- Certain equipment, such as this gas chromatograph, have very hot elements
(e.g., the injector). This person is about to burn his left forefinger.
- This person is about to burn his nose on the vertical metallic plate of
this melting point apparatus.
- When removing a thermometer from the melting point apparatus -- LIFT
STRAIGHT UP!
If you attempt to remove the thermometer at an angle, it will snap off. If the mercury bulb falls into the melting point apparatus and breaks, the mercury will vaporize on the hot chamber. Mercury is very toxic, so the entire lab will have to be evacuated.
