What was the primary reason for the high death toll in the Triangle Shirtwaist Factory fire?

The fire killed many workers because the factory had inadequate fire-safety protections, including locked or inaccessible exits and no sprinkler system. At the time, there were few legal requirements for fire exits, sprinklers, or safety inspections, which allowed dangerous conditions to persist. Therefore, the best answer is “There were no legal requirements for fire exits, sprinkler systems, or safety inspections.”
