SFPD Capt. Mariano Elias told the California Post that the toxic mixture was linked to a hot tub at the club.
“They mixed 30 gallons of muriatic acid with chlorine and it became a toxic vapor,” he said.
A visitor to the club inhaled the vapors and took himself to the hospital for treatment, club manager Randy Lim told The Post, describing the man as in his 20s.

“Our HazMat units and fire companies are working to assess the situation, identify any potential hazards, and ensure the safety of the public and our first responders,” the SFPD said.
Elias added that the department of Public Health responded and that crews were able to dispose of the mixture in four and a half hours.
“The mixture has been cleared,” Elias said.
