GAS DETECTION
Monitoring your surroundings for hazardous gases is an important part of workplace safety. Many gases, including carbon monoxide, can be difficult to detect without gas detector. You can’t see, smell, or taste these gases, so you will need to use a gas detector to make sure you and your team have access to clean air on the job. The gas detector will alert you and your team if hazardous gases are present in the air.
What Is Gas Detection?
Gas detection is the idea of monitoring your workplace or surroundings for hazardous gases, such as:
- Carbon monoxide
- Chlorine
- Nitrogen dioxide
- overall oxygen levels
Exposure to these gases could lead to severe illness or even death. By monitoring your workplace, you and your employees don’t have to worry about breathing in harmful chemicals and gases. If the air quality changes, the gas detector will send out an alert, so you can respond immediately.
How Are Gas Detectors Used?
Gas detectors are often used by:
- First responders
- Utility crews
- Firefighters
- Maintenance professionals
- Other individuals that may come into contact with hazardous gases
This equipment can either be worn on your person in what’s known as “the breathing zone,” near your nose and mouth, or you can set up a monitor in the corner of the room to make sure the air is safe to breathe. When wearing a gas detector, keep it near your nose and mouth to make sure you record the most accurate levels.
In addition to safeguarding your employees, you can also use gas detection systems to log the overall safety of your workplace over time. Keep a record of all gas leaks and other possible workplace hazards, so you can address these issues as soon as possible.
What Is the Best Gas Detector?
There are many different gas monitors for you to choose from. You need to use a gas monitor that’s designed to detect your target gas. Use a Portable Gas Sensor to protect yourself from multiple gases at once.
It may be difficult to see or hear on the job, so it’s best to find a gas detector that comes with multiple alarm settings. Ideally, the alarm will vibrate, flash a light, and emit an audible tone when hazardous gases are present, so your team can quickly keep track of oxygen levels without having to zero in on specific readings.
Having a gas monitor that’s connected to the internet will improve the overall safety of your workplace as well. If a leak occurs, the monitor should alert the person wearing the device as well as those monitoring your workplace from afar. The safety manager can then share this information with other team members, thus limiting their chances of exposure.
How Do Gas Detectors Work?
Gas detectors generally use either a catalytic bead or a non-dispersive infrared (NDIR) sensor.
Combustible gas mixtures start burning when they reach their ignition temperature. Gas monitors with catalytic bead sensors come with metal oxides that speed up the oxidation process, so these monitors can detect and report the presence of hazards gases as soon as possible. These monitors are not gas specific and are seen as highly reliable.
Detectors that use non-dispersive infrared (NDIR) gas sensors will detect the gas molecules’ absorption of infrared energy by the bonds of dissimilar atoms. Non-dispersive IR sensors measure gases at a specific range of wavelengths associated with a particular gas.
When these devices detect hazardous gases, the sensor output will display a reading of the specific gas, including the level of exposure.
How Do You Recalibrate a Gas Detector?
Recalibrating your gas monitor means exposing it to the target gas. You will need to use a cylinder of your target gas. Make sure it has not yet expired. Start by zeroing the gas detector and then insert the calibration gas into the device. The device should respond to the calibration gas as if there were a gas leak. Make sure the readings on the device match the contents of the calibration gas.
You can also automatically recalibrate your monitors overnight by keeping them in a docking station. Every monitor will be good to go at the start of each shift.
