explosions in Chattogram and Cumilla have left us with heavy hearts. Whether it is a piped natural gas line or an LPG cylinder, the loss of life and property is a stark reminder that safety should never be an afterthought. At SmartX BD, we believe that selling a device is not enough; ensuring you know how to use it correctly to save lives is our true mission.
⚠️ Gas leakage is silent.
⚠️ Gas accumulation is invisible.
⚠️ Explosion risk builds quietly.
✅ But in many cases accidents are preventable.
🛑 This is not a promotional post.
🛡️ This is a safety awareness message from SmartX BD.
🔥 Two Types of Common Household Gas Risks
1️⃣ Line Gas (Natural Gas / Methane)
Used in many buildings through pipeline connection.
🚨 Important fact:
⚠️Natural gas (methane) is lighter than air.
⬆️ If leaked, it rises upward and accumulates near the ceiling.
2️⃣ LPG (Liquefied Petroleum Gas – Cylinder Gas)
Common in apartments and homes using cylinders.
🚨 Important fact:
⚠️ LPG is heavier than air.
⬇️ If leaked, it sinks downward and accumulates near the floor level.
This difference is extremely important when installing a gas detector.
📍 Correct Positioning of Gas Leak Detector
Proper installation is critical.
✅ For Line Gas (Natural Gas / Methane)
👉 Install 15–30 cm below ceiling
👉 At least 30 cm away from corners
👉 1.5 to 2 meters away from stove
👉 Around 50 cm above burner height
👉 Avoid direct airflow, windows, and exhaust fans
Because leaked methane rises upward.
✅ For LPG Cylinder Gas
👉 Install 15–30 cm above floor
👉 At least 30 cm away from corners
👉 1.5 to 2 meters from cylinder or stove
👉 Avoid airflow areas
Because LPG settles near the ground.
Incorrect positioning = delayed or no detection.
💡 What Is %LEL?
👉 LEL = Lower Explosive Limit
👉 Every combustible gas has a minimum concentration level in air where it can ignite.
For example:
If gas concentration reaches a certain percentage in the air, and there is a spark, it can explode.
6% LEL means:
The gas concentration has reached 6% of the minimum explosive level.
It does NOT mean explosion will immediately happen.
It means: ⚠️ Gas concentration is building and becoming dangerous.
SmartX BD sells gas detectors which trigger alarm at:
🔔 6% LEL (±3%) — That means it alerts you very early, before reaching a highly dangerous explosive concentration.
🛡️ This early warning can save lives.
🚨 Important Reality: Ventilated Gas is Not Explosion Risk
If gas leaks but is properly ventilated and does NOT accumulate in a closed space, it will not reach explosive concentration.
🚨 Gas explosion risk happens when:
❗ Leakage occurs
❗ Room is closed
❗ Gas accumulates
❗ No early detection
❗ Spark occurs
That is when disaster happens.
A gas detector is meant to detect accumulation risk, not minor ventilated smell.
🔔 What To Do If Alarm Triggers?
🚨 If your gas detector alarms:
❗ Do NOT switch electrical devices on/off
❗ Do NOT use matches or lighters
❗ Open doors and windows immediately
❗ Turn off gas supply
❗ Leave the area if smell is strong
If you are outside home, WiFi-enabled gas detectors send alert via app, allowing you to act immediately.
🛑 Gas Leak Detector vs Cylinder Explosion
Important clarification:
⚠️ Gas detectors detect:
✔ Gas leakage accumulation
✔ Explosion risk from combustible gas
⚠️ They do NOT prevent:
❌ Cylinder structural explosion due to cylinder failure
🛡️ Cylinder safety depends on:
✔ Manufacturer standards
✔ Expiry validation
✔ Proper storage
✔ Regular inspection
Modern buildings keeping LPG cylinders on ground floor is a very good safety measure. That storage area should also have gas detectors installed.
📱 Smart Gas Detectors Are Not New
Gas detector alarms are available in the market for years. But awareness is the key.
Buying one after news headlines without understanding:
🎯 How it works
🎯 Where to install
🎯 What LEL means
🎯 What to do during alarm
— makes it less effective.
Safety device + knowledge = protection.
🏢 SmartX BD’s Role
For many years, SmartX BD has been supplying:
✔ WiFi-based combustible gas detectors
✔ App alert supported (Tuya / Smart Life)
✔ Sound alarm + mobile notification
✔ Early detection at 6% LEL
Models include:
✔ Plug-and-play 3-pin UK type (85–250V AC)
✔ Type-C powered model with display & heat detection
But more important than product is awareness. Because safety starts with knowledge.
Choosing the Right Safety: Gas Detector Price in Bangladesh
At SmartX BD, we believe safety should be accessible to every household. When looking at the gas detector price in Bangladesh, you will find various options. Our curated models focus on WiFi connectivity and high sensitivity:
- Standard WiFi Gas Sniffer (3-Pin Plug): Price ৳1,650. It is the most popular choice for apartment residents.
- Premium LCD Display & Heat Sensor Model: Price ৳2,800 . This is recommended for those who want real-time LEL visibility and fire (heat) detection in one device.
Note: Prices may vary based on ongoing safety campaigns and seasonal discounts.
