Gas Systems

​​​​Plan reviews are done by the Division of Industry Services (DIS) for gas systems - anhydrous ammonia, compressed natural gas, liquid natural gas, liquid petroleum gas, and liquid and gaseous hydrogen. Periodic inspections are done on the anhydrous ammonia and hydrogen systems. Inspections of the other systems are completed after initial installation or upon owner's request.

Questions regarding gas systems code can be sent to DSPSSBBoilertech@wisconsin.gov.
