LD50: None. LC50: None.
03. HAZARDS IDENTIFICATION

EMERGENCY OVERVIEW:

Warning:
Flammable liquid gas under pressure.

Can form explosive mixtures with air.

May cause frostbite.

Potential Health Effects Information:

Routes of Exposure:

Inhalation:
Simple asphyxiant. It should be noted that before suffocation could occur, the lower

flammability limit of propane in air would be exceeded; possibly causing both an

oxygen-deficient and explosive atmosphere. Exposure to concentrations (> 10%)

may cause dizziness. Exposure to atmospheres containing 8-10% or less oxygen

will bring about unconsciousness without warning, and so quickly that the individuals

cannot help or protect themselves. Lack of sufficient oxygen may cause serious

injury or death.

Eye Contact:
Contact with liquid or cold vapor can cause freezing of tissue.

Skin Contact:
Contact with liquid or cold vapor can cause frostbite.

Chronic Effects:
None.

Medical Conditions Aggravated By
None.

Overexposure:

Other Effects Of Overexposure:
None.

Carcinogenicity:
Propane is not listed by NTP, OSHA or IARC.
04. FIRST AID MEASURES

Inhalation:
Persons suffering from lack of oxygen should be removed to fresh air. If victim is

not breathing, administer artificial respiration. If breathing is difficult, administer

oxygen. Obtain prompt medical attention.

Eye:
Contact with liquid or cold vapor can cause freezing of tissue. Gently flush eyes

with lukewarm water. Obtain medical attention immediately.

Skin:
Contact with liquid or cold vapor can cause frostbite. Immediately warm affected

area with lukewarm water not to exceed 105°F (40°C).

Ingestion:
None.

Notes To Physician:
None.
05. FIRE FIGHTING MEASURES

Flash Point:
-156F (-104C)

Autoignition:
842F (432C)

Flammable Limits - Lower:
2.2%

Flammable Limits - Upper:
9.5%

Extinguishing Media:
CO2, dry chemical, water spray or fog for surrounding area. Do not extinguish until

propane source is shut off.

Fire Fighting Instructions:
Evacuate all personnel from danger area. Immediately cool container with water

spray from maximum distance, taking care not to extinguish flames. If flames are

accidentally extinguished, explosive re-ignition may occur. Stop flow of gas if

without risk while continuing cooling water spray.

Fire And Explosion Hazards:
Propane is easily ignited. It is heavier than air, therefore, it may collect in low areas

or travel along the ground where an ignition source may be present. Pressure in a

container can build up due to heat, and it may rupture if pressure relief devices

should fail to function.

Hazardous Combustion Products:
None known.

Sensitivity To Static Discharge:
Possible, container should be grounded.

Sensitivity To Mechanical Impact:
None.
06. ACCIDENTAL RELEASE MEASURES

Evacuate:
Evacuate the immediate area. Eliminate any possible sources of ignition, and

provide maximum explosion-proof ventilation. Shut off source of propane, if

possible. If leaking from cylinder, or valve, contact your supplier. Never enter a

confined space or other area where the concentration is greater than 10% of the

lower flammable limit which is 0.22%.
07. HANDLING AND STORAGE

Storage:
Specific requirements are listed in NFPA 58. Cylinder storage locations should be

well-protected, well-ventilated, dry, and separated from combustible materials.

Cylinders should never knowingly be allowed to reach a temperature exceeding

125°F (52°C). Cylinders of propane should be separated from oxygen cylinders or

other oxidizers by a minimum distance of 20 ft., or by a barrier of non-combustible

material at least 5 ft. high having a fire resistance rating of at least ½ hour. Full and

empty cylinders should be segregated. Use a first-in, first-out inventory system to

prevent full containers from being stored for long periods of time.



Cylinders should be stored upright with valve protection cap in place and firmly

secured to prevent falling or being knocked over. Protect cylinders from physical

damage; do not drag, roll, slide or drop. Use a suitable hand truck for cylinder

movement. Post "No Smoking or Open Flames" signs in the storage areas. There

should be no sources of ignition. All electrical equipment should be explosion proof

in the storage and use areas. Storage areas must meet national electric codes for

class 1 hazardous areas.

Handling:
Propane is heavier than air and may collect in low areas that are without proper

ventilation. Leak check system with leak detection solution, never with flame. If

user experiences difficulty operating cylinder valve, discontinue use and contact

supplier. Never insert an object (e.g., wrench, screwdriver, pry bar, etc.) into valve

cap openings. Doing so may damage valve, causing a leak to occur. Use an

adjustable strap wrench to remove over-tight or rusted caps. Non-sparking tools

should be used. Never strike an arc on a compressed gas cylinder or make a

cylinder a part of an electrical circuit. Electrically bond and ground cylinder when

transferring liquid product. For additional precautions in using propane see Section

16 - Other Information.
08. EXPOSURE CONTROLS - PERSONAL PROTECTION

Engineering Controls:

Ventilation:
Natural or mechanical to prevent accumulation in worker's breathing zone above

exposure limits. (See Section 2).

Personal Protective Equipment (PPE):

Clothing:
Cotton Clothing is recommended for use to prevent static electric buildup.

Glasses:
Safety glasses are recommended when handling cylinders.

Shoes:
Safety shoes are recommended when handling cylinders.

Gloves:
Work gloves are recommended when handling cylinders.

Respirator:
None required in general use.

Emergency Use:
Self-contained breathing apparatus (SCBA) or positive pressure airline with mask

are to be used in oxygen-deficient atmosphere. Respirators will not function.

Before entering area, you must check for flammable and oxygen deficient

atmospheres.
