Emergency Overview:
|
| Oxygen
gas is colorless, odorless, non-toxic cryogenic liquid or
colorless, odorless, oxidizing gas. 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:
|
| No adverse effects expected.
|
|
| Skin contact:
|
| No adverse effects expected.
.
|
|
| 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. |

| 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. |
| Cylinders are equipped with
temperature and pressure relief devices but may still rupture
under fire conditions. |
|
|
|
|
| Leak/Spill:
|
| Evacuate all non-essential
personnel. |
| Stop leak without risk.
|
| Wear
gloves and goggles |
Use a self-contained
breathing apparatus.
|
| Ventilate
area. Monitor the surrounding area for Oxygen level |
|
|
|
|
| Handling procedures
and equipment: |
| Protect
system components against physical damage. |
| 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 Gaseous Oxygen. Protect
cylinders against physical damage. Store in cool, dry,
well-ventilated, fireproof area, away from flammable materials
and corrosive atmospheres. Store away from heat and ignition
sources and out of direct sunlight. Do not store near
elevators, corridors or loading docks. Do not allow area where
cylinders are stored to exceed 52°C (125°F).
Move cylinders with a suitable hand-truck. Do not drag, slide
or roll cylinders. Do not drop cylinders or permit them to
strike each other. Secure cylinders firmly. Leave the valve
protection cap in-place (where provided) until cylinder is
placed into service and after it is taken out of service.
Use designated CGA fittings and other
support equipment. Do not use adapters. Do not heat cylinder
by any means to increase the discharge rate of the product
from the cylinder. Use check valve or trap in discharge line
to prevent hazardous backflow into the cylinder. Do not use
oils or grease on gas-handling fittings or equipment.
After use, close main
cylinder valve. Replace valve protection cap (where provided).
Mark empty cylinders "EMPTY". |
