Detecting Combustible and Toxic Gases in HVAC Ducts
Air handling systems are used throughout industry to provide comfort and health in manned areas. From systems that deliver fresh air in confined spaces, to HVAC systems in living quarters, exhaust / ventilation systems form part of the essential safety services of chemical process and petroleum facilities. Nevertheless, if unprotected, facility ventilation systems can transport combustible and toxic gases from a source area to other parts of the building, bringing the dangerous substances into non-hazardous areas, like control rooms, living quarters, electrical switch rooms, and equipment rooms.
Detecting Combustible Gas Leaks in Compressor Stations
In gas compressor stations, there is a high risk of fire and explosion due to a combination of intense heat, pressure and vibration. General Monitors offers several highly reliable gas detection solutions that help maintain safety in gas compressor stations. Ultrasonic, Infrared and Catalytic Bead gas detectors can be used alone or in integrated systems to help stabilize hazardous environments.

How to Select a Flame Detector
Process and plant engineers in the oil and gas industry and a wide range of other hazardous process and manufacturing industries require continuous flame monitoring equipment to prevent catastrophic fires. In order to select such detection equipment, users should understand the principles of flame detection and review the types of detectors available today. Armed with this knowledge they will be better able to match the appropriate flame detector to process and site performance requirements and to the type of hazard whose consequences the instrument is designed to mitigate.

New Point IR Calibration Tools Now Available
We are pleased to announce that a new Remote Gas Calibrator is available for the IR400 Infrared Gas Detector. Since some gases are lighter than air, it is common to install IR gas detectors in ceilings, ducts, and other spaces where gas accumulation occurs. Performing routine maintenance on these devices is often difficult, requiring scaffolding, ladders, or lifts to bring technicians to the detectors. The RGC-IR now makes it a lot easier to calibrate remote mounted infrared gas detectors. It permits users to test and calibrate the IR400 and its predecessor, the IR2100, from as far away as 100 feet (31 meters)! The RGC-IR does not affect sensor response, as evidenced by T50 response times of 6 - 7 seconds and T90 response times of 10 seconds and is suitable for operation at maximum air velocities of 13 meters/second (30 miles/hour).

Flame Detectors with HART® Communications
The FL3100H UV/IR and FL3101H UV Flame Detectors are now compatible with the HART® communication protocol. Enabling the FL3100H UV/IR and FL3101H UV Flame Detectors with HART enhances the productivity and available data of these instruments, thereby improving safety. Standard HART commands make it simple for systems to configure and adjust the flame detectors to the particular requirements of the plant. The flame detector, for example, can be tagged with a name for greater ease of use (ex. “Reactor 1 flame detector”). Alarm and warning set points can be adjusted, delay times set, and alarms acknowledged or reset by simply sending a command. Such real-time, continuous access to device variables improves control.

A Straightforward Approach To SIL Certification
As we have discussed in previous articles and papers, the concept of functional safety is a confusing one. Unfortunately, the IEC 61508 and IEC 61511 standards are not easy to read and are open to interpretation. This results in a plethora of third-party companies and so-called experts making their own judgment on the appropriate implementation of these standards. While one could argue both for and against the approach of using a third-party to issue a certification to these standards, the fundamental problem is that there is room for debate.

Remote Gas Calibration Now Made Easier
Calibrating General Monitors S4000CH Combustible Gas Detectors is now easier than ever with the new Automatic Remote Gas Calibrator (ARGC). Because several gases that are the byproduct of petroleum production are lighter than air, it is common to install combustible gas monitors in ceilings, turbines, ducts, and other spaces where gas accumulation occurs.

New Advanced IR400 Detector For Single- or Multi-Point Combustible Gas Monitoring
Hydrocarbon gas leaks are a life-threatening hazard that can also damage equipment and plant infrastructure. Combustible gas leak monitoring is therefore essential for industrial operations where hydrocarbon releases can occur.

Impact of gas detection coverage on SIF SIL Rating
Selecting the technology and knowing where to place gas detectors for maximum coverage effectiveness are probably the two most critical decisions for any fire and gas system (FGS) designer. A wrong choice of technology coupled with an inappropriate positioning of the gas detector may render the gas detection loop completely ‘blind’ to nearby gas leaks.
