Symptoms may include headache, excitation, euphoria, dizziness, incoordination, drowsiness, iight-headedness, blurred vision, fatigue, tremors, convulsions, loss of consciousness, coma, respiratory arrest and death, depending on the concentration and duration of exposure.

  May cause cardiac sensitization, including arrhythmias (irregular heart beats) and death due to cardiac arrest.

  Overexposure to this material may cause systemic damage including target organ effects listed under "Special Toxic Effects."

  Other specific symptoms of exposure are listed under "Special Toxic Effects."

POTENTIAL HEALTH EFFECT, INGESTION
  Not a normal route of exposure.

SPECIAL TOXIC EFFECTS
  Acute or chronic overexposure to this material or its components may cause systemic toxicity, including adverse effects to the following: cardiovascular and central nervous systems.

  Contains asphyxiant which may cause reproductive and/or developmental effects in pregnant women.

  Pre-existing medical conditions which may be aggravated by exposure include disorders of the respiratory and cardiovascular systems.

HAZARDOUS COMBUSTION PRODUCTS
  Combustion may produce COx, NOx, SOx, reactive hydrocarbons and irritating vapors.

EXTINGUISING MEDIA
   Use water spray, dry chemical, alcohol foam, all purpose AFFF or carbon dioxide 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 MSHA/NIOSH approved positive pressure breathing apparatus (SCBA) with full face mask and full protective equipment.

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

  Explosion hazard if exposed to extreme heat or to physical or thermal shock.

  Fires involving this product may release COx, NOx, SOx, reactive hydrocarbons and irritating vapors.

  Flash Point -156 F (-104 C)
   Autolgnition Temperature 842 F (450 C)
   Flammability Limits in Air, Lower, % by Volume 2 %
   Flammability Limits in Air, Upper, % by Volume g 5 %

SPILL OR LEAK PROCEDURE
  Keep ignition sources out of area and shut off all ignition sources. Isolate spill area and keep unnecessary people away. Use water spray to reduce vapors. Stop leak when safe to do so.

  See Exposure Controls/Personal Protection (Section 8).

HANDLING
  Ground lines and equipment used during transfer to reduce the possibility of static spark-initiated fire or explosion. Use non-sparking tools. Do not cut, grind, drill, weld or reuse containers unless adequate precautions are taken against these hazards. Do not eat, drink or smoke in areas of use or storage.

STORAGE
  Store in tightly closed containers in a cool, dry, isolated, well-ventilated area away from heat, sources of ignition and incompatibles. Avoid contact with strong oxidizers. Empty containers may contain product residue. Do not reuse without adequate precautions. Do not eat, drink or smoke in areas of use or storage.

ENGINEERING CONTROLS
  Ventilation and other forms of engineering controls are the preferred means for controlling exposures.

EYE PROTECTION: PERSONAL PROTECTION EQUIPMENT (PPE)
  Wear safety glasses with side shields. A means for quick drenching or flushing of the eyes should be provided for first aid purposes.

SKIN PROTECTION: PERSONAL PROTECTION EQUIPMENT (PPE)
   Avoid skin contact with this material. Use appropriate chemical protective gloves when handling. Use good personal hygiene.

RESPIRATORY PROTECTION: PERSONAL PROTECTION EQUIPMENT (PPE)
  A NIOSH/MSHA approved air purifying respirator with an organic vapor cartridge or canister may be permissible under certain circumstances where airborne concentrations are expected to exceed exposure limits. Protection provided by air purifying respirators is limited. Use a positive pressure air supplied respirator if there is any potential for an uncontrolled release, exposure levels are not known, or any other circumstances where air purifying respirators may not provide adequate protection.

STABILITY / INCOMPATABILITY
  Incompatible with oxidizing agents. See precautions under Handling & Storage (Section 7).

HAZARDOUS REACTIONS / DECOMPOSITION PRODUCTS
  Combustion may produce COx, NOx, SOx, reactive hydrocarbons and irritating vapors.

MISCELLANEOUS

This product has been malodorized to facilitate its identifiability. It has been determined that the odorant can diminish or fade due to exposure to oxidized substances, including the following:
1. Adsorption ("sticking") of the odorant molecules to the inside surface of metal storage containers and pipes, particularly (i) those that are new; (ii) those whose interior surfaces have been exposed to the atmosphere while out of service; or (iii) those whose interior surfaces are rough.
2. The presence of ordinary red rust (iron or ferric oxide) inside a storage container or piping.
3. Selective absorption ("filtering") of the odorant molecules by soil in the case of underground leaks.
4. Absorption of the odorant molecules on the walls (particularly those made of rough woods, rock or any other types of masonry) or on the fabric of draperies, furniture or carpets in rooms where there is little or no air circulation.

Physical and environmental conditions such as competing odors, common colds, allergies, or smoking may lessen a person's ability to smell the odorant. In addition, prolonged exposure to the odorant or exposure to extremely high concentrations of the odorant can diminish a person's ability to smell the odorant. Finally, some individuals are not capable of smelling the odor emitted by the odorant.

All product users and handlers should acquaint themselves with what they determine to be the usual odor of odorized product. Further, as such individuals use or handle the product, proper precautions should be taken to ensure that the exposure of the product to substances such as those identified above is eliminated or to properly passivate such substances prior to use. Frequent sniff tests should be conducted. Handlers and retailers of the product should conduct periodic stain tube or other testing to ensure proper levels of the odorant are maintained and documented. Special attention should be focused on storage or transportation systems which exhibit the characteristics described above. In the event a lower level of odorant than required by law is discovered pursuant to the stain tube or other testing, additional odorant, or additional, properly odorized propane, should be added.

Purchaser and all downstream individuals who engage in the re-selling of product should continually communicate, inform, and train their employees, customers, and the public at large regarding the characteristics and hazards of the product, including specifically the possible failure of the odorant warning system under certain circumstances.
