What is the requirement for gas detection?
A gas detection system is a critical piece of equipment for any workplace. Whether in a factory, warehouse, or lab, it can protect workers from suffocation, injury, death, and property damage caused by leaking gasses.
The gas detectors must be installed correctly and comply with the requirements of the standard in which they are certified. The gas detectors must be mounted securely, independent of vibration, and protected from equipment traffic. They should be placed to maximize coverage, and the sensors should be 12-18 in. above grade (Figure 1).
Installation of Fixed Detectors and Personal Detectors
Personal gas detectors are often used to monitor an operator’s breathing zone continuously. These devices in Gas detection Australia are usually small and can be worn on the operator’s wrist or hand, allowing them to move around the work area safely.
NFPA 820 requires that gas monitoring systems be installed in areas where flammable, oxidizing, or highly toxic gases are present. They must be capable of detecting these gases when the concentration is above 25 percent of the lower explosive limit.
Calibration of Direct-Reading Portable Gas Monitors
Instrument calibration refers to the process of comparing the instrument’s response to a known traceable concentration of test gas. When performed properly, it ensures that the DRPGM will respond accurately to the gases it is designed to detect, thereby warning users of hazardous conditions before they reach dangerous levels.
