San Francisco General gets record fine after fatal workplace stabbing

Frontline staff at Zuckerberg San Francisco General Hospital are now facing the strongest workplace-safety penalty in the case of Alberto Rangel, the 51-year-old social worker killed at Ward 86, the hospital’s HIV clinic. Cal/OSHA cited the city-run hospital for seven workplace-violence-prevention violations, six of them serious, saying the hospital failed to take adequate steps to protect workers even after violence risks were known.

The $130,500 penalty lands as an accountability test for a public hospital where nurses, social workers and other staff have long worked in high-stress settings with patients in crisis. Ward 86 sits at the center of that pressure, and the fatal attack there on Dec. 4, 2025, forced renewed scrutiny of whether the hospital had a meaningful prevention plan, training and response procedures in place before Rangel was stabbed multiple times. Cal/OSHA’s findings came nearly six months after the killing.

Rangel was arrested at the hospital and charged with murder. Prosecutors said he came in with a concealed knife, spoke to a social worker and then attacked Rangel in or near an elevator. UCSF said Rangel had spent more than 15 years in the San Francisco public health system, including the last five years at Ward 86, where memorial statements identified him as Alberto Rangel, LMFT, and described him as a spouse, brother and friend.

The state enforcement action extended beyond the hospital itself. Cal/OSHA separately fined UCSF $142,700 for multiple citations and for not having an adequate violence-prevention plan, underscoring that regulators saw the problem as part of the broader system that operates the clinic. The findings also matched concerns raised by staff before the stabbing, when workers reported the patient’s behavior and threats.

After the killing, health care workers, community members and hospital employees held vigils and protests demanding safety changes, while San Francisco Supervisor Shamann Walton called the death a devastating tragedy and pressed for better security. The case has since become about more than one attack: it has put the city’s public hospital system on notice that violence prevention in emergency, psychiatric and social-work settings cannot be treated as paperwork alone.
