The workers were standing on scaffolding about 16 feet off the ground at an apartment building on 10th Avenue and Park Boulevard, next to Petco Park, when the platform collapsed, San Diego Fire-Rescue Department (SDFD) Batt. Chief Glen Holder said. It was not clear what caused the scaffolding to collapse.
All were transported to UC San Diego Medical Center with traumatic injuries, SDFD spokesperson Monica Munoz said.
California Occupational Safety and Health Administration (Cal/OSHA) was looking into the incident.
No other information was available.
