Graphic Examples of What Not To Do:

oil bath
This oil bath was run overnight at a much too high temperature! Soot was everywhere on the ceiling of the fume hood. Check the temp limits of the type of oil you are using. A saturated paraffin oil is only good to about 200 °C; for temperatures up to 300 °C, a silicone oil should be used. Care must be taken with hot oil baths not to generate smoke or you risk the oil to burst into flames…

sodium in still
This is a dollop of liquid sodium on the bottom of a dried-out THF still! No running of this still overnight (or if you are out of the lab for extended periods of time)! No running it without heat set above the set point indicated. No running it without the automated power cut-off when the cooling fails!

quench1
Image from a mishap in the NMR lab at University of Illinois, Urbana–Champaign. Do not bring ferrous materials near the 5 Gauss line (indicated on the floor) of the spectrometers! Cards with magnetic strips (credit and ATM cards) cellular phones, laptops and mechanical watches should also remain outside the 5 Gauss perimeter.
