Hazards with electrothermal atomization

Toxic products:
Toxic metal vapors, ozone, etc., can be generated by the system, depending on the
type of analyses being performed.

You must provide an efficient laboratory ventilation system to remove toxic
products generated during instrument operation.

If you use nitrogen as the inert gas, toxic cyanogen gas (CN)
when the furnace temperature is above 2300 °C.
High temperatures:
The HGA graphite furnace can generate temperatures of up to 3000 °C

To avoid serious burns, never touch the graphite components until the furnace
has cooled to room temperature.

Do not attempt to inject a sample into the graphite tube when the furnace is
hot. You may be subjected to fumes from the sudden vaporization of the
sample, and may damage the pipet.
UV radiation:
The graphite furnace emits ultraviolet radiation when it is heated to
incandescence.

Never directly view the graphite furnace unless you are wearing UV-
absorbing glasses.
