3. Hazards Identification
EMERGENCY OVERVIEW
Simple Asphyxiant - This product does not contain oxygen and may cause asphyxia if released in a confined area. Maintain oxygen levels above 19.5%. Contact with product may cause frostbite or freeze burns in exposed tissues. Nonflammable.

Carcinogenicity: -- NTP: No IARC: No OSHA: No
EYE EFFECTS:
Contact with evaporating liquid may cause tissue freezing.
SKIN EFFECTS:
Contact with rapidly evaporating liquid can cause cryogenic "burns" or frostbite. Frostbite effects are a change in color of the skin to gray or white, possibly followed by blistering.
INGESTION EFFECTS:
Ingestion is unlikely. Contact with product may cause tissue freezing.
INHALATION EFFECTS:
Product is a non-toxic simple asphyxiant. Effects of oxygen deficiency resulting from simple asphyxiants may include: rapid breathing, diminished mental alertness, impaired muscular coordination, faulty judgement, depression of all sensations, emotional instability, and fatigue. As asphyxiation progresses, nausea, vomiting, prostration, and loss of consciousness may result, eventually leading to convulsions, coma, and death.
Oxygen deficiency during pregnancy has produced developmental
abnormalities in humans and experimental animals.

4. First Aid Measures
EYES:
Never introduce ointment or oil into the eyes without
medical advice! In case of freezing or cryogenic "burns" caused by rapidly
evaporating liquid, DO NOT WASH THE EYES WITH HOT OR EVEN TEPID WATER!
Remove victim from the source of contamination. Open eyelids wide to allow
liquid to evaporate. If pain is present, refer the victim to an ophthalmologist
for treatment and follow up. If the victim cannot tolerate light, protect
the eyes with a light bandage.
SKIN:
For dermal contact or frostbite: Remove contaminated clothing and flush affected areas with lukewarm water. DO NOT USE HOT WATER. A physician should see the patient promptly if the cryogenic "burn" has resulted in blistering of the dermal surface or deep tissue freezing.
INGESTION:
A physician should see the patient promptly if the cryogenic "burn" has resulted in blistering of the dermal surface or deep tissue freezing.
INHALATION:
PROMPT MEDICAL ATTENTION IS MANDATORY IN ALL CASES OF
OVEREXPOSURE. RESCUE PERSONNEL SHOULD BE EQUIPPED WITH SELF-CONTAINED BREATHING
APPARATUS. Victims should be assisted to an uncontaminated area and inhale
fresh air. Quick removal from the contaminated area is most important.
Unconscious persons should be moved to an uncontaminated area, and if breathing
has stopped, administer artificial resuscitation and supplemental oxygen.
Further treatment should be symptomatic and supportive.

EXTINGUISHING MEDIA:
None required. Use as appropriate for surrounding materials.
6. Accidental Release Measures
Evacuate all personnel from affected area. Use appropriate
protective equipment. If leak is in container or container valve, contact
the appropriate emergency telephone number listed in Section 1 or call
your closest BOC location.
7. Handling and Storage
Electrical classification:
Non-hazardous.
This gas mixture is noncorrosive and may be used with all common structural materials.
Use only in well-ventilated areas. Valve protection caps must remain in place unless container is secured with valve protection outlet piped to use point. Do not drag, slide or roll cylinders. Use a suitable hand truck for cylinder movement. Use a pressure reducing regulator when connecting cylinder to lower pressure (<3000 psig) piping or systems. Do not heat cylinder by any means to increase the discharge rate of product from the cylinder. Use a check valve or trap in the discharge line to prevent hazardous back flow into the cylinder.
Protect cylinders from physical damage. Store in cool, dry, well-ventilated area of non-combustible construction away from heavily trafficked areas and emergency exits. Do not allow the temperature where cylinders are stored to exceed 125oF (52oC). Cylinders should be stored upright and firmly secured to prevent falling or being knocked over. Use a "first in-first out" inventory system to prevent full cylinders being stored for excessive periods of time.
For additional recommendations, consult Compressed Gas Association Pamphlets P-1, P-14, P-9, and Safety Bulletin SB-2.
Never carry a compressed gas cylinder or a container of
a gas in cryogenic liquid form in an enclosed space such as a car trunk,
van or station wagon. A leak can result in a fire, explosion, asphyxiation
or a toxic exposure.

Refer to individual state or provincial regulations, as applicable, for limits which may be more stringent than those listed here.
ENGINEERING CONTROLS:
Local exhaust to prevent accumulation of high concentrations so as to reduce the oxygen level in the air to less than 19.5%.
EYE/FACE PROTECTION:
Safety goggles or glasses as appropriate for the job. Faceshield recommended when handling cryogenic liquid material.
SKIN PROTECTION:
Protective gloves of material appropriate for the job. Insulated gloves recommended when handling cryogenic liquid material.
RESPIRATORY PROTECTION:
Positive pressure air line with full-face mask and escape bottle or self-contained breathing apparatus should be available for emergency use.
OTHER/GENERAL PROTECTION:
Safety shoes or other footwear as appropriate for the
job.
