General
Operation of an Agilent 710/715/720/725 Series ICP Optical Emission
Spectrometer involves the use of compressed gases, high voltage radio frequency
energy and hazardous materials including corrosive fluids and flammable liquids.
Careless, improper or unskilled use of this spectrometer can cause death or
serious injury to personnel, and/or severe damage to equipment and property.
The spectrometer incorporates interlocks and covers that are designed to prevent
inadvertent contact with any potential hazards. If the instrument is used in any
manner not specified by Agilent, this protection provided by the equipment may be
impaired. It is good practice to develop safe working habits that do not depend
upon the correct operation of the interlocks for safe operation. It is essential that
no interlock or cover is bypassed, damaged or removed.
The safety practices described below are provided to help the user operate the
instrument safely. Read each safety topic thoroughly before attempting to operate
the instrument and always operate the spectrometer in accordance with these
safety practices.

Safety Practices and Hazards
8 Agilent 700 Series ICP Optical Emission Spectrometers User’s Guide
Verifying Safe State
The following general safety precautions must be observed during all phases of
operation, maintenance and service of this instrument.
To ensure continued safety of the instrument after maintenance or service
procedures verify the instrument is returned to a safe state for the user. This
includes running performance checks to verify the instruments safety systems are
functioning correctly. Check the general condition of the instrument during
operation for wear or signs of corrosion that are likely to inhibit function or safety.
Failure to comply with these precautions or with specific warnings elsewhere in
this manual violates safety standards of design, manufacture, and intended use of
the instrument. Agilent Technologies assumes no liability for the customer’s
failure to comply with these requirements.
Plasma
The plasma is extremely hot (about 10,000 K) and radiates dangerous levels of
radio frequency (RF) and ultraviolet (UV) energy. The work coil operates at 1,500 V
RMS and about 40 MHz. Exposure to the RF and UV energy can cause severe skin
damage and cataracts of the eyes, while close contact with the operating plasma
can result in severe heat burns to the skin, and an electrical discharge that can
jump a considerable distance and may cause death, severe electric shock or sub-
surface skin burns.
The plasma must never be operated unless:
the torch compartment door is closed, with the locking lever fully latched; and
the space above the chimney is clear of objects.
The shielding around the torch compartment is designed to reduce UV, visible and
RF radiation to safe levels while still permitting easy access to, as well as
installation and viewing of, the torch. The spectrometer has an interlock system
that is designed to extinguish the plasma if either the mains supply fails or the
handle on the torch compartment door is opened. Do not attempt to bypass the
interlock system.
Before opening the torch compartment door, always extinguish the plasma by
pressing F4 on the keyboard or by clicking the ‘Plasma Off’ icon on the ICP Expert
II software toolbar.

Safety Practices and Hazards
Agilent 700 Series ICP Optical Emission Spectrometers User’s Guide 9
The torch and its surroundings remain hot for up to five minutes after the plasma
is extinguished. Touching this area before it has cooled sufficiently may result in
burns. Allow the torch and torch compartment to cool before carrying out any
work in this area, or wear heat-resistant gloves.
The plasma system has been carefully designed to operate safely and effectively
when using torches and related components that conform to Agilent’s design
criteria. Use of non-approved components in the plasma compartment may render
the system inoperative and/or hazardous. It may also invalidate the warranty on
the instrument. Use only torches and related components supplied or authorized
by Agilent.
Heat, Vapors and Fumes
Heat, ozone, vapors and fumes generated by the plasma can be hazardous, and
must be extracted from the instrument by means of an exhaust system. Ensure
that an exhaust system of the appropriate type is fitted (as specified in the Site
Preparation Guide). The system must be vented to the outside air in accordance
with local regulations and never within the building. Regularly check the exhaust
system by smoke test to ensure that the exhaust system is functioning correctly.
The exhaust fan must always be switched on before igniting the plasma.
Compressed Gas Hazards
All compressed gases (other than air) can create a hazard if they leak into the
atmosphere. Even small leaks in gas supply systems can be dangerous. Any leak
(except that of air) can result in an oxygen-deficient atmosphere, which can cause
asphyxiation. The area in which cylinders are stored and the area surrounding the
instrument must be adequately ventilated to prevent such gas accumulations.
Gas cylinders must be installed, stored and handled strictly in accordance with
local safety codes and regulations. Cylinders must be used and stored only in a
vertical position and secured to an immovable structure or a properly constructed
cylinder stand. Move cylinders only by securing them to a properly constructed
trolley.
Use only approved regulator and hose connectors (refer to the gas supplier’s
instructions). Keep gas cylinders cool and properly labeled. (All cylinders are fitted

Safety Practices and Hazards
10 Agilent 700 Series ICP Optical Emission Spectrometers User’s Guide
with a pressure relief device that will rupture and empty the cylinder if the internal
pressure is raised above the safe limit by excessive temperatures.) Ensure that
you have the correct cylinder before connecting it to the instrument.
The primary gas to be used with the spectrometer is argon, which is the
conductive gas for the plasma. Argon or nitrogen can be used as the
polychromator purge gas. Other gases may be required for future options and
accessories. Use only ‘instrument grade’ gases with your spectrometer.
If using cryogenic gases (for example, liquid argon), prevent severe burns by
wearing suitable protective clothing and gloves.
Electrical Hazards
The spectrometer system and some accessories contain electrical circuits,
devices and components operating at dangerous voltages. Contact with these
circuits, devices and components can cause death, serious injury or painful electric
shock. Panels or covers which are retained by screws on the spectrometer and
accessories may be opened only by Agilenttrained, Agilent-qualified or
Agilentapproved field service engineers (unless specified otherwise). Consult the
manuals or product labels supplied with your personal computer (PC), monitor,
printer and water-cooling system to determine which parts are operator-
accessible.
Replace blown fuses with ones of the size and rating shown in the text near to the
fuse holder.
Other Precautions
Use of the spectrometer system and accessories may involve materials, solvents
and solutions which are flammable, corrosive, toxic or otherwise hazardous.
Careless, improper or unskilled use of such materials, solvents and solutions can
create explosion hazards, fire hazards, toxicity and other hazards that can result in
death, serious personal injury or damage to equipment.
Operation of an ICP-OES involves analysis of solutions that have been prepared in
or digested with acids, or in some cases, samples that have been prepared in
organic solvents.
