In today's world, teachers can no longer enter the classroom and just focus on reading, writing and arithmetic.
They have to also be prepared to act as first responders in a shooting or mass casualty incident.
According to Emily Rowles Saraceni, a Mercy Hospital EMS liaison, the number one cause of death is uncontrolled bleeding in trauma patients.
Since Columbine, there have been several deadly school shootings. That's why Attica Central School teachers took part in special training Friday, sponsored by Mercy Hospital called "stop the bleed."
"We don't know what is going to happen day-to-day. So we have to be prepared for anything," said Sherry Bennett, an assistant principal at Attica Middle School.
EMS professionals taught the teachers how to properly insert special clot-making gauze and their fingers into a gun shot wound to a save a life.
The proper use of advanced tourniquets was also covered. But the drug epidemic is also taking many young lives.
Teachers were required to search a simulated teenagers bedroom to find 54 hidden drug items.
It was an eye-opening experience created by the Genesee Council on alcohol and substance abuse, as many drugs were found in watches, picture frames, false water bottles, deodorant, and even highlighters.
The school district is also looking to update teacher go-bags to make sure they have supplies for shootings and mass-casualties as the evolution of school safety continues.
