Why was the death toll in the Triangle Shirtwaist Factory fire so high?

The death toll in the Triangle Shirtwaist fire was so high because the conditions of the factory was poor from a fire safety standpoint. The fire safety precautions were minimal, and as was standard for the time, there were no fire drills. The doors were kept locked during working hours and communications between floors was ineffective at the time of the fire. Also, the city fire department did not have equipment able to reach to the fire floors from outside.
