Officials: Fatal explosion was accident Authorities say a June explosion that killed one person at Waconia Farm Supply was an accident.
The Carver County Sheriff's Office, the Waconia Fire Department and the state fire marshal's office announced findings of their investigation Wednesday.
They concluded that a 100-pound propane cylinder exploded, killing 18-year-old Ryan Samuelson, of Cologne, Minn.
Deputy State Fire Marshal Bruce McLaughlin says testing on pieces of the cylinder showed it previously contained acetylene -- a highly flammable gas that's safely stored only in acetylene cylinders after being dissolved into a solvent to keep the gas stable.
In any other container without safety features, acetylene could generate enough heat to cause a violent explosion.
The state Occupational Safety and Health Administration says no citations will be issued.
