what changes occurred in the aftermath of the tragedy within what time period did the changes happen? (tragedy as in triangle factory fire)

In Manhattan, New York City, on 25 March 1911, the disastrous Triangle Shirtwaist Factory fire took place.

It was confirmed that 146 individuals died of asphyxiation, smoke inhalation, fire burns, collapsing buildings that caved under pressure and damaged buildings, and there were others who leapt to their deaths.

In the wake of the horrific incident,

The American Society of Safety Workers was commissioned in New York City on October 14th 1911 with the objective of investigating situations within and beyond New York City to discover situations that can be prevented using the power of the legislature.

Cheers.

uncanny would be like unlucky or disaster. you can look for more in the dictionary or if you have text book then turn to a. 17 but it's different with textbooks.
