Reports have subsequently highlighted that only one of the workers at the plant remains in hospital, suffering from chemical burns, while highlighting a history of incidents at the plant in the past, though recently no incidents had been reported. 

The fire was soon contained.

SunEdison relies on the Pasadena plant for granular polysilicon production that it converted into solar wafers for supplying to its sub-contracted solar cell and module suppliers. The PV modules are then used in its downstream PV power plant business.

The company had previously spun-off its semiconductor polysilicon and wafer operations into SunEdison Semiconductor.

SunEdison has also noted to PV Tech that OSHA had released the Pasadena facility to resume operations on Sunday.

However, the company said that it was going through normal safety inspection and start-up processes with the expectation that full plant operations would resume the week of October 5.
