8 Station Safety Equipment Overview <br /> Each LNG fueling station is designed with high standards for safety and reliability. This LNG fueling station meets and <br /> exceeds all ASME and NFPA code requirements. Its emergency shutdown system has been integrated with methane <br /> detectors, fire detectors, Emergency Shutdown Device (ESD) buttons, an alarm horn, alarm beacon, and auto dialer. <br /> This same system operates on circuits equipped with battery backup power supplies; in the event of a loss of power, <br /> all equipment integrated with the emergency shutdown system will remain operational. Control air is sent to the <br /> automatic valves via plastic airlines—in the event of a fire,these plastic lines will melt, causing the valves to close. <br /> 8.1 Fire Alarm Control Panel (FACP) <br /> The Fire Alarm Control Panel (FACP) is a UL listed auto-dialer that receives signals from our fire safety devices and <br /> transmits those signals to a 3rd party monitoring system for reporting and dispatching of the proper responders. The <br /> FACP is programmed to call a 24/7 fire monitoring service whenever a particular alarm zone is triggered. This <br /> monitoring service will then communicate directly with the Clean Energy Command Center. <br /> In regards to the alarm zones, there are a total of seven programmed to communicate through the FACP: <br /> ❑ Zone 3—Process Control Alarm <br /> ❑ Zone 4—Emergency Shutdown Device (ESD) <br /> ❑ Zone 5—Methane Device Fault <br /> ❑ Zone 6—Methane Detection Alarm <br /> ❑ Zone 7—Flame Detector Fault <br /> ❑ Zone 8—Flame Detection <br /> o Activation of Zone 8 will notify the Fire Department through the fire alarm monitoring service. <br /> 8.2 Emergency Shutdown Device(ESD) <br /> Emergency Shutdown Devices allow for manual activation of a fueling station's emergency shutdown function. This <br /> LNG fueling station is equipped with red "mushroom-type" buttons, which can be pushed to active the emergency <br /> shutdown function. Once activated, the motor control center shuts off power to all solenoid valves and equipment, <br /> halting fuel dispensers for the whole station and isolating any gas in the system. ESDs have been strategically located <br /> specifically for each site in accordance with all prevailing code. <br /> ■ Activating an ESD <br /> The following safety measures take place automatically after an ESD activation: <br /> ❑ The station and pumps shut down <br /> ❑ All air-operated valves close <br /> ❑ The red alarm beacon illuminates <br /> ❑ The alarm horn activates <br /> ❑ Electrical power to all electrical equipment disconnects <br /> ❑ The methane-detected circuit on the fire alarm control panel activates <br /> ❑ The auto-dialer initiates communication to the preprogrammed phone number schedule <br /> ❑ The alarm is logged into the alarm system of the PLC <br /> ■ Clearing the Alarm <br /> ❑ The alarm reset button on the front of the control panel must be pressed <br /> ❑ The alarm must be acknowledged on the PLC interface screen on front of the control cabinet <br /> L/CNG Emergency Response Plan �, Clean Enerav- 4 <br />
