SAFETY SUMMARY

List of WARNING Indications

 Beware of High Voltage!
There is a danger of electric shock due to high voltage of
about 400 V. Touching the socket of the hollow cathode
lamp could result in fatal or serious injury.
Before replacing the lamp, be sure to turn OFF the lamp
current (click the lamp OFF button).
 Beware of Toxic Gas!
Inhalation of toxic gas could be injurious to human health.
Inhaling the vapor emitted from the sample may cause
inflammation of the respiratory tract.
Be sure to operate the ventilating fan to discharge the vapor
emitted from the sample through the exhaust duct.
 Explosion due to Backfiring!
If water is not supplied to the drain trap, there is a danger of
explosion due to backfiring, or ignition due to gas leakage.
Be sure to supply the drain trap with water.
 Explosion due to Acetylide Formation!
If samples containing a large amount of copper, silver or
mercury are atomized, it may generate metal acetylide and
cause explosion due to backfiring with louse noise. Do not
measure samples containing a large amount of copper,
silver or mercury.
