Carbon Dioxide Detection
WHAT IS CARBON DIOXIDE?
Carbon dioxide (CO2) is a gas which occurs naturally in the Earth’s atmosphere at a rate of 400 parts per million (ppm). It is colourless, odourless and non-flammable.
CO2 is used in a wide range of industries:
it is used to carbonate soft drinks and alcoholic beverages,
it is a primary ingredient in fire extinguishers
it is used to decaffeinate coffee and clean clothes
it is used to promote growth in fruit and vegetables
it is used as a coolant gas in power stations
it is used to create dry ice
carbon dioxide can also be generated by certain products, for example, when timber is held in a confined space, it undergoes oxidation which causes CO2 to be produced
The level of CO2 normally in the atmosphere is harmless, but an increase of levels of the gas in a working or home environment can have serious health effects. Some organisations have set long and short term exposure limits for working, and this legislation varies globally.
OSHA (Occupational Safety and Health Administration) have set an exposure limit of 5,000ppm over an eight-hour period, and 30,000ppm over a 10-minute period, whilst the European standard EH40 has set a short-term 15-minute exposure limit of 15,000ppm.
THE BENEFITS OF CARBON DIOXIDE GAS DETECTION
As CO2 has no taste or smell, it can be hard to detect. This is why CO2 monitors are so important, and a workplace risk assessment may suggest that gas detectors are installed.
Analox offer a wide range of carbon dioxide monitors – from portable monitors like the Aspida and the ACG+ to fixed monitors like the Ax60+.
As CO2 is heavier than air, it is recommended that fixed carbon dioxide detectors are not mounted at head height – for example, we recommend that the Ax60 is wall-mounted 450mm off the ground and the repeater unit is placed at head height at the entrance to the room.
