A gas detector is a device that detects the presence of gases in an area, often as part of a safety system.
Gas leak detection is the process of identifying potentially hazardous gas leaks by sensors. These sensors usually employ an audible alarm to alert people when a dangerous gas has been detected. Exposure to toxic gases can also occur in operations such as painting, fumigation, fuel filling, construction, excavation of contaminated soils, landfill operations, entering confined spaces, etc. Common sensors include combustible gas sensors, photoionization detectors, infrared point sensors, ultrasonic sensors, electrochemical gas sensors, and semiconductor sensors. More recently, infrared imaging sensors have come into use.
As detectors measure a specified gas concentration, the sensor response serves as the reference point or scale. When the sensors response surpasses a certain pre-set level, an alarm will activate to warn the user. There are various types of detectors available and the majority serves the same function: to monitor and warn of a dangerous gas level. However, when considering what type of detector to install, it is helpful to consider the different sensor technologies.
Benefits of Gas Detection System
- The Types of Gas Hazards
You will find gas hazards in three different forms: toxicity, oxygen depletion and explosive gases. If you have oxygen depletion, it will occur in high gas concentrations, and it will be found in areas other than ambient air. While you may only have non-explosive or non-toxic gas, it can still displace the ambient air and reduce the oxygen levels. This can still make it unsafe for your operator to enter the area.
- Continuous Monitoring
The benefit of a gas detection system is that it will provide you with 24/7 monitoring, and you can watch all areas. When you can detect hazardous gases in advance, you will reduce the safety risks on the job, and many times, you will satisfy the criteria on your insurance policy.
- Watch the Expenses
With a gas detection system, you can reduce the amount of time it takes for an assessment because you do not have to manually monitor the potential for explosion in the area. This will cut down on the number of hours spent over labor, and ultimately, that means saving money on the expenses.
- Strong Shield
When you have a gas detection system, you can monitor the amount of gases in your environment. Because of this, you can tell when there is a higher chance of poisoning, explosion, fire or asphyxiation.
