The Triangle Shirtwaist Fire

Explanation:

The Triangle Shirtwaist Fire was the deadliest industrial disaster in US history. It occurred on March, 25th, 1911. The biggest problem was that owners locked fire escape doors, and many people were trapped in the building, trying to jump from it, but dying in the process. The building was very tall, and the ladders were not long enough to reach the top floor. People on the highest floors could not be saved by the firefighters. There were nearly 150 dead.

What was the key to the changes that were the aftermath of the fire is that workers tried to improve conditions beforehand. Even the question of the locked fire exits was raised.

After the fire and the scandals that broke out, the protection laws were made – thirty-eight of them for the labor in New York state. Fire-prevention legislation was introduced, followed by inspection of the workplace and safety and formation of the American Society of Safety Professionals.
