rule number one of working with explosive reactions.
BLOW THAT FUCKER UP
and do it quite a few times in as many interesting and different ways that you can.
then try not to blow it up.
you will find you will have a better chance of not blowing something up if you have already
seen the puppy in action before.
you will also have a much better idea of when you realy are in danger.
pyrophorics 
make them catch fire.
try and see how little O2 is needed for them to burn by leaking gas into your argon
environment.
still all very basic stuff.
its the thermodynamics of some reactions and the toxicity of some compounds that really
scare me.
I really have to find an acetone peroxide oxidation that works on a cannabinoid now just
for shits and giggles
(Acetone peroxide is a big no no. don’t make it don’t touch it don’t hang with dudes who make or touch it trust me going blind is the least of your worries with this one)
oh and germs I hate germs.
this guys blog has a section on things he will not work with.
ive worked with a very small number of them and yep I wouldn’t work with them again.
great blog even if your not a chem nut some of the shit he explains is so outside the realms
of normal life that is a great read for anyone.
