Protective Earth
Closing the Instrument Panels and Hoods
Close the instrument hoods before starting the plasma. Because the
instrument can be optimized entirely via computer, there is no need to open
the front and side panels or hood after the plasma is ignited. In addition, a
safety interlock shuts off the plasma if the hood is lifted.
Wearing Safety Glasses
WARNING
Connecting the Agilent 7500 ICP-MS to a power source that is not equipped with a
protective earth contact creates a shock hazard for the operator and can damage the
instrument. Likewise, interrupting the protective conductor inside or outside the
Agilent 7500 ICP-MS or defeating the power cord ground creates a shock hazard for
the operator and can damage the instrument.
WARNING
The instrument's external covers shield the operator from internal hazards while the
instrument is in operation. Exposure to high voltage and radio frequency radiation
from the RF power supply is present and can be very dangerous.
WARNING
The Agilent 7500 provides a protective tinted window for viewing the plasma during
operation. Your eyes can still be exposed to ultraviolet rays if you look at the plasma
directly through the hole on the left side of the left-hand hood. When operating the
instrument, always wear safety glasses prescribed for viewing ultraviolet rays (UV
approved). Direct viewing of ultraviolet rays without protection causes permanent
blindness or vision impairment.
Safety glasses will also protect your eyes from hazardous liquids. Wear safety
glasses whenever preparing or handling samples, maintaining the instrument, or
emptying the drain vessel.
