A high-level detected emission that may represent a potential safety concern is communicated immediately through an alert and/or alarm. These alerts require immediate attention and can serve as an augmentation of existing facility safety systems. Other, more routine emissions are detected and communicated over time (hours to days), with repeating detected concentration peaks under varying wind directions building confidence in the assignment of an emission event.
Once a notification threshold is reached, a Potential Source Location (PSL) window is assigned. The LDAR personnel respond, per the DRF, to investigate the PSL and identify the source of the emission. The identified source is then measured with calibrated Method 21 equipment (or Optical Gas Imaging) to document the leak’s peak concentration value and initiate repair procedures. All information regarding the leak is efficiently entered into a mobile device and recorded for regulatory, operational, and quality assurance purposes. Other information, such as maintenance activities, are entered into the system to facilitate the operation of the LDSN.
