In remembrance of the Triangle Shirtwaist Factory fire in New York City that led to the deaths of 146 garment workers in 1911, the American Society of Safety Professionals (ASSP) has released a podcast that covers the far-reaching impact of the disaster.

ASSP also encourages all companies and their workers to join the Society to observe a moment of silence at 4:45 p.m. ET on Saturday, March 25—the exact time the first alarm was sounded—to pay tribute to the workers who died in the fire, while also refocusing on creating safe work environments. ASSP reports that it contributed to a memorial at the original site.

“The Triangle Shirtwaist Factory fire inspired our country to address workplace safety in an organized way that didn’t previously exist,” said ASSP president Christine Sullivan. “The tragedy led to a series of laws and regulations that better protected workers. It also caused a concerned group of insurance company safety engineers to start an organization that is now ASSP.”
