subject: Make Sure You Have Gas Detection Systems [print this page] Gas detectors are widely used in the home and work place and are manufactured to detect two main types of gas : ammonia and combustible. Although gas is so widely, and largely safely, used its main component is highly flammable methane. Detectors are used to alert occupants of buildings to hazardous leaks and provide early warning of the risk of fire and explosion by sensing the immediate or background atmosphere. The following detectors are suited to different environments and should be used according to individual requirements.
Portable detectors are handheld devices that can be used to test confined spaces. It traces leaks and gives a warning. A range of detectors are available for various gasses which could leaks of methane, carbon monoxide and dioxide. Single unit multi gas emissions analysers are also available; ideal for use in boiler houses.
Fixed detectors are wall mounted to offer permanent, built in protection. Such systems are ideally placed next to boilers and other devices which use natural gas. Depending upon the model they can give off a combination of sound and light alerts. They also feature early warning systems to quickly raise awareness of small or intermittent leaks.
Cells are electrochemical sensors, used in the detection of carbon monoxide, chlorine and nitrogen oxide. They are capable or detecting not only the presence, but concentration by measuring for electrodes and the current of the gas. Electrodes on the device send signals via electric current when one of these gasses is detected. For this reason, they are highly sensitive.
In a similar way to home smoke detectors, all gas detectors are battery operated, to maximise reliability and continually provide protection. These life saving systems are widely available at DIY, home improvement and trade outlets for reasonable prices. They provide piece of mind in any non-industrious environment and vitally important, early notice, when everyday devices mal-function.
