EMERGENCY OVERVIEW

DANGER!

HEALTH HAZARDS

ASPHYXIANT GAS

MAY REDUCE THE OXYGEN AVAILABLE FOR BREATHING

OVEREXPOSURE MAY CAUSE CNS DEPRESSION

BREATHING HIGH CONCENTRATIONS CAN CAUSE IRREGULAR HEARTBEATS WHICH MAY BE FATAL

DIRECT CONTACT WITH GAS UNDER PRESSURE MAY CAUSE FROSBITE(COLD BURNS)

SEE “TOXICOLOGICAL INFORMATION” (SECTION 11) FOR MORE INFORMATION

FLAMMABILITY HAZARDS

FLAMMABLE COMPRESSED GAS/LIQUID

MAY CAUSE FLASH FIRE OR EXPLOSION

REACTIVITY HAZARDS

STABLE

POTENTIAL HEALTH EFFECTS, SKIN

Direct contact with compressed gas may cause frostbite (coldburns) and skin damage. Short term contact may result in tissue distruction and severe burns.

POTENTIAL HEALTH EFFECTS, EYE

Direct contact with compressed gas may cause eye damage

POTENTIAL HEALTH EFFECTS, EYE

Simple asphyxiate which can cause unconsciousness/death if OXYGEN levels are sufficiently reduced.

Breathing high concentrations may be harmful. May cause central nervous system depression or effects. Symptoms may include headache, excitation, euphoria, dizziness, incoordination, drowsiness, light-headedness, blurred vision, fatigue, tremors, convulsions, loss of consciousness, coma, respiratory arrest and death, depending on the concentration and duration of exposure.

Breathing high concentrations of this material, for example, in a confined space or by intentional abuse, can cause irregular heartbeats which can cause death.

Overexposure to this material may cause systemic damage including target organ effects listed under “Toxicological Information” (Section 11)

POTENTIAL HEALTH EFFECTS, INDEGESTION

Not a normal route of exposure

*Values do not reflect absolute minimums and maximums; these values are typical which may vary from time to time.

COMPOSITION COMMENTS

This Material Safety Data Sheet is intended to communicate potential health hazards and potential physical hazards associate with the product(s) covered by this sheet, and is not intended to communicate product specification information. For product specification information, contact your Flint Hills Resources, LP representative.

SKIN

For frostbite or freeze burns, keep affected area warm by immersing or flushing with warm water. GET IMMEDIATE MEDICAL ATTENTION

EYE

Flush immediately with large amounts of water for at least 15 minutes. Eyelids should be held away from the eyeball to ensure thorough rinsing. GET IMMEDIATE MEDICAL ATTENTION

INHALATION

Remove to fresh air. If not breathing, institute rescue breathing. If breathing is difficult, ensure airway is clear and give oxygen. If heart has stopped, immediately begin cardiopulmonary resuscitation (CPR).

Keep affected person warm and at rest. GET IMMEDIATE MEDICAL ATTENTION

INGESTION

Due to the volatile nature of this material, ingestion is not a likely route of exposure.

NOTES TO PHYSICIAN

INHALATION: This material (or a component) sensitizes the myocardium to the effects of sympathomimetic amines. Epinephrine and other sympathomimetic drugs may initiate cardiac arrhythmias in individuals exposed to this material. Administration of sympathomimetic drugs should be avoided.

HAZARDOUS COMBUSTION PRODUCTIONS

Combustion may produce hazardous combustion products such as COx and SOx.

EXTINGUISHING MEDIA

Use dry chemical, carbon dioxide, water spray or fog to extinguish fire.

BASIC FIRE FIGHTING PROCEDURES

Shut off Source of flow if possible. Do not attempt to extinguish fire if gas source cannot be shut off first.

Evacuate area and fight fire from a safe distance.

If leak or spill has not ignited, ventilate area and use water spray to disperse gas or vapor and to protect personnel attempting to stop a leak. Use water spray to cool adjacent structures and to protect personnel.

Containers can build up pressure if exposed to heat (fire). Stay away from storage tank ends. Withdraw immediately in case of rising sound from venting safety device or any discoloration of storage tank due to fire.

Be aware that a BLEVE(Boiling Liquid Expanding Vapor Explosion) may occur unless surfaces are kept cool with water.

Firefighters must wear NIOSH approved positive pressure breathing apparatus (SCBA) with full face mask and full protective equiptment.

UNUSUAL FIRE & EXPLOSION HAZARDS

Extremely flammable. Vapors form flammable or explosive mixture with air at room temperature. Vapor or gas may spread to distant ignition sources and flash back.

Explosion hazard if exposed to extreme heat.

• Flash point-156 F (-104.4 C)
• Autoignition Temperature842 F (450.0 C)
• Flammability Limits in Air, Lower, % by Volume2%
• Flammability Limits in Air, Upper, % by Volume9.5%
