Taylor-Wharton XL-65HP (with dual regulators) - Manual (Page 2)

Pressure Hazard – The containers covered by this literature may contain pressures up to
350 psig (24 bar/2412 kPa). Sudden release of this pressure may cause personal injury
by issuing cold gas or liquid, or by expelling parts during servicing. Do not attempt any
repairs on these containers until all pressure is released, and the contents have been
allowed to vaporize to ensure no pressure buildup can occur.
Extreme Cold-Cover Eyes and Exposed Skin – Accidental contact of the skin or eyes
with any cryogenic liquid or cold issuing gas may cause a freezing injury similar to frost-
bite. Protect your eyes and over your skin when handling the container or transferring
liquid, or in any instance where the possibility of contact with liquid, cold popes and cold
gas may exist. Safety goggles or a face shield should be worn when withdrawing liquid or
gas. Long-sleeved clothing and gloves that can be easily removed are recommended for
skin protection. Cryogenic liquids are extremely cold and will be at temperatures below -
300°F (-184°C) under normal atmospheric pressure.
Keep Equipment Well Ventilated – Although some of the gases used in these contain-
ers are non-toxic and non-flammable, they can cause asphyxiation in a confined area
without adequate ventilation. An atmosphere that does not contain enough oxygen for
breathing will cause dizziness, unconsciousness, or even death. These gasses cannot
be detected by the human senses and will be inhaled normally as if they were air. Ensure
there is adequate ventilation where these gasses are used and store liquid containers
outdoors or only in well ventilated are.
Replacement Parts Must be “Cleaned for Oxygen Service” – Some materials, espe-
cially non-metallic gaskets and seals, can be a combustion hazard if used in oxygen or
nitrous oxide service, although they may be acceptable for use with other cryogenic liq-
uids. Use only Taylor-Wharton recommended spare parts, and be certain parts used on
oxygen or nitrous oxide equipment marked “cleaned for oxygen service”. For information
on cleaning, consult the Compressed Gas Association (CGA) pamphlet G-4.1, “Cleaning
for Oxygen Service” or equivalent industrial cleaning specifications.
Install Relief Valves in Cryogenic Liquid Lines - When installing piping of fill hose
assemblies, make certain a suitable safety relief valve is installed in each section of
plumbing between shut-off valves. Trapped liquefied gas will expand as it warms and may
burst hoses or piping causing damage or personal injury.
The XL-65 and XL-65HP are vacuum-insulated, stainless steel containers designed to
store and transport cryogenic liquid oxygen, nitrogen, argon, carbon dioxide, and nitrous
oxide. Built to DOT 4L standards, these containers may be used for over the road trans-
portation of cryogenic fluids, as well as on-site storage and supply in a wide range of
applications.
As rugged, long holding time, self-contained gas supply systems, these cylinders are
capable of providing continuous flow rates of up to 150 cfh (3.9 cu.m/h) in carbon dioxide
service, up to 110 cfh (2.9 cu.m/h) in nitrous oxide service for the XL-65HP; up to 350 cfh
(9.2 cu.m/h) in either Oxygen/Nitrogen/Argon gas services for both cylinders. The XL-65
and XL-65HP are designed to hold liquid with a relief valve setting of 350 psig (24 bar/2413
kPa) for the XL-65HP and 230 psig (16 bar/158 kPa) for the XL-65 kPa) for the XL-65.
