If you are operating more than one fixed gas detector, it’s best to use what’s known as a gas detector controller to monitor all the gas readings and signals coming your way.
Most companies will install several fixed gas monitors throughout the work environment if there’s a chance their workers may be exposed to hazardous gases in different areas. The detectors will then transmit their findings to the gas detector controller. This is an integral part of the gas monitoring system. The controller is able to set off an alarm or signal other components (such as ventilation fans) to operate, so that managementof the work environment can be handled in a systematic way.
We sell several of RKI Beacon Fixed System r Controllers at PK Safety that can work with as little as two points and go up to eight points of gas detection. RKI Instruments makes some of the industry’s best and most reliable gas detection equipment. Since 1994, they have been helping workers stay safe in the field. Their equipment has been thoroughly tested to ensure that they hold up on the job. All RKI portable and fixed gas detectors come with a 3-year warranty to help you maintain your equipment over time. You can get everything you need to monitor your workplace for hazardous gases at PK Safety. Browse our selection of RKI gas detection equipment to find the right device for the task at hand.
How do gas monitors work?
Each gas sensor is designed to detect and measure the concentrations of a particular gas in the air, including oxygen, hydrogen sulfide, or carbon monoxide, and the lower explosive limit (LEL) of combustibles that could lead to a flash fire. Each device is fitted with a sensor that will create a chemical reaction when it comes into contact with the target gas. The device will then trigger an alarm, so the person can evacuate the area and protect themselves from exposure.
Hazardous gases can travel fast in the workplace, and safety managers need to be able to monitor gas levels throughout the work environment. The gas detector controller intercepts the signals coming from the fixed and portable gas monitors. Channel controllers will issue an alarm when one device detects high concentrations of a target gas, so the manager can take additional precautions to prevent exposure. The controller also reports the condition of the gas detectors, including whether they are on if they are connected to a power supply.
Individual gas monitors may relay the signal to the controller using a wired connection or wirelessly over the internet. The controller will then compile this information in real-time. It keeps your gas detectors connected, which allows you to respond to a potential gas leak quickly.
When should you use a gas monitor?
You should use a gas monitor when working in a confined space or an area with limited ventilation. The CDC defines a confined space as an environment unfit for human occupation with limited entrances and exits and poor airflow. This includes basements, utility tunnels, manholes, wells, and other underground spaces.
You should also use a gas detector when working with or near hazardous gases, including carbon monoxide, methane, and hydrogen sulfide. They are often used in the oil, gas, and fossil fuel industry. If you are monitoring your permanent workplace, use fixed gas monitors that stay in one location to monitor your surroundings. They stay on for months on end for continuous protection.
Portable gas monitors are often used when working in unfamiliar or unpredictable environments. For example, service crews and first responders will often wear gas detectors on their person when working in the field to detect for potential CO poisoning They run on batteries and need to be recharged at the end of each shift.
If you are managing or overseeing multiple gas detectors, you will need to use a multi-channel gas detector controller to keep track of the various gas readings. The device will compile this information into a single report, so that you can monitor your entire workplace from one location.
What is a multi-gas monitor?
Multi-gas detectors target all four major gases, including oxygen, carbon monoxide, hydrogen sulfide, and the LEL of combustibles simultaneously. They typically come with multiple sensors, one for each target gas. They are often used in new or unfamiliar environments with more than one hazardous gas. These devices require more upkeep and maintenance than single-gas detectors. You will need to replace each of the sensors after a set period of time to ensure the device will produce accurate results.
What is the bump test?
A gas monitor bump test is a way of making sure the gas monitor is working properly by checking that the alarm on the detector will go off if there are hazardous gases present in the air. The user will attach a cylinder of the target gas to the detector. If the device is working properly, the alarm will go off. This shows the user that the device is safe to use. However, bump tests do not test the accuracy of the device. The worker may need to recalibrate the device to ensure that the device will produce accurate readings in the field if a bump test fails. We recommend calibrating our gas monitors at least every 6 months.
Use RKI controllers to make the most of your fixed gas detection equipment. If your devices need calibration or a diagnosis for a potential repair, PK Safety can help with our gas detector calibration and repair services. Our staff is trained by RKI and we are a Factory Authorized Service Center for RKI Instruments.
