ment backplate) and the power plug disconnected from the mains if there is any in-
terference with the electric components.
3.7.4 Safety instructions for compressed gas containers and
systems
The carrier gas (synthetic air and/or oxygen) is taken from compressed gas containers or
local compressed gas systems. The required purity of the carrier gas must be ensured (→
see chapter "Technical data" p.4)!
Work on compressed gas containers and systems must only be carried out by individuals
with specialist knowledge and experience with compressed gas systems.
The following has to be observed:
For gas cylinder or gas plant operation, the safety instructions and guidelines which
are valid at the operating location must be strictly complied with.
High pressure hoses and pressure reducers may only be used for the assigned gas-
es.
Pipes, hoses, screw connections and pressure reducers for oxygen must be kept
free from grease.
All pipes, hoses and screw connections must be checked regularly for leaks and ex-
ternally visible damage. Leaks and damaged must be repaired without delay.
Prior to inspections, service and repairs, the valves must be closed and the analyzer
vented!
After successful repair and service of the components of the compressed air con-
tainers or system, the analyzer must be checked for sound operation prior to re-
commissioning!
Independent assembly and installation are not permitted!
3.7.5 Handling of auxiliary and operating materials
The operator is responsible for the selection of substances used in the process as well as for
their safe handling. This is particularly important for radioactive, infectious, poisonous, corro-
sive, combustible, explosive and otherwise dangerous substances.
When handling dangerous substances, local safety codes and guidelines must be observed.
The following general notes do not replace the specific local regulations or the regulations in
the EC safety data sheets of the manufacturers for the auxiliary and operating materials.
The following has to be observed:
The relevant regulations and the notes in the EC safety data sheets of the manufac-
turers have to be observed and complied with regards to storage, handing, use and
disposal for all auxiliary and operation materials used during operation or mainte-
nance of the analyzer.

Auxiliary and operation materials may never be placed in containers or vessels for
food. The approved containers for the relevant material are to be used and these
have to be labeled accordingly. The notes on the labels have to be observed!
Protective goggles and rubber gloves have to be worn when handing reagents. The
notes on the labels have to be observed.
The regulations and notes on the safety data sheets for the handling of orthophos-
phoric acid (H3PO4) or hydrochloric acid (HCl) have to be observed!
The catalysts supplied by the manufacturer (platinum catalyst multi N/C or special
catalyst multi N/C) must be treated with the usual caution when handling chemicals.
Biological samples have to be handled according to local guidelines regarding the
handling of infectious material.
Caution when handing quartz glass and glass parts. Risk of broken glass and there-
fore risk of injury!
Avoid dust formation and inhalation of dust when handing the quartz glass wool dur-
ing filling of the combustion tube.
Auxiliary and operating materials as well as their containers may not be disposed of
in domestic waste or enter the sewage system or the soil. The applicable regulations
for disposal of these materials must be meticulously observed.
Ensure good room ventilation in working rooms.
3.7.6 Safety instructions - service and repair
The analyzer is to be serviced by the Analytik Jena AG customer service department or its
authorized and trained specialist personnel.
Independent servicing can misadjust or damaged the analyzer. Therefore, the operator may
only carry out the tasks listed in the chapter "Service and care".
The following has to be observed:
The exterior of the analyzer may only be cleaned with a damp, not dripping, cloth af-
ter the analyzer has been switched off.
Any service and repair work to the analyzer may only be carried out in the switched-
off condition (unless stated otherwise).
Service tasks and the replacement of system components (removal of the combus-
tion tube, catalyst replacement) must only be carried out after a sufficiently long cool-
ing down phase.
Prior to commencing servicing or repair tasks, the energy and gas supplies must be
disconnected and the analyzer must be vented!
Only use original accessories and original replacement parts from Analytik Jena AG.

3.8 Behavior in an emergency
The analyzer must be switched off at the power switch (on the equipment backplate) and the
power plug must be disconnected from the mains in the case of dangerous situations or ac-
cidents.
Because a rapid response can save lives during an emergency, the following has to be en-
sured:
The operating staff must be familiar with the location of safety equipment, accident
and danger alarms and first aid and rescue equipment, and also have an under-
standing of how they are used.
The operator is responsible for ensuring that all operating staff is appropriately
trained.
All first aid equipment (first-aid kit, eyewash bottles, stretcher, etc.) as well as fire-
fighting equipment (fire extinguishers) must be within reach and easy to access. All
equipment has to be in a sound condition and should be checked regularly.
