What is the historical significance of the Triangle Shirtwaist Factory Fire? (Please make sure to mention reform, worker's rights, working conditions, and working hours, all that good stuff)
I will mark Brainliest

The fire led to legislation requiring improved factory safety standards and helped spur the growth of the International Ladies' Garment Workers' Union (ILGWU), which fought for better working conditions for sweatshop workers.

Explanation:

I'm pretty sure it started a bunch of reforms and laws that bettered working conditions, set work week hours to like 45hrs. You be much better off looking this up though.

Explanation:

The fire was caused by a cigarette when it came into contact with the floor because it was so dirty. (at least that's what I remember)

necessary and proper clause. the congress shall have power to all laws which shall be necessary and proper for carrying into execution the foregoing powers, and all other powers vested by this constitution in the government of the united states, or in any department or officer thereof.
