Toxic Gas Detection

Toxic gas such as ammonia or hydrogen sulfide can be present in a number of industries, increasing the possibility of compromising employee’s overall health. Too much of a certain gas can also affect the performance of equipment in the area as well. Toxic gas detection systems monitor the presence of gases in a specified area and alert personnel when they reach dangerous levels.

Toxic gas detection systems are commonly placed in areas with the potential of leakage and pose an immediate danger to people and equipment in that range. The gas monitors used to identify toxic and oxygen deficiencies work by measuring the concentration of the specific gas you wish to locate. Users have the option of having multiple single gas detection systems or implementing a system that can detect more than one gas (some systems can measure up to four gases). Detectors are programmed with pre-set levels, depending on the type of gas, to measure the concentration of the gas. A senor within the arrangement, four different types currently exist, is the piece within the device measuring the concentration in ambient air. When the concentration of the gas goes beyond the range programmed in the system, an alarm will sound to notify those in the area that something is wrong. There is also an option to have readings sent via digital signals through a wireless network that notify those in a control room a well.

Toxic gas detectors can be found in industries such as oil and gas, medical facilities, power plants. food and beverage, and more. The type of toxic gas detector you select depends on the needs of your industry. To select the right system for your needs, there are five things to keep in mind: reliability, features & useability, reading sensitivity & accuracy, alarm response time, and sensitivity to environmental factors. Reliability assists in gas detection operations because it supports workers by providing little malfunction lapse and longer product life. Features and useability give workers the ability to easily use the system, install, and perform calibrations as needed. Additional features such as data recording requirements and wireless capabilities are also a plus. Reading sensitivity and accuracy are important because some systems require a higher level of sensitivity than others. This means your detection system can register readings within the required range with hardly any standard deviation. Alarm response times aid workers with their response when a leak does occur in the area. Every second counts to ensure safety, as some toxic gases can result in moderate side effects in a very short period. Having enough time to react and correct the issue is beneficial. Sensitivity to environmental factors is one aspect with little thought. Heat, moisture, humidity, and other environmental conditions within the workspace can affect readings from the sensor, leading to false readings or delay response time when a leak occurs.
