A ruptured pipe caused an explosion in Santa Maria, CA, last Saturday, officials said.
Fire crews were sent to a HazMat call to Windset Farms, located at 1650 S. Black Road, just before 5 a.m.
A release of CO2 liquid ruptured a pipe buried in the ground and was heard and felt by people at the site, said officials at the Santa Maria Fire Department.
The leak happened near a greenhouse, away from storage tanks.
A plant worker was able to shut off the CO2 flow quickly, and the vapor dissipated into the air, fire crews said. After the shut off, fire officials canceled the HazMat response.
One person was taken to the hospital as a precaution, but the condition was unknown.
The cause of the rupture is also unknown.
