WARNING: Be aware that with odorized product the intensity of ethyl mercaptan stench (its odor) may fade due to chemical
oxidation (in the presence of rust, air or moisture), adsorption or absorption. Some people have nasal perception problems
and may not be able to smell the ethyl mercaptan stench. Other odors may mask or hide the ethyl mercaptan stench. While
ethyl mercaptan may not impart the warning of the presence of propane in every instance, it is generally effective in a majority
of situations. Familiarize yourself, and your customers, with this warning, and other facts associated with the so-called "odor -
fade phenomenon". If you would like additional information about odor fade or other safety considerations associated with the
handling, storage and use of propane, please call Phillips Propane Marketing office at 1 -800-662-6033, Option 3.
3. HAZARDS IDENTIFICATION
Emergency Overview
Extremely Flammable - Gas. Compressed Gas. Freeze Burns. Lung - Simple Asphyxiant.
Propane HD -5 Grade Page 2 of 6
Potential Acute Health Effects
Eye Contact: Liquefied gas may cause freeze burns upon direct contact.
Skin Contact: Liquefied gas may cause freeze burns upon direct contact.
Inhalation: Simple asphyxiant. Extreme overexposure may produce dizziness, headache,
disorientation, excitation, fatigue, inability to concentrate, vomiting, coughing, anesthesia,
unconsciousness and death.
Ingestion: Not a likely exposure route. Liquefied gas may cause freeze burns to the mucous
membranes and possible central nervous system depression.
Aggravated Medical Skin Disorders.
Conditions:
4. FIRST AID MEASURES
NOTE: For freeze burns, immediately flush affected area with tap water for at least fifteen minutes, seek
immediate medical attention.
Eye Contact: Flush eyes with running water. If irritation or adverse symptoms develop, seek medical
attention.
Skin Contact: Wash skin with soap and water. If irritation or adverse symptoms develop, seek medical
attention.
Inhalation: Immediately remove from exposure. If breathing is difficult, give oxygen. If breathing
ceases, administer artificial respiration followed by oxygen. Seek immediate medical
attention.
Ingestion: If illness or adverse symptoms develop, seek medical attention.
5. FIRE FIGHTING MEASURES
Emergency Response Guidebook ID No. 1978, Guide No. 115
Flash Point: -156F (-104C)
FP Method: Estimated
Ignition Temperature: Unknown
Flammable Limits (% by Volume in Air)
Lower Explosive Limit - 2.1
Upper Explosive Limit - 9.5
Fire Extinguishing Media: Carbon Dioxide, Dry Chemicals, Foam
Fire Fighting Procedures: Evacuate area and fight fire from a safe distance. Use NIOSH approved self-
contained breathing apparatus and other protective equipment and/or garments
described in Section 8 if conditions warrant. Shut off source, if possible. Use water
spray to cool nearby containers and structures exposed to fire. Allow fire to burn
until gas flow is shut off, if possible.
Fire and explosion hazards: Carbon and Sulfur oxides are released when burned. Highly flammable vapors
which are heavier than air may accumulate in low areas and/or spread along
Propane HD -5 Grade Page 3 of 6
ground away from handling site. Flash back along vapor trail is possible. Heated
containers may rupture violently and suddenly without warning due to pressure
(BLEVE). Fragmentation of the container should be anticipated. If flame is against
the container, withdraw immediately on hearing a hissing sound, if venting
increases in volume or intensity, or if there is discoloration of the tank due to fire.
6. ACCIDENTAL RELEASE MEASURES
Evacuate area of all unnecessary personnel. Wear protective equipment and/or garments described in Section 8
exposure conditions warrant. Shut off source, if possible and contain spill. Protect from ignition. Keep out of water
sources and sewers. Recover as much bulk liquid as possible, by pumping into suitable containers, taking
precautions to prevent sparks or other ignition sources (such as, proper bonding and grounding of containers and
transfer equipment). If absorbent is used, promptly place in sealed containers to control odors.
Spill residues and contaminated soil may be deodorized using dilute (5%) aqueous solutions of bleach (sodium
hyprochlorite). Do not use concentrated or dry bleach. Do not attempt to neutralize or deodorize bulk liquid
mercaptan. Concentrated bleach will cause heating and possible ignition. Attempts to neutralize bulk liquid
mercaptan with bleach solutions will be ineffective and only serve to increase the amount of liquid to dispose.
7. HANDLING AND STORAGE
DO NOT breathe vapor, mist, fume or dust. DO NOT get liquefied gas in eyes, on skin, or on clothing. May cause
freeze burns upon direct contact. Wear protective equipment and/or garments described in Section 8 if exposure
conditions warrant. Wash thoroughly after handling. Launder contaminated clothing before reuse. Use only with
adequate ventilation.
Keep away from heat, sparks, and flame. Store in well-ventilated area. Bond and ground during transfer. Store in
tightly closed container. DO NOT puncture or incinerate container. Secure container to prevent damage.
NOTE: Store in containers that have been properly purged and passified. (Oxidation of ethyl mercaptan may
occur in the presence of rust, air, or water.)
8. EXPOSURE CONTROLS/PERSONAL PROTECTION
Eye Protection: Use safety glasses with side shields and a face shield.
Respiratory Protection: For concentrations exceeding an applicable exposure limit, use NIOSH approved
air purifying respirator equipped with:
- Organic vapor cartridges.
Air purifying respirators should NOT be used in:
- Situations that exceed the maximum use concentrations of the respirator or air-
purifying element established by regulatory standards.
- Atmospheres containing less than 19.5 percent oxygen.
- Atmospheres immediately dangerous to life or health (IDLH)
For concentrations exceeding the recommended exposure level, use NIOSH
approved air purifying respirator. In case of spill or leak resulting in unknown
concentration, use NIOSH approved supplied air respirator. If conditions
immediately dangerous to life or health (IDLH) exist, use NIOSH approved self-
contained breathing apparatus (SCBA).
Skin Protection: Wear protective garments to prevent skin contact and freeze burns.
Ventilation: Use adequate ventilation to control concentrations below applicable exposure
limits.

Other Personal Protection: Personal protection information shown in Section 8 is based upon general
information as to normal uses and conditions. Where special or unusual uses or
conditions exist, it is suggested that the expert assistance of an industrial hygienist
or other qualified professional be sought.
Odor Fading: See WARNING information in Section 2.

11. TOXICOLOGICAL INFORMATION
Subchronic and Chronic Effects:
Laboratory animals have exhibited a higher degree of narcosis when exposed to both butane and butylene
(additive effect), than the degree of narcosis exhibited following exposure to butane or butylene alone.
Isobutane did not produce kidney damage in male rats after 21 days of inhalaing 1,000 ppm of butane in
hydrocarbon mixtures of a total > 4,400 ppm or repeat inhalation exposure (90 days) to 4,500 ppm or 1,000 ppm
of both pentane and butane mixed in equal parts. Exposure to 1000 ppm propane for eight hours a day, five days
a week, for approximately two weeks showed no abnormal cardiac, pulmonary or neurologic functions in humans.
Propylene was not carcinogenic to rats or mice chronically exposed to concentrations of 5,000 ppm or 10,000
ppm. Subchronic exposure of rats to unspecificed concentrations of Propylene vapor for 1 - 2 months was
reported to produce eye disturbances.
Humans breathing 1000 ppm of propane for eight hours a day, five days a week, for approximately two weeks
showed no abnormal effects in their cardiac, pulmonary or neurologic functions.
