% by Volume Isolate source. Use water spray, dry chemical,
LEL - 1.6% UEL - 8.4% foam or carbon dioxide.
Special Fire Fighting Procedures:
Evacuate the area for at least 1/2 mile in all directions if rail car or tank truck is involved in fire. Use
water to keep fire-exposed containers cool. If containers experience flame or heat impingement, cool
immediately to prevent BLEVE (Boiling Liquid Expanding Vapor Explosion) Always approach from
sides and never from the ends. If leak or spill has not ignited, use water spray to disperse the vapors and
to provide protection for personnel attempting to stop a leak. Water spray may be used to flush spills
away from exposures.
Unusual Fire and Explosion Hazards:
Products of combustion may contain carbon monoxide, carbon dioxide and other toxic materials. Do not
enter enclosed or confined space without proper protective equipment including respiratory protection.

Conditions and Materials to Avoid Hazardous Decomposition Products
Oxidizing materials, flame, heat. Incomplete combustion may produce carbon
monoxide.
OCCUPATIONAL EXPOSURE LIMITS
OSHA PEL Not determined for this product - 8 Hr. TWA ACGIH = 800 ppm.
HEALTH INFORMATION
Acute Exposure
Inhalation may produce rapid breathing, headache, dizziness visual disturbances, muscular weakness,
tremors, narcosis, unconsciousness, and death, depending upon concentration and duration of exposure.
Contact with the eyes, skin, or other tissues with the gas may cause freeze burns (frostbite).
Eye Contact Skin Contact
Vapors are not expected to present an eye Material is not expected to be absorbed through the
irritation hazard but contact with gas or ice skin, however contact with evaporating gas may cause
ice crystals may cause freeze burns of the eye. freeze burns.
Inhalation Ingestion
Inhalation may produce rapid breathing, Solid and Liquid forms of this material and the
headache, dizziness visual disturbances, pressurized gas can cause freeze burns.
muscular weakness, tremors, narcosis,
unconsciousness, and death, depending upon
concentration and duration of exposure.

Chronic Effects
Pre-existing respiratory conditions may be aggravated by exposure to this material. Persons with such
respiratory conditions should avoid contact with this material.
EMERGENCY AND FIRST AID PROCEDURES
Eyes
No irritating properties are known for this material. If freeze burns to the eyes occur. flush with warm
water for at least 15 minutes. Contact physician.
Skin
Frozen tissues should be flooded with warm (not hot) water. Cryogenic burns, which result in blistering
or deeper tissue freezing, should be seen promptly by a physician.
Inhalation
Remove to fresh air. Restore breathing if necessary. Administer oxygen if breathing difficulty persists
and contact physician for treatment.
Ingestion
INDUCE VOMITING with warm water (one quart) only if patient is fully conscious. Contact physician
for immediate treatment.
EMPLOYEE PROTECTION
Respiratory
In the event of a spill or release use a positive pressure / pressure demand self-contained breathing
apparatus (SCBA) or airline respirator as approved by MSHA-NIOSH.
Eye
Splash goggles and face shield when eye contact may occur.
Gloves
Use impervious plastic or neoprene-coated canvas gloves.
Other Clothing
Use chemical resistant apron or other clothing, to protect skin from contact with liquids or gases.
Ventilation
Local exhaust - In closed areas - Use of explosion proof electrical equipment (Class I, Division 1 Group
D) mechanical ventilation equipment recommended.
Other Protective Measures
Emergency eyewash should be available in areas where materials are routinely transferred.
ENVIRONMENTAL PROTECTION
Storage
Store product in containers appropriate for its flammability/combustibility.
Spill Cleanup Procedure
Report spills to appropriate authorities. In case of accident or road spill, notify Chemtrec (800) 424-
9300. If spill could reach any waterway, including intermittent dry stream beds, immediate notification
of Coast Guard is required - (800) 424-8802.

Spill or Leak
Eliminate all ignition sources. Eliminate source of release or spill if possible. Located all personnel
upwind of spill. If rail car or tank truck is involved in fire evacuate in all directions for 1/2 mile. Stop
source of release before extinguishing any fire. Ventilate enclosed areas to prevent the formation of
explosive or oxygen deficient atmospheres. Water spray may be used to reduce vapor concentrations.
Closed systems may form white frost at the point of the leak. Liquid spills will vaporize forming cold,
dense vapor clouds that do not readily disperse. Avoid vapor cloud even with proper respiratory
equipment. The fire department should be notified immediately.
Waste Disposal
Releases are expected to cause only localized non-persistent environmental damage. Waste mixtures
containing these gases should not be allowed to enter drains or sewers where there is a danger of their
vapors becoming ignited. When it becomes necessary to dispose of these gases, it is preferable to do so as
a vapor. Unused product may be used as an auxiliary fuel or disposed by burning in a properly designed
flare or incinerator. Venting of gas to the atmosphere should be avoided. Defective, empty, or partially
used portable containers should be returned to the supplier with appropriate tags.
SPECIAL PROTECTION
Do not store or use near strong oxidizing agents, flames, sparks or hot surfaces. Store in tightly sealed
containers in clean, well-ventilated areas. Bond and ground metal containers for liquid transfer. Do not
smoke in areas of handling or use.
