San Bernardino County sheriff's spokeswoman Cindy Bachman told the media that explosives experts removed the harmless device from the man, who is said to be in his 50s. An X-ray test found that it was not an explosive.
According to the Los Angeles Times, the incident led to the shutdown of traffic inside and outside the emergency room. The front entrance of the hospital, however, remained open.
The Associated Press reported that the man was put on a stretcher and rolled out to the parking lot where a bomb squad removed the device. Workers got the all clear afterwards.
