GENERAL PRECAUTIONS FOR HANDLING AND STORING HIGH

PRESSURE GAS CYLINDERS

Edited from selected paragraphs of the Compressed Gas Association's "Handbook of Compressed

Gases" published in 1981

Compressed Gas Association

1235 Jefferson Davis Highway

Arlington, Virginia 22202

Used by Permission

1. Never drop cylinders or permit them to strike each other violently.

2. Cylinders may be stored in the open, but in such cases, should be protected against extremes of

weather and, to prevent rusting, from the dampness of the ground. Cylinders should be stored in the

shade when located in areas where extreme temperatures are prevalent.

3. The valve protection cap should be left on each cylinder until it has been secured against a wall or

bench, or placed in a cylinder stand, and is ready to be used.

4. Avoid dragging, rolling, or sliding cylinders, even for a short distance; they should be moved by using a

suitable hand-truck.

5. Never tamper with safety devices in valves or cylinders.

6. Do not store full and empty cylinders together. Serious suckback can occur when an empty cylinder is

attached to a pressurized system.

7. No part of cylinder should be subjected to a temperature higher than 125

F (52

C). A flame should

never be permitted to come in contact with any part of a compressed gas cylinder.

8. Do not place cylinders where they may become part of an electric circuit. When electric arc welding,

precautions must be taken to prevent striking an arc against the cylinder.

SECTION 1

DESCRIPTION AND SPECIFICATIONS

1-1 OVERVIEW

The Model 340 Trace Moisture Analyzer

automatically and continuously measures water

vapor concentrations, up to a maximum of 1000

ppm, in a gaseous sample stream. The

determination is based on the simultaneous

absorption and electrolysis of water. The

instrument has a wide range of applications, in

monitoring many gases used in manufacturing

processes. (Suitable and unsuitable sample

gases are listed in Section 1-3, page 1-4.)

Permissible sample pressure range for the

standard instrument is 10 to 100 psig. Optional

sampling accessories permit monitoring gas

streams at atmospheric or sub-atmospheric

pressures.

The analyzer provides direct readout on a front

panel meter and a selectable output for an

accessory potentiometric recorder. With all AC

operated versions of the analyzer, a selectable

output for a current type recorder is obtainable

through use of an optional plug in the circuit

board.

1-2 INSTRUMENT CONFIGURATIONS

1-3 SAMPLE GASES

WARNING

POSSIBLE EXPLOSION HAZARD

This analyzer is of the type capable of

analysis of sample gases which may be

flammable. If used for analysis of such

gases, the detection section of the ana-

lyzer must be either in an explosion proof

enclosure suitable for the hazardous clas-

sification of the gas , or, protected by a

continuous dilution purge system in ac-

cordance with Standard ANSI /N FPA-496

-1986 (Chapter 8) or IEC Publication

79-2-1983 (Section Three).

If explosive gases are introduced into this

analyzer, the sample containment system

must be carefully leak checked upon in-

stallation and before initial startup, during

routine maintenance and any time the in-

tegrity of the sample containment system

is broken, to ensure that the system is in

leak proof condition. Leak check instruc-

tions are provided in Section 4-1b on page

4-3.

Internal leaks resulting from failure to ob-

serve these precautions could result in an

explosion causing death, personal injury

or property damage.

Determination of whether a sample stream of

a particular composition is suitable for

monitoring depends on its compatibility with

the construction materials in a) the detector

cell, and b) the instrument flow system. In all

instruments, the detector cell utilizes a thin

film of phosphorous pentoxide (P

) on

rhodium electrodes. Depending on the

intended application of a given instrument

version, its internal flow system is constructed

of either stainless steel (for corrosion

resistance) or brass (for non-corrosive sample

gases only).

a. Suitable Sample Gases

Elemental Gases

Argon, Helium, Neon, Nitrogen, Oxygen,

Hydrogen.

Inorganic Gaseous Mixtures and

Compounds

Air, Carbon Dioxide, Carbon Monoxide,

Sulphur Dioxide, Sulphur Hexafluoride.

Organic Gaseous Compounds

Butane, Ethane, Freon 12 , Methane,

Propane, Halogenated Hydrocarbons.

b. Unsuitable Sample Gases

Gases that react with P206 to produce

additional water

Example: alcohols, HF.

Gases that react with construction

materials of the instrument

Gases that react with P

to alter

required absorption characteristics of

the P

film

Examples: ammonia, amines.

Gases that polymerize to form a solid

or liquid phase (they gradually

desensitize the detector cell by coating

or clogging)

Example: Unsaturated hydrocarbons -

alkynes, alkadienes and alkenes.

Gases that contain particulate solid or

liquid materials such as dust and dirt

found in furnace atmosphere gases.

These must be avoided or filtered out

upstream; oil mist or dust from some

types of dryers can clog the detector cell

or desensitize the P

film by forming a

layer over the film.
