The following safety precautions are for your protec­tion. Before performing installation, operating, or main­tenance procedures read and follow all safety precau­tions in this section and in reference publications. Fail­ure to observe all safety precautions can result in prop­erty damage, personal injury, or possible death. It is
the responsibility of the purchasers of this equipment
to adequately warn the user of the precautions and safe
practices for the use of this equipment and cryogenic
fluids.

SAFETY PRECAUTIONS FOR LIQUID OXYGEN

Oxygen is a colorless, odorless, and tasteless gas that can
be condensed into a liquid at the low temperature of -297°F
(-183°C) under normal atmospheric pressure. Approximately
one-fifth of normal air is oxygen. As a liquid, oxygen is pale
blue in color. Oxygen is non-flammable but vigorously ac­celerates the burning of combustible materials.

Keep Combustibles Away from

Oxygen and Eliminate Ignition Sources

Many substances which do not normally burn in air require
only a slight spark or moderate heat to set them aflame in
the presence of concentrated oxygen. Other substances
which are only moderately combustible in air can burn vio­lently when a high percentage of oxygen is present.

Do not permit smoking or open flame in any area where
liquid oxygen is stored, handled, or used. Keep all organic
materials and other flammable substances away from pos­sible contact with liquid oxygen. Some of the materials that
can react violently with oxygen are oil, grease, kerosene,
cloth, wood, paint, tar , and dirt which contains oil or grease.
Under certain conditions flammable materials which have
become permeated with liquid oxygen are impact sensitive
and can detonate if subjected to shock.

Keep Area and Exterior Surfaces Clean

to Prevent Ignition

As normal industrial soot and dirt can constitute a combus­tion hazard, all equipment surfaces must be kept very clean.
Do not place oxygen equipment on asphalt surfaces, or al­low grease or oil deposits to remain on benches or concrete
surfaces in the vicinity of the oxygen equipment. Use clean­ing agents which will not leave organic deposits on the
cleaned surfaces. Equipment to be used in contact with
liquid oxygen should be handled only with clean gloves or
hands washed clean of oil.

Maintain Adequate Ventilation

Enclosed areas containing oxygen equipment should be ven­tilated to prevent accumulations of oxygen and thereby mini­mize combustion hazards.

Extreme Cold - Cover Eyes and Exposed Skin

Accidental contact of liquid oxygen or cold issuing gas with
the skin or eyes may cause a freezing injury similar to frost­bite. Handle the liquid so that it won’t splash or spill. Protect
your eyes and cover the skin where the possibility of contact
with the liquid, cold pipes and cold equipment, or the cold
gas exists. Safety goggles or a face shield should be worn if
liquid ejection or splashing may occur or cold gas may issue
forcefully from equipment. Clean, insulated gloves that can
be easily removed and long sleeves are recommended for
arm protection. Cuffless trousers should be worn outside
boots or over the shoes to shed spilled liquid. If clothing
should be splashed with liquid oxygen or otherwise saturated
with the gas, air out the clothing immediately, removing it if
possible. Such clothing will be highly flammable and easily
ignited while the concentrated oxygen remains, and should
not be considered safe for at least 30 minutes.

Replacement Parts

Must be Suitable for Oxygen Service

Many materials, especially some non-metallic gaskets and
seals, constitute a combustion hazard when in oxygen ser­vice, although they may be acceptable for use with other cryo­genic liquids. Make no substitutions for recommended spare
parts. Also, be sure all replacement parts are thoroughly
“Cleaned For Oxygen Service” in accordance with Com­pressed Gas Association (CGA) Pamphlet G-4.1 “Cleaning
for Oxygen Service” or equivalent industrial cleaning specifi­cations.

Observe Safety Codes When
Locating Oxygen Equipment

Before locating oxygen equipment, become thoroughly fa­miliar with National Fire Protection Association (NFP A) S tan­dard No. 50, “Bulk Oxygen Systems”, and with all federal,
state and local safety codes. The NFP A S tandard covers the
general principles recommended for the installation of bulk
oxygen systems on industrial and institutional consumer pre­mises.

CAUTION: When installing field fabricated piping,

make certain a suitable safety valve is in­stalled in each section of piping between
shut-off valves.

For more detailed information concerning safety precautions
and safe practices to be observed when handling cryogenic
liquids consult CGA pamphlet P-12 “Handling Cryogenic Liq­uids” available from the Compressed Gas Association, 1235

SAFETY PRECAUTIONS FOR LIQUID NITROGEN

Nitrogen is an inert, colorless, odorless, and tasteless gas
which makes up four-fifths of the air you breathe. Liquid ni­trogen is obtained by cooling air until it becomes a liquid and
then removing the oxygen which makes up the other fifth of
the air. Liquid nitrogen is at a temperature of -320°F (-196°C)
under normal atmospheric pressure.

Extreme Cold - Cover Eyes and Exposed Skin

Accidental contact of liquid nitrogen or cold issuing gas with
the skin or eyes may cause a freezing injury similar to frost­bite. Handle the liquid so that it won’t splash or spill. Protect
your eyes and cover the skin where the possibility of contact
with the liquid, cold pipes and cold equipment, or the cold
gas exists. Safety goggles or a face shield should be worn if
liquid ejection or splashing may occur or cold gas may issue
forcefully from equipment. Clean insulated gloves that can
be easily removed and long sleeves are recommended for
arm protection. Cuffless trousers should be worn outside
boots or over the shoes to shed spilled liquid.

Keep Equipment Area W ell Ventilated

Although nitrogen is non-toxic and non-flammable, it can
cause asphyxiation in a confined area without adequate ven­tilation. Any atmosphere which does not contain enough oxy­gen for breathing can cause dizziness, unconsciousness, or
even death. Nitrogen being colorless, odorless, and taste­less cannot be detected by the human senses and will be
inhaled normally as if it were air Without adequate ventila­tion, the expanding nitrogen will displace the normal air with­out warning that a non-life-supporting atmosphere is present.
Store liquid containers outdoors or in other well ventilated
areas.

Dispose of Waste Liquid Nitrogen Safely

Dispose of waste liquid nitrogen out-of-doors where its cold
temperature cannot damage floors or driveways and where
it will evaporate rapidly . An out door pit filled with clean sand
or gravel will evaporate liquid nitrogen safely and quickly .

CAUTION: When installing field fabricated piping,

make certain a suitable safety valve is
installed in each section of piping be­tween shut-off valves.

For more detailed information concerning safety pre­cautions and safe practices to be observed when
handling cryogenic liquids consult CGA pamphlet
P-12 “Handling Cryogenic Liquids” available from
the Compressed Gas Association, 1235 Jefferson
Davis Highway , Arlington, VA 22202.

NOTE: Argon is an inert gas whose physical prop-

erties are very similar to those of nitrogen.
For handling of liquid argon, follow the safe
practices described for the handling and
use of liquid nitrogen.

Introduction

The bulk tank liquid level monitoring system provided by
Taylor Wharton provides the latest technology for local as
well as remote observation of a bulk tank’s contents. This
system enables an operator to check tank liquid level
from any computer that has Internet access as well as at
the tank site. With its local digital display it is a direct
replacement for the analog differential pressure “Con­tents Gauge” commonly being used. Because wireless
transmission is used and the unit is battery powered, no
external wiring is required. Therefore installation is as
easy as the replacement of the “Contents Gauge.”

The system consists of a differential pressure transmitter,
a local digital display , a cellular transmitter/receiver, and a
database service that is accessed through an Internet
Web site. Solar assisted batteries supply power for long
life. The differential pressure transmitter connects to the
same tank instrument lines as the “Contents Gauge.”
This component comes with 0-325” and 0-600” water
column spans. Every hour the pressure transmitter

senses the tank liquid level by measuring the differential
pressure produced by liquid in the tank. T ransmitter
output is communicated to the tank mounted telemetry
device in the form of a 4 to 20 mA electrical signal. The
hourly readings are locally stored and at least one time
per day they are all transmitted to the database. For local
observation of the current liquid level, a button is de­pressed causing a tank reading to be taken. The tank will
be sampled every 10 seconds for 15 minutes. During a
fill the same button is used and the tank will be sampled
at the same rate for 1 hour.

Figure 1 below shows the general layout of the telemetry
device.
