5.HAZARDS IDENTIFICATION

Classification

High pressure gas

Hazard

Oxidative

Long term inhalation of oxygen at a high concentration may adversely influence
humans.


6.HANDLING AND STORAGE

High temperature may increase a risk for rupture of cans. Do not store in a place
with more than 40°C, e.g. under direct sunlight, in a cal' (on a dashboard / seat),
neal' an open flame 01' heating appliance.
Oxygen increases the susceptibility of substances to burn. Store separately from
oils, fats, and combustible substances.
Do not use under a condition of high temperatures associated with electric heatCl;
stove, open flame, etc.
BefOl'e disposal, keep the button pushed down in the open'air far from any ignition
source until the blowing'out sound disappears, to make the container empty.


7.FIRST AID MEASURES

Eye Contact

Exposure to oxygen at the atmospheric pressure does not require any medical treatment. If getting a blowing out gas in eye(s), cool the eye(s), and call an ophthalmologist.

Skin Contact

Exposure to oxygen at the atmospheric pressure does not require any medical treatment. If getting a blowing out gas on skin, cool the skin, and call a physician

Inhalation

Inhalation of a gas containing oxygen at 25 v/v% 01' more at more than the atmospheric pressure may be hazardous. Decreased oxygen partial pressure is effective such patients, excepting those with pneumonia.

Ingestion

The product is gaseous under normal temperature and pressure. Ingestion is unlikely under normal usage.


8.FIRE FIGHTING MEASURES

Fire Fighting

The product, oxygen, increases the susceptibility of substances to burn, i.e. additional supply of oxygen enhances the magnitude of fire. For effective fire fighting, cut off the oxygen supplies to fire.
Oxygen accelerates combustion. Many of substances which are not combustible in normal air burn under a condition of higher oxygen contents. Take away
surroundings at the fire risk.
Exposure of a can to open flame may cause increased internal pressure and then rupture of the can. Extinguish first a fire near the product to cool the product at the fire risk by water"spray from up-wind.

Extinguishing Media

Water, dry powdel' and carbon dioxide. However, dry powder and carbon dioxide are not effective when oxygen blows out from cans.


9.ACCIDENTAL RELEASE MEASURES

Take off all ignition sources from the leaked site.
Ventilate well to decrease a fire risk.
Take off combustible materials such as wood, paper, oils, etc.

10.EXPOSURE CONTROLS I PERSONAL PROTECTION

Control Limit Value

Control the oxygen content between 18 v/v% and 25 v/v% in air for general workplaces, and at 22 v/v% or less for work place with fire

Occupational Exposure Limit

ACGIH (TLV-TWA) : Not determined

Engineering measures

In case of indoor workplace, use away from combustible materials under well ventilation.

Protective equipment

Nothing speciaL Use general one.


11.HAZARD INFORMATION

Flash point

Not applicable

Ignition point

Not applicable

Explosive limit

Not applicable

Stability and Reactivity
(Burning susceptibility)

Increase in oxygen content results in decreased ignition points, and increased burning velocity, flame temperature and flame length. Keep away from organic matters or other combustible articles.
Under oxygen'rich conditions, even a minor ignition source may produce rapid combustion of cloths.
Most of materials which are noncombustible or flame-resistant under normal'air conditions may burn in oxygen only.

Dangerous substances in
mixed touch

Alkaline metals, benzoic acid (pulverized), carbon disulfide, fibers, hydrogen with catalyst, acetone, acetylene, alcohols, oils, and fats.

Corrosivity

Accelerates corrosiveness of metals with water.


12.TOXICOLOGICAL INFORMATION

Acute oral toxicity

...

Acute inhalation toxicity

For short-term inhalation, the upper safety limit concentration is determined as 46 v/v% based on symptoms of intoxication. Excessive inhalation causes decrease in cellular oxidase activity that leads to generalized epileptic convulsion, lip convulsion, dizziness, l'epulsion, respiration discomfort, muscle spasm, confusion, auditory hallucination, visual impairment, toe-pain, etc.
For long-term inhalation, the upper safety limit concentration is determined as 36 v/v% based on symptoms of intoxication. Safety concentrations are
in a range of 18-25 v/v%.
An oxygen concentration below this range induces oxygen deficiency diseases.

Irritation

Not irritative

Sensitization

Not sensitizing

Mutagenicity

Not mutagenic

Subchronic toxicity

None


13.ECOLOGICAL INFORMATION

Fish toxicity

Not containing a substance listed in "Specially Designated Chemical Substances Class 1 or 2", The Law Concerning Examination and Regulation of Manufacture, etc. of Chemical Substances, Japan

Partition coefficient

Not containing a substance listed in "Specially Designated Chemical Substances Class 1 or 2", The Law Concerning Examination and Regulation of Manufacture, etc. of Chemical Substances, Japan


14.TRANSPORTATION INFORMATION

Refer to Section "HANDLINGAND STORAGE".
Confirm no leakage before loading. Carefully load the goods to prevent from possible damages caused by over-turning, falling-down, etc. during transportation. Keep temperatures of the goods below 40°C during transportation.


15.REGULATORY INFORMATION

High Pressure Gas Safety Law, Japan

Applicable to the exempted items (high pressure gas)

Ship Safety Law, Japan

Dangerous substance (high pressure gas)
