A teacher and at least four Grade 11 students suffered minor injuries in a chemical explosion in a science lab at Brennan Catholic High School in Windsor, Ont., on Tuesday morning.
The school was in a medical lockdown for about about an hour and a half as Raymo Road was blocked off, and ambulances, fire trucks and a hazardous materials response team were called to the scene.
According to Windsor police, at around 10 a.m. ET, an experiment in a test tube went wrong, causing shards of glass to injure a chemistry teacher.
Chemistry teacher Steve Pellarin received lacerations on his face and arms, and was taken to hospital in an ambulance. The 17 students in the class were taken to hospital in a schoolbus for observation.
Eight students were examined at the scene because the explosion left them with ringing in their ears. None of the students received chemical burns.
The experiment included the use of the ingredients potassium chlorate, manganese dioxide, sugar and glycerin.
The principal says there will be an investigation.

This is the sort of thing that at the very least should be behind protective shielding and handled remotely - but preferably should be in a metal container which would not have shattered.
Sounds explosive to me, from what I remember from my chemistry classes.
Is anybody but me old enough to remember the time when this would have only been a funny story at the family dinner table, instead of a ‘headline’??
Or when the only ‘First Responder’ involved would have been the School Nurse??
We’ve come a long way, bay-bee.....
...and imbues one bookish, nerdy kid with superhero powers.
Oh yeah? Where else would you try that one?
The chemistry teacher did not have a CO2 permit. He should have his teaching license revoked, be subject to a climate tax for the remainder of his life, and perform climate change service.
Student: “So teach, does this mean the we don’t get a passing grade?”
For what? Carbon dioxide inhalation?? Come on, Canada, snap out of it.
Now class, can anyone summarize for us what we have learned today?
Indeed ... making explosives in a test tube ... what could possibly go wrong?
One of these days I'll tell you of the day I blew the heel off of one of my mother's shoes, and how she damned near beat me to death!
Don't put the test tube containing PETN over the Bunsen burner?
Even when they do, crap happens. One of my science teachers (apparently a few years before I entered high school) did a series of experiments one day, dumping the results down the sink as he went. Some time later, all those experiments got to know each other in the pipes under the corridor outside the guidance office. Boom.
(By the time I got to high school, he was just gassing us with 30 cents worth of pennies dropped into a jug of nitric acid.)
Very good, 17th Miss. You’re excused from the next test!
Oh, please tell me you weren’t wearing them at the time! :)
In an al-qaida high school, an explosion that injured 5 would only get you a C. You have to KILL at least a dozen for the A.
No, but she was.
***The experiment included the use of the ingredients potassium chlorate, manganese dioxide, sugar and glycerin.***
The old Fur-Fish Game (Harding’s Magazine) books said that two of these were good for making homemade smokeless shotgun propellant.
I’ll just stick with Green Dot!
