SANTA CLARITA, Calif. (AP) – A roller coaster that struck and killed a ride operator at Six Flags Magic Mountain will reopen Monday, the amusement park said Saturday.

Investigators from the Occupational Safety and Health Administration tested the SCREAM! coaster’s braking system after the death Friday morning and the ride was cleared to reopen, said Sue Carpenter, a park spokeswoman.

The ride was closed after the death of Bantita Rackchamroon, 21.

Rackchamroon, who had worked at Magic Mountain since March, walked onto the coaster’s tracks in a restricted area before the park opened Friday morning, Carpenter said.

Carpenter said Rackchamroon was performing a routine safety inspection when she was struck during a test run.

Dean Fryer, a spokesman for the California division of OSHA, said Friday it appeared that “the employee walked across the tracks (when exiting) instead of through an exit gate.”

There was no answer Saturday at Cal-OSHA offices.
