Propane tanker crashes and leaks in Wisconsin; Vermont house explosion after a leak kills two

Andy Will, Chief Editor · Wednesday, September 09, 2026

Two propane accidents inside a day put the handling end of this business back in the headlines. A tanker crashed and started leaking in the Town of Frankfort in Marathon County, Wisconsin. Emergency crews asked people to stay out of the area. In Vermont, a house explosion after a propane leak killed a mother and her son during a birthday party. Nothing here moves the wholesale price. Both go straight to the part of the job that carries the real liability.

The Frankfort crash

A propane tanker crashed in the Town of Frankfort and led to a leak, and Marathon County crews responded and told the surrounding community to avoid the area. Little else is confirmed so far. No injury count, no cause, no word yet on how much product was on the truck or how much got out.

For a hauler, the crash matters more than the cleanup. A loaded bobtail or transport on a rural Wisconsin road is the exposure every propane marketer already knows about, and this is the season when the trucks start running hard again. Watch for the DOT and state findings on cause, because that is what drives the next round of driver and equipment scrutiny.

The Vermont explosion

A propane leak at a house in Vermont ended in an explosion that killed a mother and her son at a birthday party. The report ties the blast to a leak. It does not say whether the source was a tank, a line, an appliance, or a service error.

When a fatal home propane explosion happens, the liability fight follows, and where the leak started decides who is on the hook. A dealer who set the tank and ran the last leak check has a different day than one who did not. The cause report is the thing to wait for.

Suburban Propane cut to Hold

Zacks Research downgraded Suburban Propane Partners, ticker SPH on the NYSE, to a Hold rating. No price target or reasoning came through in the wire copy, so treat it as a sentiment read on one of the larger retail propane names rather than a signal on propane demand itself.

What to watch

Three things over the next few days. The DOT and Marathon County cause finding on the Frankfort tanker, which sets the tone on hauler scrutiny heading into heating season. The Vermont fire marshal's determination of where that leak started, since it decides liability. And whether more analysts follow Zacks on SPH or the Hold sits alone.
