Safety symbols indicating high voltage inside the ProteinChip SELDI system

cabinet. These labels are located on the exterior of the instrument, near the screws
retaining the side covers.

Warning:

If the equipment is used in a manner other than specified, the

protection provided by the equipment may be impaired. No contact with
hazardous parts or emissions is possible if the instrument panels are kept in
place. It is the user’s responsibility to ensure that untrained persons do not
access the interior. Serious injury or death may result from contact with
components inside the cabinet under single-fault conditions.

The enclosure is an integral part of the safety of this unit. In all cases, the
instrument should be shut down and power removed from the instrument
before removing

any

external cover.

Only personnel aware of the hazards of high voltage and Class 3B laser
radiation should service the reader. The following label should be present near
the safety interlock defeat port and near the safety interlock switches associated
with panels protecting the user from laser radiation:

Laser Radiation

Warning:

The system contains an ultraviolet (UV)-emitting pulsed nitrogen

laser (337 nm, 250 µJ maximum energy/4 ns pulse, 20 Hz maximum pulse
rate). The mass analyzer is a CLASS 1 LASER PRODUCT according to EN 60825:
1993. This means it is safe under reasonably foreseeable conditions of
operation. However, normal operation does not include maintenance or
service. When the enclosure panels and any of the optics covers inside the
instrument are removed, human access to Class 3B laser radiation becomes
possible. Laser safety glasses must be worn when servicing the instrument. The
