Safety audits for LPG bottling plants combine process safety, fire protection, electrical hazardous area compliance, and PESO licensing requirements into one of the most comprehensive and consequence-critical audit types in Indian industrial safety. LPG (liquefied petroleum gas) has a lower explosive limit of 2.1% in air — meaning even a small release in an unventilated area can form an explosive vapour cloud ignitable by any electrical spark, heat source, or static discharge. According to PESO licensing data, India has over 6,000 LPG bottling, storage, and distribution facilities subject to Petroleum Rules 2002 and Explosives Rules 2008 jurisdiction, with fire and explosion incidents causing disproportionate Rs50 crore-Rs500 crore consequences per major event.
Karnataka’s coastal industrial belt around Bantwal (Dakshina Kannada district) hosts several petroleum product distribution facilities servicing the Mangaluru-Bengaluru corridor. An LPG bottling plant in this area typically operates under: PESO licence under Petroleum Rules 2002, factory licence under Karnataka Factories Rules 1969, fire NOC from Karnataka Fire and Emergency Services, and environmental consent from the Karnataka State Pollution Control Board. A comprehensive safety audit covering all four regulatory frameworks costs Rs4-12 lakh for a medium-sized plant, but addresses consequences in the Rs50-500 crore range if a fire or explosion occurs.
