This section describes the general hazards encountered with the ICP-MS instrument
and the safety practices to observe to avoid harm.
The plasma is very hot (>5,000 °C) and radiates dangerous levels of radio-frequency
(RF) and ultraviolet (UV) energy. The work coils operate routinely at 2000 Root Mean
Square Voltage (VRMS) (and even higher at ignition) at 27.12 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 which can jump a considerable distance and cause death, severe
electric shock, or sub-surface skin burns which will not heal.
