Response Considerations Gas Release Natural Gas is lighter than air Mercaptan may separate from venting gas and is heavier than air Venting cylinders can be recognized by high pitched gas release noise Rapid Decompression can create extremely cold temperatures & static electricity Use of water to control vapors may freeze vent ports or increase rate of decompression Control potential ignition sources Portable Pipelines.com Slide 40 Response Considerations Isolation and Evacuation based on ERG Guide 115 Leak with No Fire Isolate 330 feet in all directions Leak with Fire Isolate 330 feet in all directions Evacuate ½ mile downwind Evacuate 1 mile downwind Portable Pipelines.com Slide 41 Response Consideration Up-righting Module Controlled Venting Flaring Portable Pipelines.com Slide 42 Chris Christopoulos, Jr. 14
