Liquefied Petroleum Gas

The Department of Oregon State Fire Marshal regulates the Liquefied Petroleum Gas (LPG) industry in the state of Oregon through the Regulatory Services Division (RSD).  The LPG unit in this division employs Compliance Specialists and support office staff members to help accomplish this.  

The Compliance Specialists regularly perform inspections on LPG tank installations throughout the state of Oregon.  These inspections are done at random each month in select counties.  Completed inspections ensure that LPG tank installations are being done safely and in accordance with the Oregon Fire Code. 

The Regulatory Services Division also has support staff that process licensing, exam applications and documentation for companies and installations.
