3. HAZARDS IDENTIFICATION
Emergency Overview
Extremely cold liquid and gas under pressure.
Direct contact with liquid can cause frostbite.
May react violently with combustible materials.
Keep oil, grease, and combustibles away.
Potential Health Effects
Inhalation : Breathing 75% or more oxygen at atmospheric pressure for more than a few
hours may cause nasal stuffiness, cough, sore throat, chest pain and breathing
difficulty. Breathing pure oxygen under pressure may cause lung damage and
also central nervous system effects. Breathing 75% or more oxygen at
atmospheric pressure for more than a few hours may cause nasal stuffiness,
cough, sore throat, chest pain and breathing difficulty. Breathing pure oxygen
under pressure may cause lung damage and also central nervous system
effects.

Ingestion : Ingestion is not considered a potential route of exposure.
Exposure Guidelines
Primary Routes of Entry : Inhalation
Eye and skin contact.
Target Organs : None.
Aggravated Medical Condition
If oxygen is administered to persons with chronic obstructive pulmonary disease, raising the oxygen
concentration in the blood depresses their breathing and raises their retained carbon dioxide to a dangerous
level. None.
4. FIRST AID MEASURES
Eye contact : In the case of contact with eyes, rinse immediately with plenty of water and
seek medical advice.
Skin contact : In case of contact, immediately flush eyes or skin with plenty of water for at
least 15 minutes while removing contaminated clothing and shoes. Wash frost-
bitten areas with plenty of water. Do not remove clothing. As soon as practical,
place the affected area in a warm water bath- which has a temperature not to
exceed 40 掳C (105 掳F). Cover wound with sterile dressing.
Ingestion : Ingestion is not considered a potential route of exposure.
Inhalation : Consult a physician after significant exposure. Move to fresh air.
5. FIRE-FIGHTING MEASURES
Suitable extinguishing media : All known extinguishing media can be used.
Use extinguishing media appropriate for surrounding fire.
Specific hazards : Combustibles in contact with liquid oxygen may explode on ignition or impact.
Some materials which are noncombustible in air may burn in the presence of
an oxidizer. Contact with organic and most inorganic materials may cause fire.
Vapor cloud may obscure visibility. Keep area evacuated and free from ignition
sources until any spilled liquid has evaporated. (Ground free from frost). Move
away from container and cool with water from a protected position. Do not
direct water spray at container vent. If possible, stop flow of product.
Special protective equipment : Wear self contained breathing apparatus for fire fighting if necessary. Fire
for fire-fighters resistant clothing may burn and offer no protection in oxygen rich atmospheres.
Further information : Some materials that are noncombustible in air will burn in the presence of an
oxygen enriched atmosphere (greater than 23%). Fire resistant clothing may
burn and offer no protection in oxygen rich atmospheres.

Personal precautions : Clothing exposed to high concentrations may retain oxygen 30 minutes or
longer and become a potential fire hazard. Stay away from ignition sources.
Evacuate personnel to safe areas. Ventilate the area. Monitor oxygen level.
Spill will rapidly vaporize forming an oxygen rich vapor cloud. Gas/vapor
heavier than air. May accumulate in confined spaces, particularly at or below
ground level. Personnel who have been exposed to high concentrations of
oxygen should stay in a well-ventilated or open area for 30 minutes before
going into a confined space or near an ignition source.
Methods for cleaning up : Ventilate the area. Keep area evacuated and free from ignition sources until
any spilled liquid has evaporated. (Ground free from frost).
Additional advice : Increase ventilation to the release area and monitor oxygen level.
7. HANDLING AND STORAGE
Handling
All gauges, valves, regulators, piping and equipment to be used in oxygen service must be cleaned for oxygen
service. Oxygen is not to be used as a substitute for compressed air. Never use an oxygen jet for cleaning
purposes of any sort, especially clothing, as it increases the likelihood of an engulfing fire. Know and understand
the properties and hazards of the product before use. Only experienced and properly instructed persons should
handle compressed gases. Before using the product, determine its identity by reading the label. Do not remove
or deface labels provided by the supplier for the identification of the cylinder contents. Before connecting the
container, check the complete gas system for suitability, particularly for pressure rating and materials. Before
connecting the container for use, ensure that back feed from the system into the container is prevented. Close
container valve after each use and when empty, even if still connected to equipment. Never attempt to repair or
modify container valves or safety relief devices. Damaged valves should be reported immediately to the
supplier. If user experiences any difficulty operating cylinder valve discontinue use and contact supplier. Do not
remove or interchange connections. Prevent entrapment of cryogenic liquid in closed systems not protected with
relief device. When moving cylinders, even for short distances, use a cart (trolley, hand truck, etc.) designed to
transport cylinders. When doubt exists as to the correct handling procedure for a particular gas, contact the
supplier. Employ suitable pressure regulating devices on all containers when the gas is being emitted to
systems with lower pressure rating than that of the container. Do not subject containers to abnormal mechanical
shocks which may cause damage to their valve or safety devices. Only transfer lines designed for cryogenic
liquids shall be used. Use only with equipment cleaned for oxygen service and rated for cylinder pressure.
Never permit oil, grease, or other readily combustible substances to come into contact with valves or containers
containing oxygen or other oxidants. All vents should be piped to the exterior of the building.
Storage
WARNING! Do not change or force fit connections. Always keep container in upright position. Containers should
be stored in a purpose build compound which should be well ventilated, preferably in the open air. Do not allow
storage temperature to exceed 50掳C (122掳F). Full containers should be stored so that oldest stock is used first.
Do not store in a confined space. Full and empty cylinders should be segregated. Store containers in location
free from fire risk and away from sources of heat and ignition. Return empty containers in a timely manner.
Stored containers should be periodically checked for general condition and leakage. Protect containers stored in
the open against rusting and extremes of weather. Containers should not be stored in conditions likely to
encourage corrosion. Cryogenic containers are equipped with pressure relief devices to control internal
pressure. Under normal conditions these containers will periodically vent product. Where necessary containers
containing oxygen and oxidants should be separated from flammable gases by a fire resistant partition.

Engineering measures
Natural or mechanical to prevent oxygen-enriched atmospheres above 23% oxygen.
Personal protective equipment
Respiratory protection : Not required for properly ventilated areas.
Hand protection : Loose fitting thermal insulated or leather gloves.
Work gloves are recommended when handling cylinders.
Gloves must be clean and free of oil and grease.
The breakthrough time of the selected glove(s) must be greater than the
intended use period.
Eye protection : Protect eyes, face and skin from liquid splashes.
Safety glasses recommended when handling cylinders.
Skin and body protection : Personnel who have been exposed to high concentrations of oxygen should
stay in a well-ventilated or open area for 30 minutes before going into a
confined space or near an ignition source.
Never allow any unprotected part of the body to touch uninsulated pipes or
vessels which contain cryogenic fluids. The extremely cold metal will cause the
flesh to stick fast and tear when one attempts to withdraw from it.
Safety shoes are recommended when handling cylinders.
Special instructions for : Ensure adequate ventilation, especially in confined areas.
