Carbon Monoxide (CO) and Nitrogen Dioxide (NO2) as per National Building Code (NBC) are most commonly and widely used gas sensor for basement car park application to detect the accumulation and increase in CO and NO2 gas concentration exhausted from petrol and diesel powered vehicles and locomotives. Our main objective as per Global standards is the dilute the gas concertation by means on purging fresh air and simultaneously exhausting the accumulated toxic gases with the help of Supply and exhaust air fans along with the dual speed Impulse fans (JET air fans) to distribute the air across the entire basement area.
As per European Standard acc. To EN 50545-1 and as per ASHRAE Standard 62.1, CO and NO2 gas sensor are intended to control a ventilation system and/or to give an indication, alarm or any other signal to warn of a toxic hazard. These gases are generically called “target gases, apart from these gases LPG, CNG (CH4) and Hydrogen (H2) are the other probable gases entitled in the car park basement application from LPG, CNG powered up vehicles along with latest battery operated/hydrogen fuel cell/hybrid technology vehicles which are highly flammable/combustible in nature and can result in a catastrophic disaster if not detected/identified at the early stages for critical life safety and asset protection which could also become the main source of fire.
For a futuristic Visionary Basement ventilation car park solution, we should adopt the following gas type such as CO, NO2, LPG, HC (CNG and H2) gases along with smart digital control system where the Gas Detectors shall be connected in a daisy loop fashion as shown below:
Here the traceability of the gas sensors and identification of the fault error signals becomes very easy compared to the conventional method of direct coupling of analog signal from each gas sensor making the system more complex, bulky and expensive.
Australian standard AS 1668.2-2012 and Building Code Australia Section “J” indicates that the ventilation of the parking structures should be continuous, 24/7. However, by ventilating only when the sensors indicate a requirement, energy can be conserved both from reduced fan operation and also from any related heating or cooling costs and CO gas radical’s detection for enhanced Very Early Fire Detection
The selection of CO sensor being the most common gas found in car park basement application also plays a vital role to achieve the energy saving and make the entire system more efficient and reliable with linear variation to detect not only just CO gas but to also detect enhanced CO gas radicals having detection capability for very early smouldering fire and smoke detection (product of gas radicals generated due to products of combustion fire)

Benefits of CO Monitoring:
The very early sign in coal handling/processing plant fire is liberation of gas radicals (CO predominant). The idea is to detect the presence of this CO gas radical for very early fire prevention. By the time smoke is generated and detected it is already too late. A typical CO monitoring system for detection of products of combustion fires or spontaneous combustion of coal fires can warn potential fire two days in advance then flame is present or detected. By installing an effective CO and CH4 monitoring system, coal based power stations can benefit in the following ways:
Reduced insurance premiums
Better safety to plant and personals
Reduced down time
Prevention of loss of resources
Save time and money.
Why CO monitoring? :
Coal contains moisture which when liberated, coal gets oxidised, generating both heat and carbon monoxide. This heat when builds-up has the potential of creating spontaneous combustion of coal fires.
Coal is extremely friable and can be easily crumbled or pulverised. Further coal also generates coal dust needing extra preventive measures like proper maintenance of stockpiles, guarding against accumulations of coal in the fuel-handling system, compaction of stockpiles, cleaning spills and washing float dust. The most effective programme for fire-prevention would be to have Carbon Monoxide Monitoring and Control System
CO Monitoring Installation Aspects:
There will always be some safe background CO levels in coal handling or processing plants under normal operating conditions. These CO levels will rise during coal loading, handling and will again settle to normal levels once loading is finished and ventilation fans are running. It is important to find out the normal background CO levels by installing CO data-loggers and observing the CO generation trends under normal operating conditions of the plant. A typical CO level of 50 ppm of CO is normally present in background levels when coal is being handled, moved or transported. Based on these normal background CO levels the sizing/selection of the CO system (range etc) and alarm set points need to be undertaken.
Location of Sensors:
In general, it is wise practice to locate an adequate number of sensors at strategic locations based on knowledge of the potentials for ignition. When considering belt fires, sensors should be located in close proximity to drives, tail pieces, and main rollers.
When coal is the issue, any location where accumulation of coal dust or bulk quantities is likely or expected should be considered. These include belt transfers, crushers, dust collection systems, and storage bins (silos, bunkers, etc.). System Approach:
A typical system may consist of number of CO (range: 0-300, 500 or upto 1000 ppm) and or CH4 (range: 0-100% LEL) gas sensor/transmitters installed remotely at strategic potentially risky areas. The 4-20 mA output coming from these sensor/transmitters can be connected to a multi-channel gas controller which can handle from 2 to upto 96 remote sensor/transmitters. When CO concentration levels rise beyond the set limit (say above 100 ppm, depending on safe background levels), the built in relay contacts will automatically generate audio-visual alarm for plant supervisor to take corrective measure (ventilation fans, mains shut-off etc).
