I-CAR · May 29, 2019
Summary
This article provides an overview of Liquid Petroleum Gas (LPG) powertrains, highlighting their similarities to traditional gasoline engines and their unique high-pressure fuel storage and delivery systems. It emphasizes the safety precautions required during collision repairs, particularly regarding the sensitive electrical systems and temperature-sensitive high-pressure gas tanks.
What to do on the job
Disconnect and isolate the 12-volt battery before welding to protect sensitive electrical components, and ensure LPG storage tanks are only painted light or reflective colors to prevent heat absorption and accidental gas venting.
How to use it
Use this document to justify the labor and safety precautions required when working on LPG/propane vehicles, specifically the necessity of disconnecting the battery before welding and the strict refinishing requirement to only use light or reflective paint colors on the fuel storage tanks to prevent dangerous pressure build-up.
