A pool service worker breathed in hazardous vapors at a San Francisco golf course. He took himself to a hospital. Fire crews with a hazmat unit were called to the scene.
One person was admitted for treatment. Officials did not immediately say what chemical was involved. They also did not say how the worker was responding. The type of chemical and the worker's condition were still unknown. Emergency crews were called out after the report was received. The worker had gone to the hospital on his own. No further information could be obtained at that time.
