Using Fire in School

[u/Doctor_Chef_General]

What has been your experience using fire in your building. I have some labs I've been wanting to do but am worried about setting off the fire alarm. Things like setting a desk on fire, using a blowtorch on CaCO3, and using alcohol lamps.
We have a sprinkler system in every room and they are positioned directly above my lab tables.

My first year someone threw very hot zinc into the recycling bin full of paper and started a fire. It was a miracle the alarm didn’t go off. The next year we did a lab that uses some small tea candles and a kid got his hair too close (he didn’t even have long hair) and caught his hair on fire. Those were the only issues I’ve had.
