3. HAZARDS IDENTIFICATION
Physical state: Gas. (COLORLESS GAS; GAS CONDENSES TO A COLORLESS LIQUID)
Emergency overview: Warning!
CONTENTS UNDER PRESSURE.
Do not puncture or incinerate container.
Contact with rapidly expanding gases can cause frostbite.
Routes of entry: Inhalation
Potential acute health effects
Eyes: No known significant effects or critical hazards.
Skin: No known significant effects or critical hazards.
Inhalation: Acts as a simple asphyxiant.
Ingestion: Ingestion is not a normal route of exposure for gases.
Potential chronic health effects: CARCINOGENIC EFFECTS: Not available.
MUTAGENIC EFFECTS: Not available.
TERATOGENIC EFFECTS: Not available.
Medical conditions: Acute or chronic respiratory conditions, as well as disorders involving the "Target
aggravated by overexposure Organs", as listed in Section 3 (Hazard Information), may be aggravated
by overexposure to the components of this gas mixture.
See toxicological Information (section 11) Inhalation In high concentrations may cause asphyxiation.
Symptoms may include loss of mobility or consciousness. Victim may not be aware of asphyxiation. In
high concentrations may cause narcotic effects. Symptoms may include dizziness, drowsiness, nausea,
vomiting, loss of co-ordination, and depression of all the senses. The skin of a victim may have a blue
color. Under some circumstances, death may occur. The effects associated with various levels of
oxygen are as follows:
1
Concentration of Oxygen Symptoms of Exposure
12-16% Breathing & pulse rate increased, muscle coordination disturbed
10-14% Emotional upset, abnormal fatigue, disturbed respiration
6-10% Nausea and vomiting, loss of consciousness
Below 6% Convulsive movements, possible respiratory collapse, and death.
Other Potential Health effects: Contact with cryogenic liquid or rapidly expanding gases (which are
released under high pressure may cause frostbite. Symptoms of frostbite include change in skin color
to white or grayish-yellow. The pain after contact with liquid can quickly subside.
Chronic: There is currently no known adverse health effects linked with chronic exposure to Krypton.
Target Organs: Respiratory System.
4. FIRST AID MEASURES
Remove victim to uncontaminated are a (fresh air) wearing self-contained breathing apparatus as
quickly as possible. In case of contact, immediately flush eyes with copious amounts of water for at
least 15 minutes. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Keep
victim warm and rested. Victim must be taken for medical attention.
No action shall be taken involving any personal risk or without suitable training. If fumes are still
suspected to be present, the rescuer should wear an appropriate mask or a self-contained breathing
apparatus. It may be dangerous to the person providing aid to give mouth-to-mouth resuscitation.
Eye contact: In case of contact, immediately flush eyes with plenty of water for at least 15 minutes.
Get medical attention if irritation occurs.
Skin contact: In case of contact, immediately flush skin with plenty of water. Remove contaminated
clothing and shoes. Wash clothing before reuse. Thoroughly clean shoes before reuse. Get medical
attention. Frostbite: Try to warm up the frozen tissues and seek medical attention.
Ingestion: Do NOT induce vomiting unless directed to do so by medical personnel. Never give anything
by mouth to an unconscious person. Get medical attention if symptoms appear.
ACCIDENTAL RELEASE MEASURES: Personal precautions Evacuate area. Wear self-contained
breathing apparatus when entering area unless atmosphere is proved to be safe. Ensure adequate air
ventilation. Environmental precautions: Try to stop release. Prevent from entering sewers, basements
and work pits, or any place where its accumulation can be dangerous. Clean up methods Ventilate
area.
5. FIRE-FIGHTING MEASURES
Flammability of the product: Non-flammable.
Fire fighting media and instructions: Use an extinguishing agent suitable for surrounding fires.
If involved in fire, shut off flow immediately if it can be done without risk. Apply water from a
safe distance to cool container and protect surrounding area. No specific hazard.
Special protective equipment for Fire fighters: Fire fighters should wear appropriate protective
equipment and self-contained breathing equipment for fire fighters apparatus (SCBA) with a
full-face piece operated in positive pressure mode.
6. ACCIDENTAL RELEASE MEASURES
Personal precautions: Immediately contact emergency personnel. Keep unnecessary personnel away.
Use suitable protective equipment (Section 8). Shut off gas supply if this can be done safety.
Isolate area until gas has dispersed.
Environmental precautions: Avoid dispersal of spilled material and runoff and contact with soil,
waterways, drains and sewers.
7. HANDLING AND STORAGE
Handling: Do not puncture or incinerate container. High-pressure gas. Use equipment rated for cylinder
pressure. Close valve after each use and when empty. Use only properly specified equipment, which is
suitable for this product, its supply pressure and temperature. Contact your gas supplier if in doubt.
Refer to supplier's container handling instructions.
2
Storage: Keep container tightly closed. Keep container in a cool, well-ventilated area.
8. EXPOSURE CONTROLS/PERSONAL PROTECTION
Engineering controls: Use only with adequate ventilation. Use process enclosures, local exhaust
ventilation, or other engineering controls to keep airborne levels below recommended exposure limits.
Personal protection Eyes: Safety eyewear complying with an approved standard should be used when
a risk assessment indicates this is necessary to avoid exposure to liquid splashes, mists or dusts.
Skin: Personal protective equipment for the body should be selected based on the task being
performed and the risks involved and should be approved by a specialist before handling this product.
Respiratory: Use a properly fitted, air-purifying or air-fed respirator complying with an approved
standard if a risk assessment indicates this is necessary. Respirator selection must be based on known
or anticipated exposure levels, the hazards of the product and the safe working limits of the selected
respirator. The applicable standards are (US) 29 CFR 1910.134 and (Canada) Z94.4-93.
Hands: Chemical-resistant, impervious gloves or gauntlets complying with an approved standard should
be worn at all times when handling chemical products if a risk assessment indicates this is necessary.
Personal protection in case of a large spill: A self-contained breathing apparatus should be used to
avoid inhalation of the product. Ensure adequate ventilation. Consult local authorities for acceptable
exposure limits.
