18 - MC6-T Safety
Warning: If you use nitrogen, minimize the leak to the
atmosphere and take care of sufficient ventilation. Close the
valve of the nitrogen cylinder, when the system is not in use.
Increase in the percentage of nitrogen in the ambient air may
cause unconsciousness and death without warning. Read
carefully the safety instructions for nitrogen and make sure that
other people in the same space are aware of the danger.
Use of liquid pressure medium is recommended with pressure
measurement modules at higher pressure range. Use water
or suitable hydraulic oil. Check that the used liquid is not
aggressive against the materials used in the transducer or
tubing. When using liquid, minimize the amount of air in the
system to minimize the amount of spilled liquid in case of
leakage.
Warning: Do not use the same tubing with different liquids or
gases.
Check what the local regulations say about construction and
use of pressurized vessels. The regulations normally control
construction and use of systems where the product of the
pressure and volume exceeds a certain limit. The volume of this
system depends on the instrument connected to it.
High pressure gas is dangerous because it can break the
container and the flying splinters may cause injury. Also small
leaks of gas may be dangerous because the high velocity of the
leaking gas jet enables penetration through skin. If a gas bubble
gets into the blood circulation, it can cause death. The leak jet is
particularly penetrative, if some liquid is coming with the gas.
