Hydrogen Gas Tank

TVA2020 Instruction Manual
7-7
The major hazard associated with the handling of hydrogen is flammability.
The following specific rules apply when handling hydrogen:
●
Never use cylinders of hydrogen in areas where flames, excessive heat,
or sparks may occur.
●
Use only explosion-proof equipment and spark-proof tools in areas
where hydrogen is handled.
●
Ground all equipment and lines used with hydrogen.
●
Never use a flame to detect hydrogen leaks — use soapy water.
●
Do not store reserve stocks of hydrogen with cylinders containing
oxygen or other highly oxidizing or combustible materials.
●
Store hydrogen tanks in a well ventilated area.
●
Follow all regulatory safety and labeling precautions when shipping
hydrogen in the TVA2020.
Note
A bleeder assembly is provided in the tool kit to allow the hydrogen
tank to be emptied for common carrier shipment. To use the bleeder,
manually screw the bleeder onto the tank valve and allow the hydrogen to
vent. This process will take about two minutes to complete.
▲
CAUTION
Observe all hydrogen handling procedures listed above.
▲
When transporting the instrument, remove the hydrogen tank and place it
in its normal location in the carrying case.
Use the following procedure to fill the tank.
WARNING
A safe refill operation means there are no hydrogen leaks.
Before any valves are opened, use a wrench to firmly tighten connections to
the hydrogen supply tanks and the tank fill adapter. If escaping hydrogen is
heard during the filling operation, close all valves and correct the leak
before proceeding. Leak test with soapy water or equivalent.
