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:
|
| Remove 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.

combustion. |
|
|
| Extinguishing media:
|
| Use appropriate extinguishing
media for surrounding fire. |
|
| Special procedures:
|
| Self-contained breathing
apparatus required. |
| Firefighters should wear the
usual protective gear. |

| 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. |
|

|
|
