    Three people suffered serious injuries in roofing accident on Clayton Street in San Francisco. Jan. 24, 2014.

    Cal/OSHA has been called in to investigate a serious construction accident near San Francisco’s Twin Peaks.

    Three workers were seriously injured.

    The men, aged 24, 50 and 58, were working on a home at 1412 Clayton Street around 9:30 a.m. when a scaffolding collapsed, causing them to fall 25 feet, fire spokeswoman Mindy Talmadge said.

    All three workers were taken to San Francisco General Hospital. Two are said to have potentially life-threatening injuries. The third is listed in serious condition.

    Talmadge said the workers were employed by the owner of the single-family home who was having work done and was not present at the time of the fall.

    A building inspector told NBC Bay Area they didn't have appropriate permits.
