Emergency

A man was killed Thursday morning when the oil rig on which he was working exploded north of Baker. 

Chad Tronstad, 39, of Baker, died when the rig experienced a "pressurized explosion," said Fallon County Sheriff Trenton Harbaugh. 

The explosion happened at 11:45 a.m. on Thursday at an oil rig north of town. Harbaugh said officials are actively investigating the incident. 

Harbaugh couldn't remember the last time the county dealt with an oil rig explosion. 

"It's been a while," he said.
