I believe that the main reason it was so dangerous was the limitations on health and safety regulations enforcing employers to properly care for their staff.
Children were allowed to be over worked and underpaid.
Work conditions were dangerous, often with poor ventilation and disregard for proper safety measures when operating or working on machinery.
Oftentimes, any safety regulations that might have been followed were often ignored when it came to immigrants.

Tariffs obviously increased the price of imported goods but also discouraged European countries from trading with America due to these taxes. This issue split Northern and Southern politicians for decades leading up the Civil War.
