PITTSBORO, N.C. (WTVD) -- Two workers were injured after an explosion inside a food truck on Thursday at an event in Chatham County.
The Chatham County Fire Marshal is investigating the blast, which happened about 12:30 p.m. at the Shakori Hills GrassRoots Festival.
Fire Marshal Billy Judson said a propane gas leak caused the blast inside the Stuffyman's Vegan Stuff food truck.

The ensuing fire was isolated to the food truck, and two workers inside were hurt. They were taken to the North Carolina Jaycee Burn Center in Chapel Hill, and their conditions are unknown.
One of the people injured was the owner of the food truck, Eric Zeigler. His wife told ABC11 that her husband was burned on 30% of his body.

She said he's expected to receive treatment at the burn center for a few months.
There was no update on the other person hurt.
Judson credited the Shakori Hills staff for acting quickly to grab fire extinguishers before emergency personnel arrived.
The North Chatham Fire Department, Silk Hope Fire Department, Chatham County Sheriff's Office, Pittsboro Fire Department, and FirstHealth EMS responded to the incident.
The festival is continuing as planned.
"Today at the 21st Annual Fall Shakori Hills GrassRoots Festival of Music & Dance, during setup and before music and main activities began, there appears to have been a propane explosion within a food truck. Two people were injured, and thanks to the quick response time of the festival's Health & Safety Team alongside Chatham County's Fire, EMS and Sheriff's departments, they were quickly taken to the hospital," a spokesperson for the festival told ABC11. "The incident is currently under investigation, and the beloved annual festival will proceed this weekend as planned."
