Caution! Before locating oxygen
equipment, become familiar
with the relevant National Fire
Protection Association (NFPA)
standards for “Bulk Oxygen
Systems at Customer Sites,”
and with all local safety codes.
The NFPA standard (www.nfpa.org) covers general
principles recommended for installing bulk oxygen systems
on industrial and institutional consumer premises.
Caution! To prevent possible tip over, do
not leave tank standing upright
unless it is secured to its
foundation (bolted down).
Transporting and erection of the tank should be performed in
accordance with rigging instructions available from Chart.
Failure to comply with these instructions may result in
serious damage to the container.

attention to the fact that whenever a cryogenic container
is involved in any incident whereby the container or its

function of a container is suspected of abnormal operation.
Good safety practices dictate the contents of a damaged or
suspect container be carefully emptied as soon as possible.
Under no circumstances should a damaged container be left
Incidents which require that such practices be followed

The remainder of this safety bulletin addresses those adverse
environments that may be encountered when a cryogenic
container has been severely damaged. These are oxygen
exposure to inert gases.
Oxygen Decient Atmospheres
Warning! Nitrogen and argon vapors in
air may dilute the concentration
of oxygen necessary to support
or sustain life. Exposure to
such an oxygen decient
atmosphere can lead to
unconsciousness and serious
injury, including death.
The normal oxygen content of air is approximately 21%.
users should exercise suitable precautions.
One aspect of this possible hazard is the response of humans
when exposed to an atmosphere containing only 8 to 12%
immediate with virtually no warning.
When the oxygen content of air is reduced to about 15
an individual breathing the air is mentally incapable of
diagnosing the situation because the onset of symptoms
errors in judgment and confusion can be masked by a state of
