Previous proof of firecrackers injuries here.
For those who don’t believe in injuries caused by firecrackers explotion. I just saw a patient in the E.R. of my hospital who came because he was walking near a park and some kids were buying firecrakers in the street. A kid ignited a firecracker and it exploted next to the box that containded the firecrackers. The patient was 10 ft away from the box and the explotion cause this right side injuries.
As you can see, the injuries are projectile-like injuries and he didn’t burn. A witness told me that lots of wood sticks and asphalt stones flew far away.
A Plastic Surgeon and I repaired the injuries and noted an irregular perforation at the right cheek, that penetrated towards the floor of the orbit and produced a coronoid apophysis fracture.
I strongly recommend never play with firecrackers.
