Solarus 950 Owner’s Manual and User’s Guide
Installation Recommendations for Gatan Customers—Flammable and
Oxidizing Gases
Hydrogen Guidance
O
Enclosure/Cabinet:
Store a lecture bottle of hydrogen within a one hour fire
barrier such as a “semiconductor type” rated lecture bottle gas cabinet. Secure
the compressed gas cylinder inside cabinet.
O
Seismic Bracing and Mechanical Integrity:
Ensure that the enclosure is
seismically braced in accordance with applicable Building Codes and that the
distribution line is properly braced between the cabinet and the Solarus 950.
O
Gas Detection:
Install listed and/or approved hydrogen gas monitoring for
the lecture bottle gas cabinet providing both local and remote alarm
annunciation.
O
Distribution System:
Piping, tubing, valves, and fitting shall be compatible
with flammable gases and be of adequate strength and durability to withstand
the pressure expected.
O
Grounding and Bonding:
Provide for appropriate grounding and bonding to
minimize the potential for static electricity buildup.
O
Maintenance and Inspections:
Place safety critical equipment such as flam-
mable gas detection and grounding on a periodic calibration and test schedule.
Oxygen Guidance
O
Compressed gas cylinder:
Secure oxygen compressed gas cylinders to a
fixed object with one or more restraints stored upright with valve end up. Pro-
tect compressed gas cylinder valves from physical damage, by using valve
caps and ensure compressed gas cylinder caps are in place when not in use
O
Distribution System:
Ensure oxygen piping is free from oil residues and for-
eign material. Oil-free and noncombustible materials must be used for leak
testing oxygen lines.
O
Segregation:
Store oxygen compressed gas cylinder separately from incom-
patible materials, such as hydrogen gas. Note: If hydrogen gas cylinder is
located within a 1-hour rated fire barrier such as a semiconductor type gas
cabinet, then adequate segregation is provided. If no enclosure is used for
hydrogen, then the oxygen compressed gas cylinder shall be located at least
20 feet away.
Oxygen Guidance Applicable to both Hydrogen and Oxygen
O
Leak Testing:
Conduct pressure leak testing of delivery piping and associated
fittings prior to introducing hydrogen to the Solarus 950.
