Any work environment where elevated levels of potentially harmful gases may exist must have a detection system in place. Many harmful gases are odorless, and the threat to worker health can go unnoticed until it is too late. Chemical plants, petroleum refineries, waste product treatment centers, and any other industrial setting that uses or produces toxic gases can be fitted with a special detection system that is linked to both an alarm controller and a central readout/operations monitor.
Substances such as carbon dioxide, hydrogen, hydrogen sulfide, and other volatile organics are often produced when chemicals are undergoing changes due to the introduction of reagents. Similarly, these toxic gases are often used in the chemical production operations when solvents, combustible liquids, or reagents are being manufactured. At strategic points throughout the facility, sensors are placed that can detect the levels of these gases in the indoor or outdoor atmosphere. These sensors are connected directly to an alarm control panel. Planning and installing this type of detection system is performed by experienced gas detection personnel who market and distribute all of the equipment required.
Planning The Detection And Alarm System
Each work environment is unique in its layout. The size of the facility, the gases that are used or produced, and the network of chemical transportation pipes are studied in detail. The actual placement of the sensor array depends on all of these factors. For example, if a chemical production company uses gas piping and mixing containers, sensors can be placed directly on each critical point throughout the pathway. Gaskets, hoses, and even confined areas near boilers, chemical extruders, and mixing containers can be fitted with local sensors that connect directly or wirelessly to the alarm controller.
When study of the facility layout is completed, the proper sensor type is chosen. The models used can be specifically calibrated to detect the ppm of a certain type of gas. These sensors are carefully calibrated to ensure reliability.
Installing The Alarm Controller Unit
The alarm control mechanism is a box that contains software written to accept electronic coding information from each of the sensors. This unit is generally placed in a centralized location. Advanced models have a very large detection radius and can receive wireless signals from sensors located as far as 100 meters away.
Most of these control panels have both an audio alarm and alarm light. They are specially programmed to receive and decode input from sensors in much the same way an automobile control computer receives data from engine and transmission sensors.
Once the alarm control panel is in place, it can be wirelessly connected to a central readout station. The system can be programmed to automatically shut down machinery or contact emergency response centers.
Contracting With A Gas Detection Company
GDS Corp is an industry-leading gas detection company that markets complete gas and flame sensor networks and alarm control boxes for all industrial/commercial environments. Partnering with an experienced gas monitoring specialist means peace of mind for the client because maintenance, device re-calibration, and even worker safety training is included in the contract.
