Most companies, factories, and industrial businesses, such as mining, oil rig, etc, equip themselves with safety equipments, such as fire extinguishers or gas detectors. These detectors prevent the possibility of gas leak, fire, even explosion. There are two main types of detectors: portable and fixed one.
In the old days, the gas detectors were only designed to detect one type of gas, but today’s detectors are designed to detect several different gases at the same time. How do they work? Well, these detectors are set in certain standardized gas levels. They also come with sensor response to serve as the reference level. When the sensor detect the exceed gas amount in the standardized level, it will automatically activate the alarm to produce loud noise and flashing bright light as the warning sign. By this way, people will know there’s something wrong and immediately stop whatever work they’re doing and also leave the area fast.
There are two types of gas detection equipments: the combustible gas detector or the toxic gas detector. They also use different technology of catalytic and infrared sensors. As the name suggests, the combustible gas detector mainly reacts to easily burned gas. The detector then gives warning whenever these easily burned gases are within reach in dangerous amount and level. For the toxic gas detector, it also reacts to toxic and poisonous gas. These devices mostly installed everywhere because the chance of toxic gas leak is very much dangerous and life-threatening. When there are no such devices around, people are prone to dangerous working condition, and nobody wants that.
