Hazards with Flame Atomization
This section contains a summary of the hazards associated with the flame atomization technique.
For more detailed information see the remaining sections in this safety chapter.
High temperatures
The flame can generate temperatures of up to 2800 °C.
WARNING
To avoid serious burns, never touch the burner head until it has cooled
to room temperature.
Toxic products
•
Toxic combustion products can be generated by the system, depending on the type of
analyses being performed. You must provide an efficient exhaust venting system to
remove toxic products generated during instrument operation.
•
Combustion products may vary with the analysis of each sample. Acetylene (less than 1
liter) is released during the bleeding of the gas box prior to shutdown. An exhaust venting
system is always required to remove those gases which are generated during the normal
operation of the instrument.
•
The materials in sample and reagent containers, and material that you collect in waste
containers may include small amounts of toxic substances that were used in the analyses.
You may have to dispose of these as hazardous waste.
UV radiation
You should be aware of the health hazard presented by UV radiation.
Always wear UV-absorbing eye protection when viewing:
•
The flame, especially the nitrous oxide-acetylene flame.
•
Hollow cathode or electrodeless discharge lamps.
•
The deuterium background correction lamp.
•
Keep the atomizer compartment door closed when the flame is burning and never directly
view the flame unless you are wearing UV-absorbing glasses.
