Safety Practices and Hazards
10 Agilent Microwave Plasma Atomic Emission Spectrometers User’s Guide
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
MP-AES instrument may render the system inoperative and/or
hazardous. It may also invalidate the warranty on the MP-AES
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 MP-AES 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 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 storage area
must be adequately ventilated and must comply with the rules and
regulations imposed by the local authorities responsible for such use
in the workplace.
Gas cylinders must be 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.
If gases are to be plumbed from a remote storage area to the
instrument site, ensure that the local outlets are fitted with stop
valves, pressure gauges and suitable regulators that are easily
accessible to the instrument operator. The gas outlets must be
provided within 1.5 meters (5 feet) of the MP-AES instrument.
