Emergency Overview:
|
|
Oxygen gas is
colorless, odorless, non-toxic cryogenic liquid
or colorless, odorless, oxidizing gas.
Contact with
oxygen liquid, its cold vapors or cold piping
can cause frostbite and cryogenic burns to
exposed tissue. Liquid releases will quickly
vaporize to gas.
The chief
physical hazard associated with releases of the
gas is its oxidizing power which can greatly
accelerate the burning rate for both common and
exotic combustible materials. Emergency
personnel must practice extreme caution when
approaching oxygen releases because of the
potential for intense fire.
The primary
health hazard at atmospheric pressure is
respiratory system irritation after exposure to
high oxygen concentrations. Maintain oxygen
levels in air above 19.5% and below 23.5%. While
up to 50% oxygen can be breathed for more than
24 hours without adverse effects, high
concentrations in open air accelerate combustion
and increase the risk of fire and explosion of
combustible or flammable materials. |
|
|
Route of entry: |
|
Inhalation, skin
and eye contact. |
|
|
Effects of acute
exposure
|
|
|
Eye contact: |
|
Can cause
frostbite (liquid form). |
|
No adverse
effects from gas. |
|
|
Skin contact: |
|
Can cause
frostbite (liquid form). |
|
No adverse
effects from gas. |
|
|
Inhalation: |
|
May cause
breathing difficulty. |
|
Prolonged
exposure to high oxygen levels (>75%) can cause
central nervous system depression:
signs/symptoms can include headache, dizziness,
drowsiness, poor coordination, slowed reaction
time, slurred speech, giddiness and
unconsciousness. |
|
May cause
coughing and chest pain. |
|
May cause lung
damage. |
|
May cause
soreness of the throat. |
|
|
Ingestion: |
|
Not a likely
route of exposure. |
|
|
Effects of chronic
exposure:
|
|
|
Reproductive effects:
|
|
Oxygen
deficiency during pregnancy has produced
developmental abnormalities in humans and
experimental animals. |
|
|
|
|
|
Skin contact: |

contaminated clothing. |
|
Treat for
frostbite if necessary by gently warming
affected areas. |

Consult a
physician. |
|
|
Eye contact: |
|
Immediately
flush eyes with plenty of water for at least 15
minutes. |
|
Consult an
ophthalmologist. |

Explosion Data
|
|
|
Sensitivity to
mechanical impact:
|
|
Avoid impact
against container. |
|
|
Explosive power:
|
|
Closed
containers may rupture or explode due to
pressure build-up when exposed to extreme heat.
|
|
|
|
|
|
Leak/Spill: |
|
Evacuate all
non-essential personnel. |
|
Stop leak
without risk. |
|
Keep combustible
materials away from spill. |
|
Ventilate.
Eliminate all sources of ignition. |
|
Allow to
evaporate to atmosphere. |
|
Do not walk on
or roll equipment over the spill |
|
Wear gloves and
goggles |
|
Ventilate area.
Monitor the surrounding area for Oxygen level.
|
|
|
|
|
|
Handling procedures
and equipment:
|
Never allow any
unprotected part of the body to touch
uninsulated pipes or vessels that contain cold
fluids. The extremely cold metal of the
container will cause moist flesh to stick fast
and tear when one attempts to withdraw from it.
|
|
Protect system
components against physical damage. Check all
hoses and transfer equipment before filling them
with the liquid. Replace any worn or cut hoses
prior to use.
|
Liquid Oxygen is
extremely cold and is under pressure. A complete
hose failure can result in a large release of
Oxygen and violent movement of the hose and
associated equipment, which may cause severe
injury or death. Special care must be taken when
depressurizing and disconnecting hoses.
|
|
Use adequate
ventilation. |
|
Avoid
inhalation. |
|
Never work on a
pressurized system. |
|
If there is a
leak, close the upstream valve, blow down the
system by venting to a safe place, then repair
the leak. |
|
|
Storage requirements:
|
|
Use storage
containers, piping, valves and fittings designed
for storage and distribution of Liquefied Oxygen
and vaporized (Gaseous) Oxygen. |
