General Safety Considerations
Components and Functions
The following safety items must be observed to avoid personal injury
and to prevent damage to the ta3000F analyzer. All personnel involved
in installation, operation or service of the analyzer should be thoroughly
familiar with these items. These considerations are in addition to all site
specific safety procedures.
Hydrogen (H
2
) Gas Flow
Since Hydrogen is flammable and can be explosive if confined, do not
operate FID- equipped instruments without an external shut-off valve
on the hydrogen line. Periodically check that the shut-off valve oper-
ates correctly when the FID flame goes out. Also, in FID-equipped
instruments do not provide hydrogen flow unless carrier gas is also
flowing. In any application using hydrogen, be sure to turn off the
supply at its source when removing any portion of the H
2
flow path
or performing service procedures,etc. Should gas flow measurements
through an FID be required, do not measure air and H
2
together. They
should be measured separately to minimize explosion hazard.
Electrical Hazard
Be sure that the top cover is securely in place before operating the
ta3000F analyzer. Since some service procedures require the cover
to be removed while the power is on, be aware that electric shock can
occur. Therefore, only trained or otherwise qualified personnel should
service the analyzer. The analyzer is supplied with a 3-conductor
power cord providing a protective earth ground connection when
plugged into a properly wired receptacle. Proper receptacle grounding
must be verified.
