Effective Standard Operating Procedures (SOPs) are non-negotiable in the energy sector, particularly when managing high-hazard materials like Liquefied Natural Gas (LNG) and Liquefied Petroleum Gas (LPG). These detailed guidelines are foundational for ensuring safety and managing emergency response during leaks and fires.Our procedures emphasize strict general precautions, requiring responders to approach the incident from upwind and immediately evacuate all personnel from the path of the vapor cloud. A key focus for LPG handling is the severe possibility of a BLEVE (Boiling Liquid Expanding Vapor Explosion) if fire impinges on an unprotected tank shell above the liquid level, necessitating careful fire control strategies.The SOPs outline specific control methods tailored to the unique properties of these cryogenic vapors and liquids. This includes mandating that personnel wear proper protective clothing and self-contained breathing apparatus, utilizing specialized materials like Hi-ex foam for LNG spill coverage or fire radiation control, and employing water spray monitor nozzles for effective vapor cloud dispersion while strictly avoiding applying water directly to large pools of LNG or LPG, which intensifies vaporization. Following these protocols precisely helps limit damage and protect life by ensuring controlled responses to dynamic, hazardous situations.
