Safety Practices
40
•
Disconnect the instrument from all voltage sources before opening it for any
adjustment, replacement, maintenance, or repair. If afterwards, the opened
instrument must be operated for further adjustment, maintenance, or repair,
this must only be done by a qualified person who is aware of the hazards
involved.
•
Whenever it is possible that the instrument is no longer electrically safe for use,
make the instrument inoperative and secure it against any unauthorized or
unintentional operation. The electrical safety of the instrument is likely to be
impaired if, for example, the instrument shows visible damage; has been
subjected to prolonged storage under unfavorable conditions; or has been
subjected to severe stress during transportation.
High Temperatures
The torch components remain hot for some time after the plasma has been shut off.
Allow sufficient time for these items to cool to room temperature before you handle
them.
Hot Exhaust Gases
When the plasma is on, hot gases are vented through the chimney above the sample
compartment. An efficient ventilation system must be provided. In addition, avoid
this area of the instrument to prevent burns.
Safe Use of Drain Systems
For safe operation of the system, the pumped drain system should be properly
installed.
Never place the vessel in an enclosed cabinet. Doing so could result in
!
a build-up of hazardous gases, which may result in a serious explosion or
fire.
Warning
Never use a glass drain vessel. A glass drain vessel may break and spill
flammable, toxic, or corrosive liquids.
