Safety instructions relating to the formation of ozone and toxic vapors
The interaction between the UV radiation from the torch and the surrounding air results
in the formation of a high concentration of toxic gases such as ozone and nitrogen ox-
ides. Additionally, toxic byproducts may escape from the samples and during sample
processing.
Observe the following notes:
The PlasmaQuant PQ 9000 may only be operated with an active exhaust unit.
The exhaust unit must be switched on before igniting the plasma.
2.4.7
Safety instructions relating to compressed gas containers and systems
Observe the following notes:
Argon is taken from compressed gas containers or local liquid gas systems. The re-
quired purity of the gases must be ensured.
Work on compressed gas containers and systems must only be carried out by individ-
uals with specialist knowledge and experience in compressed gas systems.
For compressed gas container or gas plant operation, the safety instructions and
guidelines which are valid at the operating location must be strictly complied with.
High pressure tubes and pressure reducers may only be used for the assigned gases.
Pipes, hoses, screw connections and pressure reducers for oxygen must be kept free
from grease.
All pipes, tubes and screw connections must be checked weekly for leaks and exter-
nally visible damage. Possible pressure losses from closed systems and lines under
pressure must be determined. Leaks and damaged must be repaired without delay.
The gas supply must be closed prior to servicing and repairs!
After successful repair and servicing of the components of the compressed air con-
tainers or system, the device must be checked for sound operation prior to recom-
missioning!
Independent assembly and installation are not permitted!
2.4.8
Handling of samples, auxiliary and operating materials
Observe the following notes:
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, corrosive, combustible, explosive and otherwise dangerous substances.
When handling dangerous substances, local safety codes and guidelines must be ob-
served.
Warnings on the labels must always be observed. Only use clearly marked containers
as well as protective goggles and rubber gloves. Use suitable body protection (coat,
safety glasses and rubber gloves) when handling samples. Ensure sufficient ventila-
tion.
Cleaning with hydrofluoric acid must be carried out in an
exhaust chamber
. When
handling hydrofluoric acid,
rubber aprons, gloves and face masks
must be worn.
