Overview
- San Francisco Fire Department crews responded to the Presidio Golf & Concordia Club after an accidental mixture of muriatic acid and chlorine produced hazardous fumes and one person was taken to hospital for inhalation.
- Fire officials posted photos of the response on social media and urged residents and businesses near the course to follow emergency instructions and avoid the scene.
- Muriatic acid mixed with chlorine-based compounds can release toxic chlorine gas and other airborne hazards, which explains the department’s hazmat response and the inhalation injury.
- The golf course borders the Presidio Terrace residential area along Arguello Boulevard, raising exposure concerns for nearby homes and businesses during the incident.
- Key details remain unresolved because officials have not confirmed the hospitalized person’s identity or condition and have not given an estimate for when cleanup will be complete, and aerial footage later showed crews had already left the scene.
