Lino cut chisels- remember to always cut away from yourself!

Scalpels and other knives- remember when cutting cardboard to not slice towards where your thumb joins your hand!

Hot knife- do not attempt to remove melted Mylar from the tip until the knife has cooled down!

Cadmium paints- clean the sink and drying surface of all remnants before you wash your dishes in the same sink!

Turps and other solvents- keep the windows open and when you feel a bit woozy open them a bit more!

I think the most dangerous thing is my own gormless brain
