HAZARDS
5.1 LASER SAFETY
The Triple Transducer Module and Bar-Code Reader contain lasers. A laser is a unique light
source that exhibits characteristics different from conventional light sources. The safe use of
the laser depends upon familiarity with the instrument and the properties of coherent, intense
beams of light. The beam can cause eye damage and instrument damage. There is enough
power from the laser to ignite substances placed in the beam path, even at some distance. The
beam might also cause damage if contacted indirectly from reflective surfaces (specular
reflection). The lasers on the LH 700 Series are covered by protective housings that are held
in place by tamper-proof screws.
All service and maintenance of the laser must be done at the Beckman Coulter factory by
trained personnel. If removal is required, it must be done by a Beckman Coulter
Representative.
5.2 RADIATION HAZARDS
In the design and manufacture of the LH 700 Series, Beckman Coulter Inc. has complied with
the requirements governing the use and application of a laser as stipulated in regulatory
documents issued by the
r
U.S. Department of Health and Human Services, and
r
Center for Devices and Radiological Health (CDRH).
In compliance with these regulatory documents, every measure has been taken to ensure the
health and safety of users and laboratory personnel from the possible dangers of laser use.
5.3 LASER WARNING LABELS
CDRH-approved labels are placed near or on those covers that, when removed, might expose
laser radiation. Figure 5.1 shows the laser cover and the protective housing cut away. This
illustration is intended only to show you what the system looks like, in compliance with
CDRH. See Figure 5.1 for the labels and their locations on the laser head. See Figure 5.2 for
the label location on the beam cover between the laser head and the sampling compartment.
Figure 5.1 and Figure 5.2 show certification labels.
WARNING Possible harm to operator. Do not use any controls, make any adjustments, or perform any
procedures other than those specified herein. To do so may result in hazardous radiation exposure.
WARNING Possible harm to operator. Do not attempt to remove the laser or to open it. Failure to comply
can result in hazardous radiation exposure. If removal is required, it must be done only by a Beckman
Coulter Representative.
WARNING Possible harm to operator. This instrument contains components dangerous to the operator. If
any attempt has been made to defeat a safety feature, or if this instrument fails to perform as listed in this
manual, disconnect power and call your Beckman Coulter Representative.
